Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Summary of Accounting Policies All amounts included herein related to these unaudited condensed consolidated financial statements as of September 30, 2015 and the three and nine months ended September 30, 2015 and 2014 are unaudited and should be read in conjunction with the audited consolidated financial statements and the notes thereto included in Callidus Software Inc.'s ("Company") Annual Report on Form 10-K for the year ended December 31, 2014 . Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to the Securities and Exchange Commission ("SEC") rules and regulations regarding interim financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all necessary adjustments for the fair presentation of the Company’s financial position, results of operations and cash flows. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the full fiscal year ending December 31, 2015. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, which include wholly-owned subsidiaries in Australia, Canada, Germany, Hong Kong, India, Japan, Malaysia, Mexico, New Zealand, Serbia, Singapore, and the United Kingdom. All intercompany transactions and balances have been eliminated upon consolidation. Use of Estimates Preparation of the unaudited condensed consolidated financial statements in conformity with GAAP and the rules and regulations of the SEC requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, the reported amounts of revenue and expenses during the reporting period and the accompanying notes. Estimates are used for, but not limited to, uncertain tax liabilities, allowances for doubtful accounts, the useful lives of fixed assets and intangible assets, goodwill and intangible asset impairments, stock-based compensation forfeiture rates, accrued liabilities, the allocation of the value of purchase consideration for business acquisitions, and other contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates such estimates and assumptions on an ongoing basis for continued reasonableness, using historical experience and other factors, including the current economic environment. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such evaluation. Illiquid credit markets, volatile equity and foreign currency markets and fluctuations in information technology spending by prospective customers can increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates. Changes in those estimates, if any, resulting from continuing changes in the economic environment, will be reflected in the condensed consolidated financial statements in future periods. Revenue Recognition The Company generates revenue by providing software applications as a service ("SaaS") through an on-demand subscription, on-premise perpetual and term licenses and related software maintenance, and professional services. Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Recurring Revenue. Recurring revenue, which includes software-as-a-service revenue and maintenance revenue, is recognized ratably over the stated contractual period. SaaS revenue consists of subscription fees from customers accessing our cloud-based service offerings. Maintenance revenue consists of fees from customers purchasing support for on-premise solutions. The Company also recognizes revenue associated with customers using its products in excess of contracted usage ("Overages"). Overages are primarily attributed to SaaS products and such Overages are recorded in SaaS revenue. Revenue related to Overages was immaterial during the three and nine months ended in September 30, 2015 and September 30, 2014 . Service and License Revenue. Service and license revenue primarily consist of training, integration and configuration services. Generally, the Company's professional services arrangements are on a time-and-materials basis. Time and material services are recognized as the services are rendered based on inputs to the project, such as billable hours incurred. For fixed-fee professional service arrangements, the Company recognizes revenue under the proportional performance method of accounting and estimates the proportional performance on a monthly basis, utilizing hours incurred to date as a percentage of total estimated hours to complete the project. If the Company does not have a sufficient basis to measure progress toward completion, revenue is recognized upon completion. Service and license revenue also includes revenue from perpetual licenses, which is recognized upon delivery of the product, using the residual method, assuming all the other conditions for revenue recognition have been met. In a limited number of arrangements with non-standard acceptance criteria, the Company defers the revenue until the acceptance criteria is satisfied. Reimbursements, including those related to travel and out-of-pocket expenses, are included in services and license revenue, and an equivalent amount of reimbursable expenses is included in cost of services and license revenue. In general, recurring revenue agreements are entered into for 12 to 36 months, and the professional services are performed within nine months of entering into a contract with the customer, depending on the size of integration. SaaS agreements provide specified service level commitments, excluding scheduled maintenance. The failure to meet this level of service availability may require the Company to credit qualifying customers a portion of their subscription and support fees. Based on the Company's historical experience meeting its service level commitments, the Company does not currently have any liabilities on its balance sheet for these commitments. The Company recognizes revenue when all of the following conditions are met: • Persuasive evidence of an arrangement exists; • Delivery has occurred or services have been rendered; • The fees are fixed or determinable; and • Collection of the fees is reasonably assured. If the Company determines that any one of the four criteria is not met, it will defer recognition of revenue until all the criteria are met. Multiple-deliverable arrangements with on-demand subscription. For on-demand subscription agreements with multiple-deliverables, the Company evaluates each element to determine whether it represents a separate unit of accounting. The Company determines the best estimated selling price of each deliverable in an arrangement based on a selling price hierarchy of methods contained in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2009-13, Revenue Recognition (Accounting Standards Codification (“ASC”) Topic 605)- Multiple-Deliverable Revenue Arrangements. The best estimated selling price for a deliverable is based on its vendor-specific objective evidence (“VSOE”), if available, third-party evidence (“TPE”), if VSOE is not available, or estimated selling price (“ESP”), if neither VSOE nor TPE is available. Total arrangement fees are allocated to each element using the relative selling price method. The Company has currently established VSOE for most deliverables, except for fixed fee service arrangements and on-premise software licenses. The Company considered all of the following factors to establish the ESP for fixed fee service arrangements when sold with its on-demand services: the weighted average actual sales prices of professional services sold on a stand-alone basis for on-demand services; average billing rates for fixed fee service agreements when sold with on-demand services, cost plus a reasonable mark-up and other factors such as gross margin objectives, pricing practices and growth strategy. The Company is currently using cost plus a reasonable mark-up to establish ESP for fixed fee service arrangements. Multiple-deliverable arrangements with on-premise license. For arrangements with multiple-deliverables, including license, professional services and maintenance, the Company recognizes license revenue using the residual method of accounting pursuant to the requirements of the guidance contained in ASC 985-605, Software Revenue Recognition . Under the residual method, revenue is recognized when VSOE for fair value exists for all of the undelivered elements in the arrangement, but does not exist for one or more of the delivered elements in the arrangement. If evidence of fair value cannot be established for the undelivered elements, all of the revenue is deferred until evidence of fair value can be established, or until the items for which evidence of fair value cannot be established are delivered. For maintenance and certain professional services, the Company has established VSOE as a high number of stand-alone sales of this deliverable have been priced within a reasonably narrow range. The Company's revenue arrangements do not include a general right of return relative to the delivered products. For the Company's term-based licenses, if the only undelivered element is maintenance, the entire amount of revenue is recognized over the maintenance period, because the Company does not sell maintenance separately. Sales and other taxes collected from customers to be remitted to government authorities are excluded from revenue. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09) "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 may also impact how the Company accounts for certain direct costs associated with its revenues. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted one year earlier. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company has not elected a transition method and is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on the condensed consolidated financial statements and does not plan to early adopt this standard.

Business Combinations [Abstract]
Acquisition	Acquisition On July 22, 2015, the Company acquired BridgeFront LLC ("BridgeFront"), a leading provider of cloud-based education content for the healthcare sector, most notably in the compliance and revenue cycle domains. The purchase consideration was approximately $5.1 million , which included approximately $4.4 million paid in cash, $0.1 million held back to cover expenses of the stakeholder representative which is payable in early 2017, and an approximately $0.5 million indemnity holdback payable upon the one year closing anniversary, which remained outstanding as of September 30, 2015. Earn-out payments based on achievement of targets are normally treated as purchase price, however, because of service conditions, $0.5 million of the $0.6 million is treated as compensation expense and recognized over the term of the payments in 2015 and 2016. The fair value of the remaining balance of $0.1 million of the earn-out is recorded as contingent consideration. The preliminary purchase price allocation for BridgeFront is summarized as follows (in thousands): Fair Value Net liabilities assumed $ (849 ) Intangible assets 2,100 Goodwill 3,806 Total purchase price $ 5,057 As of September 30, 2015, the purchase price allocation for the acquisition was preliminary and subject to completion. Adjustments to the current fair value estimates in the above table may occur as the process conducted for the valuation and review is finalized, including assets, liabilities and other attributes. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable assets acquired. The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and the expanded market opportunities of our Litmos mobile learning applications in the healthcare industry. The financial results of BridgeFront are included in the Company's unaudited condensed consolidated financial statements from the date of acquisition to September 30, 2015. The acquisition of BridgeFront did not have a material impact on the Company's unaudited condensed consolidated financial statements and therefore pro forma disclosures have not been presented. The following table sets forth the components of identifiable intangible assets acquired, their weighted-average useful lives over which they will be amortized using the straight-line method, and the classification of their amortized expense in our condensed consolidated statements of operations (in thousands): Fair Value Weighted -Average Useful life Statement of Operations Classification: Amortization Expense Developed technology $ 1,800 5 years Cost of sales Customer relationships 300 5 years Sales and marketing expense Total intangible assets subject to amortization $ 2,100 The fair values of the intangible assets at the acquisition date were measured primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined in ASC 820, Fair Value Measurements. The value of acquired intangibles was determined based on the present value of estimated future cash flows using the following valuation techniques and inputs: • Developed technology - Primarily the royalty-from-relief method using inputs such as estimated revenues attributable to the online education content, estimated net royalty revenue, effective income tax rate and discount rate. • Customer relationships - Primarily the multi-period excess earnings method under the income approach using inputs such as probability-weighted revenue attributable to existing customer relationships, customer attrition, estimated expenses, effective income tax rate, and discount rate. The amortization expense of $0.1 million was included in our unaudited condensed consolidated of operations. The acquisition related costs incurred during the quarter of $0.2 million which was included in general and administration expense in the unaudited condensed consolidated statements of operations.

Financial Instruments	Financial Instruments As of September 30, 2015 and December 31, 2014 , all investment debt securities were classified as available-for-sale and carried at estimated fair value, which is determined based on the inputs discussed below. The Company classifies all highly liquid instruments with an original maturity on the date of purchase of three months or less as cash and cash equivalents. The Company classifies available-for-sale securities that have a maturity date longer than three months as short-term investments, including those investments with a maturity date of longer than one year that are highly liquid and which the Company does not intend to hold to maturity. Realized gains and losses are calculated using the specific identification method. As of September 30, 2015 and December 31, 2014 , the Company had no short-term investments in a material unrealized loss position. The components of the Company’s cash, cash equivalents, and investments classified as available-for-sale were as follows at September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 Amortized Cost Gross Gains Gross Losses Estimated Fair Value Cash $ 75,659 $ — $ — $ 75,659 Cash equivalents: Money market funds 1,458 — — 1,458 Total cash equivalents 1,458 — — 1,458 Total cash and cash equivalents $ 77,117 $ — $ — $ 77,117 Short-term investments: Certificates of deposits $ 1,500 $ — $ — $ 1,500 Corporate notes and U.S government agency obligations 17,098 (1 ) 17,097 Total short-term investments $ 18,598 $ — $ (1 ) $ 18,597 December 31, 2014 Amortized Cost Gross Gains Gross Losses Estimated Fair Value Cash $ 27,890 $ — $ — $ 27,890 Cash equivalents: Money market funds 6,310 — — 6,310 Total cash equivalents 6,310 — — 6,310 Total cash and cash equivalents $ 34,200 $ — $ — $ 34,200 Short-term investments: Corporate notes and U.S. government agency obligations $ 2,773 $ — $ (7 ) $ 2,766 Total short-term investments $ 2,773 $ — $ (7 ) $ 2,766 The market value and the amortized cost of available-for-sale debt securities by contractual maturities as of September 30, 2015 were as follows (in thousands): Contractual maturity Amortized Cost Estimated Fair value Less than 1 year $ 7,755 $ 7,755 Between 1 and 2 years 10,843 10,842 Total $ 18,598 $ 18,597 The Company had no realized gains or losses on sales of its investments for the three and nine months ended September 30, 2015 and 2014. The Company had net purchases of investments of $ 15.9 million during the nine months ended September 30, 2015 and net proceeds from maturities and sales of investments of $ 5.1 million during the nine months ended September 30, 2014. The short-term investments in highly rated credit securities generally have minor to moderate fluctuations in the fair values from period to period. The Company monitors credit ratings, downgrades and significant events surrounding these securities in order to assess whether any of the impairments will be considered other-than-temporary. The Company did not identify any securities held as of September 30, 2015 or as of December 31, 2014 for which the fair value declined significantly below amortized cost and were considered other-than-temporary impairments.

(2) Included in short-term investments on the unaudited condensed consolidated balance sheet. Valuation of Investments Level 1 and Level 2 The Company’s available-for-sale securities include money market funds, certificates of deposit, corporate notes and U.S. government agency obligations. The Company values these securities using a pricing matrix from a pricing service provider, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs). The Company classifies all of its available-for-sale securities, except for money market funds, as having Level 2 inputs. The Company validates the estimated fair value of certain securities from a pricing service provider on a quarterly basis. The valuation techniques used to measure the fair value of the financial instruments having Level 2 inputs, all of which have counterparties with high credit ratings, were derived from the following: non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments or pricing models, such as discounted cash flow techniques, with all significant inputs derived from or corroborated by observable market data. Level 3 Contingent consideration and related liabilities are defined as earn-out payments which the Company may pay in connection with the acquisition of BridgeFront. Contingent consideration and related liabilities are classified as level 3 liabilities, as the Company uses unobservable inputs to value them, which is a probability-based income approach. Subsequent changes in the fair value of contingent consideration and related liabilities will be recorded in the Company's unaudited condensed consolidated statements of operations. The Company did not have any transfers between Level 1, Level 2 and Level 3 fair value measurements during the periods presented as there were no changes in the composition in Level 1, 2 or 3.

Commitments and Contingencies	Commitments and Contingencies Except as discussed below, there were no material changes in the Company's commitments under contractual obligations as disclosed in the Company’s audited consolidated financial statements for the year ended December 31, 2014 . Letter of Credit The Company obtained a $1.1 million letter of credit in October 2014 for leased space in Dublin, California. The letter of credit expired on October 1, 2015 and was automatically renewed for one year to October 1, 2016. There is no balance outstanding under this line of credit. Revolver Line of Credit In May 2014, the Company entered into a credit agreement with Wells Fargo Bank, National Association ("Wells Fargo"), under which Wells Fargo agreed to make a revolving loan ("Revolver") to the Company in an amount not to exceed $ 10.0 million , with an accordion feature that allows the Company to increase the maximum borrowing amount by not less than $ 5.0 million and not more than $10.0 million . In September 2014, the Company increased the maximum borrowing amount to $ 15.0 million . The Revolver matures in May 2019. During the quarter ended June 30, 2015, the Company paid off the outstanding amount of $ 10.5 million . Pursuant to the agreement, the Company is required to maintain a leverage ratio of 3.00 :1.00 and minimum liquidity of $ 7.5 million . The Company has met these leverage and liquidity covenants. Outstanding borrowings under the Revolver bear interest, at the Company's option, at a base rate plus an applicable margin. The applicable margin ranges between 0.75% and 2.25% depending on the Company's leverage ratio. A fee of 0.25% per annum is payable with respect to the unused portion of the commitment. Interest is payable every three months. Warranties and Indemnification The Company generally warrants that its software will perform in accordance with its standard documentation. Under the Company’s standard warranty, should a software product not perform as specified in the documentation within the warranty period, the Company will repair or replace the software or refund the license fee paid. To date, the Company has not incurred any incremental costs related to warranty obligations for its software. The Company’s product license and on-demand agreements typically include a limited indemnification provision for claims by third parties relating to the Company’s intellectual property.

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share Basic net loss per share is calculated by dividing net loss for the period by the weighted average common shares outstanding during the period. Diluted net loss per share is calculated by dividing the net loss for the period by the weighted average common shares outstanding, adjusted for all dilutive potential common shares, which includes shares issuable for the period of time the Company's 4.75% Convertible Senior Notes ("Convertible Notes") were outstanding, the exercise of outstanding common stock options, the release of restricted stock units, and purchases of shares pursuant to the Company's employee stock purchase plan ("ESPP"), to the extent these shares are dilutive. For the three and nine months ended September 30, 2015 and 2014 , the diluted net loss per share calculation was the same as the basic net loss per share calculation as all potential common shares were anti-dilutive. Diluted net loss per share does not include the effect of the following potential weighted average common shares because to do so would be anti-dilutive for the periods presented (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Restricted Stock Units 3,120 2,526 2,803 2,340 Stock Options 806 1,557 945 1,745 ESPP Shares 13 18 4 6 Convertible Notes — — — 1,108 Total 3,939 4,101 3,752 5,199 The weighted average exercise price of stock options excluded for the three and nine months ended September 30, 2015 was $ 6.35 and $ 6.12 , respectively, and for the three and nine months ended September 30, 2014 was $ 5.51 and $ 5.39 , respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-based Compensation	Stock-based Compensation Expense Summary Stock-based compensation expense is measured based on the grant-date fair value of the stock-based awards. The Company recognizes stock-based compensation expense, for the portion of the awards that are ultimately expected to vest, on a ratable basis, over the requisite service period for those awards with graded vesting and service conditions. The table below sets forth a summary of stock-based compensation expense for the three and nine months ended September 30, 2015 and 2014 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Stock Options $ 147 $ 200 $ 464 $ 613 Restricted Stock Units Performance-based Awards 986 440 2,370 1,267 Service-based Awards 2,651 2,064 10,379 5,354 ESPP Shares 231 288 711 682 Total stock-based compensation $ 4,015 $ 2,992 $ 13,924 $ 7,916 As of September 30, 2015 , there were $ 0.9 million , $7.2 million , $ 17.9 million and $ 0.8 million of total unrecognized compensation expense related to stock options, performance-based awards, service-based awards and ESPP shares, respectively. The expenses related to stock options, performance-based awards, service-based awards and ESPP shares are expected to be recognized over a weighted average period of 1.8 years, 2.1 years, 2.1 years and 0.6 years, respectively. The table below sets forth the functional classification of stock-based compensation expense for the three and nine months ended September 30, 2015 and 2014 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Cost of recurring revenue $ 269 $ 226 $ 806 $ 600 Cost of services and other revenue 277 265 856 735 Sales and marketing 1,316 925 3,931 2,327 Research and development 745 481 2,192 1,393 General and administrative 1,408 1,095 6,139 2,861 Total stock-based compensation $ 4,015 $ 2,992 $ 13,924 $ 7,916 Performance-based Awards The Company includes performance-based award activity with restricted stock units. During the nine months ended September 30, 2015 , the Company granted performance awards with vesting contingent on annual SaaS revenue growth at a specified level over the three-year period beginning July 1, 2015 through June 30, 2018. During the nine months ended September 30, 2014 , the Company granted performance awards with vesting contingent on absolute SaaS revenue growth over the three-year period from 2014 through 2016, and the Company’s relative total stockholder return over the three-year period from 2014 through 2016 versus an index of 17 SaaS companies. Determination of Fair Value The fair value of service-based awards is estimated based on the market value of the Company’s stock on the date of grant. A portion of the performance awards granted during 2014 are based on relative stockholder return and therefore, are subject to a market condition. As a result, the fair value of performance awards is calculated using a Monte Carlo simulation model that estimates the distribution of the potential outcomes of the grants of performance awards based on simulated future index of the peer companies. The fair value of each stock option is estimated on the date of grant using the Black-Scholes valuation model. No stock options were granted during the nine months ended September 30, 2015 and September 30, 2014 . The fair value of each ESPP share is estimated on the enrollment date of the offering period using the Black-Scholes valuation model and the assumptions noted in the following table: Nine Months Ended September 30, 2015 2014 Employee Stock Purchase Plan Expected life (in years) 0.50 to 1.00 0.50 to 1.00 Risk-free interest rate 0.25% to 0.38% 0.05% to 0.12% Volatility 38.7% to 39.3% 47% to 50% Dividend yield None None

Segment Reporting [Abstract]
Segment, Geographic and Customer Information	Segment, Geographic and Customer Information The accounting principles guiding disclosures about segments of an enterprise and related information establish standards for the reporting by business enterprises of information about operating segments, products and services, geographic areas, and major customers. The method of determining which information is reported is based on the way that management organizes the operating segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision maker is considered to be the Company’s chief executive officer ("CEO"). The CEO reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. By this definition, the Company operates in one business segment, which is the development, marketing and sale of sales and marketing effectiveness cloud software and related services. The following table summarizes revenue for the three and nine months ended September 30, 2015 and 2014 by geographic areas (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 United States $ 34,342 $ 26,352 $ 96,499 $ 76,845 EMEA 4,570 4,098 13,031 10,845 Asia Pacific 2,389 2,551 7,360 5,793 Other 3,643 1,999 9,413 5,009 $ 44,944 $ 35,000 $ 126,303 $ 98,492 Substantially all of the Company’s long-lived assets are located in the United States and United Kingdom. Long-lived assets located outside the United States and United Kingdom are immaterial. During the three and nine months ended September 30, 2015 and 2014 , no customer accounted for more than 10% of total revenue.

Basis of Presentation and Summary of Accounting Policies	Basis of Presentation and Summary of Accounting Policies All amounts included herein related to these unaudited condensed consolidated financial statements as of September 30, 2015 and the three and nine months ended September 30, 2015 and 2014 are unaudited and should be read in conjunction with the audited consolidated financial statements and the notes thereto included in Callidus Software Inc.'s ("Company") Annual Report on Form 10-K for the year ended December 31, 2014 . Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to the Securities and Exchange Commission ("SEC") rules and regulations regarding interim financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all necessary adjustments for the fair presentation of the Company’s financial position, results of operations and cash flows. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the full fiscal year ending December 31, 2015. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, which include wholly-owned subsidiaries in Australia, Canada, Germany, Hong Kong, India, Japan, Malaysia, Mexico, New Zealand, Serbia, Singapore, and the United Kingdom. All intercompany transactions and balances have been eliminated upon consolidation.
Use of Estimates	Use of Estimates Preparation of the unaudited condensed consolidated financial statements in conformity with GAAP and the rules and regulations of the SEC requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, the reported amounts of revenue and expenses during the reporting period and the accompanying notes. Estimates are used for, but not limited to, uncertain tax liabilities, allowances for doubtful accounts, the useful lives of fixed assets and intangible assets, goodwill and intangible asset impairments, stock-based compensation forfeiture rates, accrued liabilities, the allocation of the value of purchase consideration for business acquisitions, and other contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates such estimates and assumptions on an ongoing basis for continued reasonableness, using historical experience and other factors, including the current economic environment. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such evaluation. Illiquid credit markets, volatile equity and foreign currency markets and fluctuations in information technology spending by prospective customers can increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates. Changes in those estimates, if any, resulting from continuing changes in the economic environment, will be reflected in the condensed consolidated financial statements in future periods.
Revenue Recognition	Revenue Recognition The Company generates revenue by providing software applications as a service ("SaaS") through an on-demand subscription, on-premise perpetual and term licenses and related software maintenance, and professional services. Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. Recurring Revenue. Recurring revenue, which includes software-as-a-service revenue and maintenance revenue, is recognized ratably over the stated contractual period. SaaS revenue consists of subscription fees from customers accessing our cloud-based service offerings. Maintenance revenue consists of fees from customers purchasing support for on-premise solutions. The Company also recognizes revenue associated with customers using its products in excess of contracted usage ("Overages"). Overages are primarily attributed to SaaS products and such Overages are recorded in SaaS revenue. Revenue related to Overages was immaterial during the three and nine months ended in September 30, 2015 and September 30, 2014 . Service and License Revenue. Service and license revenue primarily consist of training, integration and configuration services. Generally, the Company's professional services arrangements are on a time-and-materials basis. Time and material services are recognized as the services are rendered based on inputs to the project, such as billable hours incurred. For fixed-fee professional service arrangements, the Company recognizes revenue under the proportional performance method of accounting and estimates the proportional performance on a monthly basis, utilizing hours incurred to date as a percentage of total estimated hours to complete the project. If the Company does not have a sufficient basis to measure progress toward completion, revenue is recognized upon completion. Service and license revenue also includes revenue from perpetual licenses, which is recognized upon delivery of the product, using the residual method, assuming all the other conditions for revenue recognition have been met. In a limited number of arrangements with non-standard acceptance criteria, the Company defers the revenue until the acceptance criteria is satisfied. Reimbursements, including those related to travel and out-of-pocket expenses, are included in services and license revenue, and an equivalent amount of reimbursable expenses is included in cost of services and license revenue. In general, recurring revenue agreements are entered into for 12 to 36 months, and the professional services are performed within nine months of entering into a contract with the customer, depending on the size of integration. SaaS agreements provide specified service level commitments, excluding scheduled maintenance. The failure to meet this level of service availability may require the Company to credit qualifying customers a portion of their subscription and support fees. Based on the Company's historical experience meeting its service level commitments, the Company does not currently have any liabilities on its balance sheet for these commitments. The Company recognizes revenue when all of the following conditions are met: • Persuasive evidence of an arrangement exists; • Delivery has occurred or services have been rendered; • The fees are fixed or determinable; and • Collection of the fees is reasonably assured. If the Company determines that any one of the four criteria is not met, it will defer recognition of revenue until all the criteria are met. Multiple-deliverable arrangements with on-demand subscription. For on-demand subscription agreements with multiple-deliverables, the Company evaluates each element to determine whether it represents a separate unit of accounting. The Company determines the best estimated selling price of each deliverable in an arrangement based on a selling price hierarchy of methods contained in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2009-13, Revenue Recognition (Accounting Standards Codification (“ASC”) Topic 605)- Multiple-Deliverable Revenue Arrangements. The best estimated selling price for a deliverable is based on its vendor-specific objective evidence (“VSOE”), if available, third-party evidence (“TPE”), if VSOE is not available, or estimated selling price (“ESP”), if neither VSOE nor TPE is available. Total arrangement fees are allocated to each element using the relative selling price method. The Company has currently established VSOE for most deliverables, except for fixed fee service arrangements and on-premise software licenses. The Company considered all of the following factors to establish the ESP for fixed fee service arrangements when sold with its on-demand services: the weighted average actual sales prices of professional services sold on a stand-alone basis for on-demand services; average billing rates for fixed fee service agreements when sold with on-demand services, cost plus a reasonable mark-up and other factors such as gross margin objectives, pricing practices and growth strategy. The Company is currently using cost plus a reasonable mark-up to establish ESP for fixed fee service arrangements. Multiple-deliverable arrangements with on-premise license. For arrangements with multiple-deliverables, including license, professional services and maintenance, the Company recognizes license revenue using the residual method of accounting pursuant to the requirements of the guidance contained in ASC 985-605, Software Revenue Recognition . Under the residual method, revenue is recognized when VSOE for fair value exists for all of the undelivered elements in the arrangement, but does not exist for one or more of the delivered elements in the arrangement. If evidence of fair value cannot be established for the undelivered elements, all of the revenue is deferred until evidence of fair value can be established, or until the items for which evidence of fair value cannot be established are delivered. For maintenance and certain professional services, the Company has established VSOE as a high number of stand-alone sales of this deliverable have been priced within a reasonably narrow range. The Company's revenue arrangements do not include a general right of return relative to the delivered products. For the Company's term-based licenses, if the only undelivered element is maintenance, the entire amount of revenue is recognized over the maintenance period, because the Company does not sell maintenance separately. Sales and other taxes collected from customers to be remitted to government authorities are excluded from revenue.
Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09) "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 may also impact how the Company accounts for certain direct costs associated with its revenues. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted one year earlier. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company has not elected a transition method and is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on the condensed consolidated financial statements and does not plan to early adopt this standard.
