| Basis of Presentation and Significant Accounting Policies [Text Block] | NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Basis of Presentation Net Element, Inc. (“We”, “us”, “our” or the “Company”) is a financial technology-driven group specializing in mobile payments and other transactional services in emerging countries and in the United States. We have three reportable segments: (i) North America Transaction Solutions for electronic commerce, (ii) Mobile Solutions which primarily serves the Russian Federation and Commonwealth of Independent States (“CIS”) and (iii) Online Solutions. We are differentiated by our proprietary technology which enables us to provide a broad suite of payment products, end-to-end transaction processing services and superior client support. We are able to deliver these services across multiple points of access, or “multi-channel,” including brick and mortar locations, software integration, e-commerce, mobile operator billing, mobile and tablet-based solutions. In the United States, via our U.S. based subsidiaries, we generate revenues from transactional services and other payment technologies for small and medium-sized businesses. Through TOT Group Russia and Net Element Russia, we provide transactional services, mobile payment transactions, online payment transactions and other payment technologies in emerging countries in the Russian Federation, CIS, Europe and Asia. Our transactional services business enables merchants to accept credit cards as well as other forms of payment, including debit cards, checks, gift cards, loyalty programs and alternative payment methods in traditional card-present or swipe transactions, as well as card-not-present transactions, such as those conducted over the phone or through the Internet or a mobile device. We market and sell our services through both independent sales groups (“ISGs”), which are non-employee, external sales organizations and other third-party resellers of our products and services, and directly to merchants through electronic media, telemarketing and other programs, including utilizing partnerships with other companies that market products and services to local and international merchants. We have agreements with several banks that sponsor us for membership in the Visa, MasterCard, American Express and Discover card associations and settle card transactions for our merchants. The principal Sponsoring Bank Our Mobile Solutions business, Digital Provider, LLC (f/k/a Tot Money, LLC) (“Digital Provider”) provides carrier-integrated mobile payments solutions. Our relationships with mobile operators give us substantial geographic coverage, a strong capacity for innovation in mobile payments and messaging, and the ability to offer our clients in-app, premium SMS, wap click, one click and other carrier billing services. We also market our own branded content as a separate line of business for our mobile commerce business. PayOnline provides flexible high-tech payment solutions to companies doing business on the Internet or in the mobile environment. PayOnline specializes in integration and customization of payment solutions for websites and mobile apps. In particular, PayOnline arranges payment on the website of any commercial organization, which increases the convenience of using the website and helps maximize the number of successful transactions. In addition, PayOnline is focused on providing online and mobile payment acceptance services to the travel industry through direct integration with leading Global Distribution Systems, which includes Amadeus® and Sabre®. Key regions of PayOnline are the CIS, Eastern Europe, Central Asia, Western Europe, North America and Asia major sub regions. PayOnline offices are located in Russia, Kazakhstan and in the Republic of Cyprus. We included the results of PayOnline starting in May 20, 2015. Aptito is a proprietary, next-generation, cloud-based payments platform for the hospitality industry, which creates an online consumer experience in offline commerce environments via tablet, mobile and all other cloud-connected devices. Aptito’s easy to use point-of-sale (“POS”) system makes things easier by providing comprehensive solution to the hospitality industry to help streamline management and operations. Orders placed tableside by customers directly speed up the ordering process and improve overall efficiency. Aptito's mobile POS system provides portability to the staff while performing all the same functions as a traditional POS system, and more. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of expenses for the period presented. Actual results could differ from those estimates. Significant estimates include (i) the valuation of acquired merchant portfolios, (ii) the collectability of accounts receivable (iii) the recoverability of indeterminate-lived assets, (iv) the remaining useful lives of long-lived assets, and (v) the sufficiency of merchant, aggregator, legal, and other reserves. On an ongoing basis, we evaluate the sufficiency and accuracy of our estimates. Actual results could differ from those estimates. Certain reclassifications have been made to the comparative period amounts to conform to our current period presentation. These reclassifications had no impact on previously presented financial condition or results of operations. We maintain our U.S. dollar-denominated cash in several non-interest bearing bank deposit accounts. All U.S. non-interest bearing transaction accounts are insured up to a maximum of $ 250,000 We maintain $ 498,308 922,062 Accounts receivable are stated net of allowance for doubtful accounts. We estimate an allowance based on experience with our service providers and judgment as to the likelihood of their ultimate payment. We also consider collection experience and make estimates regarding collectability based on payout trends of the customers. In Russia, the service providers are subsidiaries of large telecommunication companies and we do not reserve for these receivables given their financial backing and our historical experience with such companies. The allowance for doubtful accounts was $ 603,031 103,031 We maintain an inventory of POS terminals which we use to service both merchants and independent sales agents. If the terminals are sold for a fee, we expense the cost of these terminals, plus any setup fees at the time of the sale. Often, we will provide the terminals as an incentive for merchants and independent sales agents to enter into a merchant contracts with us. The term of these contracts have an average length of three years and the cost of the terminal plus any setup fees will be amortized over the contract period. If the merchants early terminate their contract with us, they are obligated to either return the terminal or pay for the terminal. The Company has $ 311,206 345,459 308,582 268,501 126,643 110,182 We depreciate our furniture and equipment over a term of three to ten years. Computers and software are depreciated over terms between two and five years. Leasehold improvements are depreciated over the shorter of the economic life or term of each lease. All of our assets are depreciated on a straight-line basis for financial statement purposes. Expenditures for repairs and maintenance are charged to operating expense as incurred. Expenditures that increase the value or productive capacity of assets are capitalized. At the time of retirements, sales, or other dispositions of property and equipment, the original cost and related accumulated depreciation are removed from the respective accounts, and the gains or losses are presented as other expenses. Included in our intangible assets are merchant portfolios, which represent the net book value of an acquired merchant customer base, and are amortized on a straight-line basis over their respective useful lives, generally three to five years. Merchant portfolios are assessed for impairment if events or circumstances indicate that their respective carrying values are not recoverable from the future anticipated undiscounted net cash flows attributable to such assets. In such cases, the amount of any potential impairment would be measured as the excess, if any, of carrying value over the fair value of such assets. We capitalize direct expenses associated with filing of patents and patent applications and amortize the capitalized intellectual property costs over five years beginning when the patent is approved. Additionally, we capitalize the fair value of intangible assets acquired in business combinations. We perform valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination and allocates the purchase price of each acquired business to its respective net tangible and intangible assets. Acquired intangible assets include: merchant portfolios, trade names, non-compete agreements, customer relationships and technology. We review our long-lived assets for impairment whenever events or changes indicate that the carrying amount of an asset or group of assets may not be recoverable. During the twelve months ended December 31, 2016 and 2015, we did not recognize any charges for impairment of goodwill or intangible assets. Capitalized customer acquisition costs consist of up-front cash payments made to Independent Sales Groups (“ISG’s”) for the establishment of new merchant relationships. Capitalized customer acquisition costs represent incremental, direct customer acquisition costs that are recoverable through gross margins associated with merchant contracts. The up-front cash payment to the ISG is based on the estimated gross margin for the first year of the merchant contract. The deferred customer acquisition cost asset is recorded at the time of payment and the capitalized acquisition costs are primarily amortized on a straight-line basis over a period of three years. Management evaluates the capitalized customer acquisition cost for impairment at each balance sheet date by comparing, on a pooled basis by vintage month of origination, the expected future net undiscounted cash flows from underlying merchant relationships to the carrying amount of capitalized customer acquisition costs. If the estimated future net cash flows are lower than the recorded carrying amount, indicating an impairment of the carrying value of the capitalized customer acquisition costs, the impairment loss is charged to operations. During the years ended December 31, 2016 and 2015, we recorded $ 1,319,820 878,085 670,543 356,757 1,697,337 1,048,060 We report commission payments as a cost of revenues in the accompanying consolidated statement of operations and comprehensive loss. We pay agent commissions to ISGs and independent sales agents based on the processing volume of the merchants enrolled. The commission payments are based on varying percentages of the volume processed by us on behalf of the merchants. Percentages vary based on the program type and transaction volume of each merchant. We report commission payments as a cost of revenues in the accompanying consolidated statement of operations and comprehensive loss. At December 31, 2016 and 2015 the residual commissions payable to ISGs and independent sales agents were $ 1,347,352 1,205,751 We pay agent commission on annual fees between January and April of each year. We amortize the annual fees paid in equal monthly amounts from date of payment to end of year. We pay our agent commissions for annual fees in advance of recognizing the associated revenue. We deferred $ 863,604 483,090 Convertible securities containing detachable warrants where the conversion price of the security and/or the exercise price of the warrants are affected by the current market price of our common stock are accounted for as derivative financial instruments when the exercise and conversion prices are not considered to be indexed to our stock. For such issuances of convertible securities with detachable warrants, we initially record both the warrant and the beneficial conversion feature (“BCF”) at fair value, using option pricing models commonly used by the financial services industry (Black-Scholes-Merton options pricing model) using inputs generally observable in the financial services industry. These derivative financial instruments are marked-to-market each reporting period, with unrealized changes in value reflected in earnings as a gain or loss on change in fair value and settlement of beneficial conversion derivative. For discounts arising from issuances of instruments embedded in a debt security, the discount is presented on the consolidated balance sheets as a discount to the principal amount of the related note payable. For discounts arising from issuances of instruments embedded in an equity security, the discount is presented as a reduction to additional paid-in-capital. The resulting discounts arising from the initial recording of the warrants and BCF are amortized over the term of the host security. The classification of the amortization is based on the nature of the host instrument. In this respect, amortization of discounts associated with debt issuances are classified as interest expense, whereas amortization of discounts associated with preferred stock issuances are classified as preferred stock dividends. At the time a warrant or BCF is exercised or cancelled, the fair value of the derivative financial instrument at the time of exercise/cancellation is calculated, and a realized gain or loss on conversion is determined and reported as a gain or loss on change in fair value and settlement of beneficial conversion derivative on the Statement of Operations and Comprehensive Loss. Our financial instruments consist primarily of cash, accounts receivables, merchant portfolios, notes receivable, trade payables and debt instruments. The carrying values of cash and cash equivalents, accounts receivable and trade payables are considered to be representative of their respective fair values due to the short-term nature of these instruments. The carrying amount of the long-term debt of $ 4.6 We measure certain nonfinancial assets and liabilities at fair value on a nonrecurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. We use a three-level fair value hierarchy to prioritize the inputs used to measure fair value and maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1 Quoted market prices in active markets for identical assets or liabilities as of the reporting date Level 2 Observable market based inputs or unobservable inputs that are corroborated by market data Level 3 Unobservable inputs that are not corroborated by market data These non-financial assets and liabilities include intangible assets and liabilities acquired in a business combination as well as impairment calculations, when necessary. The fair value of the assets acquired and liabilities assumed in connection with the PayOnline acquisition, as discussed in Note 4, were measured at fair value by us at the acquisition date. The fair values of our merchant portfolios are primarily based on Level 3 inputs and are generally estimated based upon independent appraisals that include discounted cash flow analyses based on our most recent cash flow projections, and, for years beyond the projection period, estimates based on assumed growth rates. Assumptions are also made regarding appropriate discount rates, perpetual growth rates, and capital expenditures, among others. In certain circumstances, the discounted cash flow analyses are corroborated by a market-based approach that utilizes comparable company public trading values, and, where available, values observed in private market transactions. The inputs used by management for the fair value measurements include significant unobservable inputs, and therefore, the fair value measurements employed are classified as Level 3. The goodwill impairment was primarily based on observable inputs using company specific information and is classified as Level 3. See Note 11 for full concentration disclosure. We are subject to exchange rate risk in our foreign operations in Russia, the functional currency of which is Russian Ruble, where we generate service fee revenues and interest income and incurs product development, engineering, website development, and general and administrative costs and expenses. The Russian engineering operations pay a majority of their operating expenses in their local currencies, exposing us to exchange rate risk. We do not engage in any currency hedging activities. We recognize revenue when the following four basic criteria have been met: (1) persuasive evidence of a sales arrangement exists; (2) performance of services has occurred, (3) the sales price is fixed or determinable, and (4) collectability is reasonably assured. We consider persuasive evidence of a sales arrangement to be the receipt of a billable transaction from aggregators, signed contract or the processing of a credit card transaction. Collectability is assessed based on a number of factors, including transaction history with the customer and the credit worthiness of the customer. If it is determined that the collection is not reasonably assured, revenue is not recognized until collection becomes reasonably assured, which is generally upon receipt of cash. We record cash received in advance of revenue recognition as deferred revenue. Our revenues for the years ended December 31, 2016 and 2015 are principally derived from the following sources: Transactional Processing Fees: Our transactional processing companies derive revenues primarily from the electronic processing of services including: credit, debit, electronic benefits transfer and alternative payment methods card processing authorized and captured through proprietary and third party networks, electronic gift certificate processing, and equipment sales. These revenues are recorded as bankcard and other processing transactions when processed. In addition to generating service fees, Aptito earns monthly license fees for use of its platform. Typically, fees charged to merchants for these processing services are based on a variable percentage of the dollar amount of each transaction and in some instances, additional fees are charged for each transaction. Merchant customers also may be charged miscellaneous fees, including statement fees, annual fees, monthly minimum fees, fees for handling chargebacks, gateway fees, and fees for other miscellaneous services. Generally, we (i) are the primary obligor in our arrangements with our merchant customers, (ii) have latitude in establishing the price of our services, (iii) have the ability to change the product and perform parts of the services, (iv) have discretion in supplier selection, (v) have latitude in determining the product and service specifications to meet the needs of our merchant customers, and (vi) assume credit risk. In such cases, we report revenues as gross of fees deducted by our sponsoring member banks, as well as fees deducted from card-issuing member banks and card associations (Visa® and MasterCard®) on behalf of our sponsoring member banks for interchange and assessments. These fees charged by the card associations to process the credit card transactions are recorded separately as cost of revenue and interchange fees in the accompanying condensed consolidated statement of operations and comprehensive loss. Service Fees: Service fees are generated primarily from mobile payment processing services provided to third party content aggregators by Digital Provider. Service fees for services provided for content providers were recorded net of mobile operator fees during 2014 and the first half of 2015. In July of 2015, TOT Money began to offer its branded content to customers and changed its name to “Digital Provider”. Digital Provider’s revenues for the access of branded content are recorded at the amounts charged to the mobile subscriber. A corresponding charge to cost of sales for mobile operator and content fees is recorded for branded content. Revenues for access to branded content are recorded on the income statement as branded content revenues. Mobile payment processing revenues for third party content providers continue to be accounted for as service fees and presented net of aggregator and mobile operator payments on the consolidated financial statements as these revenues are considered to be agency fees. Cost of revenues for Digital Provider is comprised primarily of mobile operator fees, content provider fees and fees for short numbers paid to mobile operators. Additionally, penalties and penalty recoveries are recorded as cost of sales. Service revenues for mobile payment processing services are presented net as these revenues are considered to be agency fees. Subscription revenues for our branded content are recognized when a content subscriber initiates the purchase of our access to content using WAP-click, Internet-click, or a SMS-to-short number registered to us. Digital Provider’s subscription revenues are recorded at the amounts charged to the third party customer. Cost of revenues for Digital Provider branded content includes fees due to mobile operators and marketing partners, as well as short number fees. Cost of revenues for TOT Payments, Aptito and PayOnline is comprised primarily of processing fees paid to third parties attributable to providing transaction processing and service fees for POS system usage by our merchant customers. Interchange fees and cost of services are recognized as incurred, which generally occurs in the same period in which the corresponding revenue is recognized. Interchange fees are set by the card networks, and are paid to the card-issuing bank. Interchange fees are calculated as a percentage of the dollar volume processed plus a per transaction fee. We also pay Visa® and MasterCard® network dues. We have multiple element arrangements that include bundled transactions with merchants encompassing annual PCI (payment card industry) fees, annual membership fees, and monthly processing fees. We adopted Accounting Standard Update No 2009-13, “MultipleDeliverable Revenue Arrangements” (ASU 2009-13). ASU 2009-13 requires the use of the relative selling price method of allocating total consideration to units of accounting in a multiple element arrangement and eliminates the residual method. This accounting principle requires an entity to allocate revenue in an arrangement using estimated selling price deliverables if it does not have vendor specific objective evidence (VSOE) or third party evidence (TPE) of selling price. VSOE is the price charged when the same or similar product or service is sold separately. We define VSOE as a median price of recent stand-alone transactions that are priced within a narrow range. TPE is determined based on the prices charged by our competitors for a similar deliverable when sold separately. We evaluate each deliverable in its arrangements to determine whether it represents a separate unit of accounting. A deliverable constitutes a separate unit of accounting when it has stand-alone value to our customers. Our products (i.e., terminals) and services qualify as separate units of accounting under ASU 2009-13. Our payment processing division derives revenues primarily from the electronic processing of services including credit, debit and electronic benefits transfer card processing authorized and captured through third party networks, check conversion and guarantee, electronic gift certificate processing, and equipment leasing and sales. These revenues are recorded as bankcard and other processing transactions when processed. Typically, fees charged to merchants for these processing services are based on a variable percentage of the dollar amount of each transaction and in some instances, additional fees are charged for each transaction. Merchant customers may also be charged miscellaneous fees, including statement fees, annual fees, monthly minimum fees, fees for handling chargebacks, gateway fees, and fees for other miscellaneous services. The fair value for annual fees is based on the annual contract renewal price and is deemed to represent stand-alone selling price based upon VSOE. The fair value for processing is based on prices charged by our competitors for similar deliverables when sold separately and is deemed to represent stand-alone selling price based upon TPE. Deferred revenue represents primarily amounts received in advance for annual fee billings and are recognized on a pro rata basis over the service period. Generally, we (i) are the primary obligor in its arrangements with its merchant customers, (ii) have latitude in establishing the price of its services, (iii) have the ability to change the product and perform parts of the services, (iv) have discretion in supplier selection, (v) have latitude in determining the product and service specifications to meet the needs of its merchant customers, and (vi) assume credit risk. In such cases, we report revenues as gross of fees deducted by its sponsoring member banks, as well as fees deducted from card-issuing member banks and card associations (Visa/MasterCard) on behalf of its sponsoring member banks for interchange and assessments. These fees charged by the card associations to process the credit card transactions are recorded separately as cost of sales and interchange fees in the accompanying consolidated statement of operations. Basic net loss per common share is computed by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents, consisting of shares issuable upon exercise of common stock options or warrants. In periods when losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents because their inclusion would have an anti-dilutive effect. At both December 31, 2015 and 2016, respectively, we had warrants outstanding to purchase 893,890 1,464,369 1,936,099 We review our long-lived assets for impairment whenever events or changes indicate that the carrying amount of an asset or group of assets may not be recoverable. During the year ended December 31, 2016 and 2015, there was no impairment of goodwill and intangible assets. We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We recognize net deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. We account for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. We classify the liability for unrecognized tax benefits as current to the extent we anticipate payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized and recorded as necessary in the provision for income taxes. Our evaluation of uncertain tax positions was performed for the tax years ended December 31, 2012 and forward, the tax years which remain subject to examination at December 31, 2016. Please see Note 16 for discussion of our uncertain tax positions. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition” and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, which defers by one year the effective date of ASU 2014-09. Accordingly, this guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted for interim and annual periods beginning after December 15, 2016. We are evaluating the effects that the adoption of ASU 2014-9 will have on our consolidated financial statements, and do not expect a material impact on our financial position, results of operations or cash flows. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes,” which requires entities to present deferred tax assets and deferred tax liabilities as noncurrent in a classified balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. This ASU is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and early adoption is permitted. We adopted this ASU, which had no impact on our financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, “Leases” which, for operating leases, requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The ASU is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effects that the adoption of ASU 2016-02 will have on our consolidated financial statements, and expect an increase in Assets and Liabilities associated with the recognition of right-of-use office leases. In March 2016, the FASB issued Accounting Standards Update 2016-08 Revenue from Contracts with Customers (Topic 606) to clarify implementation guidance on principal versus agent considerations (for reporting revenue on a gross or net basis). The ASU is an amendment to Topic 606, clarifies the implementation guidance, and requires an entity to account for revenue as an agent when another entity controls the specified good or service before that good or service is transferred to the customer. This ASU is effective for annual periods beginning after December 15, 2017. We currently are preparing analyses, across all business lines and customers, to determine the effect of the new revenue recognition standard. While our study is not yet complete, we believe that a portion of our revenue recognized for |
