Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Communications Systems, Inc. (herein collectively referred to as “CSI,” “our,” “we” or the “Company”) is a Minnesota corporation organized in 1969 that has classified its business into two As described in Note 16 of Notes to Financial Statements, on August 2, 2021, the Company and Lantronix, Inc. completed the sale by CSI to Lantronix of all of the issued and outstanding stock of CSI’s wholly owned subsidiary, Transition Networks, Inc., and the entire issued share capital of its wholly owned subsidiary, Transition Networks Europe Limited (collectively with Transition Networks, Inc., the “TN Companies”), pursuant to the securities purchase agreement dated April 28, 2021 (“E&S Sale Transaction”). For purposes of this Form 10-Q, the Company classifies its businesses into the two Financial Statement Presentation The condensed consolidated balance sheet as of June 30, 2021, the related condensed consolidated statements of loss and comprehensive loss, the condensed consolidated statements of changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the periods ended June 30, 2021 and 2020 have been prepared by Company management. In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2021 and 2020 and for the periods then ended have been made. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2020 Annual Report to Shareholders on Form 10-K (“2020 Form 10-K”). The results of operations for the period ended June 30, 2021 are not necessarily indicative of operating results for the entire year. The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates. Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the December 31, 2020 Form 10-K, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference. Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss Accumulated Other Comprehensive Loss Other Foreign Currency Unrealized gain Comprehensive Translation (loss) on securities Loss December 31, 2020 $ (700,000) $ 21,000 $ (679,000) Net current period change 56,000 (7,000) 49,000 June 30, 2021 $ (644,000) $ 14,000 $ (630,000)	NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of business two The Company classifies its businesses into two segments. Non-allocated general and administrative expenses are separately accounted for as “Other” in the Company’s segment reporting. Intersegment revenues are eliminated upon consolidation. Principles of consolidation Use of estimates Cash equivalents 13,092,000 9,424,000 1.00 Investments Inventories Property, plant and equipment 757,000 1,028,000 Goodwill and Other Intangible Assets Goodwill represents the amount by which the purchase prices (including liabilities assumed) of acquired businesses exceed the estimated fair value of the net tangible assets and separately identifiable assets of these businesses. Goodwill and The Company reassesses the value of our reporting units and related goodwill balances annually on April 1 and at other times if events have occurred or circumstances exist that indicate the carrying amount of goodwill may not be recoverable. Recoverability of long-lived assets Warranty The following table presents the changes in the Company’s warranty liability, included in other accrued liabilities in the consolidated balance sheets, for the years ended December 31, 2020 and 2019, which relate to normal product warranties and a five Schedule of warranty Year Ended December 31 2020 2019 Beginning balance $ 513,000 $ 554,000 Amounts charged to expense 59,000 10,000 Actual warranty costs paid (67,000 ) (51,000 ) Ending balance $ 505,000 $ 513,000 Accumulated other comprehensive loss The components of accumulated other comprehensive loss Foreign Unrealized Accumulated December 31, 2018 $ (764,000 ) $ 13,000 $ (751,000 ) Net current period change 55,000 (2,000 ) 53,000 December 31, 2019 $ (709,000 ) $ 11,000 $ (698,000 ) Net current period change 9,000 10,000 19,000 December 31, 2020 $ (700,000 ) $ 21,000 $ (679,000 ) Revenue recognition The Company has determined that the following performance obligations identified in its Services and Support segment are transferred over time: managed services and professional services (time and materials (“T&M”) and fixed price). This segment’s managed services performance obligation is a bundled solution, a series of distinct services that are substantially the same and that have the same pattern of transfer to the customer and are recognized evenly over the term of the contract. T&M professional services arrangements are measured over time with an input method based on hours expended towards satisfying this performance obligation. Fixed price professional service arrangements under a relatively longer-term service will also be measured over time with an input method based on hours expended. The Company has also identified the following performance obligations within its Services and Support segment that are recognized at a point in time which include resale of third-party hardware and software, installation, arranging for another party to transfer services to the customer, and certain professional services. The resale of third-party hardware and software is recognized at a point in time, when the goods are shipped or delivered to the customer’s location, in accordance with the agreed upon shipping terms. Installation services are recognized at a point in time when the services are completed. The service the Company provides to arrange for another party to transfer services to the customer is satisfied at a point in time as the Company has transferred control upon the service first being made available to the customer by the third-party vendor, which are required to be presented on a net basis. Depending on the nature of the service, certain professional services transfer control at a point in time. The Company evaluates these circumstances on a case by case basis to determine if revenue should be recognized over time or at a point in time. See Note 2 for further discussion regarding revenue recognition.

The estimated grant date fair value of each stock-based award is recognized in income over the requisite service period (generally the vesting period). The estimated fair value of each option is calculated using the Black-Scholes option-pricing model. Accqounting standards issued In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This ASU is intended to provide financial statement users with more decision-useful information about expected credit losses and is effective for annual periods and interim periods for those annual periods beginning after December 15, 2022, which for us is the first quarter ending March 31, 2023. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements. Accounting standards adopted In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement.” This new standard requires changes to the disclosure requirements for fair value measurements for certain Level 3 items and specifies that some of the changes must be applied prospectively, while others should be applied retrospectively. This standard is effective for public business entities in fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. the company adopted this standard during 2020 with an immaterial impact to our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes”, which, as part of its Simplification Initiative to reduce the cost and complexity in accounting for income taxes, removes certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company adopted this standard during 2020 with an immaterial impact to our consolidated financial statements.

REVENUE RECOGNITION

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	NOTE 2 – REVENUE RECOGNITION Electronics & Software The Company has determined that the revenue recognition for its Electronics & Software segment occurs upon delivery of the Company’s connectivity infrastructure and data transmission products. To determine when revenue should be recognized, it is important to determine when the transfer of control has occurred. The Company has determined that control transfers for these products upon shipment or delivery to the customer, in accordance with the agreed-upon shipping terms. As such, the timing of revenue recognition occurs at a specific point in time. Services & Support The Company has determined that the following performance obligations identified in its Services & Support segment are transferred over time: managed services and professional services (time and materials (“T&M”) and fixed price) as well as services under maintenance and service contracts. The managed services performance obligation is a bundled solution consisting of a series of distinct services that are substantially the same and that have the same pattern of transfer to the customer and are therefore recognized evenly over the term of the contract. T&M professional services arrangements are recognized over time with an input method based on hours expended towards satisfying the performance obligation. Fixed price professional service arrangements under a relatively longer-term service are also recognized over time with an input method based on hours expended. Maintenance and service contracts are recognized evenly over the life of the contract. The Company has also identified the following performance obligations within its Services & Support segment that are recognized at a point in time which include resale of third-party hardware and software, installation, arranging for another party to transfer services to the customer, and certain professional services. The resale of third-party hardware and software is recognized at a point in time, when the goods are shipped or delivered to the customer’s location, in accordance with the shipping terms. Installation services are recognized at a point in time when the services are completed. The service the Company provides to arrange for another party to transfer services to the customer is satisfied at a point in time after the Company has transferred control when the service is first available to the customer by the third-party vendor. The Company reports revenue from these third-party services on a net basis in its financial statements. Depending on the nature of the service, certain professional services transfer control at a point in time. The Company evaluates these circumstances on a case by case basis to determine if revenue should be recognized over time or at a point in time. Disaggregation of revenue Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that best reflects the consideration we expect to receive in exchange for those goods or services. In accordance with ASC 606-10-50-5, the following tables present how we disaggregate our revenues, which is different for each segment. For the Electronics & Software segment, we analyze revenue by region and product group, which is as follows for the three and six months ended June 30, 2021 and 2020: Schedule of Disaggregation of Revenues Electronics & Software Sales by Region Three Months Ended June 30 Six Months Ended June 30 2021 2020 2021 2020 North America $ 7,721,000 $ 6,898,000 $ 14,921,000 $ 14,346,000 International 1,586,000 1,389,000 2,750,000 2,477,000 $ 9,307,000 $ 8,287,000 $ 17,671,000 $ 16,823,000 Electronics & Software Sales by Product Group Three Months Ended June 30 Six Months Ended June 30 2021 2020 2021 2020 Intelligent edge solutions $ 3,779,000 $ 3,023,000 $ 7,492,000 $ 6,377,000 Traditional products 5,528,000 5,264,000 10,179,000 10,446,000 $ 9,307,000 $ 8,287,000 $ 17,671,000 $ 16,823,000 For the Services & Support segment, we analyze revenue by customer group and type, which is as follows for the three and six months ended June 30, 2021 and 2020: Services & Support Revenue by Customer Group Three Months Ended June 30 Six Months Ended June 30 2021 2020 2021 2020 Financial $ 399,000 $ 103,000 $ 824,000 $ 196,000 Healthcare 245,000 240,000 498,000 430,000 Education 85,000 626,000 149,000 719,000 Other commercial clients 960,000 371,000 2,013,000 621,000 CSI IT operations 144,000 185,000 288,000 386,000 $ 1,833,000 $ 1,525,000 $ 3,772,000 $ 2,352,000 Services & Support Revenue by Type Three Months Ended June 30 Six Months Ended June 30 2021 2020 2021 2020 Project & product revenue $ 245,000 $ 746,000 $ 630,000 $ 886,000 Services & support revenue 1,588,000 779,000 3,142,000 1,466,000 $ 1,833,000 $ 1,525,000 $ 3,772,000 $ 2,352,000	NOTE 2 – REVENUE RECOGNITION In accordance with Accounting Standards Codification (“ASC”) 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration that the Company expects to receive in exchange for these goods or services. Electronics & Software The Company has determined that the revenue recognition for its Electronics & Software segment occurs upon delivery of the Company’s connectivity infrastructure and data transmission products. To determine when revenue should be recognized, it is important to determine when the transfer of control has occurred. The Company has determined that control transfers for these products upon shipment or delivery to the customer, in accordance with the agreed upon shipping terms. As such, the timing of revenue recognition occurs at a specific point in time. Services & Support The Company has determined that the following performance obligations identified in its Services & Support segment are transferred over time: managed services and professional services (time and materials (“T&M”) and fixed price). The managed services performance obligation is a bundled solution, a series of distinct services that are substantially the same and that have the same pattern of transfer to the customer and are recognized evenly over the term of the contract. T&M professional services arrangements are measured over time with an input method based on hours expended towards satisfying this performance obligation. Fixed price professional service arrangements under a relatively longer-term service will also be measured over time with an input method based on hours expended. The Company has also identified the following performance obligations within its Services & Support segment that are recognized at a point in time which include resale of third-party hardware and software, installation, arranging for another party to transfer services to the customer, and certain professional services. The resale of third-party hardware and software is recognized at a point in time, when the goods are shipped or delivered to the customer’s location, in accordance with the agreed upon shipping terms. Installation services are recognized at a point in time when the services are completed. The service the Company provides to arrange for another party to transfer services to the customer is satisfied at a point in time as the Company has transferred control upon the service first being made available to the customer by the third-party vendor, which are required to be presented on a net basis. Depending on the nature of the service, certain professional services transfer control at a point in time. The Company evaluates these circumstances on a case-by-case basis to determine if revenue should be recognized over time or at a point in time. Significant Judgments To determine the transaction price, the Company estimates the amount of variable consideration at the outset of the contract, depending on the facts and circumstances relative to the contract. The Company may provide credits or incentives to its customers, which are accounted for as either variable consideration or consideration payable to the customer. The Company estimates product returns based on historical return rates. The Company constrains (reduces) the estimates of variable consideration such that it is probable that a significant revenue reversal of previously recognized revenue will not occur throughout the life of the contract. When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal of revenue. The Company will assess if any incentives it offers to its customer is a consideration payable. The Company accounts for consideration payable to a customer as a reduction of the transaction price, and therefore, of revenue. For contracts with more than one performance obligation, the consideration is allocated between separate products and services based on their stand-alone selling prices. Judgment is required to determine standalone selling prices for each distinct performance obligation. The Company generally determines standalone selling prices based on the actual prices charged to customers and has an established range of amounts that fall within stand-alone selling price for its distinct performance obligations. The Company evaluates this range quarterly. Costs to Obtain or Fulfill a Contract The Company evaluates “Other Assets and Deferred Costs” (ASC 340-40), for the accounting for certain costs to obtain and fulfill contracts (or, in some cases, an anticipated contract) with a customer. ASC 340-40 is applicable only to incremental contract costs, those that an entity would not have incurred if the contract had not been obtained, and requires the capitalization of these costs as well as provides guidance on the amortization and impairment considerations. The Company elects the practical expedient and expenses certain costs to obtain contracts when applicable. Within Services & Support, commissions were paid upfront on certain long-term recurring revenue agreements. Total costs to obtain a contract in the years ended December 31, 2020 and 2019 were $ 52,000 0 Transaction Price Allocated to Future Performance Obligations To determine the allocation of the transaction price and amounts allocated to the performance obligations, the Company first determined the standalone selling price for each distinct performance obligation in the contract in order to determine the allocations of the transaction price in proportion to the standalone selling price for each performance obligation in the contract in accordance with ASC 606-10-32-31 and 32-33. Judgment is required to determine standalone selling price for each distinct performance obligation. The Company generally determines standalone selling prices based on the actual prices charged to customers and has an established range of amounts that fall within stand-alone selling price for its distinct performance obligations. The Company evaluates this range quarterly. Practical Expedients and Exemptions The Company adopted various practical expedients and policy elections related to the accounting for significant finance components, sales taxes, shipping and handling, costs to obtain a contract and immaterial promised goods or services. The practical expedient to disclose the unfulfilled performance obligations was not made as they are expected to be fulfilled within one year. Disaggregation of revenue Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that best reflects the consideration we expect to receive in exchange for those goods or services. In accordance with ASC 606-10-50-5, the following tables present how we disaggregate our revenues, which is different for each segment.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 14 – FAIR VALUE MEASUREMENTS The accounting guidance establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date. Level 2 – Observable inputs such as quoted prices for similar instruments and quoted prices in markets that are not active, and inputs that are directly observable or can be corroborated by observable market data. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities. Level 3 – Significant inputs to pricing that have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value of financial instruments.

RECENT ACCOUNTING PRONOUNCEMENTS	NOTE 15 – RECENT ACCOUNTING PRONOUNCEMENTS In June 2016, FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments." The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This ASU is intended to provide financial statement users with more decision-useful information about the expected credit losses and is effective for annual periods and interim periods for those annual periods beginning after December 15, 2022, which for us is the first quarter ending March 31, 2023. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.

In connection with the Merger, CSI intends to pursue dispositions of its existing assets and businesses prior to the closing of the Merger. To the extent these dispositions occur, CSI expects to declare a cash dividend that distributes a portion of the proceeds from these dispositions to its shareholders as of a pre-closing record date. Following the closing, CSI will use commercially reasonable efforts to complete the dispositions of these assets as soon as reasonably practicable (and, in any event, within 18 months of the closing). Proceeds that become available from the dispositions that occur following the closing of the Merger will be distributed pro rata to the legacy shareholders pursuant to the contingent value rights agreement described above. CSI will continue to support these existing business lines as it pursues new owners for these businesses. In connection with the execution of the Merger agreement, the Company announced that CSI and Pineapple Energy were exploring equity financing through a private placement that would close in connection with the closing of Merger, with proceeds to be used by the combined company to finance additional acquisitions and working capital needs of the combined company.

Leases
LEASES	NOTE 3 – LEASES In accordance with ASC Topic 842, the Company recognizes assets and liabilities for the rights and obligations created by leases that extend more than twelve months from the date of the balance sheet. Right of use (“ ROU”) assets represent our right to use an underlying asset for the lease term, while lease liabilities represent our obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the commencement date of a lease based on the present value of lease payments over the lease term. Because the rate implicit in each individual lease is not readily determinable, the Company uses its incremental borrowing rate to determine the present value of the lease payments.

In the opinion of management, all adjustments (which include only normal recurring adjustments, except where noted) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2021 and 2020 and for the periods then ended have been made. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted. We recommend these condensed consolidated financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s December 31, 2020 Annual Report to Shareholders on Form 10-K (“2020 Form 10-K”). The results of operations for the period ended June 30, 2021 are not necessarily indicative of operating results for the entire year. The presentation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates. Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the December 31, 2020 Form 10-K, appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.

Revenue recognition		Revenue recognition The Company has determined that the following performance obligations identified in its Services and Support segment are transferred over time: managed services and professional services (time and materials (“T&M”) and fixed price). This segment’s managed services performance obligation is a bundled solution, a series of distinct services that are substantially the same and that have the same pattern of transfer to the customer and are recognized evenly over the term of the contract. T&M professional services arrangements are measured over time with an input method based on hours expended towards satisfying this performance obligation. Fixed price professional service arrangements under a relatively longer-term service will also be measured over time with an input method based on hours expended. The Company has also identified the following performance obligations within its Services and Support segment that are recognized at a point in time which include resale of third-party hardware and software, installation, arranging for another party to transfer services to the customer, and certain professional services. The resale of third-party hardware and software is recognized at a point in time, when the goods are shipped or delivered to the customer’s location, in accordance with the agreed upon shipping terms. Installation services are recognized at a point in time when the services are completed. The service the Company provides to arrange for another party to transfer services to the customer is satisfied at a point in time as the Company has transferred control upon the service first being made available to the customer by the third-party vendor, which are required to be presented on a net basis. Depending on the nature of the service, certain professional services transfer control at a point in time. The Company evaluates these circumstances on a case by case basis to determine if revenue should be recognized over time or at a point in time. See Note 2 for further discussion regarding revenue recognition.

The estimated grant date fair value of each stock-based award is recognized in income over the requisite service period (generally the vesting period). The estimated fair value of each option is calculated using the Black-Scholes option-pricing model.
Accqounting standards issued		Accqounting standards issued In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments.” The amendments in this update replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. This ASU is intended to provide financial statement users with more decision-useful information about expected credit losses and is effective for annual periods and interim periods for those annual periods beginning after December 15, 2022, which for us is the first quarter ending March 31, 2023. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact of the adoption of ASU 2016-13 on our consolidated financial statements.
Accounting standards adopted		Accounting standards adopted In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement.” This new standard requires changes to the disclosure requirements for fair value measurements for certain Level 3 items and specifies that some of the changes must be applied prospectively, while others should be applied retrospectively. This standard is effective for public business entities in fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. the company adopted this standard during 2020 with an immaterial impact to our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes”, which, as part of its Simplification Initiative to reduce the cost and complexity in accounting for income taxes, removes certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 also amends other aspects of the guidance to help simplify and promote consistent application of GAAP. The guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company adopted this standard during 2020 with an immaterial impact to our consolidated financial statements.
