Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Throughout this Current Report on Form 10-Q, the terms “our,” “we,” “us,” and the “Company” refers to FLEETCOR Technologies, Inc. and its subsidiaries. The Company prepared the accompanying unaudited interim consolidated financial statements in accordance with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”). The unaudited interim consolidated financial statements reflect all adjustments considered necessary for fair presentation. These adjustments consist of normal recurring accruals and estimates that impact the carrying value of assets and liabilities. Actual results may differ from these estimates. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.
Use of estimates	Use of estimates The preparation of financial statements in conformity with GAAP 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 date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Future events and their effects cannot be predicted with certainty; accordingly, accounting estimates require the exercise of judgment. These financial statements were prepared using information reasonably available as of March 31, 2020 and through the date of this Report. The accounting estimates used in the preparation of the Company’s consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results may differ from these estimates due to the uncertainty around the magnitude and duration of the COVID-19 pandemic, as well as other factors.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of foreign subsidiaries are translated into U.S. dollars at the rates of exchange in effect at period-end. The related translation adjustments are recorded to accumulated other comprehensive income (loss). Income and expenses are translated at the average monthly rates of exchange in effect during the period. Gains and losses from foreign currency transactions of these subsidiaries are included in net income.
Derivatives	Derivatives The Company uses derivatives to minimize its exposures related to changes in interest rates and facilitate cross-currency corporate payments by writing derivatives to customers. The Company is exposed to the risk of changing interest rates because its borrowings are subject to variable interest rates. In order to mitigate this risk, the Company utilizes derivative instruments. Interest rate swap contracts designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company hedges a portion of its variable rate debt utilizing derivatives designated as cash flow hedges. Changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recorded in other assets or other noncurrent liabilities and offset against accumulated other comprehensive income/loss, net of tax. Derivative fair value changes that are recorded in accumulated other comprehensive income/loss are reclassified to earnings in the same period or periods that the hedged item affects earnings, to the extent the derivative is effective in offsetting the change in cash flows attributable to the hedged risk. The portions of the change in fair value that are either considered ineffective or are excluded from the measure of effectiveness are recognized immediately within earnings. In the Company's cross-border payments business, the majority of revenue is from exchanges of currency at spot rates, which enables customers to make cross-currency payments. In addition, the Company writes foreign currency forward and option contracts for its customers to facilitate future payments. The duration of these derivative contracts at inception is generally less than one year. The Company aggregates its foreign exchange exposures arising from customer contracts, including forwards, options and spot exchanges of currency, as necessary, and economically hedges the net currency risks by entering into offsetting derivatives with established financial institution counterparties. The changes in fair value related to these derivatives are recorded in revenues, net in the Unaudited Consolidated Statements of Income. The Company recognizes all cross currency payments derivatives in "prepaid expenses and other current assets" and "other current liabilities" in the accompanying Consolidated Balance Sheets at their fair value. All cash flows associated with derivatives are included in cash flows from operating activities in the Consolidated Statements of Cash Flows.
Cash, Cash Equivalents, and Restricted Cash	Cash, Cash Equivalents, and Restricted Cash Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of three months or less. Restricted cash represents customer deposits repayable on demand.
Financial Instruments-Credit Losses	Financial Instruments-Credit Losses The Company adopted ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", on January 1, 2020, under which the Current Expected Credit Loss methodology for measurement of credit losses on financial assets measured at amortized cost basis, replaces the previous incurred loss impairment methodology. The Company’s financial assets subject to credit losses are primarily trade receivables. The Company utilizes a combination of aging or loss-rate methods to develop an estimate of current expected credit losses, depending on the nature and risk profile of the underlying asset pool. Expected credit losses are estimated based upon an assessment of risk characteristics, historical payment experience, and the age of outstanding receivables, adjusted for forward-looking economic conditions. The allowances for remaining financial assets measured at amortized cost basis are evaluated based on underlying financial condition, credit history, and current and forecast economic conditions. The estimation process for expected credit losses includes consideration of qualitative and quantitative risk factors associated with the age of asset balances, expected timing of payment, contract terms and conditions, changes in specific customer risk profiles or mix of customers, geographic risk, economic trends and relevant environmental factors.
Revenue	Revenue The Company provides payment solutions to our business, merchant, consumer and payment network customers. Our payment solutions are primarily focused on specific commercial spend categories, including fuel, lodging, tolls, and general corporate payments, as well as gift card solutions (stored value cards and e-cards). The Company provides products that help businesses of all sizes control, simplify and secure payment of various domestic and cross-border payables using specialized payment products. The Company also provides other payment solutions for fleet maintenance, employee benefits and long haul transportation-related services. Revenues from contracts with customers, within the scope of ASC 606, represent approximately 80% of total consolidated revenues, net, for the three months ended March 31, 2020. The Company accounts for remaining revenues comprised of late fees and finance charges, in jurisdictions where permitted under local regulations, primarily in the U.S. and Canada in accordance with ASC 310, "Receivables". Such fees are recognized net of a provision for estimated uncollectible amounts, at the time the fees and finance charges are assessed and services are provided. The Company also writes foreign currency forward and options contracts for its customers to facilitate future payments in foreign currencies, and recognizes revenue in accordance with authoritative fair value and derivatives accounting (ASC 815, "Derivatives").
Spot Trade Offsetting	Spot Trade OffsettingThe Company uses spot trades to facilitate cross-currency corporate payments in its Cambridge business. Timing in the receipt of cash from the customer results in intermediary balances in the receivable from the customer and the payment to the customer's counterparty. In accordance with ASC Subtopic 210-20, "Offsetting," the Company applies offsetting to spot trade assets and liabilities associated with contracts that include master netting agreements, as a right of setoff exists, which the Company believes to be enforceable. As such, the Company has netted the Company's exposure with these customer's counterparties, with the receivables from the customer. The Company recognizes all spot trade assets, net in accounts receivable and all spot trade liabilities, net in accounts payable, each net at the customer level, in its Consolidated Balance Sheets at their fair value.
Adoption of Accounting Standards	Adoption of New Accounting Standards Cloud Computing Arrangements On August 29, 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract", that provides guidance on implementation costs incurred in a cloud computing arrangement (CCA) that is a service contract. The ASU, which was released in response to a consensus reached by the EITF at its June 2018 meeting, aligns the accounting for such costs with the guidance on capitalizing costs associated with developing or obtaining internal-use software. Specifically, the ASU amends ASC 350 to include in its scope implementation costs of a CCA that is a service contract and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in such a CCA. The Company adopted this guidance on January 1, 2020, which did not have a material impact on the Company's results of operations, financial condition, or cash flows. Fair Value Measurement On August 28, 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement", which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. The guidance is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The guidance on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other guidance should be applied retrospectively to all periods presented upon their effective date. The Company adopted this guidance on January 1, 2020, which did not have a material impact on the Company's results of operations, financial condition, or cash flows. Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", which changes how companies measure and recognize credit impairment for many financial assets. The new expected credit loss model will require companies to immediately recognize an estimate of credit losses expected to occur over the remaining life of the financial assets (including trade receivables) that are in the scope of the update. The update also made amendments to the current impairment model for held-to-maturity and available-for-sale debt securities and certain guarantees. The Company adopted this guidance on January 1, 2020, which did not have a material impact on the Company's results of operations, financial condition, or cash flows. The Company has made updates to it policies and internal controls over financial reporting as a result of the adoption. See revisions to Company's policy above. In April 2019, the FASB issued ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments", which clarifies certain aspects of accounting for credit losses, hedging activities, and financial instruments. For clarifications around credit losses, the effective date will be the same as the effective date in ASU 2016-13. For entities that have adopted ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities", ASU 2019-04 is effective the first annual reporting period beginning after the date of issuance of ASU 2019-04 and may be early adopted. The Company adopted this guidance on January 1, 2020, which did not have a material impact on the Company's results of operations, financial condition, or cash flows. The Company has made updates to it policies and internal controls over financial reporting as a result of the adoption. Pending Adoption of Recently Issued Accounting Standard Income Taxes On December 18, 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which removes certain exceptions to the general principles of ASC 740 and simplifies other areas in order to simplify its application. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, with early adoption permitted. The Company's adoption of this ASU is not expected to have a material impact on the results of operations, financial condition, or cash flows.
