Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Throughout this report, the terms “our,” “we,” “us,” and the “Company” refers to FleetCor Technologies, Inc. and its subsidiaries. The Company prepared the accompanying 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 consolidated financial statements reflect all adjustments considered necessary for fair presentation. These adjustments consist primarily of normal recurring accruals and estimates that impact the carrying value of assets and liabilities. Actual results may differ from these estimates. Operating results for the three and nine month periods ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. The unaudited consolidated interim 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, 2013.
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 made directly to accumulated other comprehensive income. Income and expenses are translated at the average monthly rates of exchange in effect during the period. Gains and losses from realized foreign currency transactions of these subsidiaries are included in net income. The Company recognized foreign exchange losses of $0.6 million for the three months ended September 30, 2014 and gains of $0.3 million for the three months ended September 30, 2013. The Company recognized foreign exchange losses of $0.8 million and for the nine months ended September 30, 2014 and foreign exchange gains of $0.1 million for the nine months ended September 30, 2013, which are recorded within other expense, net in the Unaudited Consolidated Statements of Income.
Equity Method Investment	Equity Method Investment The Company applies the equity method of accounting for investments when the Company does not control the investee, but has the ability to exercise significant influence over its operating and finance policies. Equity method investments are recorded at cost, with the allocable portion of the investee’s income or loss reported in earnings, and adjusted for capital contributions to and distributions from the investee. Distributions in excess of equity method earnings, if any, are recognized as a return of investment and recorded as investing cash flows in the unaudited Condensed Consolidated Statements of Cash Flows. The Company reviews its equity investment for impairment whenever events or changes in circumstances indicate that the carrying value of the Company‘s investment may have experienced an other-than-temporary decline in value.
Adoption of New Accounting Standards	Adoption of New Accounting Standards Foreign Currency In March 2013, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2013-05 “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity”, which indicates that the entire amount of a cumulative translation adjustment (“CTA”) related to an entity’s investment in a foreign entity should be released when there has been a sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity, loss of a controlling financial interest in an investment in a foreign entity (i.e., the foreign entity is deconsolidated) or step acquisition for a foreign entity (i.e., when an entity has changed from applying the equity method for an investment in a foreign entity to consolidating the foreign entity). The ASU does not change the requirement to release a pro rata portion of the CTA of the foreign entity into earnings for a partial sale of an equity method investment in a foreign entity. This ASU is effective for the Company for fiscal years and interim periods within those fiscal years beginning on or after December 15, 2013. The Company’s adoption of this ASU did not have a material impact on the Company’s results of operations, financial condition, or cash flows. Unrecognized Tax Benefit When an NOL Exists In July 2013, the FASB issued ASU 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”, which indicates that to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This ASU is effective for the Company for fiscal years and interim periods within those fiscal years beginning on or after December 15, 2013. The Company’s adoption of this ASU did not have a material impact on the Company’s results of operations, financial condition, or cash flows. Revenue Recognition In May 2014, the FASB issued ASC 606, “Revenue from Contracts with Customers”, which amends the guidance in former ASC 605, Revenue Recognition. This ASU is effective for the Company for fiscal years ending after December 15, 2016 and interim periods, with early adoption not permitted. The Company is currently evaluating the impact of the provisions of ASC 606.
Going Concern	Going Concern In August 2013, the FASB issued ASU 2014-15 “Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern”, which requires entities to perform interim and annual assessments of the entity’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements. This ASU is effective for the Company for fiscal years ending after December 15, 2016 and interim periods thereafter, with early adoption permitted. The Company’s adoption of this ASU is not expected to have a material impact on the Company’s results of operations, financial condition, or cash flows, as it is disclosure based.

Disclosure of accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends). This disclosure may also include a detailed description of the policy for determining the amount of equity method losses recognized after an investment has been reduced to zero as a result of previous losses, reasons for not using the equity method when the investor company owns 20 percent or more of the voting stock of the investee's company (including identification of the significant investee), reasons for using the equity method when the ownership percentage is less than 20 percent, and discussion of recognition of equity method losses when an investor's total investment in an investee includes, in addition to an investment in common stock, other investments such as preferred stock and loans to the investee. An entity also may describe how such investments are assessed for impairment.

- Definition

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.
