Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2012
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, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. 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, 2011.
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 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 foreign currency transactions of these subsidiaries are included in net income. The Company recognized a foreign exchange loss of $128,000 and a foreign exchange gain of $527,000 for the three months ended September 30, 2012 and 2011, respectively. The Company recognized a foreign exchange loss of $19,000 for the nine months ended September 30, 2012 and a foreign exchange gain of $654,000 for the nine months ended September 30, 2011, which are classified within other income, net in the Unaudited Consolidated Statements of Income.
Processing Expenses	Processing Expenses The Company has recorded $6.9 million of expenses related to sales of equipment within the processing expenses line of the consolidated statements of income for the three and nine months ended September 30, 2012.
Comprehensive Income	Comprehensive Income Comprehensive income is defined as the total of net income and all other changes in equity that result from transactions and other economic events of a reporting period other than transactions with owners. The Company discloses comprehensive income in the Consolidated Statements of Comprehensive Income.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The December 31, 2011 consolidated balance sheet has been recast to reflect adjustments to the provisional opening balance sheet amounts as discussed further in Note 5.
Adoption of New Accounting Standards	Adoption of New Accounting Standards Fair Value Measurement and Disclosure Requirements In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS,” which amends Accounting Standards Codification (“ASC”) 820, “Fair Value Measurement” to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and IFRS. The amendments in this update explain how to measure fair value. They do not require additional fair value measurements and are not intended to establish valuation standards or affect valuation practices outside of financial reporting. The amendments were effective for and adopted by the Company on January 1, 2012 and are required to be applied prospectively. Since ASU 2011-04 is a disclosure-only standard, the Company’s adoption of this ASU did not affect the Company’s results of operations, financial condition, or cash flows. Other Comprehensive Income Reclassifications In December 2011, the FASB issued ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05,” which supersedes certain pending paragraphs in ASU 2011-05. ASU 2011-12 defers the requirement of ASU 2011-05 requiring entities to present reclassification adjustments by component in both the statement where net income is presented and the statement where other comprehensive income is presented for both interim and annual financial statements. ASU 2011-12 was effective for and adopted by the Company beginning January 1, 2012. The Company’s adoption of this ASU did not affect the Company’s results of operations, financial condition, or cash flows. Qualitative Impairment Test for Indefinite-Lived Intangibles In July 2012, the FASB issued ASU 2012-02, “Intangibles—Goodwill and Other,” which gives companies the option to first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. The proposed guidance is similar to ASU 2011-08 for goodwill. Companies would consider relevant events and circumstances that may affect the significant inputs used in determining the fair value of an indefinite-lived intangible asset. A company that concludes that it is more likely than not that the fair value of such an asset exceeds its carrying amount would not need to calculate the fair value of the asset in the current year. However, if a company concludes that it is more likely than not that the asset is impaired, it must calculate the fair value of the asset and compare that value with its carrying amount, as is required by current guidance. ASU 2012-02 would be applied prospectively for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The Company’s adoption of this ASU is not expected to affect the Company’s results of operations, financial condition, or cash flows.
