Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	1. Summary of Significant Accounting Policies 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, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011. 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, 2010. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. Derivative Financial Instruments Derivative financial instruments are generally used to manage certain interest rate risks through the use of interest rate swaps. These instruments, when settled, impact the Company's cash flows from operations. On the date in which the Company enters into a derivative, the derivative is designated as a hedge of the identified exposure. The Company measures effectiveness of its hedging relationships both at hedge inception and on an ongoing basis. Gains and losses on interest rate swaps designated as cash flow hedges, to the extent that the hedge relationship has been effective, are deferred in other comprehensive income and recognized in interest expense over the period in which the Company recognizes interest expense on the related debt instrument. Any ineffectiveness on these instruments is immediately recognized in interest expense in the period that the ineffectiveness occurs. No significant ineffectiveness was recorded on designated hedges in the three and nine month periods ended September 30, 2010, respectively. All interest rate swaps to which the Company was a party matured prior to the beginning of 2011. 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 foreign currency transactions of these subsidiaries are included in net income. The Company recognized foreign exchange gains of $0.53 million and $0.64 million for each of the three months ended September 30, 2011 and 2010. The Company recognized foreign exchange gains of $0.65 million and $0.66 million for the nine months ended September 30, 2011 and September 30, 2010, respectively, which are classified within other income, net in the unaudited Consolidated Statements of Income. Comprehensive Income (Loss) Comprehensive income (loss) 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's accumulated other comprehensive loss includes foreign currency translation losses of $8.6 million and $6.8 million and the unrealized loss on interest rate swaps of $0 and $0.8 million for the nine months ended September 30, 2011 and 2010, respectively. Adoption of New Accounting Standards In January 2010, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2010-06, "Improving Disclosures About Fair Value Measurements," which amends Accounting Standards Codification ("ASC") 820, "Fair Value Measurements and Disclosures," to add new requirements for disclosures about transfers into and out of Levels 1 and 2 of the fair value hierarchy and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements within the fair value hierarchy. This ASU also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. This ASU was effective for the Company beginning January 1, 2010, except for the requirements to provide the Level 3 activity of purchases, sales, issuance, and settlements, if any, which were effective for the Company beginning January 1, 2011. Since ASU 2010-06 is a disclosure-only standard, its adoption had no impact on the Company's results of operations, financial condition, or cash flows. In October 2009, the FASB issued ASU 2009-13, "Multiple Revenue Arrangements - a Consensus of the FASB Emerging Issues Task Force" which supersedes certain guidance in ASC 605-25, "Revenue Recognition-Multiple Element Arrangements," and requires an entity to allocate arrangement consideration to all of its deliverables at the inception of an arrangement based on their relative selling prices (i.e., the relative-selling-price method). The use of the residual method of allocation will no longer be permitted in circumstances in which an entity recognized revenue for an arrangement with multiple deliverables subject to ASC 605-25. ASU 2009-13 also requires additional disclosures. The Company adopted the provisions of ASU 2009-13 beginning on January 1, 2011. Based on the Company's current revenue arrangements, the adoption of ASU 2009-13 did not have a material impact on the Company's financial condition, results of operations, or cash flows. In April 2010, the FASB issued ASU 2010-13, "Compensation-Stock Compensation (Topic 718) — Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the Market in Which the Underlying Equity Security Trades — a Consensus of the FASB Emerging Issues Task Force." ASU 2010-13 addresses whether an entity should classify a share-based payment award as equity or a liability if the award's exercise price is denominated in the currency in which the underlying security trades and that currency is different from the (1) entity's functional currency, (2) functional currency of the foreign operation for which the employee provides services, and (3) payroll currency of the employee. Under the existing guidance in ASC 718-10, "Compensation-Stock Compensation," the Company does not classify any of its stock-based compensation as liabilities. ASU 2010-13 was effective for the Company beginning on January 1, 2011.The adoption of ASU 2010-13 does not change the Company's current accounting for its stock-based compensation awards as ASU 2010-13's application contains an exception for share-based payments that, like the Company's, use exercise prices denominated in the currency of the market in which substantial portions of the entity's equity securities trade. In September 2011, the FASB issued ASU 2011-08, which gives entities testing goodwill for impairment the option of performing a qualitative assessment before calculating the fair value of a reporting unit in step 1 of the goodwill impairment test. If entities determine, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment testing would be required. Otherwise, further testing would not be needed. This ASU is effective for all entities for annual and interim goodwill impairment testing performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company expects it will early adopt this guidance for purposes of our 2011 annual and interim goodwill impairment testing performed. Pending Adoption of Recently Issued Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company's management believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company's consolidated financial statements upon adoption. In December 2010, the FASB issued ASU 2010-28, which modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This ASU is effective for us beginning January 1, 2012. The adoption of this standard is not expected to have an impact on our financial position or results of operations because none of our reporting units have zero or negative carrying amounts. In May 2011, the FASB issued ASU 2011-04, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS," which amends 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 are effective for the Company beginning January 1, 2012 and are required to be applied prospectively, with early adoption not permitted. Since ASU 2011-04 is a disclosure-only standard, its adoption will not affect the Company's results of operations, financial condition, or cash flows. In September 2011, the FASB issued ASU 2011-05, which revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC 220 and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The ASU does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. Also the earnings per share computations will not change and will continue to be based on net income. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company anticipates adopting the ASU on January 1, 2012 using two separate statements of net income and other comprehensive income.

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, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011.

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, 2010.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

Derivative Financial Instruments

Derivative financial instruments are generally used to manage certain interest rate risks through the use of interest rate swaps. These instruments, when settled, impact the Company's cash flows from operations. On the date in which the Company enters into a derivative, the derivative is designated as a hedge of the identified exposure. The Company measures effectiveness of its hedging relationships both at hedge inception and on an ongoing basis.

Gains and losses on interest rate swaps designated as cash flow hedges, to the extent that the hedge relationship has been effective, are deferred in other comprehensive income and recognized in interest expense over the period in which the Company recognizes interest expense on the related debt instrument.

Any ineffectiveness on these instruments is immediately recognized in interest expense in the period that the ineffectiveness occurs. No significant ineffectiveness was recorded on designated hedges in the three and nine month periods ended September 30, 2010, respectively.

All interest rate swaps to which the Company was a party matured prior to the beginning of 2011.

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 foreign currency transactions of these subsidiaries are included in net income. The Company recognized foreign exchange gains of $0.53 million and $0.64 million for each of the three months ended September 30, 2011 and 2010. The Company recognized foreign exchange gains of $0.65 million and $0.66 million for the nine months ended September 30, 2011 and September 30, 2010, respectively, which are classified within other income, net in the unaudited Consolidated Statements of Income.

Comprehensive Income (Loss)

Comprehensive income (loss) 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's accumulated other comprehensive loss includes foreign currency translation losses of $8.6 million and $6.8 million and the unrealized loss on interest rate swaps of $0 and $0.8 million for the nine months ended September 30, 2011 and 2010, respectively.

Adoption of New Accounting Standards

In January 2010, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2010-06, "Improving Disclosures About Fair Value Measurements," which amends Accounting Standards Codification ("ASC") 820, "Fair Value Measurements and Disclosures," to add new requirements for disclosures about transfers into and out of Levels 1 and 2 of the fair value hierarchy and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements within the fair value hierarchy. This ASU also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. This ASU was effective for the Company beginning January 1, 2010, except for the requirements to provide the Level 3 activity of purchases, sales, issuance, and settlements, if any, which were effective for the Company beginning January 1, 2011. Since ASU 2010-06 is a disclosure-only standard, its adoption had no impact on the Company's results of operations, financial condition, or cash flows.

In October 2009, the FASB issued ASU 2009-13, "Multiple Revenue Arrangements - a Consensus of the FASB Emerging Issues Task Force" which supersedes certain guidance in ASC 605-25, "Revenue Recognition-Multiple Element Arrangements," and requires an entity to allocate arrangement consideration to all of its deliverables at the inception of an arrangement based on their relative selling prices (i.e., the relative-selling-price method). The use of the residual method of allocation will no longer be permitted in circumstances in which an entity recognized revenue for an arrangement with multiple deliverables subject to ASC 605-25. ASU 2009-13 also requires additional disclosures. The Company adopted the provisions of ASU 2009-13 beginning on January 1, 2011. Based on the Company's current revenue arrangements, the adoption of ASU 2009-13 did not have a material impact on the Company's financial condition, results of operations, or cash flows.

In April 2010, the FASB issued ASU 2010-13, "Compensation-Stock Compensation (Topic 718) — Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the Market in Which the Underlying Equity Security Trades — a Consensus of the FASB Emerging Issues Task Force." ASU 2010-13 addresses whether an entity should classify a share-based payment award as equity or a liability if the award's exercise price is denominated in the currency in which the underlying security trades and that currency is different from the (1) entity's functional currency, (2) functional currency of the foreign operation for which the employee provides services, and (3) payroll currency of the employee. Under the existing guidance in ASC 718-10, "Compensation-Stock Compensation," the Company does not classify any of its stock-based compensation as liabilities. ASU 2010-13 was effective for the Company beginning on January 1, 2011.The adoption of ASU 2010-13 does not change the Company's current accounting for its stock-based compensation awards as ASU 2010-13's application contains an exception for share-based payments that, like the Company's, use exercise prices denominated in the currency of the market in which substantial portions of the entity's equity securities trade.

In September 2011, the FASB issued ASU 2011-08, which gives entities testing goodwill for impairment the option of performing a qualitative assessment before calculating the fair value of a reporting unit in step 1 of the goodwill impairment test. If entities determine, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment testing would be required. Otherwise, further testing would not be needed. This ASU is effective for all entities for annual and interim goodwill impairment testing performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company expects it will early adopt this guidance for purposes of our 2011 annual and interim goodwill impairment testing performed.

Pending Adoption of Recently Issued Accounting Standards

From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company's management believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company's consolidated financial statements upon adoption.

In December 2010, the FASB issued ASU 2010-28, which modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This ASU is effective for us beginning January 1, 2012. The adoption of this standard is not expected to have an impact on our financial position or results of operations because none of our reporting units have zero or negative carrying amounts.

In May 2011, the FASB issued ASU 2011-04, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS," which amends 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 are effective for the Company beginning January 1, 2012 and are required to be applied prospectively, with early adoption not permitted. Since ASU 2011-04 is a disclosure-only standard, its adoption will not affect the Company's results of operations, financial condition, or cash flows.

In September 2011, the FASB issued ASU 2011-05, which revises the manner in which entities present comprehensive income in their financial statements. The new guidance removes the presentation options in ASC 220 and requires entities to report components of comprehensive income in either (1) a continuous statement of comprehensive income or (2) two separate but consecutive statements. The ASU does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. Also the earnings per share computations will not change and will continue to be based on net income. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company anticipates adopting the ASU on January 1, 2012 using two separate statements of net income and other comprehensive income.
