# Create Conversion Reports

Finance teams need to reconcile international transactions, audit historical conversions, and report on FX impacts. When the quarter closes, the question is: how did exchange rate movements affect our international revenue and costs? Did we gain or lose from FX fluctuations compared to budget rates? These reports require historical rate data matched to specific transaction dates.

Historical rates provide the exact rate on any past date, while convert calculates what amounts would have been at different rates. Together they enable retrospective analysis: comparing actual conversion rates to budget rates, calculating FX gains and losses, and building the foreign currency sections of financial reports.

This is essential for financial controllers preparing quarterly and annual reports, auditors verifying foreign currency transactions, budget analysts measuring FX impact on financial performance, and tax teams calculating foreign currency gains and losses. Accurate historical rate data is the foundation of reliable international financial reporting.
