When you record a transaction in a foreign currency (USD, GBP, EUR, etc.), Zoho Books uses the exchange rate configured for that currency on the transaction date to calculate the INR equivalent. This INR amount is posted to your accounts. If the exchange rate changes between the invoice date and the payment date, the INR values differ. Zoho Books calculates the difference and posts it to a “Foreign Exchange Gain” or “Foreign Exchange Loss” income or expense account automatically.
For major currencies, Zoho Books offers automatic daily rate updates from a live feed. For smaller or less traded currencies, or if your finance policy requires using the RBI reference rate (as recommended for export invoice reporting under FEMA), you set the rate manually. To set a manual rate, go to Settings, then Currencies, select the currency, and enter the rate. The manual rate applies to all new transactions from that point forward until you update it again.
On any invoice, bill, or payment form in Zoho Books, the exchange rate field shows the current configured rate. You can override it for that specific transaction without changing the global rate. This is useful when the bank has applied a slightly different rate to a wire transfer than the system rate. The override ensures the INR amount in Zoho Books matches the actual bank debit or credit, keeping reconciliation clean.
An exchange rate in Zoho Books converts foreign currency amounts to INR at the time a transaction is recorded. Differences between the invoice-date rate and payment-date rate are posted automatically as foreign exchange gains or losses.
Zoho Books can update rates automatically via a daily feed for major currencies. You can also set manual rates. The rate in effect when a transaction is saved determines the INR value recorded, and you can override it on individual transactions.
