How Do Exporters Record Foreign Currency Invoices in Their Books?

Accounting for foreign currency invoices means converting each invoice into rupees, carrying the unpaid amount until it is settled, and recording the exchange difference when the money arrives. AS 11, paragraph 8 treats the sale of services priced in a foreign currency as a foreign currency transaction, so these rules apply to most export invoices.

• Booking rate: The invoice is recorded in rupees at the exchange rate on the date of the transaction (AS 11, paragraph 9).
• Average rate: A weekly or monthly average rate may be used for practical reasons, but it is unreliable when rates move sharply (AS 11, paragraph 10).
• Year end: Receivables are monetary items, so an unpaid invoice is reported at the closing rate on each balance sheet date (AS 11, paragraphs 11 and 12).
• Differences: Exchange differences on settlement or restatement are recognised as income or expense in the period they arise (AS 11, paragraph 13).
• GST export: A supply counts as an export of services only if, among other conditions, payment is received in convertible foreign exchange or in rupees where RBI permits (IGST Act, section 2(6)).
• Income tax: Gains or losses from changes in foreign exchange rates on foreign currency transactions are treated as income or loss and computed as per the income computation and disclosure standards notified under section 276(2) (Income-tax Act, 2025, section 43).

For how the resulting gain or loss is taxed, see forex gain or loss on exports. For the invoice itself, see export invoice format.

Anyone who bills an overseas client in a foreign currency and keeps books of account needs a consistent way to convert those invoices into rupees. The detail you need depends on whether you maintain full books, which accounting system you follow, and whether you report the export value under GST.

You record the invoice in rupees on the invoice date, restate it at the closing rate if it is still unpaid at year end, and close it when the money is credited. The steps below follow AS 11, paragraphs 9 to 14. Your accountant may adapt the ledger names.

1. Raise the invoice in the foreign currency and note the invoice date. For GST, a services invoice is due within thirty days of the date of supply of the service (CGST Rule 47).
2. Pick the exchange rate for the invoice date and apply it to the foreign currency amount (AS 11, paragraph 9). Use the same source of rates for every invoice.
3. Post the entry: debit the client (trade receivable) and credit export sales or professional receipts with the rupee value. Keep the foreign currency amount in the ledger narration or a multi-currency field.
4. At each balance sheet date, restate every unpaid foreign currency invoice at the closing rate and post the difference to a foreign exchange gain or loss account (AS 11, paragraphs 11 and 13).
5. When the payment is credited, debit the bank with the rupee amount actually received, credit the client with the carrying value of the invoice, and post the balance to foreign exchange gain or loss.
6. If the bank or an intermediary deducts charges, record them as a bank charges expense so the client ledger closes at the full invoice value.
7. Match the bank advice or FIRA to the invoice, and keep both with your books. See what is FIRA.
8. If the client paid less than the invoice for a genuine reason, ask your AD bank to record the reduced realisation (FEMA Regulations 2026, Regulation 6).

You need the invoice, the exchange rate used on the invoice date, the bank credit advice or FIRA, and the closing rate at year end for unpaid invoices. Each document supports a different entry, and keeping them together makes GST, income tax and FEMA reconciliation simpler.

Recording invoices at the wrong rate misstates income, receivables and the forex gain or loss. It can also create mismatches between your books, GST returns and bank records. If the Assessing Officer is not satisfied with the correctness or completeness of your accounts, an assessment may be made under section 276(3) of the Income-tax Act, 2025.

• Income tax: Exchange gains or losses are part of income and must be computed as per the notified standards (Income-tax Act, 2025, section 43(1)); a wrong rate shifts income between years.
• GST: The value of exported services in GST returns depends on the rate for the date of time of supply (CGST Rule 34(2)), so a different rate creates a value mismatch.
• FEMA: An invoice that looks short-paid in your books may remain open in EDPMS until realisation or reduction is recorded (FEMA Regulations 2026, Regulations 5 and 6).
• Disclosure: Entities following AS 11 must disclose the exchange differences included in net profit or loss for the period (AS 11, paragraph 40).

Re-check each invoice against your rate record, correct entries in the open year with your accountant, and reconcile the client ledger with bank credits and FIRAs. If a foreign client paid less for a genuine reason, ask your AD bank about reduction under Regulation 6. See short realisation of export proceeds.

The forex gain or loss is the rupee amount received minus the rupee value at which the invoice was last carried. Say a consultant invoices USD 2,000 on 10 March when the hypothetical rate is Rs 83.00, booking Rs 1,66,000. On 31 March the hypothetical closing rate is Rs 83.50, so the receivable becomes Rs 1,67,000 and a Rs 1,000 gain falls in that year. On 25 April the bank credits USD 2,000 at a hypothetical Rs 84.00, which is Rs 1,68,000, so a further Rs 1,000 gain falls in the next year. This split follows AS 11, paragraph 14, which recognises the change in each period up to settlement. All rates here are illustrative only.

• Booking at receipt: A mercantile-basis exporter records the sale only when money arrives, at the credited amount, instead of at the invoice date rate (AS 11, paragraph 9).
• Mixed rate sources: Using a bank rate for some invoices and a reference rate for others makes the books hard to explain; pick one source and document it.
• No year-end restatement: Unpaid invoices are left at the original rate on 31 March instead of the closing rate (AS 11, paragraph 11).
• Fees netted: Bank charges are netted against sales, so the client ledger never closes at the invoiced amount; record them as an expense.
• Gain as sales: Exchange gains are added to export sales instead of a separate forex gain or loss account, which hides them from the disclosure required by AS 11, paragraph 40.
• GST date: The GST value is taken at the payment date when the invoice was raised on time and earlier; time of supply is the earlier of invoice date or payment (CGST Act, section 13(2)).
