A foreign trade company's books run several currencies at once — US dollars, euros, Japanese yen — yet the financial statements ultimately fold back into the RMB functional currency. Exchange rates fluctuate daily, and the gap from contracting and quoting to collection and settlement often spans months. If the exchange gains and losses that arise in between aren't handled cleanly, profit becomes impossible to pin down. This article explains the key conventions of multi-currency accounting — from bookkeeping rates and exchange gains/losses to FX locking, settlement and FX write-off — to help finance get foreign-currency business right.
The first step in multi-currency accounting is to decide the translation-rate convention for foreign-currency business. There are two common approaches: using the spot rate on the transaction date, or using a uniform bookkeeping rate set at the start of the month (or period). Whichever you choose, the key is that the convention is consistent across the whole company and consistent period to period. A systematic financial settlement maintains a daily rate table, and business documents automatically pick the rate by the set rule to translate amounts into the functional currency, avoiding arbitrary, inconsistent manual rate-picking. Note especially that foreign-currency assets and liabilities (such as accounts receivable and foreign-currency bank deposits) are monetary items and must be re-translated at the balance-sheet-date rate at period end.
Exchange gains and losses come from rate differences at two types of points in time:
For example: a receivable of USD 100,000 recorded at a rate of 7.10 on contracting, collected at a rate of 7.05, yields RMB 5,000 less actually received; this is charged to finance expense — exchange gains and losses. Once sales, collection and rates are managed together, the system can calculate and generate the exchange gain/loss voucher automatically at collection, saving line-by-line manual computation.
For large-amount, long-tenor orders, rate swings can eat straight into profit. Companies commonly use tools such as forward settlement and FX options to lock the rate, fixing an uncertain future rate in advance. In practice you must distinguish the "locked rate" from the "spot settlement rate," and record the lock contract and its corresponding business order in the system, accounting at the agreed rate when settlement falls due. Linking these to export business orders lets finance see clearly whether each collection used the spot or the locked rate.
After goods are exported and foreign currency received, the company must handle FX write-off, matching the customs-declared exported goods with the actual collection to prove the trade background is genuine. The core of write-off is document-to-document agreement and consistency: the amounts and currencies on the customs declaration, invoice and FX receipt advice must cross-reconcile line by line. Connecting export, collection and financial settlement lets collections automatically link to the corresponding order and customs declaration, aggregating write-off and tax-rebate data together — meeting compliance while greatly reducing finance's reconciliation workload.
Multi-currency accounting is hard because rates move over time and conventions easily drift. Unify the rate table, translation rules, exchange gains/losses, FX locking and settlement, and FX write-off into one system for automatic handling, so every foreign-currency transaction is traceable to its source — only then can foreign trade profit be calculated clearly and seen plainly.
