Summary: Multi-currency accounting is a frequent pain point in foreign trade finance implementations, usually caused by inconsistent exchange-rate sources and unclear period-end revaluation scope. This article documents directly applicable rules (demo sample post, not a real project record).
Background
Foreign trade business involves multiple settlement currencies: transactions use trade-date rates, bank settlement uses actual bank rates, and period-end reports restate at closing rates. Without a single source of truth for rates, reported exchange gains and losses become unreliable.
Rules That Work
- One rate table per currency pair with a defined source and timestamp
- Book at trade-date rate; track realized differences at settlement
- Revalue open items at period end with a clearly scoped revaluation batch
Key Takeaways
Agree the rate policy with finance before development starts — changing rate semantics later is expensive.
