Multi-currency accounting: points to secure

Updated March 30, 2026 - Maintaining multi-currency accounting is not just about recording amounts in dollars or pounds. In 2026, we must secure conversion, exchange differences, closure and the real impact on margin and cash flow.

As soon as the company invoices, purchases or holds balances in foreign currency, it must make the operational flow and the accounting reading in euros coexist. This requires a consistent conversion method and a revaluation of certain positions at closing.

• ▸date and source of the conversion rate;
• ▸processing of customer and supplier invoices;
• ▸settlement discrepancies;
• ▸revaluation of receivables and debts at closing;
• ▸monitoring of currency accounts;
• ▸impact on results and cash.

The closing is the real sensitive moment

At the closing, receivables and debts in foreign currencies must be the subject of particular attention. This is often where the most costly errors in results or balance sheets arise.

Hayot Expertise advice: in multi-currency, the danger is not only accounting. It is also managerial: if the exchange rate differences are misread, the apparent margin can become misleading.

• ▸use inconsistent rates depending on the files;
• ▸forget about payment discrepancies;
• ▸not properly reassessing certain closing positions;
• ▸confuse commercial performance and exchange rate effect.

We recommend documenting:

• ▸the official rate source;
• ▸internal conversion rules;
• ▸processing partial payments;
• ▸the accounting scheme for differences;
• ▸margin reporting excluding effects changes if necessary.

We can help you establish a simple, documented method that is compatible with your closing tools and controls.
