Multi-currency bookkeeping

Multi-currency bookkeeping covers every transaction billed, paid or settled in a currency other than US dollars: customer invoices, vendor bills, contractor payments, foreign bank and card transactions, and intercompany transfers involving a foreign entity. Each one is recorded in its original currency first, then converted using the exchange rate in effect on the transaction date, sourced from a consistent published rate feed inside your accounting software rather than a rate picked by hand each time. At period close, any account balance still denominated in a foreign currency is revalued at the rate in effect on the last day of the period, and the movement since the last revaluation is posted as a realized gain or loss (for settled items) or unrealized gain or loss (for items still open). Multi-entity structures with a foreign subsidiary get their intercompany balances revalued the same way, so consolidation does not introduce a plug.

Onboarding starts with a review of which currencies actually move through the business, which bank and card accounts hold foreign balances, and which of QuickBooks Online, Xero or NetSuite's multi-currency modules you already have turned on. From there, monthly work follows the same close calendar as your regular bookkeeping: transactions get coded and converted as they post, foreign accounts get reconciled against their native-currency statements, and revaluation entries run at close alongside your regular accruals. A short note in your monthly package calls out any exchange gain or loss large enough to matter, so it never arrives as a surprise buried in a balance sheet line.

This fits any US business with recurring activity in more than one currency: a SaaS company invoicing international customers in local currency, an ecommerce seller paid out by a marketplace in pounds, euros or Canadian dollars alongside US dollars, a services firm paying an overseas contractor team directly rather than through a US payroll processor, or a company with a foreign subsidiary or a loan denominated abroad. It is less relevant for a business that only ever converts currency once, at the bank, before the transaction reaches your books; in that case the bank has already done the conversion and there is nothing left to track separately.

The most frequent issue is a foreign-currency transaction recorded at whatever rate the bank feed shows on the day it clears, rather than the rate on the transaction date, which quietly overstates or understates revenue and expense all year. The second is exchange gains and losses left inside operating accounts instead of their own line, which makes gross margin look like it moved when currency, not the business, actually moved. The third is a foreign bank account reconciled in dollars against a statement printed in its own currency, which almost never balances cleanly and tends to get force-adjusted rather than investigated. The fourth is a foreign loan or intercompany balance that never gets revalued after the initial entry, so the balance sheet carries a number that stopped being accurate the month after it was booked.

Multi-currency bookkeeping runs inside QuickBooks Online's multi-currency feature, Xero's multi-currency add-on, or NetSuite's native multi-currency and consolidation engine, depending on which platform you already run and how many entities or currencies are involved. Wise Business and Payoneer accounts get connected as native foreign-currency bank feeds where the bank itself does not offer one. Marketplace connectors such as A2X or Link My Books translate settlement reports that mix currencies into transaction-level detail your books can actually use, rather than a single converted deposit figure.

Multi-currency work is priced as part of your monthly bookkeeping engagement, not as a flat add-on fee, because the added effort scales with the number of currencies and foreign accounts involved rather than with total transaction volume alone. The published tiers on the pricing page describe the base scope; a business running two or more currencies typically sits in or above the Growth tier once the extra reconciliation and revaluation work is scoped. Your exact fee is confirmed in writing before anything begins, after we see which currencies and accounts are actually involved.

Every monthly close involving foreign currency is reviewed by a senior reviewer before it reaches you, with particular attention to the revaluation entries, since that is where a rate applied to the wrong date or the wrong balance does the most damage to a reported result. You keep access to the underlying QuickBooks Online, Xero or NetSuite file throughout, including the exchange-rate table the software used for each period, so the conversion is never something happening somewhere you cannot verify it yourself.

The single biggest driver of clean multi-currency books is catching the currency and the rate at the moment a transaction is entered, not correcting it later. We set the default currency on each customer, vendor and bank account at onboarding so new transactions post correctly from day one, and we flag any transaction that comes in without a clear currency designation before it gets coded, rather than guessing and fixing it at close. That upfront discipline is what keeps a multi-currency file from turning into a monthly reconciliation project.
