What is multi-currency bookkeeping?
Foreign-currency transactions, revaluation and realised gain or loss handled consistently.
Multi-currency bookkeeping is its own line of work the moment a US business has a foreign bank account, bills a customer in euros or rupees, or pays a contractor in a currency that isn't dollars. The trigger is usually one of three events: a US company opens a bank account abroad (which also creates an FBAR question), a US company invoices overseas customers in their local currency, or a foreign parent or subsidiary needs its books converted into USD for consolidation. Each of these needs a defined method for turning foreign-currency transactions into US-dollar entries the CPA can actually use.
The core mechanic is simple to state and easy to get wrong in practice: every foreign-currency transaction gets recorded in USD at the exchange rate on the transaction date, and every foreign-currency balance sitting on the books at period end gets revalued to the period-end rate. The gap between the rate at booking and the rate at settlement or revaluation is a gain or loss, and it has to land in the right account and the right period — not get buried in a rounding difference or silently netted against something unrelated.
Why it matters

|---|---|
| Month-end arrives whenever someone gets to it | Books closed on a fixed date, in the same shape every month |
| Unexplained transactions pile up in a suspense account until year-end | Every account reconciled to the statement, with discrepancies explained not plugged |
| Your accountant bills you to fix bookkeeping before they can do their own work | A short questions list instead of a year-end archaeology project |
| You cannot answer "how did we do last month" without a week of digging | Whoever files opens a finished file |

Multi-currency bookkeeping in United States
ASC 830 sets the mechanics, not the elections
US GAAP's foreign currency guidance (ASC 830) is what governs transaction-date recording and period-end revaluation of monetary foreign-currency balances. It also covers functional-currency determination for a foreign subsidiary — which currency that entity's books are kept in before translation to USD for consolidation. We record foreign-currency transactions and revalue balances using the mechanics ASC 830 describes. Deciding what an entity's functional currency IS, or making a functional-currency election, is a judgment call for your CPA — we don't make that determination.
Realized vs. unrealized gain/loss is not optional bookkeeping nuance
A realized gain or loss happens when a foreign-currency transaction actually settles — an invoice gets paid, a bill gets paid, a loan gets repaid — and the settlement rate differs from the booking rate. An unrealized gain or loss happens at period-end revaluation of a balance that has not settled — an open foreign-currency receivable, payable, or bank balance restated to the closing rate. Both are real P&L entries in most cases, but they come from different events and belong in distinct accounts so your CPA can see which is which without unwinding the ledger.
FBAR and Form 8938 are triggered by foreign accounts, not by us
A foreign bank account can trigger FinCEN Form 114 (FBAR) if aggregate foreign account balances exceed the reporting threshold at any point in the year, and separately may trigger Form 8938 depending on filing status and asset thresholds. We maintain the foreign account ledger — balances, currency, dates — as clean source data. Whether FBAR or Form 8938 applies, and filing them, sits with your CPA; we don't make that determination or file on your behalf.
Foreign-currency invoicing doesn't create a nexus determination
Billing an overseas customer in their local currency is a currency-conversion question, not a sales-tax question. It doesn't, by itself, tell you anything about where you owe sales tax or VAT/GST — that's a separate nexus analysis your CPA runs. Multi-currency bookkeeping keeps the foreign-currency invoice and its USD conversion straight; it doesn't answer where the sale is taxable.
What your CPA or enrolled agent receives from us
- Every foreign-currency transaction booked in USD at the transaction-date rate, with the rate and source recorded against the entry
- A named, consistently applied FX rate source (e.g., a specific bank or data feed) documented so the CPA can reproduce any historical rate
- Realized gain/loss on settled foreign-currency invoices and bills, posted to a distinct realized FX gain/loss account
- Period-end revaluation of all open foreign-currency monetary balances — cash, receivables, payables, intercompany loans — to the closing rate
- Unrealized gain/loss from revaluation posted to a distinct unrealized FX account and reversed at the start of the next period
- A foreign bank account listing with account, currency, and month-end USD-equivalent balance, formatted for an FBAR or Form 8938 review
