QuickBooks Online Multicurrency: the switch you cannot flip back
Turning on Multicurrency in QuickBooks Online is a one-way switch; we cover the home currency lock, per-currency accounts and cross-currency deposits.
Across QuickBooks Online subscriptions, one Multicurrency question recurs more than any other: how to undo it. The feature does its job well, but the switch that enables it is permanent. We walked through the whole workflow, from the home currency lock to deposits that cross currencies, and pulled together what actually works.
Which plans include Multicurrency?
Intuit ships the feature with QuickBooks Online Essentials, Plus and Advanced. If your subscription sits below those tiers, the option does not appear at all. An upgrade comes first, before a single euro or dollar invoice can be recorded.
What does Multicurrency do?
Once it is on, you can record invoices, bills, payments and receipts in currencies other than your home currency. The software converts every entry back to your home currency for reporting. You assign one currency to each customer, supplier, bank account, credit card account and debtor account. Income and expense accounts are the exception. They always stay in your home currency.
Turning it on is a one-way door
The setting lives under Settings, then Account and settings, then Advanced. Open the Currency section and set your home currency first, because that choice is editable only while Multicurrency is still off. Then flip the switch and confirm the warning that appears.
The warning is blunt for a reason. There is no off switch. Once enabled, the feature stays on for the life of the company file, and the home currency is locked with it. Users who enable it out of curiosity, then ask how to reverse the decision, discover that the only escape is a new company file. That design, rather than any malfunction, is the biggest source of frustration around this feature.
Can you change the home currency later?
No. The home currency is set when the company file is created and can be edited only before Multicurrency goes on. After that, the dropdown is fixed. If your business relocates or changes its base money, the practical answer is a fresh file with the right currency chosen on day one.
Adding and removing currencies
New currencies are added from the Currencies page, which appears under Settings only after the feature is enabled. Pick a currency from the dropdown and add it. The page also shows the rate on file for each one. Deleting works in reverse and carries one hard condition: a currency can be removed only while no transactions use it. Once a single invoice or payment touches that currency, the delete action is gone for good.
Accounts carry one currency each
Most account types hold a single currency for life. You cannot switch an existing bank account from pounds to euros, so the route is a second account in the second currency, used wherever it applies. The same rule governs customer and supplier records, and that is where it bites hardest.
A customer’s currency cannot be edited
Once a customer or supplier has a currency assigned, and certainly once they have transactions, that assignment is fixed. The standard workaround is a new profile. Create a second customer record in the required currency, use it going forward, and make the original record inactive once its balance clears. History stays behind on the old profile.
Who sets the exchange rates?
QuickBooks maintains its own rate feed for the currencies you enable and refreshes those figures automatically. On any individual transaction you can accept the downloaded rate or type the rate your bank or card processor actually gave you. The override matters, because processor rates rarely match the mid-market number. When the rate moves between invoice and payment, the software posts the difference to an exchange gain or loss account on its own.
Deposits that cross currencies
A payment received in one currency cannot be deposited straight into a bank account held in another. The pairing is blocked rather than converted silently. The working route is a transfer. Record the receipt, then move the money between the two accounts and enter the amount that actually landed. Any gap against the booked value posts as an exchange gain or loss. The books stay honest, but the detour is manual, and it surprises first-time users.
Payroll stays in the home currency
Multicurrency reaches customers, suppliers and bank accounts, not wages. Payroll calculates and records in your home currency, so an overseas employee’s pay cannot be run through it in their local money. Payments of that kind sit outside the payroll run and are recorded against the foreign-currency account by hand.
Before you flip the switch
The pattern across these reports is consistent. Decide your home currency before anything else. Plan one account per currency you intend to hold. If you are unsure, rehearse the feature in a trial company file rather than your live books. The tool itself behaves as documented; it is the one-way design that deserves your full attention before you commit.
