Short answer: your Check Cherry account operates in a single currency, and you can't switch individual clients or invoices to a different one. The good news is you almost never need to. Clients in other countries can still book and pay you without any issue.
Your Account Uses One Currency
Your account's currency is set by your country and applies to everything: packages, proposals, invoices, and payments. There's no per-client or per-invoice currency option, so you can't, for example, bill one client in USD and another in CAD from the same account.
Billing Clients in Another Country
Here's the part that surprises people: you don't need a different currency to work with international clients. If you charge a client in your account's currency, their card handles the rest.
For example, if your account is in CAD and you charge a US client 100 CAD, their card is billed 100 CAD, and their own bank automatically converts it to US dollars on their statement at the current exchange rate. They can book, sign, and pay completely normally. The only difference is that your proposal shows the amount in your currency, not theirs.
Why It Works This Way
Each Check Cherry account connects to a single payment processor account, which settles and pays out in one currency tied to your country. Keeping your whole account in that one currency is what lets payouts, refunds, taxes, and reporting all stay consistent and accurate.
If You Truly Need to Bill in Another Currency
If you have a business reason to invoice in an exact foreign amount, say charging a client exactly $100 USD rather than the converted equivalent, that isn't possible within a single account. It would require operating a separate Check Cherry account configured for that country, with its own payment processing and bank account set up locally in that country.
For most businesses this overhead isn't worth it for a handful of clients, but if it's a core part of how you operate, reach out via the chat bubble in the lower right and we can talk through your options.
