Hi there, @jared-thinline-c.
Thanks for taking the time to reach out to the QuickBooks Community for support.
To clarify, are you using multi-currency in QuickBooks Online? If so, I wanted to mention that you can assign a single currency to most types of accounts, including customers, vendors, bank and credit card accounts, accounts receivable, and accounts payable. That said, it sounds like assigning a single currency to your credit card account is something you may need to do.
To do this, you'll need to add a new account for each different currency you use in transactions. Here's how:
- Click on the Gear Icon.
- Choose Chart of Accounts.
- Select New.
- In the Account dialog, pick the appropriate Account Type and Detail Type.
- Enter a Name for the new account and an optional Description.
- Tap on the currency to assign to the account from the Currency dropdown menu.
- Hit Save and close.
For additional details about this process, check out How to add a foreign currency account.
I've also gone ahead and included a couple of handy help articles that you may find beneficial below that covers more information about using multi-currency in QuickBooks Online.
Please let me know if you have further questions or concerns. I'm always here to lend a hand. Take care!
