Hi, Can we edit an existing customer with balances in one currency and change it to another currency? thank you

It's great to see you here in the Community forum, abraham. I'll provide some information about editing a customer's currency in QuickBooks Online (QBO).

The currency of a customer cannot currently be changed in QBO. The program's balance currency will be the one you chose at the initial setup for your customer.

That said, I suggest adding a new customer with another currency you want to utilize. Refer to this article for more details about this process: Add and manage customers in QuickBooks Online.

Additionally, you may check out this article to learn how to view all sales transactions and their statuses on the Sales page: View sales transactions in QuickBooks Online.

Let me know if you still have questions or concerns about managing customer transactions in QBO. I'll be here to lend a helping hand. Have a great day ahead!
