Hey there, @Marianne.
Thanks for following up with us and letting us know that you're using QuickBooks Online.
As mentioned by my colleagues above, the best solution is to consult with your accounting professional. Your accountant will know what would be the best steps to take for your business. If you don't have an accountant, don't sweat. You can find one here in our Resource Center.
In the meantime, I've included a few handy articles below that cover more details about multicurrency in QuickBooks Online that you may find beneficial.
Please let me know if you have additional questions or concerns. I'll be here every step of the way. Feel free to reach back out to the Community at any time. Have a great day!
