Good day to you, @mirek1.
You’ll want to turn on the Multicurrency feature of your QuickBooks Online (QBO) account to change the currency of your estimate. I’d be glad to guide you how:
You can also check this article for more details about using multicurrency: Turn on and use multicurrency.
Once done, you can now change the currency of your estimate.
In addition to this, I’m adding this resource that you can use for future reference. This link can guide you through the steps on how to convert an estimate into an invoice.
In case you have other questions about multicurrency or estimate, you can always tag me in your reply. I’d be more than happy to help you out. Have a great day and stay safe!
Once you enabled the multi currency feature, you have to create a new customer profile and set its currency. Then you will be able to create an estimate or invoice for that customer.
As another option, you may create a virtual business account at TW and utilize the bank feeds. You may create an estimate or invoice in your home currency and your client may pay your invoice in their local currency.
