If i booked a received payment through bank journal, how do I clear the open invoice of the customer afterwards?

Glad to have you here in the Community, @userbrigittequartier.

I can help you clear out the open invoices in QuickBooks Online (QBO).

Here's how:

1. Go to the Sales menu, and then choose Invoices.
2. Locate the invoice which has incurred the bank journal.
3. Select Receive payment on the top right of the invoice.
4. Under the Receive payment page, select the invoice and the Journal Entry.
5. Make sure the Amount received is correct.
6. Select Save and close.

I've added this article about recording payments in QBO: Record invoice payments in QuickBooks Online.

Also, I encourage checking our Help articles page to learn some tips and tricks in managing your QBO account. From there, you can read great articles that can guide you through the steps by steps process.
