How can I get invoice numbers in Bank Register ?

Hello there, @user42802.

Thanks for visiting the Community. At the moment, the option to get an invoice number in the bank register is unavailable. 

You can run the Invoices and Received Payments report instead should you need to get the invoice number. This report will show all received payments linked to an invoice. 

Here's how:

1. Go to the Reports menu. 
2. Enter Invoices and Received Payments in the Search field.
3. Under the Report period, click the arrow and set the desired date from the option, then click Run report. 

For future reference, read through this article: Customize Reports: Basics, Sorting & Date Ranges. It includes a quick video tutorial for your visual guide. 

Let me know if you have other questions. I'm always here to assist.
