Hi there, @qb-solarwind-ltd. I'm here to share some information about using online payments in QuickBooks Online (QBO).
Currently, the ability to add online payments to invoices is only available if you're using the QBO US or UK country version.
As a workaround, I recommend looking for a third-party application for online payment that can be integrated into QBO. You can do this within the program. Here's how:
Open your QBO account and select the Apps menu.
Next, in the search bar enter the keyword for the app you're looking for.
I'd love to know how this goes. If you have any other questions about managing invoices in QBO, please let me know by leaving any comments below. I'm always around ready to lend a hand. Keep safe.
