How to mark an invoice as paid?
Original commenter did not share additional details
Hey Robert17,
Welcome to QuickBooks Online's Community for the UK.
I like to mark my invoices as paid by finding the invoice, double clicking and opening it, and selecting the receive payment option in the top right hand corner of your open invoice.
You can also click the Plus Icon, Select Receive Payment and then select the Invoice you're looking to pay, from the presented list.
