Two places, whichever you're in.
From Money — every unpaid invoice has a button on the row. One tap and it's done; you don't have to open the job.
From the job — the Invoice card has the same tick.
Once marked, it drops out of what you're owed, the pill on My quotes turns to Paid, and it counts towards what came in this month.
GafferMate doesn't watch your bank account. It knows an invoice is paid because you told it.
