Payments taken through your own payment links match themselves — the invoice is settled, the fee is booked and the entry is posted without anybody doing anything.
Charges made directly in Stripe have nothing on them saying what they were for. Those land in Payments inbox.
1.Open Payments inbox.
2.Press Find the invoice. Candidates are ranked by email, then amount, then how close in time.
3.Press This is it on the right one.
Why it does not match automatically
An amount and a date are not proof. Two customers owing $1,200 in the same week is an ordinary Tuesday, and a wrong guess settles the wrong invoice while the right one goes on chasing somebody who already paid.
If it is not for an invoice
Press Set aside and say why. That note is the answer when somebody asks about it at year end.
