How do I see the payments on a service invoice?

1. Open Invoices and press the invoice.
2. History, under its facts, lists the day it was issued and sent, each payment with how it was paid, and the due day, amber once it has passed with an amount still owed.
3. To take off a payment recorded by mistake, press the bin on its line. A payment that came back from your books has no bin; take it off there.
