A payment that went through twice: how it was resolved Writing it up because I had to work it out twice and would rather nobody else did.
A payments question, with the mechanics separated from the money.
What I would like to understand is what each payment route actually leaves you holding afterwards: what is recorded, who holds the record, and what can be produced later if a consignment has to be discussed. That is a different question from which route is cheapest.
I have listed what I keep at the moment below. I would like to know what is missing from it rather than whether it is enough.
