Best Practice on applying a partial payment with interest on older invoices?
We have a client who has made a partial payment via wire (about 50% owed) against 7 invoices. They wired direct to the bank, so this is a manual entry I'm trying to sort out.
Each invoice incurred 0.5% monthly, non-compounding. In receiving that, do we start with the oldest and apply against principal only or do we cover principal and interest on the oldest, then the next oldest, etc.?
What's the best practice expectation here?
