How to issue a receipt for my customer who makes partial payment for a Tax Invoice?
If the customer took possession of all 10 items when you delivered then you are correct to bill all 10 on the first tax invoice. Does your accounting software offer the option of printing a customer statement with the detail of transactions over a range of dates? If so, that would show the customer the status of their account and also the detail of charges and payments to date. I agree, things start to get confusing when you get into “A”s and “B”‘s etc.
