# List supplier credits (`purchasing_list_credits`)

Lists credits with suppliers, deposits and overpayments, with what is left on each.

Credits with suppliers, prepayments and overpayments, newest first: what each was, what is left, its VAT and how it was used or came back. Filter by supplier, or status (open, used, refunded, void, all; default open).

Price: Free up to 1,000,000 reads a month for the whole account, then $0.50 per 10,000 reads. A call that fails costs nothing.

## Use it when

Before paying a supplier the business paid ahead, or to see what suppliers hold for it.

## Say this to your agent

> Which suppliers still hold a deposit of ours?
