Instead of select single Invoice (debtor) finance or financing ledger against all customers on your sales ledger, you would only choose those you want to fund and commit them to the facility.
Once you commit a customer to the facility, you must give all invoices for that customer to the selected invoice finance lender. You will receive two payments from the lender. The first payment will be the initial payment against the total invoice value, known as the advance payment percentage. The second payment is the remainder of the invoice, minus the agreed upon factoring fee.
