Invoice discounting and factoring do the same job, which is to turn a receivable into cash now, and they differ in two ways that decide which one a business can have: who chases the customer for payment, and whether the customer is told at all. Everything people call an advantage or a disadvantage of discounting follows from those two facts, so it is worth starting there rather than with a list.
The two differences that decide everything
In a discounting facility you keep your own credit control: your customers pay you as normal, they are usually never told a lender is involved, and you sweep the receipts to the funder. In a factoring facility the funder collects, in its own name, and the customer knows. That is the whole distinction, and every consequence flows from it. Discounting protects the customer relationship and costs less because the funder is doing less work; factoring hands a small business a credit control function it may not otherwise have, and costs more because that function is real.
The advantages, stated honestly
Cash arrives against a receivable in days rather than in the thirty to sixty the terms allow, without adding a fixed monthly instalment to the business. The facility grows with the ledger rather than being renegotiated at a fixed limit, which suits a business whose sales are climbing faster than a bank will re-underwrite. Confidentiality is real in most discounting facilities and worth paying for where customers would read a factor's involvement as distress. And the credit risk being assessed is largely the customer's, so a business with a thin file and strong customers can often get discounting when it cannot get a loan.
The disadvantages, and the one that catches people
It is not free money: the discount rate and the service fee are charged on turnover, so the cost scales with success. Confidentiality can end: many facilities allow the funder to disclose and collect directly if a customer goes far enough overdue, and that clause is worth reading before the first difficult month rather than during it. There is usually a minimum monthly fee, so a quiet season is charged for anyway, and a notice period of one to twelve months, which makes the facility much harder to leave than to join. And discounting is generally offered only to businesses with credit control good enough to be trusted with the collecting, which is why the smallest businesses are usually offered factoring instead.
Questions people ask about invoice discounting advantages and disadvantages
Is invoice discounting cheaper than factoring?
Usually, because the funder is not doing the collecting. No lender in this record publishes a rate for either, so any figure quoted to you is specific to your ledger and should be given in writing alongside the service fee, the reserve, the minimum monthly charge and the notice period.
Will my customers know I am using invoice discounting?
Normally not, which is the main reason businesses choose it. Read the disclosure clause though: most facilities allow the funder to notify and collect directly once an invoice is sufficiently overdue, and that is exactly when you would least want it.
Which is better for a small business?
Discounting is usually offered to larger, better-run ledgers because the funder is relying on your own credit control. A small business with no credit controller is often better served by factoring, where the collecting is part of what it is buying.
