Invoice Finance vs. Purchase-Order Funding

Both fix the same headache — a cash-flow gap — but at opposite ends of a deal. Knowing which one you need is the first step to getting funded fast.

Invoice Discounting / Factoring

You've already done the work or delivered the goods and issued an invoice on 30–90 day terms. The money is owed to you — you just can't wait that long to be paid.

  • The funder advances most of the invoice now.
  • They release the balance, less a fee, once your customer pays.
  • Secured against your debtor's book, not your assets.

Purchase-Order (PO) Funding

You've won an order you can't afford to fulfil. You need cash to pay suppliers and produce or buy the stock before you can invoice and get paid.

  • The funder pays your supplier against a confirmed PO.
  • You deliver, invoice the customer, and the funder is repaid.
  • Lets you say "yes" to big orders without turning them away.

Why this matters for SA SMEs

Late payment is one of the biggest killers of South African small businesses. When corporates and government pay on 60–90 day terms, a profitable order can still sink you if you run out of cash mid-way. Invoice and PO finance turn that paper profit into working capital — but the fee is real, so always compare the cost against simply waiting.
