The gap has been covered in these pages before: small firms invoice on thirty- or sixty-day terms, large customers stretch them further, and the working capital of the small business quietly finances the cash flow of the large one. What deserves its own treatment is the industry built on that gap. Invoice finance - factoring, where a business sells its invoices to a financier who advances most of their value now and collects from the customer later, and its quieter sibling invoice discounting, where the business keeps collecting but borrows against the receivables - has grown into a mainstream funding channel for smaller firms, particularly as banks have tightened conventional lending and payment delays have lengthened. Used well, it converts the slowest asset on the balance sheet into working capital on demand. Used carelessly, it is among the more expensive money a business can rent, with exit costs that surface exactly when the business is least able to pay them.
The mechanics reward close reading, because the headline number is not the price. A factor typically advances a large fraction of an invoice's face value, holds the remainder in reserve, and charges two things: a discount fee on the funds advanced and, often, service charges layered around it. The fee sounds small - low single digits of the invoice - but it is charged per invoice cycle, not per year: a modest-sounding percentage for thirty days of financing, annualised, lands in the range of expensive credit, and the shorter the payment cycle, the higher the effective rate climbs. The contract carries the rest of the price. Recourse clauses - standard in most agreements - return the invoice to the business if the customer fails to pay, meaning the financier bore administration, not credit risk. Concentration limits, minimum volumes, whole-ledger requirements and notice periods bind flexibility. The question that cuts through every proposal: what is the effective annual cost of this money, all fees included, and who holds the loss if the customer never pays? A provider who answers plainly is quoting; one who redirects to the headline fee is selling.
Where factoring genuinely earns its place is narrower than its marketing but real. The strong case is growth outpacing capital: a business whose orders are expanding faster than its cash cycle can fund - where the alternative to expensive working capital is declining profitable work - is buying growth with the fee, and the arithmetic can be soundly positive. It also fits businesses whose customers are slow but solid: creditworthy payers on long terms are exactly the receivables a financier prices best. The weak case is the one the industry's growth statistics quietly include: factoring adopted not to fund growth but to plug a structural loss, where the fees accelerate the decline they defer - a business that needs to finance its invoices to cover routine costs has a margin problem or a pricing problem, and no financing product repairs those. And one operational note bears weight: in classic factoring the financier collects from your customers directly, which discloses the arrangement and inserts a third party into relationships you may have spent years building - discounting variants keep collection, and the disclosure, in your hands at a somewhat higher bar of eligibility.
The disciplined posture treats invoice finance as one tool on a shelf, priced against its neighbours rather than accepted in isolation. Before the factoring contract, the cheaper levers deserve their chance: tighter terms offered with early-payment discounts priced deliberately rather than desperately; deposits and staged billing that shrink the receivable itself; the statutory late-payment interest that in many jurisdictions exists precisely for stretched terms and goes largely unclaimed; and the customer-concentration work already covered here, since the invoice most worth financing is often the customer most worth renegotiating. Where the gap survives all of that - and in growth phases it legitimately does - factoring belongs in the comparison alongside overdrafts, term loans and the newer embedded-finance advances, judged on effective annual cost, recourse, and exit terms. Money against invoices is neither rescue nor trap. It is a price, and the businesses it serves are the ones that read it as one.
