An order or inventory buy you cannot fund from cash
A customer places an order, or a supplier prices a volume you can move, and the gross margin on that specific deal is larger than the total cost of the advance. You buy, you deliver, and the revenue the stock produced covers the payments. Both numbers are knowable before you sign.
Bridging a receivable you can evidence
The work is done, the invoice is issued, and payment is contractually due inside the term. The advance covers the gap between doing the work and being paid for it. Check when that customer actually pays rather than when they are meant to. If they habitually run late, the gap is longer than the paperwork says.
Equipment that pays for itself
A machine, vehicle or fit-out that adds capacity or removes a cost, where the extra margin over the term clearly exceeds what the advance costs. Equipment financing is cheaper if you have time to arrange it. An advance makes sense when the equipment has to be earning now.
A seasonal ramp you can evidence
Last year's deposits show the same ramp, and you need stock, staff or marketing in place before it starts. Match the term to the season: repayment runs 5 to 18 months, and it should still be running when the revenue lands, not finished before it.
A bank declined you on credit score alone
Deposits are strong and the business is profitable, but the file failed on a personal credit number. Funders weight deposits more heavily than banks do, which is why scores from 500 to 600+ are considered at all. That is a real reason to use an advance, and it is also why it costs more.
