Spot factoring (single-invoice factoring) lets you factor one invoice — or a few you choose — instead of committing your whole receivables ledger. There's typically no long-term contract and no monthly minimum, so you use it only when you need cash against a specific invoice. The trade-off: the fee per invoice is usually higher than a whole-ledger program. It's built for occasional, one-off cash needs rather than steady monthly funding.
Quick Answer: Most people picture invoice factoring as an ongoing program where you sell most of your invoices to a factor every month. Spot factoring is the opposite: you factor a single invoice (or a handful you select) on demand, with no long-term contract and no monthly minimum. It's the most flexible form of factoring — you tap it only when a specific invoice is tying up cash you need now — and you pay for that flexibility with a somewhat higher fee per invoice. Used for the right situations, it's a clean way to cover a one-off gap without locking your whole ledger into a contract. Get matched to find factors who do spot deals.
What Spot Factoring Is
Spot factoring — also called single-invoice or selective factoring — is factoring applied to one invoice at a time. You pick a specific invoice from a creditworthy customer, the factor advances most of its value (commonly 80-95%), and when your customer pays, you get the reserve back minus the fee. The defining feature is that nothing else is committed: you're not pledging your other invoices, you're not signing up for a year, and you're not agreeing to factor a minimum amount each month. The next time you need cash, you can factor another invoice — or not. It turns factoring from a standing relationship into an on-demand tool you reach for only when a particular receivable is the thing standing between you and the cash you need.
Spot vs Whole-Ledger (Contract) Factoring
Traditional factoring is usually whole-ledger (sometimes called contract factoring): you commit all or a large, defined portion of your accounts receivable to one factor under an ongoing agreement, often with a monthly minimum volume and a term of a year or more. In exchange for that committed volume, the factor offers a lower per-invoice fee and a smooth, predictable funding relationship. Spot factoring trades that commitment for flexibility: no minimums, no long term, factor only what you choose. The cost of that flexibility is a higher fee on each spot invoice, because the factor isn't getting guaranteed volume to price against. Neither is universally better — they solve different problems.
| Feature | Spot (single-invoice) | Whole-ledger (contract) |
|---|---|---|
| What you commit | One invoice at a time | All / most receivables |
| Contract & term | None or minimal | Ongoing, often 12+ months |
| Monthly minimum | Typically none | Common |
| Fee per invoice | Higher | Lower |
| Best for | Occasional / one-off needs | Steady, ongoing cash flow |

When Spot Factoring Makes Sense
Spot factoring shines in situations that are occasional rather than chronic. A few classic cases: a single unusually large invoice from a slow-paying customer is tying up cash you need for payroll or materials; a seasonal business hits one tight stretch but doesn't want a year-round contract; you land a one-time opportunity — a big order, a bulk material discount, an unexpected job — and need to bridge to one specific payment to take it; or you're testing factoring before committing to a full program. In each case you have a specific invoice and a specific gap, and you'd rather pay a premium once than sign up for an ongoing facility you'll mostly not need.
When It Doesn't (Use Whole-Ledger or a Line Instead)
If you need cash against most of your invoices most months — in other words, the payroll-to-payment gap is a permanent feature of your business — spot factoring's higher per-invoice fee adds up fast, and a committed whole-ledger program will almost always be cheaper. Similarly, if you want flexible, revolving access to cash that isn't tied to specific invoices, a business line of credit may serve you better and at lower cost if you qualify. The honest rule of thumb: spot factoring is a scalpel for occasional needs; for ongoing cash-flow management, reach for whole-ledger factoring or a line of credit.

A Cost Example
Say you have a single $50,000 invoice from a solid customer who pays in 60 days, and you need the cash now to make payroll and start the next job. A spot factor might advance 90% ($45,000) right away and charge a fee in the low-single-digit percent for the period the invoice is outstanding — for illustration, a 3% fee would be $1,500, leaving you the reserve (the remaining $5,000) minus that fee when the customer pays. You've turned a 60-day wait into same-week cash for a one-time, known cost, with nothing else committed. These figures are illustrative, not a quote — your actual advance and fee depend on the customer's credit, the invoice, and the factor — but the shape is the point: you pay a defined premium on one invoice to pull its cash forward, and you walk away with no ongoing obligation.
What to Watch For
Even on a one-off deal, read the terms. Confirm it's genuinely no-commitment — some "spot" offers quietly include a minimum or a right of first refusal on future invoices. Check whether it's recourse or non-recourse (most spot deals are recourse), and what happens if your customer pays late or disputes the invoice; see recourse vs non-recourse factoring. Ask about verification — the factor will typically confirm the invoice with your customer, which means your customer learns you're factoring it, the same as in any factoring arrangement. And get the all-in cost, including any wire or processing fees, so you can compare the true price of pulling that invoice forward against simply waiting or using another tool.
Next Steps
Decide first whether your need is occasional or ongoing — that single question usually settles spot versus whole-ledger. If it's a one-off, identify the specific invoice and customer, since the customer's credit drives both eligibility and price, and have the invoice and backup documentation ready so the factor can verify and fund quickly. Then compare a couple of spot offers on the all-in cost and terms rather than the headline rate. To ground yourself in the mechanics first, read what is invoice factoring, and when you're ready, get matched with factors who handle single-invoice deals.
Frequently Asked Questions
What is spot factoring?
Spot factoring, also called single-invoice factoring, is factoring one invoice (or a few selected invoices) at a time instead of committing your whole accounts receivable ledger. There's usually no long-term contract or monthly minimum, so you use it only when you need cash against a specific invoice.
How is spot factoring different from regular factoring?
Regular (whole-ledger or contract) factoring commits all or a large share of your invoices to one factor under an ongoing agreement, often with monthly minimums. Spot factoring is selective and on-demand, factoring individual invoices with no commitment, which means more flexibility but typically a higher per-invoice fee.
Is spot factoring more expensive?
Per invoice, usually yes. Because the factor isn't getting committed volume, the fee on a single spot-factored invoice is generally higher than the rate on a whole-ledger program. The trade-off is that you only pay when you use it and avoid minimums and long contracts, which can make it cheaper overall if you factor only occasionally.
When should you use spot factoring?
Spot factoring fits occasional or one-off cash needs: a single large invoice from a slow-paying customer, a seasonal crunch, or a one-time opportunity you need cash to take. If you need steady cash flow against most of your invoices every month, whole-ledger factoring or a line of credit is usually a better long-term fit.
