Spot vs. contract factoring

Spot factoring vs contract factoring comes down to commitment. Spot factoring (also called single-invoice factoring) funds one invoice at a time, at a higher rate, with no obligation to ever send another. Contract factoring commits some or all of your invoices to one factor for a term, and pays you back for that commitment with rates roughly half of spot pricing.

Neither is the better product. They are different prices for the same cash, sorted by how much freedom you keep. The math below shows exactly where the crossover sits for your volume, when the expensive option is genuinely the smart one, and the one contract clause that decides whether you ever get to choose again.

Spot factoring vs contract factoring: the actual difference

Mechanically, both work the same way: deliver the load, submit the invoice and paperwork, receive an advance the same day, and the factor collects from the broker. The advance rates, notice of assignment, and reserve mechanics are identical territory, covered step by step in our guide to how factoring works. What changes is the deal around the mechanics.

Spot factoring is transactional. You pick the invoice, the factor prices it individually, and when it settles you both walk away. No term, no minimum, no obligation to factor the next load. Because the factor cannot spread its underwriting and onboarding cost across a stream of invoices, each one carries the full weight: typical spot pricing runs 4–8% per invoice, and some factors set minimum invoice sizes to make one-off deals worth processing.

Contract factoring is a relationship. You commit invoices for a term (anywhere from month-to-month to 24 months) and the factor prices the whole stream: typically 1.5–4%, with volume tiers that drop as you grow. DAT Outgo's published schedule is the cleanest public example: 3% below $18,000 a month, 2.5% from $18,000 to $80,000, custom above that.

The catch inside contract factoring is scope. A whole-ledger contract with a blanket assignment clause means every invoice goes through the factor, including loads from shippers who pay in ten days. A selective contract preserves choice. Which one is in the paperwork matters more than the rate, and it is the first thing to check against our contract red flags list.

So the products are clear enough. The interesting question is where the money actually crosses over.

The crossover math at your volume

Put real numbers on both options and the decision usually makes itself.

The occasional-need carrier. Say you factor two $2,000 invoices a month, only when a slow broker collides with a fuel week. Spot at 6% costs $240 a month. A contract at 3% would cost $120 on those same invoices, but if the contract carries a $10,000 monthly volume minimum, the shortfall penalty or the fee on loads you never needed to factor erases the saving. At genuinely low, irregular volume, spot's higher rate is the cheaper total.

The factor-everything carrier. Now say you factor $20,000 a month, every load. Spot at 6% costs $1,200 a month, $14,400 a year. A contract at 2.5% costs $500 a month, $6,000 a year. The commitment is worth $8,400 a year, which is not a rounding error; it is a maintenance fund.

The crossover. The break point arrives fast: at roughly $5,000–$8,000 of factored volume per month, contract pricing plus its obligations usually beats spot pricing, and beyond $10,000 it is rarely close. Below that, freedom is cheap and you should keep it.

One more entry on the spot side of the ledger that has nothing to do with rates: spot is how you date a factor before marrying one. Funding speed, verification hassle, and support quality only reveal themselves in live transactions. Two or three spot invoices tell you more about a factor than any sales call, at a total cost of maybe $100 over contract pricing. Cheap tuition.

Which is why the real decision framework is not spot versus contract at all. It is a sequence.

When spot wins, when contract wins

Spot factoring is the right tool when:

• Your need is occasional. Seasonal freight, one chronically slow shipper, or a rare cash crunch. Paying 6% twice a quarter beats owing a contract twelve months a year.
• You are testing a factor. Run live invoices through their process before signing anything. The experience is the due diligence.
• You hold reserves and factor tactically. Carriers who can float most terms sometimes spot-factor only oversized invoices or unknown brokers, buying the factor's credit check and collections exactly where the risk lives.
• Your volume is genuinely small. Below a few thousand dollars a month factored, contract obligations (minimums, terms, exit mechanics) cost more than the rate saves.

Contract factoring is the right tool when:

• You factor most of what you haul. The rate gap compounds on every load; at steady volume it funds real line items.
• You want the full back office. Credit checks on every broker, collections, fuel advances, and one invoicing workflow come standard with committed relationships, rarely with spot deals.
• Your volume is climbing. Tiered schedules reward growth automatically, and a year of clean history is the leverage for the next rate negotiation.
• Predictability matters more than optionality. One known fee on every load makes weekly cash planning boring, in the good way.

The honest sequence for most carriers: spot-test the shortlisted factor with a handful of invoices, then sign the shortest contract that unlocks the volume rate, with the exit terms already vetted. Freedom first, discount second, and never the discount at the price of an exit you have not read. The exit mechanics, buyouts, releases, and notice windows, are their own project, covered in our guide to switching factoring companies.

Applying for each, and the decision in one pass

The application difference mirrors the product difference. A contract application is one onboarding: authority verification, insurance, a broker list, bank details, and the agreement itself, typically approved within a day or two, after which every invoice rides the same rails. A spot application repeats a lighter version per deal: the factor underwrites that broker and that invoice each time, which is exactly why the pricing is heavier. The document list is the same either way, and it is short; the full walkthrough lives in our how factoring works guide.

The decision, compressed:

1. Total your realistic monthly factored volume. Not your gross, the part you would actually factor.
2. Under ~$5,000 a month or truly irregular: stay spot. Ask two factors for spot pricing and minimum invoice sizes, and keep the freedom.
3. Over ~$10,000 a month, factoring most loads: go contract, but spot-test the finalist first and vet the exit clauses like you plan to use them.
4. In between: shortest term you can get, no volume minimum you cannot clear in your slowest month from last year, and revisit at the six-month mark with your volume history as leverage.
