Spot Factoring vs. Contract Factoring — Which Is Right for You?
Last reviewed: May 2026. All rates are based on lender-published rates as of May 2026.
- Spot factoring costs 0.5–1.5% more per 30-day period than contract factoring — at $50,000/month in consistent volume, contract factoring saves ~$3,000/year
- Contract factoring typically requires a 12-month commitment and minimum monthly volume of $10,000–$50,000; early termination fees run 1–3% of contracted monthly volume
- If your monthly volume falls below a contract minimum, you pay a shortfall fee on the gap — model your slowest months before committing to any volume floor
- Spot factoring is available from Riviera Finance (month-to-month) and RTS Financial (freight, no minimums); eCapital and Triumph Business Capital require contracts with minimums
The Core Difference
Spot factoring (also called selective factoring) lets you submit individual invoices to a factor on a transaction-by-transaction basis — no minimum volume, no long-term contract. Contract factoring requires you to factor all invoices (or a minimum monthly volume) from agreed customers over a defined contract period, typically 12 months. Contract factoring costs less per invoice; spot accounts receivable factoring costs more but gives you complete flexibility.
Side-by-Side Comparison
| Spot Factoring | Contract Factoring | |
|---|---|---|
| Contract required | No | Yes — typically 12 months |
| Min. monthly volume | None (or very low) | $10,000–$50,000 depending on factor |
| Fee premium | +0.5–1.5% per 30 days vs. contract | Baseline |
| Which invoices | You choose each time | All (or all from contracted customers) |
| Termination fee | None | Often 1–3% of contracted monthly volume |
| Best for | Irregular invoice volume, testing a factor | Consistent B2B businesses, high volume |
Spot factoring costs 0.5–1.5% more per 30-day period than contract factoring — at $50,000/month in consistent invoice volume, contract factoring saves ~$3,000 per year, but early termination fees of 1–3% of contracted monthly volume can erase that saving if your business changes course.

Key Terms
Spot Factoring
Factoring individual invoices on demand with no contract, no minimum volume, and no long-term commitment. Also called selective factoring; carries a fee premium of 0.5–1.5% per 30-day period over contract rates.
Contract Factoring
A factoring agreement — typically 12 months — committing you to factor all invoices from specified customers, or a minimum monthly volume. Offers lower per-invoice rates but may include termination fees of 1–3% of contracted monthly volume if you exit early.
Advance Rate
The percentage of an invoice’s face value you receive upfront. Typical advance rates run 80–97% for both spot and contract factoring; the remaining balance (minus fees) is released from the reserve when your customer pays.
Factoring Fee
The cost charged per billing period (usually per 30 days) on the invoice face value. Spot factoring fees run 0.5–1.5% higher per period than contract rates; the exact fee depends on customer creditworthiness, invoice size, and volume commitment.
Reserve Account
The portion of the invoice value held back by the factor until your customer pays. If your advance rate is 90%, the factor holds 10% in reserve; when the customer pays, the reserve (minus the factoring fee) is released to you.
Notice of Assignment
A notice sent to your customers when you factor their invoices, directing payment to the factor instead of you. Required in both spot and contract factoring; some customers may have assignment restrictions in their contracts, so verify before factoring.
Minimum Volume Commitment
The contractual floor on monthly invoice volume in a contract factoring agreement. If your actual volume falls below the minimum (e.g., $25,000/month), the factor charges a shortfall fee on the gap — even though you received no advance on the missing volume.
Which Should You Choose?
Choose spot factoring if: your invoice volume varies significantly month-to-month (seasonal businesses, project-based companies), you want to test a factor before committing to a 12-month agreement, you only need factoring 3–4 times per year, or you have a single large invoice you want to factor without entering an ongoing relationship. Spot factoring premium of 0.5–1.5% per period is cheaper than paying contract minimums in slow months.
Choose contract factoring if: you have consistent, predictable invoice volume above the minimum threshold ($10,000–$50,000/month depending on the factor), you want the factor to manage your entire accounts receivable (AR) function (invoicing follow-up, aging reports, collections), or you are in a high-growth phase where a committed funding partner at lower rates benefits you over a 12-month period. At $50,000/month in consistent volume, contract factoring saves ~$3,000/year vs. spot rates.
When Spot Factoring Makes Sense
Your invoice volume is inconsistent. Seasonal businesses, project-based companies, and businesses experiencing growth transitions often have months with $200,000 in invoices and months with $20,000. A 12-month contract with volume minimums becomes a cost burden in slow months. Spot factoring aligns cost with actual need.
You are evaluating a factor before committing. Spot factoring lets you test a factor’s technology, customer service, and collection practices on a few invoices before signing a 12-month agreement. This is particularly valuable when moving from one factor to another.
You only need factoring occasionally. If factoring bridges a gap 3–4 times per year rather than monthly, the spot premium is often cheaper than paying contract minimums 12 months per year.
You have one large invoice. A single $500,000 invoice from a creditworthy buyer is a natural spot factoring candidate — you are not in a factoring relationship permanently, you have a one-time liquidity need.
When Contract Factoring Makes Sense
Your invoice volume is consistent and predictable. A staffing agency factoring $80,000/month every month for 12 months will pay significantly less in total fees under a contract arrangement than at spot rates. The math is straightforward: at 0.75% per period savings × $80,000 × 12 months = $7,200 annual savings.
You need the factor to manage your entire AR function. Contract factoring typically includes full AR management — the factor handles invoicing follow-up, aging reports, and collections across your entire customer base. This operational benefit is often as valuable as the rate saving.
You are in a high-growth phase. If you are growing from $50,000 to $200,000 in monthly invoicing over a 12-month period, contract factoring with a volume floor gives you a guaranteed funding partner and often better rates at higher volumes.
Cost Comparison — Annual Fees
A business factors $50,000/month in invoices with 30-day customer payment.
| Spot Factoring | Contract Factoring | |
|---|---|---|
| Fee rate | 2.5% per 30 days | 2.0% per 30 days |
| Monthly fee | $1,250 | $1,000 |
| Annual fee | $15,000 | $12,000 |
| Annual saving | — | $3,000 |
| Flexibility | Full | Locked in for 12 months |
The $3,000 annual saving from contract factoring needs to be weighed against: the termination fee risk if circumstances change, the minimum volume fee if some months fall below the floor, and the value of flexibility if your business needs to pause factoring mid-contract.
| Metric | Spot Factoring | Contract Factoring |
|---|---|---|
| Invoice | $50,000, net-30, 90% advance | $50,000, net-30, 90% advance |
| Fee rate | 3.5%/30 days (no-contract premium) | 1.75%/30 days |
| Advance (90%) | $45,000 | $45,000 |
| Fee on $50,000 | $1,750 | $875 |
| Reserve (released when paid) | $3,250 | $4,125 |
| Contract commitment | None | 12-month, $25,000/mo minimum |
| Total Cost | $1,750 | $875 |
| Effective APR | ~42% | ~21% |
Cost difference per invoice: $875 cheaper with contract factoring. At $25,000/month over 12 months: ~$10,500 total savings vs. spot rates.
Frequently Asked Questions
Which factors offer spot factoring?
Spot factoring is less common than contract factoring. Providers offering genuine spot factoring (no contract, no minimums) include Riviera Finance (month-to-month available), Paragon Financial Group, and BlueVine (where factoring is available). Most large freight factors (eCapital, Triumph Business Capital, RTS Financial) require contracts with minimum volumes, though some offer spot at a premium. Always confirm spot availability and pricing directly — published rates are usually for contract arrangements.
What is a minimum volume fee?
Contract factoring agreements specify a minimum monthly volume (e.g., $25,000/month). If your actual factoring volume in a given month falls below this minimum, the factor charges a shortfall fee — typically the factoring fee on the difference between your actual volume and the minimum. A month where you factor only $10,000 against a $25,000 minimum could result in a fee on the $15,000 shortfall, even though you received no advance on it.
Can I switch from contract to spot factoring?
Yes, but you need to wait for your contract to end (or pay the termination fee). Most contract factoring agreements have a 30–90 day termination notice requirement. Some allow conversion to spot at the contract renewal date. If you are approaching a renewal, negotiate for spot or month-to-month terms rather than automatically renewing.
Is spot factoring available for freight?
Yes — RTS Financial is the largest freight factor with no minimum volume requirement and no long-term contract requirement for owner-operators. Other freight factors (Bobtail, some regional freight factors) also offer spot. eCapital and Triumph Business Capital require 12-month contracts with volume minimums and do not offer true spot factoring.
What is the difference between spot factoring and invoice financing on demand?
Spot factoring involves selling the invoice to the factor (the factor collects from your customer). Invoice financing on demand (like Fundbox's product) is a revolving line where you draw against outstanding invoices but retain the customer relationship and collection responsibility. Spot factoring is faster and qualifies based on customer creditworthiness; on-demand invoice financing is private (no customer notification) but requires your credit qualification.
