Invoice Factoring for Small Business
Invoice factoring turns unpaid B2B invoices into same-week cash. You sell the invoice to a factoring company for 80–95% of face value, they collect from your customer, and you get the balance minus a fee. It's built for small businesses whose customers pay net-30, net-60, or net-90 while payroll, materials, and fuel bills won't wait. Because factors underwrite your customers' credit instead of yours, personal FICO barely matters — making factoring one of the easier alternative funding options to qualify for. Below: how it works, what it costs, and construction-specific rules.
How invoice factoring works
- 1. Submit an invoice. You send the factor a copy of the unpaid B2B invoice.
- 2. Get an advance. Within 1–5 days the factor wires you 80–95% of face value.
- 3. Factor collects. Your customer pays the factor directly (Notice of Assignment redirects payment).
- 4. Reserve released. Once the invoice clears, the factor sends you the remainder minus the fee (typically 1–5% per 30 days outstanding).
Factoring vs. other cash-flow options
| Product | How it works | Typical cost | Speed | Best for |
|---|---|---|---|---|
| Invoice factoring | Sell the invoice; factor collects | 1–5% per 30 days | 1–5 days | B2B with slow-paying customers |
| Invoice financing | Borrow against invoices; you collect | 0.5–4% per 30 days | 1–5 days | Owners who want to keep collections in-house |
| Business line of credit | Revolving credit you draw as needed | 10–60% APR | 1–7 days | Ongoing, unpredictable cash-flow gaps |
| Merchant cash advance | Cash repaid from card sales | 1.20–1.50 factor | 24–48 hours | Retail/restaurants, no invoices |
Construction invoice factoring
Construction is a specialty within factoring. Progress billing, retainage, lien waivers, and pay-when-paid clauses make construction receivables harder to fund than a straightforward net-30 invoice — but factors that specialize in the industry will absolutely finance them. Expect advance rates closer to 70–85% (vs 80–95% for standard receivables) to leave room for disputes and retention.
Progress billings
Factors will fund AIA G702/G703 progress payments once architect-approved and signed by the GC.
Retainage
The 5–10% retention held until project completion is typically not advanced up-front — some factors will fund it separately at higher cost.
Lien waivers
You'll sign conditional and unconditional lien waivers with each draw; the factor needs assurance it isn't subordinate to a mechanic's lien.
Pay-when-paid
If your contract subordinates payment to the owner paying the GC, factors will price for that added risk (or decline).
Subcontractor factoring
Common play: subs factor GC-owed invoices to keep payroll and material bills current while waiting 60–90 days on the GC.

Frequently asked questions
What is invoice factoring for small business?
You sell an unpaid B2B invoice to a factoring company for 80–95% of face value up-front. The factor collects from your customer and remits the remainder minus a fee (usually 1–5% per 30 days outstanding).
What's the difference between recourse and non-recourse factoring?
With recourse factoring, you buy the invoice back if your customer doesn't pay — cheaper but riskier. Non-recourse shifts customer credit risk to the factor, at a higher fee. Most small business factoring is recourse.
How do I qualify?
Factoring cares about your customers' creditworthiness, not yours. You need B2B (not consumer) invoices, clean receivables (no liens), and typical net-30 to net-90 terms. Personal FICO is rarely a gating factor.
How much does invoice factoring cost?
Discount rates run 1–5% per 30 days invoice outstanding. A 90-day invoice at a 2% monthly rate costs ~6% of face value. Advance rates typically 80–95%; construction is closer to 70–85%.
Can construction companies factor invoices?
Yes, but it's a specialty. Progress billing, retainage, lien waivers, and pay-when-paid clauses make construction receivables harder to fund. See the construction section below.
Will my customers know I'm factoring?
In notification factoring (the standard), yes — the factor sends a Notice of Assignment and payments are redirected. Non-notification factoring exists but is rare and priced higher.
