Invoice Factoring vs. Asset-Based Lending for Manufacturers
Both programs lend against the same collateral your shop already produces: receivables. Factoring buys them one invoice at a time. ABL lends against a pooled borrowing base of AR, inventory, and often equipment. The question is almost never which is better — it's when your shop crosses the line where ABL's lower rate finally outweighs its reporting overhead.
How each one actually funds
Factoring: you ship, you invoice, the factor verifies with your customer and advances 80–95% within a day. The customer pays the factor; the reserve releases minus the fee. ABL: a lender sets advance rates against eligible collateral — commonly 85% of AR under 90 days and 50–60% of inventory — and you draw against that availability like a revolver, submitting a borrowing base certificate weekly.
- Factoring funds per invoice; ABL funds against a pool
- Factoring closes in 1–2 weeks; ABL takes 6–10 weeks plus a field exam
- Factoring underwrites your customers; ABL underwrites your collateral and your controls
Cost, honestly compared
Factoring runs 1.5%–3.5% of invoice face value per 30 days. ABL prices at roughly SOFR + 2%–5% APR, plus unused-line fees and field exam costs of $8,000–$25,000 a year. At $2M+ in average borrowings, ABL is typically a third to a half the all-in cost of factoring the same receivables. Below about $1M in borrowings, the exam and reporting costs eat the rate savings and factoring wins on a net basis.
Reporting: the part shops underestimate
Factoring asks for weekly AR aging and clean proof of delivery. ABL asks for a weekly borrowing base certificate, monthly financials with AR and AP aging, quarterly compliance certificates, and reviewed or audited statements at larger facility sizes. If nobody in the shop owns that calendar, an ABL facility becomes a covenant problem rather than a cheaper line.
- Factoring: weekly AR aging, no covenants, no field exams
- ABL: weekly borrowing base, springing fixed charge coverage (often 1.10×–1.25×), annual field exam
Scalability and the transition point
Factoring scales automatically — more invoices, more funding, no renewal conversation. ABL scales in steps: availability is capped by the borrowing base and the facility size you negotiated, so growth spurts can outrun it between amendments. Most manufacturers we refer are best served by factoring from roughly $500k to $15M in revenue, then move to ABL once revenue clears $10M–$15M with a controller producing monthly financials on time.
How the handoff works
We refer factoring requests to partners whose contracts don't lock you in and who will hand the file cleanly to an ABL lender when you graduate. A year of disciplined AR reporting under a factor is the single best preparation for ABL underwriting — the diligence file is largely already built.
