Invoice Financing and Factoring: How to Turn Receivables into Working Capital
How invoice financing and factoring work, the difference between the two, what they cost, and when they’re the right tool for your cash flow situation.
For businesses that invoice other businesses — contractors, staffing firms, trucking companies, wholesalers, manufacturers, professional services firms — accounts receivable represents money earned but not yet received. A business with $300,000 in outstanding invoices is profitable on paper but potentially cash-poor in practice, particularly if customers pay on Net-30 to Net-60 terms.
Invoice financing and factoring are tools specifically designed to convert outstanding receivables into immediate working capital — without waiting for customers to pay.
The Accounts Receivable Cash Flow Problem
The AR timing gap is one of the most common cash flow challenges in B2B businesses. The sequence is familiar:
- You deliver a product or complete a service
- You issue an invoice with 30, 45, or 60-day payment terms
- Your costs — labor, materials, overhead — are due now
- Payment arrives 30–60+ days later
During that 30–60 day gap, you’re financing your customers’ operations out of your own cash reserves. The faster you grow, the more acute this problem becomes — because rapid growth means more invoices outstanding, more capital tied up in AR, and more pressure on cash.
What Is Invoice Financing?
Invoice financing (also called accounts receivable financing or AR financing) is a loan or line of credit that uses outstanding invoices as collateral. You retain ownership of your receivables — you collect from your customers directly, and you use the invoice value to secure a credit facility.
The lender advances 80–90% of eligible invoice value as a revolving line of credit. You draw against your outstanding invoices, repay as customers pay you, and draw again as new invoices are issued. Your customers typically don’t know about the financing arrangement — it’s confidential.
Invoice financing is most similar to a secured line of credit — the invoices are the collateral, and you’re paying interest on what you draw. It requires more underwriting than simple working capital products but offers larger credit lines and lower costs than most unsecured working capital options.
What Is Invoice Factoring?
Invoice factoring is fundamentally different from invoice financing. In factoring, you sell your invoices to the factoring company (the “factor”) at a discount. The factor advances you 70–90% of the invoice face value immediately, then collects directly from your customer when the invoice is due. When the customer pays, the factor remits the remaining balance minus their fee.
The key distinction: in factoring, the factor owns your receivable and collects from your customer directly. This means your customers know you’re using a factoring arrangement — the factor’s name appears on payment instructions, not yours.
Advance rate: 85% = $42,500 advanced immediately
Factoring fee: 3% of invoice ($1,500)
Reserve held: 15% = $7,500
Customer pays in 30 days.
You receive: $7,500 reserve − $1,500 fee = $6,000
Total received: $42,500 + $6,000 = $48,500
Cost: $1,500 on a $50,000 invoice
Invoice Financing vs. Factoring: Key Differences
General guideline: Invoice financing is preferable if customer relationships are sensitive and you want to maintain direct payment collection. Factoring is preferable for speed, accessibility, and situations where your customers’ creditworthiness is stronger than your own business profile.
How to Calculate the Real Cost
Invoice Financing Cost
Invoice financing is typically priced as an annual percentage rate (APR) on the drawn balance, often ranging from 15–35% APR for alternative lenders. If you draw $100,000 against invoices for 30 days at 20% APR, the monthly cost is approximately $1,667.
Factoring Cost
Factoring is priced as a percentage of the invoice face value — typically 1–5% per 30-day period. A 3% factoring fee on a $50,000 Net-30 invoice costs $1,500. If the customer is slow to pay and the invoice ages to 60 days, fees may compound — understand how the pricing escalates for slow-paying customers before signing a factoring agreement.
Converting factoring fees to APR: a 3%/30-day fee is approximately 36% APR. This sounds high — but for specific invoice gaps where the capital need is defined and temporary, factoring often makes more economic sense than an open-ended working capital loan.
Who Qualifies for Invoice Financing and Factoring?
Invoice Financing Qualification
- 6+ months in business
- 600+ personal credit score (varies by lender)
- $10,000–$25,000+ in monthly B2B invoicing
- Customers must be creditworthy businesses or government entities
Factoring Qualification
Factoring qualifies based heavily on the creditworthiness of your customers — not your own credit profile. This makes factoring particularly accessible for:
- Newer businesses with limited credit history
- Businesses with lower personal credit scores
- Businesses whose primary customers are large, creditworthy companies or government agencies
- Trucking, staffing, construction, and manufacturing companies — industries with predictable B2B billing patterns
The critical factor: your customers must be creditworthy, commercial entities that will actually pay. Consumer receivables, disputed invoices, and invoices with complex payment terms are less factorable.
