MCA vs receivables purchase (also called factoring or accounts-receivable financing) is the cleanest legal-economic comparison in alternative business finance — they both involve a funder paying cash today for future receivables, but the structure, pricing, recourse, and regulatory treatment differ dramatically. Conflating them costs merchants meaningful money and operational flexibility.
The mechanics — what each product actually buys.
MCA (merchant cash advance): 1. Funder buys an undefined slice of future revenue — "the next $130K of receivables, defined as X% of total deposits or card volume." 2. No specific invoices identified; no payor identified. 3. Repayment continues until total RTR is collected, regardless of which customer revenue produced it. 4. Term is variable (depends on revenue velocity). 5. Personal guarantee + UCC-1 typically required.
Receivables purchase (factoring): 1. Funder buys specific named invoices — "Invoice #4521 to Acme Corp for $50K, due in 45 days." 2. Each invoice underwritten on the payor's creditworthiness (not just merchant's). 3. Repayment occurs when the specific payor pays the specific invoice. 4. Term is defined by invoice payment terms (typically 30-90 days). 5. Notice of assignment sent to payor; payor pays the factor directly.
The math — pricing comparison. $100K of capital needed by a merchant with $400K of outstanding invoices to creditworthy commercial customers (Net-30 to Net-60):
MCA path: - Advance: $100K, factor 1.32 → $132K RTR - 8-month payoff at $600/day debit - Cost of capital: $32K on $100K = 32% over 8 months → annualized ~48% effective - Total cost on $100K: $32K
Factoring path: - Sell $130K of invoices to factor at 80% advance rate → $104K upfront - Factor fee: 2.5% for first 30 days + 0.75%/week after - Average payment period: 45 days → fee ~4% of face value → $5.2K - Final reserve release on payment: $130K − $104K advance − $5.2K fee = $20.8K residual to merchant - Total cost on $104K of capital deployed: $5.2K → annualized ~17% effective - Total cost on $104K: $5.2K
The factoring path is dramatically cheaper — by ~$27K — IF the merchant has eligible invoices to creditworthy commercial payors.
The strategic insight — when each is the right tool.
MCA is right when: 1. Revenue is consumer-paid (restaurants, retail, services) — no invoices to factor. 2. Speed matters more than cost (24-48 hours vs 5-10 day factor onboarding). 3. Invoices are to non-creditworthy or unverifiable payors. 4. The need is one-time and small ($25-150K). 5. Merchant doesn't want customers notified that financing is being used.
Factoring is right when: 1. Revenue is B2B with clear invoices to creditworthy commercial payors. 2. Capital need is recurring (ongoing receivables financing, not one-time injection). 3. Cost matters more than discretion (factoring is materially cheaper). 4. Merchant can tolerate notice-of-assignment going to customers. 5. Capital need scales with sales (factor line auto-grows with invoice volume).
The mechanics — recourse difference.
MCA: Typically full recourse to the business + personal guarantee. Funder bears no payor risk because no specific payor is identified — repayment comes from revenue regardless of source.
Factoring: Two flavors. Recourse factoring: if the named payor doesn't pay within X days (typically 90), the merchant must buy the invoice back. Non-recourse factoring: factor bears the payor credit risk — if payor goes bankrupt or refuses to pay, the loss is the factor's. Non-recourse pricing is higher (typically 1-2% additional fee).
The mechanics — regulatory treatment.
MCA: Operates in a gray zone — defended legally as a true purchase of receivables not subject to lending laws, increasingly challenged in states with new disclosure rules. No federal licensing required.
Factoring: Long-established as a non-lending product because each transaction is the purchase of a specific identifiable asset (an invoice). Not subject to most state lending laws. Some states (CA, NY, GA) have factor-licensing regimes but they're light compared to commercial lending licensing.
The strategic insight — operational reality. Factoring requires meaningful operational infrastructure:
- Invoice quality. Factors will not buy invoices to deadbeat or related-party payors.
- Notice of assignment. Customers receive a letter telling them to pay the factor directly. Some merchants find this awkward; established factoring relationships normalize it.
- Verification calls. Factors typically call payors to verify the invoice is valid and undisputed. Adds friction for the merchant's customer relationship.
- Reserve mechanics. Factor typically advances 70-90% of invoice face value, holds the residual as a reserve until the payor pays — meaning cash flow is in two waves, not one lump sum.
MCAs require almost zero operational infrastructure — sign FRSA, daily ACH starts, done.
The honest framing. A B2B merchant with creditworthy customer payors who chooses MCA over factoring is paying 2-3x the cost of capital for what is effectively a worse-structured product. The reason it happens is that MCA brokers outsell factoring brokers in volume and prominence — most merchants never hear factoring as an option. The merchant who maps their revenue type (B2B invoiced vs consumer-paid) and capital need (one-time vs recurring) against the two products consistently lands on the cheaper, better-fit answer.
Related terms
- Invoice factoring — Invoice factoring is selling your unpaid invoices to a factoring company for immediate cash (typically 80-95% of invoice value). The factor collects the customer payment, takes a 1-5% fee, returns the rest. Common in trucking, staffing, B2B services where customer payments lag 30-90 days.
- Merchant cash advance (MCA) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan.
- Revenue-based financing (RBF) — Revenue-based financing (RBF) advances capital in exchange for a fixed percentage of future revenue until a multiple of the principal is repaid. No equity, no interest rate. Popular for SaaS (Capchase, Pipe), e-commerce (Wayflyer, Clearco), and processor-embedded products (Stripe Capital, Shopify Capital).
- MCA vs loan (legal distinction) — An MCA is legally a purchase of future receivables, not a loan. This distinction exempts MCAs from state usury caps but requires specific contract structure — including reconciliation provisions.
- Business funding options compared — The 2026 small business funding stack: SBA loans (cheapest, slowest), bank term loans + LOCs (cheap, slow, strict credit), fintech term loans + LOCs (medium cost, faster), invoice factoring (medium, AR-secured), equipment financing (medium, asset-secured), MCAs (most expensive, fastest, loosest credit).
- Working capital — Working capital is the cash a business uses to cover day-to-day operations — payroll, inventory, rent, utilities. Calculated as current assets minus current liabilities. Most MCA + LOC products are positioned as working-capital financing.
