Invoice Finance vs Merchant Cash Advance - What's the Difference?
Invoice finance advances cash against your unpaid B2B invoices. Merchant cash advances provide a lump sum repaid as a percentage of daily card takings. Invoice finance suits B2B businesses invoicing on credit. MCAs suit retail, hospitality, and e-commerce businesses taking card payments.
Why This Matters
Choosing the wrong funding type can cost UK SMEs thousands in unnecessary fees or restrict cash flow when it matters most. Invoice finance and merchant cash advances solve fundamentally different problems for different business models. Invoice finance releases cash tied up in outstanding B2B invoices, typically advancing 80-90% within 24 hours against invoices from creditworthy customers. It suits businesses invoicing other companies on 30-90 day terms. Merchant cash advances (MCAs), by contrast, provide upfront capital repaid automatically through a fixed percentage of daily card or terminal takings. MCAs work for businesses with consistent card revenue but no invoices to fund against. The cost structures differ drastically. Invoice finance charges service fees around 0.3-1.5% of invoice value plus interest on funds advanced (typically 1-3% over base rate). MCAs quote a factor rate, often 1.2-1.5, meaning a £50,000 advance costs £60,000-£75,000 to repay regardless of how quickly you repay it. Confusing the two leads to retail businesses applying for invoice finance they cannot access, or B2B firms accepting MCA terms that can exceed 40-80% APR equivalent. Understanding which model fits your revenue structure and repayment capacity is critical before committing to either.
Key Points
- Invoice finance is secured lending against B2B invoices, typically advancing 80-90% of invoice value within 24 hours, with the balance released (minus fees) when your customer pays.
- MCAs are not loans but purchase agreements. A provider buys a percentage of future card sales at a discount, typically 1.2-1.5x the advance (so £50,000 advanced costs £60,000-£75,000 total).
- Invoice finance costs typically range from 0.5-2% monthly equivalent (including service fees and interest), while MCAs can equate to 40-80% APR or higher depending on repayment speed.
- Eligibility differs fundamentally: invoice finance requires B2B invoices from creditworthy debtors (often minimum £5,000-£10,000 monthly turnover), while MCAs require minimum monthly card takings (typically £5,000-£10,000).
- Repayment flexibility favours invoice finance. You control when invoices are raised and can reduce usage. MCAs auto-deduct 10-20% of daily card revenue until the fixed total is repaid, impacting cash flow during quiet periods.
- Invoice finance from providers like Close Brothers or Bibby Financial Services typically requires personal guarantees but is asset-backed. MCAs from commercial lenders are unsecured but carry higher effective costs.
- Regulatory status: invoice finance providers offering credit are usually FCA authorised. Many MCA providers operate outside FCA perimeter as they are not providing credit in the regulatory sense, offering less consumer protection.
Real-World Example
A Leeds graphic design agency invoices £80,000 monthly to corporate clients on 45-day terms versus a Brighton coffee shop taking £40,000 monthly in card payments
The design agency uses invoice discounting from Aldermore, advancing 85% (£68,000) of invoices immediately at 1.2% monthly cost (roughly £816). They maintain client relationships as the facility is confidential. The coffee shop, having no invoices, uses an MCA advancing £30,000 repaid at 1.35 factor rate (£40,500 total). With 15% daily retrieval rate, they repay £6,000 weekly from card takings, clearing the advance in 7 weeks but paying £10,500 in fees (equivalent to approximately 67% APR). Each chose correctly for their revenue model, but the coffee shop pays significantly more for speed and convenience.
Common Pitfalls
- Retail or hospitality businesses applying for invoice finance when they have no B2B invoices. Providers like Sonovate or Pulse Cashflow need qualifying receivables, not card sale projections.
- B2B businesses accepting MCAs because approval is faster, then discovering daily card deductions cripple cash flow when most revenue comes via bank transfer invoices not processed through card terminals.
- Misunderstanding MCA factor rates as interest rates. A 1.3 factor is not 30% APR. If repaid over 6 months it equates to approximately 60% APR, over 3 months closer to 120% APR.
- Assuming invoice finance is cheaper in all cases. For very short-term needs (under 4 weeks) on small amounts, the setup and service fees can exceed MCA costs, though this is rare.
- Stacking multiple MCAs or invoice facilities without understanding cross-default clauses. Many agreements prohibit taking additional funding, risking immediate repayment demands.
What to Do Next
- List your revenue sources for the last 3 months. If over 70% comes from B2B invoices on credit terms, investigate invoice finance from Bibby Financial Services, Close Brothers, or Skipton Business Finance.
- If over 60% of revenue is card or terminal payments with minimal B2B invoicing, request MCA quotes and calculate the true APR equivalent by dividing total repayment cost by advance, then adjusting for repayment period.
- For hybrid businesses (both invoices and card sales), consider selective invoice finance on your largest invoices while maintaining cash reserves from card sales, or use a specialist like Novuna Business Finance who understand mixed revenue models.
- Request illustrations showing monthly cash flow impact. For invoice finance, model 85% advance on typical invoices minus monthly fees. For MCAs, calculate daily retrieval amount (advance × factor rate × daily percentage) and confirm your business can sustain that deduction during slower trading days.
Related Questions
Can I use invoice finance if I also take card payments?
Yes, absolutely. Invoice finance providers like Ultimate Finance or IGF Invoice Finance only fund against qualifying B2B invoices. Your card payment revenue is irrelevant to the facility. Many agencies, wholesalers, and contractors use invoice finance while also taking occasional card payments for smaller jobs.
Are merchant cash advances regulated by the FCA?
Most MCAs fall outside FCA consumer credit regulation because they are structured as purchase agreements for future receivables, not loans. This means no access to Financial Ombudsman Service for disputes. Always check provider authorisation status and understand your recourse before signing.
Which is faster to access, invoice finance or an MCA?
MCAs are typically faster for initial approval, often 48-72 hours with minimal paperwork. Invoice finance facilities from providers like Hydr or Triver take 5-10 working days for first setup including credit checks on your customers, but subsequent advances are same-day once the facility is live.
Can I switch from an MCA to invoice finance later?
Yes, if your business model changes to B2B invoicing. You must fully repay the existing MCA first, as invoice finance providers like Secure Trust Bank will not advance against invoices if revenues are already pledged to an MCA provider. Some brokers can structure this transition.
