Merchant Cash Advance vs Invoice Finance UK 2026: Which Fits Your Business?
A merchant cash advance is repaid automatically as a percentage of daily card sales, suited to retail and hospitality businesses. Invoice finance advances cash against unpaid B2B invoices, suited to businesses with longer customer payment terms. Here is how the two compare for 2026.
TL;DR - 30-Second Summary
- - Merchant cash advance: repaid as a share of daily card sales, suited to consumer-facing, card-heavy businesses
- - Invoice finance: advances cash against unpaid B2B invoices, suited to businesses with 30-90 day payment terms
- - Choose based on how you get paid: card transactions point to MCA, business invoices point to invoice finance

What Is a Merchant Cash Advance?
A merchant cash advance provides an upfront lump sum in exchange for an agreed percentage of future card sales, automatically collected by the card payment processor until the advance (plus a fixed fee, expressed as a factor rate rather than an APR) is repaid. Because repayments are proportional to turnover, they rise in busy periods and fall in quiet ones, which many card-heavy, seasonal businesses find easier to manage than a fixed monthly loan repayment.
What Is Invoice Finance?
Invoice finance releases cash tied up in unpaid B2B invoices, advancing typically 80-90% of the invoice value shortly after it is raised, with the remainder (minus fees) paid once the customer settles. It solves the cash flow gap created by offering customers 30, 60 or 90-day payment terms, letting a business access money it has effectively already earned, rather than waiting for the full payment cycle to complete.
Who Should Choose What?
Choose a merchant cash advance if...
- - Most of your revenue comes through card payments
- - Your turnover is seasonal or variable
- - You want repayments to flex automatically with sales
- - You need funds quickly without a lengthy application
Choose invoice finance if...
- - You invoice other businesses on credit terms
- - Cash is tied up for 30-90 days waiting for payment
- - You want a facility that scales with your sales ledger
- - You want a more traditional cost-of-borrowing structure
Frequently Asked Questions
What is a merchant cash advance?
A merchant cash advance (MCA) provides a lump sum to a business in exchange for an agreed share of future card sales, automatically deducted at source by the card payment provider until the advance (plus a fixed fee) is repaid. Repayments flex with turnover — busier periods repay faster, quieter periods repay more slowly — making it popular with retail, hospitality and other card-sales-heavy businesses.
What is invoice finance?
Invoice finance advances cash against unpaid B2B invoices, typically 80-90% of the invoice value within a day or two of raising it, with the remaining balance (minus fees) paid once the customer settles. It is suited to businesses that invoice other businesses on credit terms (commonly 30-90 days) rather than taking payment at the point of sale.
Which businesses can access a merchant cash advance?
Merchant cash advances are aimed at businesses with a steady volume of card transactions — retailers, restaurants, salons, and similar consumer-facing businesses — since the repayment mechanism depends on a card payment processor being able to automatically deduct a percentage of each transaction.

Which businesses can access invoice finance?
Invoice finance suits B2B businesses that issue invoices with payment terms, such as manufacturers, wholesalers, recruitment agencies and professional services firms, where cash is tied up between delivering the work or goods and being paid weeks later.
How is the cost of each typically structured?
A merchant cash advance typically charges a fixed factor rate (for example, repay £1.30 for every £1 advanced) rather than a traditional interest rate, which can make the effective annualised cost high, especially if repaid quickly. Invoice finance combines a discount/interest charge on the advance with a service fee, generally more comparable to a traditional cost-of-borrowing structure.
Which is faster to arrange?
Both can be arranged quickly compared with a bank loan, often within days, since both rely heavily on automated data (card transaction history for MCA, sales ledger data for invoice finance) rather than lengthy manual underwriting.
Does either require the business to have existing customer invoices?
Invoice finance specifically requires B2B invoices with payment terms to advance against — it is not usable by a business that takes payment upfront at the point of sale. A merchant cash advance requires the opposite: consistent card payment turnover, and is not typically suitable for businesses that mostly invoice other businesses on credit.
Can repayments become unaffordable with either option?
With a merchant cash advance, repayments automatically scale down in quiet periods since they are a percentage of turnover, which can help cash flow but also means the advance takes longer to clear if sales are weak. With invoice finance, if a large customer becomes slow to pay or defaults, and the facility is recourse, the business must still repay the advance from other funds, which can create a cash flow strain of its own.
