Merchant Cash Advance — eligibility, lenders, and how it works in the UK

In short

A merchant cash advance (MCA) is a lump-sum advance repaid by an agreed share of future card or platform sales — typically split daily or weekly from the payment processor — until a fixed total is settled. The total is set by a factor rate (for example 1.20 means repay £12,000 on a £10,000 advance), not an APR. It typically suits UK retail, hospitality and online merchants that take card payments through a terminal, payment processor or marketplace and need working capital that flexes with trading rather than a fixed monthly instalment. Funding can range from around £500 to £1m, decisions often rely on transaction data rather than full accounts, and a director personal guarantee is the norm at SME ticket sizes. It is rarely suitable for purely B2B businesses paid by bank transfer, very low card volumes or sectors many lenders restrict. Approval and pricing are subject to lender underwriting and the quality of the card-sales feed shared with the provider.

How merchant cash advance works in plain English

Merchant cash advance providers underwrite primarily against payment data — the value, consistency and seasonality of card, point-of-sale or platform sales. Rather than a monthly instalment, the business agrees a fixed total to repay (calculated from the advance and a factor rate) and a holdback percentage. Settlement is then taken automatically from the card processor, usually as a daily or weekly split, until the agreed total is cleared. Quieter trading weeks mean smaller deductions; busier weeks repay faster.

Pricing is expressed as a factor rate (commonly 1.10 to 1.50 in the UK market) rather than an APR. A 1.30 factor on £20,000 means a total repayable of £26,000 regardless of how long that takes — so the effective annualised cost rises sharply if repayment is fast and falls if trading slows. Because MCAs are not structured as loans, the Consumer Credit Act and APR disclosure regime do not apply. The honest comparison against a term loan is on total cost, expected repayment window and flexibility, not on headline rate alone.

MCAs are often used for short-term working capital, stock purchases, refit costs, marketing pushes and seasonal cashflow gaps. They are less suitable for fixed long-term commitments like property purchases or large equipment buys, where asset finance or a term loan usually fits better. UK underwriting typically focuses on 3-12 months of card-sales history, average monthly takings and the absence of significant chargebacks or recent restructures. Providers integrated with platforms such as Square, SumUp, Shopify, PayPal or Worldpay can pre-approve facilities directly from the merchant data they already see. Where the business does not yet have card sales, an MCA is unlikely to be the right route.

A personal guarantee (PG) from a director is the norm at SME ticket sizes — although the advance itself is unsecured against company assets, the PG means a director shares responsibility if the business cannot complete the repayment. MCAs differ from revenue-based finance in two important ways: MCAs settle from card-processor takings (so card sales drive it), while RBF typically settles by direct debit against a wider revenue picture from connected platforms and banking data; and MCAs are structured as a purchase of future receivables, while many RBF products are structured as loans with FCA-relevant disclosures.

Best-fit business profile

Retail, hospitality, personal services, merchants with card/payment data.

Core eligibility signals

Most UK lenders in this category look for a combination of the following. Individual lender criteria vary and final approval is subject to lender underwriting.

• Meaningful card/POS/platform volume
• working-capital need
• Consistent monthly card or platform sales — typically £5k+ per month, depending on provider.
• Several months of trading data the lender can read directly from the payment processor.
• B2C or merchant-led sales mix where most customers pay by card or through a marketplace.
• A clean payment history without large recent chargeback spikes or processor disputes.

Common blockers

Where the following apply, lenders in this category may decline or deprioritise the application.

• No payment volume
• not on required platform
• low sales
• restricted sector
• Business invoices customers by bank transfer rather than taking card payments.
• Recent material drop in card sales or a seasonal trough at the point of underwriting.
• Sector restrictions — adult, gambling, regulated firearms, some crypto activity.
• Multiple existing advances stacked on the same card feed.

What underwriters typically look at

• Average monthly card or platform takings over the last 6-12 months.
• Sales trend — stable, growing or declining — and how seasonal the business is.
• Number of separate card processors and whether the lender can integrate with each.
• Chargeback ratio, refund frequency and any recent processor restrictions.
• Existing MCA stacking and remaining balances with other providers.
• Director credit profile on larger facilities, even where the advance is unsecured.

Documents typically requested

Expect to provide most of the following. Individual lenders may ask for more, depending on the size and structure of the facility.

• Last 3-6 months of merchant or platform statements (Stripe, Square, Worldpay, Shopify, PayPal).
• Last 3-6 months of business bank statements.
• Photo ID and proof of address for the director or owner.
• Companies House details or sole-trader information.
• Details of any existing finance facilities or advances.

Watch-outs — cost and regret risk

Honest cautions on this product. None of these are reasons to avoid it automatically — they are the questions to settle before signing. This is educational guidance, not financial advice.

• Factor rate ≠ APR. A 1.30 factor on a 6-month expected repayment is roughly equivalent to a 50%+ APR on a term loan — compare total cost, not headline numbers.
• Stacking multiple advances on the same card feed is a common regret. Holdbacks combine and can starve day-to-day cashflow.
• Repaying early does not usually save money — the fixed total is owed regardless of how fast it clears.
• If card takings fall sharply, the lender may switch to a fixed direct-debit top-up to keep repayment on track. Check the contract for this clause.
• Personal guarantee means a director is personally on the hook if the business cannot complete the advance. Read the PG wording before signing.
