MCA vs Invoice Finance: Which Suits Your Cash Flow
Merchant cash advance and invoice finance both release cash quickly, but they work on different mechanics. MCA advances a lump sum repaid as a fixed percentage of card takings; invoice finance releases a percentage of unpaid invoices, repaid when the customer pays. The right choice depends on how your business gets paid.
How merchant cash advance works
Merchant cash advance (MCA) provides a lump sum against future card sales, repaid automatically as a fixed percentage of daily or weekly card takings rather than a set monthly instalment. It suits businesses with strong, regular card turnover, such as retail, hospitality and salons, where sales volume varies week to week.
Because repayment tracks actual card revenue, quieter weeks mean smaller deductions and busier weeks mean faster repayment. There is no fixed term in the traditional loan sense; the advance is cleared once the agreed total (the advance plus the factor rate cost) has been collected through the card terminal provider.
How invoice finance works
Invoice finance releases a percentage, typically 70-90%, of the value of unpaid B2B invoices, with the balance (minus fees) paid once the customer settles. It suits businesses that sell to other businesses on credit terms, such as wholesalers, manufacturers and recruitment agencies, where cash is tied up waiting for 30, 60 or 90-day payment terms.
Two main structures exist: factoring, where the lender manages collections directly with your customers, and invoice discounting, where you retain control of collections and the arrangement stays confidential. The facility usually revolves, so as new invoices are raised and old ones are paid, funding availability refreshes.
The key mechanical difference
The core difference is what each product is repaid against: MCA tracks card sales revenue, invoice finance tracks the settlement of specific invoices. A business with no card terminal, such as a B2B manufacturer invoicing on 60-day terms, has nothing for MCA to attach to. A business with no unpaid invoice ledger, such as a café taking mostly card payments, has nothing for invoice finance to advance against.
This means the two products are rarely direct alternatives for the same business; the underlying revenue model usually decides which one is even available, before cost or preference come into it.
Cost and how it is calculated
MCA cost is expressed as a factor rate, commonly 1.1 to 1.4, applied once to the advance rather than compounding daily like an APR-based loan; a £20,000 advance at 1.2 means £24,000 collected in total. Invoice finance cost is usually a service fee (a percentage of invoice value) plus a discount fee (an interest-style charge on funds drawn), so the true cost depends on how quickly customers pay.
Neither figure compares cleanly to a bank loan APR, which is why lenders are required to show the total repayable amount alongside the rate, so businesses can compare the actual cash cost rather than headline percentages.
Eligibility and how fast each pays out
MCA eligibility centres on card transaction history, usually three to six months of processor statements, with limited emphasis on credit score, making it accessible to businesses with a recent adverse credit event. Invoice finance eligibility centres on the quality and spread of the debtor book, meaning a concentrated ledger with one or two large customers can be harder to fund than a spread of smaller invoices.
Both can complete faster than a term loan; MCA offers are frequently issued within 24 to 48 hours of processor data being reviewed, while invoice finance facilities typically take one to two weeks to set up but then release funds against new invoices within a day or two once live.
Which businesses each product suits
MCA tends to suit consumer-facing, card-heavy businesses needing short-term working capital for stock, equipment or a seasonal cash flow gap, where the automatic percentage-based repayment matches naturally fluctuating trade. Invoice finance tends to suit B2B businesses growing faster than their cash conversion cycle allows, where the gap between delivering work and getting paid is the actual constraint on taking on new orders.
A business that has both card and invoice revenue streams, such as a trade supplier with a small retail counter, may in principle qualify for either, and in that case the decision usually comes down to which revenue stream is larger and more predictable.
Deciding which to apply for
Start from how your customers pay you, not from the headline cost of either product, since that determines which one is structurally available before pricing matters. Map the actual gap: a card-sales business with a short-term stock or equipment need points towards MCA, while a B2B business with invoices sitting unpaid for weeks points towards invoice finance.
A broker can run both routes against the same lender panel simultaneously, so a like-for-like comparison of the total repayable amount is possible before committing to either product.
| Feature | Merchant cash advance | Invoice finance |
|---|---|---|
| Repaid against | Card sales revenue | Customer invoice payments |
| Repayment method | Fixed % of daily/weekly card takings | Deducted when invoice is settled |
| Typical cost structure | Factor rate (e.g. 1.1 to 1.4) | Service fee + discount fee |
| Speed to funds | 24 to 48 hours common | 1 to 2 weeks to set up, then fast per invoice |
| Best suited to | Card-heavy, consumer-facing trade | B2B trade on credit terms |
| Security typically required | Personal guarantee, card terminal assignment | Charge over the debtor book |
Step-by-step
- Identify how the majority of your revenue arrives: card payments or invoiced credit terms
- Gather the matching evidence: 3-6 months of card processing statements, or a current aged debtor list
- Establish the size of the actual gap you need to fund and over what period
- Compare total repayable amount across both routes, not just the headline rate
- Apply through a broker who can run both product types against the same lender panel
Example
A limited company running a small chain of cafes, which also supplies wholesale pastries to three local hotels on 30-day terms, needed £15,000 to cover a seasonal stock build. Its card takings were strong but its wholesale invoices were unpaid for weeks at a time. A broker compared an MCA against the card turnover with an invoice finance facility against the hotel invoices; the MCA cleared faster and matched the seasonal need.
Frequently asked questions
Can a business use both MCA and invoice finance at the same time?
In principle yes, since they draw against different revenue streams, but most lenders will want to understand the total borrowing position and how each facility is secured before approving a second product. It is more common for a business to use one or the other, then move to the second facility later as needs change.
Which is cheaper, MCA or invoice finance?
Neither is uniformly cheaper; it depends on the specific factor rate offered against your card turnover versus the service and discount fees offered against your invoice ledger. The only reliable comparison is the total amount repayable in cash terms for the funding period you need, which a broker can obtain from both types of lender.
Does a partnership of 4 or an LLP qualify for either product?
Yes, limited companies, LLPs and partnerships of 4 or more can be assessed for both MCA and invoice finance through FundBiz. Sole traders and smaller partnerships sit outside FCA-regulated introducer permissions and are directed elsewhere.
What happens to invoice finance if a customer pays late?
The facility is designed around this; funds already advanced are not clawed back simply because a payment runs late, though prolonged non-payment or disputed invoices can affect future availability against that customer. Persistent late payment across the ledger may also affect the advance rate offered at renewal.
Is a personal guarantee required for MCA?
Many MCA lenders ask for a personal guarantee from a director, alongside assignment of the card terminal takings, since the advance is unsecured against business assets in the way a mortgage or asset finance agreement would be. Terms vary by lender, so this should be confirmed before accepting an offer.
