A useful comparison starts with your actual SumUp offer and a written alternative offer for the same business need. It does not start with a generic ranking of providers. The advance amount, total collection, payment rules and effect on your existing payment-processing setup can matter more than the headline fee.
For a SumUp merchant, staying within an existing payment relationship may be convenient. An alternative could offer a different amount or structure, but may also introduce new costs, restrictions or operational work. Neither route is automatically better.
This guide provides a like-for-like method for comparing merchant cash advances in the UK. All calculations are illustrative, and provider references describe published information rather than a quotation or recommendation.
Establish the terms of the offer you actually have
SumUp's UK product page describes a fixed fee, sales deductions, an agreed repayment period and a minimum monthly payment. Its eligibility guidance states that meeting eligibility criteria does not guarantee an offer. Use your own offer and agreement for the actual figures and obligations.
Before comparing another provider, record the net cash available, total collection amount, collection percentage, qualifying-sales definition, minimum payments and final deadline. If the other quotation does not disclose the same information, the comparison is incomplete.

Do not treat a larger advertised maximum as a better offer. An amount you cannot access, do not need or cannot repay should not improve a provider's position in your decision.
A comparison table that exposes the important differences
Complete this table with actual written terms. Where a fact is unknown, record it as unknown rather than assuming both providers operate the same way.
| Comparison point | Question to answer for each offer |
|---|---|
| Net proceeds | What will reach the bank after deductions or settlements? |
| Total financing cost | What must be paid beyond the usable proceeds? |
| Collection base | Which transactions count, and how are refunds or adjustments treated? |
| Collection percentage | What share of those transactions is allocated to the advance? |
| Minimums and deadlines | What is due if proportional deductions are insufficient? |
| Processor compatibility | Can the business retain its existing payment setup? |
| Processing costs | Are new transaction, terminal, account or service charges involved? |
| Security and guarantees | Which assets or personal obligations support the agreement? |
| Early settlement | What amount clears the facility on a specified date? |
| Business changes | What restrictions affect closure, sale, account changes or additional borrowing? |
A provider's willingness to explain these points is useful, but clear explanations do not replace the written terms. Keep the documents you relied on and resolve inconsistencies before acceptance.

Example: the lower funding fee is not always the lower combined cost
Consider a fictional business seeking £10,000 of usable funding. Two hypothetical offers are available:
| Item | Offer A | Offer B |
|---|---|---|
| Net cash received | £10,000 | £10,000 |
| Financing charge | £1,400 | £1,000 |
| Total financing collection | £11,400 | £11,000 |
| Extra processing cost relative to the existing arrangement | £0 | 0.4 percentage points |
| Expected qualifying processing volume during the comparison period | £150,000 | £150,000 |
The additional processing cost under Offer B is £150,000 × 0.004 = £600. Its combined incremental cost is therefore £1,600, compared with £1,400 for Offer A, assuming every other relevant cost is equal.
This does not establish that SumUp or any particular alternative has those terms. It shows why you should count costs arising from a required processor change rather than comparing the funding fee in isolation.
The comparison period also matters. If the new processing price continues after the advance is cleared, calculate its longer-term effect. Conversely, if the new arrangement genuinely reduces processing costs, include that benefit using realistic sales volumes and the full fee schedule.
Example: a smaller collection percentage can take longer
Suppose two other fictional offers each provide £10,000 and require £11,500 in total. Offer C collects 10% of qualifying sales; Offer D collects 15%.
At £20,000 of qualifying monthly sales, the simple proportional collections are £2,000 and £3,000. The higher percentage removes £1,000 more from that month's available cash. Both still have the same assumed fixed financing charge, before considering minimums, deadlines or other conditions.
A lower deduction may leave more money available for wages and stock now, but it can keep the obligation outstanding longer. A higher deduction may finish sooner but create pressure during months when taxes or supplier bills fall due.
Do not rank these offers on percentage alone. Compare weekly closing cash and the lowest projected bank balance, including contractual minimums. Our guide to UK MCA cash-flow forecasting provides a framework for this assessment.
Compare how the provider defines sales
Two offers can quote the same percentage but apply it to different bases. Ask whether the calculation uses gross or net sales, how refunds are handled, and whether it includes channels beyond the card terminal you are considering.
For example, 12% of £25,000 is £3,000, while 12% of £20,000 is £2,400. That £600 difference cannot be understood from the percentage alone.
Avoid relying on an informal statement that collections “follow turnover”. Identify the defined revenue base and how it will be measured. If a business operates online, in person and through several processors, make sure the forecast matches the contract rather than one convenient dashboard total.
Platform-linked alternatives are not interchangeable
Some alternatives require an existing relationship with another payment platform. That can restrict whether they are realistic options for your business.
PayPal's UK Working Capital page describes sales-based collections and a fixed fee, with eligibility tied to the applicant's PayPal activity. Shopify's UK Capital guidance describes its own receivables-purchase structure and collection arrangements. Those are separate products with separate agreements, not generic offers available merely because a business uses SumUp.
A provider comparison should therefore separate options you can actually obtain from products that would require building a new trading history or changing the business's payment operations. Do not make a forecast depend on an unapproved future offer.
Check processor changes before signing a new agreement
If an alternative requires switching providers, map the operational steps as well as the price. Consider terminal setup, staff training, online checkout integration, reporting, settlement timing and existing service commitments.
If your current advance is outstanding, obtain written confirmation of how a switch would affect its collection mechanism and obligations. Do not assume that the new provider will automatically arrange a settlement or that a move cancels the existing debt or receivables obligation.

Use a downside scenario, not just your normal sales month
An offer can appear affordable when sales are strong. Test a lower-sales period with the same rent, core payroll and tax commitments. Also test a month with higher refunds or a delayed supplier delivery.
The objective is to identify a shortfall before signing. Record how much cash would be needed to meet any minimum payment if automatic collections fall below it. Include the source of that cash; a forecast is not solved by inserting an unexplained owner contribution.
If neither offer leaves adequate room for normal operations, taking the lower-cost one does not necessarily make the borrowing suitable. Consider a smaller funding request, staged purchasing, negotiated supplier terms or postponing a nonessential project.
Questions to send both providers
Ask each provider for a written response to these questions:
- What exact sum will the business receive, and what deductions occur first?
- What is the total required collection, including all charges?
- Which sales are included in the collection calculation?
- What minimum payments and deadlines apply?
- Can we keep our existing processor and bank account?
- What security, guarantees or other restrictions are required?
- What would a settlement cost after three months?
- What happens if sales fall materially or the business temporarily stops trading?
Use consistent scenarios. Asking one provider for a three-month settlement illustration and another for total contractual cost does not produce a like-for-like comparison.
Frequently asked questions
Is SumUp Cash Advance always cheaper than an independent MCA?
No reliable answer can be given without the two actual offers. Compare net proceeds, full costs, payment timing and terms. A generic comparison cannot determine your personalised pricing.
Should I choose the highest available advance?
Base the request on the business purpose and repayment capacity. More funding can create more cost and larger collections without producing a proportional benefit.
Can I apply elsewhere if SumUp has not offered funding?
You can investigate alternatives, but their criteria and payment compatibility may differ. An absence of an offer from one provider is not evidence that another will approve you.
Does a lower fixed fee automatically mean better value?
No. Include all required costs and compare timing. Also consider whether the agreement is compatible with the business's operations and whether its obligations are acceptable.
Make the decision from written terms and cash flow
Bring both offers into one forecast and identify the lowest cash balance under each. Combine that with total cost and the operational consequences of any processor change. The most useful decision is the one supported by complete figures and a credible repayment source.
