Merchant Cash Advance Affordability & Underwriting: How Providers Assess Your Business

Quick answer: how does merchant cash advance underwriting work?

Merchant cash advance providers commonly assess the strength and consistency of a business's sales, its trading history and the quality of the revenue being generated before deciding whether to offer funding and how much may be available.

Depending on the provider, underwriting can consider information including:

• monthly card or online sales
• recent revenue trends
• consistency of trading
• time in business
• refunds
• chargebacks and disputes
• existing finance
• bank-account information
• payment-processing history
• sector or business activity
• the payment platforms used by the business.

There is no universal merchant cash advance underwriting formula. Providers have different minimum criteria, risk appetites, data sources and ways of assessing a business.

Meeting a provider's minimum criteria also does not guarantee approval or mean that the maximum available advance is necessarily affordable for the business.

Merchant Advice Service is an independent UK payments information, comparison and provider-matching service. We help businesses understand merchant finance alongside the payment-processing and settlement arrangements that can underpin it, and identify potentially relevant commercial partners where appropriate.

Merchant cash advance eligibility and affordability are not the same thing

This is one of the most important distinctions for a business considering an MCA.

Eligibility asks whether a provider is prepared to offer the finance.

Affordability asks whether the proposed collection structure works comfortably within the business's actual cash flow.

A business could meet a provider's eligibility criteria and receive an offer but still decide that:

• the percentage of sales being collected is too high
• the total cost is unattractive
• too little working cash would remain during busy months
• existing finance already places pressure on cash flow
• the payment-processing requirements are too restrictive
• another type of commercial finance would be more suitable.

The question should therefore not stop at:

“How much MCA can I get?”

Businesses should also ask:

“How much sales-linked finance can this business comfortably support?”

What information do MCA providers look at?

Individual underwriting models are proprietary and vary between providers.

However, current public information from merchant finance providers demonstrates several recurring areas of assessment.

How important is monthly card turnover?

For many merchant cash advance products, recent card or online sales can be a central part of underwriting.

This is because sales data can help the provider assess both:

• the amount of finance that might be offered
• the revenue available for percentage-of-sales collections.

However, there is no universal minimum turnover requirement.

Current providers demonstrate how different criteria can be.

365 Finance currently states that businesses applying for its Rev&U cash advance must have been trading for at least six months and take at least £10,000 per month in credit and debit card sales.

View 365 Finance's current eligibility information.

Stripe Capital's current UK documentation publishes different minimum criteria for its own platform-linked financing, alongside additional underwriting considerations.

The figures used by one provider should therefore not be treated as a market-wide MCA eligibility threshold.

Does higher turnover mean you will get a bigger MCA?

Not automatically.

Revenue is important, but the amount processed does not tell the whole story.

Consider two businesses each processing:

£100,000 per month.

Business A might have:

• consistent sales
• low refund levels
• few chargebacks
• several years of trading history
• a broad customer base.

Business B might have:

• rapidly declining sales
• large refunds
• frequent disputes
• significant existing finance
• highly concentrated customers.

The headline turnover is identical.

The underlying business and payment profiles are not.

This helps explain why MCA underwriting can look at the quality and pattern of revenue, not simply its size.

Why does sales consistency matter?

A consistent payment-processing history can provide the provider with more information about how the business normally trades.

For example, Stripe Capital currently identifies a steady processing record with limited periods of very low or zero processing volume as one factor that can improve the likelihood of eligibility for its UK financing.

View Stripe Capital's current UK underwriting information.

A business that usually processes £50,000 each month might therefore present a different profile from one whose recent sales were:

• £5,000
• £90,000
• £12,000
• £80,000.

That does not mean fluctuating businesses cannot obtain sales-based finance.

Seasonal businesses naturally have variable revenue.

The provider may instead need to understand why the sales pattern moves and whether that pattern is normal for the business.

Does sales growth affect MCA underwriting?

It can.

A provider assessing historic transaction information may consider whether revenue is:

• growing
• stable
• declining
• highly volatile.

Stripe currently says payment volume influences the size of a Capital offer and identifies positive growth trajectories as one characteristic that can support eligibility.

Shopify also says sales performance is a primary factor affecting Capital eligibility and offer size.

View Shopify Capital's current eligibility criteria.

Again, these are examples of individual underwriting models rather than universal MCA rules.

How much trading history do you need for an MCA?

There is no single minimum trading period across the whole market.

Current published requirements illustrate the variation.

For example:

• 365 Finance currently publishes a minimum six-month trading requirement for its Rev&U product
• Shopify Capital considers stores that have been operational for at least three months or made their first sale more than three months ago, subject to its other eligibility requirements
• Stripe Capital currently requires businesses to have processed payments through Stripe for at least three months as part of its UK minimum criteria.

Meeting a minimum trading period does not guarantee finance.

It simply means one basic criterion may have been met.

What does an MCA provider learn from your payment-processing statements?

Payment-processing information can reveal considerably more than headline turnover.

Depending on the statement and provider, it can help show:

• monthly processing volume
• number of transactions
• average transaction value
• sales fluctuations
• refund activity
• chargebacks
• processing currencies
• Merchant IDs
• payment channels
• settlement deductions.

This is why transaction data can be particularly useful in sales-based underwriting.

If you are unsure how to interpret your processing information, read our guide to understanding merchant-processing statements.

Can MCA underwriting use Open Banking?

Yes, some providers use Open Banking or business-bank data as part of their assessment.

This can provide a more current picture of money entering and leaving the business.

YouLend currently states that it uses Open Banking to access payment data and generate tailored funding offers.

Its technical onboarding documentation also allows bank statements, sales data and business information to be provided as part of an application before automated decisioning takes place.

View YouLend's current onboarding documentation.

365 Finance has also explained publicly that it uses Open Banking to gain visibility of business outgoings and current cash-flow performance when assessing affordability.

View 365 Finance's explanation of Open Banking and affordability.

Why are bank statements relevant if an MCA is based on card sales?

Card revenue shows only one side of the business.

A provider may also need to understand what happens to the money after settlement.

For example, a business could process £80,000 per month but also have substantial:

• supplier payments
• payroll
• rent
• tax liabilities
• existing loan repayments
• other finance deductions.

Banking information can therefore provide useful additional context about cash flow and existing commitments.

The British Business Bank also identifies cash flow as a key indicator lenders and investors can consider when assessing business finance.

British Business Bank: Getting Your Business Ready for Finance.

Do refunds affect MCA underwriting?

They can.

Gross sales and retained sales are not always the same thing.

Imagine two ecommerce businesses both processing:

£100,000 per month.

One refunds £3,000.

The other refunds £25,000.

The reported processing volume is the same, but the underlying revenue profile is very different.

Shopify currently lists the frequency of returns among the factors affecting Capital eligibility.

Other finance providers can use different underwriting models.

Businesses with naturally high return levels should be ready to explain how refunds operate within their sector and cash-flow model.

Do chargebacks affect MCA approval?

They can be relevant to underwriting.

Chargebacks may indicate:

• customer disputes
• fulfilment problems
• fraud exposure
• future payment liabilities
• potential pressure on settlement.

Stripe currently identifies a low unresolved dispute rate as one factor associated with Capital eligibility.

Shopify also lists chargebacks and disputes among the factors it uses in determining Capital eligibility.

No single chargeback percentage should be presented as a universal MCA approval or rejection threshold.

Criteria vary between providers and business sectors.

Does a rolling reserve affect MCA affordability?

It can have a significant effect on the amount of usable cash remaining after sales.

A rolling reserve and an MCA collection are separate arrangements.

But a merchant could potentially experience both at the same time.

For example, processed revenue could be affected by:

• normal card-processing fees
• a rolling reserve
• refunds
• chargebacks
• an MCA sales-based collection.

The MCA provider may decide that the business is eligible for finance.

That does not automatically mean the combined effect of those deductions is comfortable for the merchant.

Merchant Advice Service view: eligibility is not affordability

Merchant Advice Service believes businesses should distinguish between the amount a provider is willing to offer and the amount the business can comfortably support.

This is especially important with sales-linked finance.

A provider may assess historical revenue and produce an offer based on its underwriting model.

The merchant should then carry out a second assessment of its own:

What happens to our usable cash after the MCA collection?

MAS recommends considering the full payment and cash-flow chain:

sales → processing fees → refunds → chargebacks → reserves → existing finance → MCA collection → usable business cash.

For some businesses, the proposed advance and collection percentage may fit comfortably.

For others, taking the maximum amount offered could leave too little cash available for normal business operations.

How can you test MCA affordability?

A useful starting point is to model the proposed collection against different levels of sales.

Consider a business with:

• average monthly eligible sales: £50,000
• MCA collection percentage: 15%.

At average sales, the estimated monthly collection would be:

£50,000 × 15% = £7,500.

But the business should not model only its average month.

Stress-test a weak, normal and strong month

These are simplified mathematical illustrations.

The final column is not the business's profit or usable bank balance because it does not yet account for:

• payment-processing fees
• cost of goods
• payroll
• VAT and tax
• rent
• refunds
• reserves
• existing finance
• other operating costs.

This is why affordability cannot be determined from turnover alone.

High turnover does not automatically mean strong affordability

A business processing £200,000 per month may appear substantially stronger than one processing £50,000.

But turnover is not profit and it is not necessarily free cash flow.

The higher-turnover business might operate on very narrow margins or need significant cash for:

• inventory
• fulfilment
• wages
• marketing
• tax
• customer refunds.

A percentage-of-sales deduction should therefore be assessed against the economics of the business, not turnover in isolation.

Does seasonality affect MCA underwriting?

Yes, it can be relevant.

A seasonal sales pattern is not automatically a negative signal.

Hospitality businesses, retailers, tourism businesses and ecommerce merchants can all experience predictable peaks and troughs.

The important distinction is between:

normal seasonality

and:

unexpected deterioration in trading.

If the provider is looking at only a short period of payment data, businesses may find it useful to ensure the normal seasonal nature of their trading is understood.

From the merchant's perspective, seasonality also matters because percentage-of-sales collections can become substantially larger during peak months.

Can a seasonal business afford an MCA?

Potentially, but businesses should model both ends of the cycle.

A sales-linked collection can reduce automatically during quieter months if the agreement genuinely applies a fixed percentage to eligible revenue.

However, during peak season the deduction also increases.

If the business depends on its peak cash flow to:

• buy next season's stock
• pay annual liabilities
• build reserves
• fund expansion

the larger peak-period MCA collection needs to be included in the forecast.

Does your business sector affect MCA approval?

It can.

Finance providers do not all have identical sector appetites.

A business may satisfy turnover and trading-history requirements but still fall outside the particular provider's criteria.

YouLend's current prequalification documentation, for example, explicitly notes that there are industries it cannot fund and provides its partners with disallowed SIC-code information.

View YouLend's current prequalification documentation.

This is another reason businesses should avoid treating an MCA rejection as evidence that every provider will reach the same decision.

It may sometimes be a question of provider fit rather than the availability of merchant finance across the entire market.

Does your payment processor affect MCA underwriting?

It can, particularly where the finance is linked directly to card or online-payment revenue.

The provider may need to establish:

• which processor handles the sales
• which Merchant IDs are involved
• how much revenue passes through each payment channel
• where settlement is paid
• whether its collection method is compatible with the existing setup.

Some embedded finance products already have access to payment information because the funding is offered directly through the processor or ecommerce platform.

For independent MCA arrangements, the provider may require payment or banking information separately.

Read our Merchant Cash Advance and Your Payment Processor: Do You Need to Switch?.

What if you have more than one Merchant ID?

Multiple Merchant IDs can make the revenue picture more complicated.

A business might process:

• £40,000 through one in-store MID
• £30,000 through an ecommerce MID
• £20,000 through another acquirer.

Total card turnover is:

£90,000.

But the finance provider may not necessarily use all £90,000 in exactly the same way.

Ask:

• Which MIDs are included in the assessment?
• Which are included in ongoing collections?
• Can multiple processors be combined?
• What happens if a new MID is opened?
• What happens if processing is moved elsewhere?

Read our guide to multiple merchant accounts and Merchant IDs.

How does ecommerce MCA underwriting differ?

Ecommerce platforms can provide particularly detailed information about the health of an online business.

Shopify's current Capital eligibility criteria illustrate this.

Its published factors include:

• sales volume
• frequency of sales days
• number of orders
• successfully shipped orders
• customer engagement
• platform history
• returns
• chargebacks and disputes
• reserves
• payment-provider and payout arrangements.

This shows why ecommerce underwriting can potentially extend well beyond a simple monthly turnover number.

Read our full Merchant Cash Advance for Ecommerce Businesses guide.

Is a pre-qualified MCA offer guaranteed?

No.

A pre-qualified or automatically generated offer should not automatically be interpreted as final approval.

Shopify, for example, says receiving a Capital offer does not guarantee funding and that applications are subsequently reviewed. It can revise a pre-qualified amount downwards following review.

Stripe similarly states that its UK financing requests remain subject to final review before approval.

YouLend's technical documentation also distinguishes prequalification from the subsequent application, automated underwriting and decision process.

The terms:

• eligible
• pre-qualified
• indicative offer
• approved
• funded

should therefore not be treated as interchangeable.

Why might an MCA offer be lower than expected?

A provider does not necessarily disclose every component of its underwriting model.

However, factors that can potentially affect the outcome include:

• lower recent sales
• declining revenue
• short trading history
• volatile transaction patterns
• refund activity
• chargebacks or disputes
• existing financial commitments
• sector restrictions
• insufficient eligible revenue
• incomplete business or verification information.

The provider's own exposure limits and commercial appetite can also affect what it is prepared to offer.

Does an MCA provider check your credit?

It depends on the provider, product and agreement.

Merchant cash advance underwriting can place substantial weight on current business and sales performance, but that does not mean credit information is never relevant.

Stripe Capital's current UK criteria, for example, require the individual applying for and guaranteeing an offer to have a UK address to support a credit check.

Stripe Capital: UK Eligibility.

Businesses should therefore be cautious of broad claims that merchant cash advances involve “no credit checks” or that credit history can never affect an application.

Do you need perfect credit for an MCA?

No universal credit-score requirement applies across the entire MCA market.

Different providers use different underwriting models and data.

Sales-based finance may place more emphasis on the current trading performance of the business than some conventional lending models.

However, that does not mean every business with strong card sales will qualify, or that credit and existing financial obligations are irrelevant.

For businesses seeking help, the more useful approach is to identify providers whose actual criteria fit the business rather than searching for a supposed universal “minimum MCA credit score”.

How does existing finance affect MCA affordability?

This is particularly important.

A business could already be paying:

• a business loan
• asset finance
• invoice-finance charges
• another revenue-based facility
• credit-card balances
• an existing MCA.

Those commitments already reduce available cash.

A new MCA collection would sit alongside them.

This means the merchant's true question should be:

“How much cash remains after all existing and proposed finance commitments?”

Existing finance should be disclosed accurately when requested during an application.

Can you have two merchant cash advances at the same time?

Potentially, depending on the agreements and providers involved, but businesses should be particularly cautious about the cumulative cash-flow effect.

For example, if one facility collects:

10% of eligible sales

and another arrangement creates a further sales-linked deduction, the business could lose a significant proportion of each day's revenue before normal operating costs are paid.

Existing contracts may also contain restrictions or obligations that affect additional finance.

Do not take a second advance without understanding how it interacts with the first.

What documents might you need for an MCA application?

Requirements vary between providers and some embedded finance applications use data already held by a payment or ecommerce platform.

Depending on the provider and application, businesses may be asked for information such as:

• business and company details
• director or beneficial-owner information
• identity verification
• bank statements
• payment-processing statements
• sales data
• details of existing finance
• business accounts or other financial information
• information about the purpose of the funding.

YouLend's current onboarding documentation, for example, describes applications being enriched with bank statements, directors and sales data before being submitted for automated decisioning.

How can you prepare for MCA underwriting?

Businesses can make the assessment easier by preparing accurate information before applying.

1. Know your average monthly card and online sales.
2. Understand whether sales are rising, stable or falling.
3. Have recent payment-processing information available.
4. Know your refund and chargeback position.
5. List existing business finance accurately.
6. Understand your Merchant IDs and processors.
7. Be ready to explain genuine seasonality.
8. Know what the funding will be used for.
9. Calculate how much of your sales you can comfortably give up.

The aim should not be to make the business look artificially stronger.

It should be to provide an accurate picture so the provider and merchant can assess the finance properly.

Should you apply for the maximum MCA available?

Not automatically.

The largest amount a provider is prepared to offer may be more than the business actually needs.

A larger advance can potentially mean:

• a larger total collection
• a different collection percentage
• a greater proportion of future cash flow being committed
• more finance cost than necessary.

Start with:

“How much does the business actually need?”

Then compare that with:

“How much can the business comfortably support?”

Only after that should the maximum available amount become relevant.

How much MCA can your business comfortably afford?

There is no universal affordability percentage.

The same 10% or 15% deduction can have very different consequences for different businesses.

A high-margin digital business may be able to absorb a sales deduction differently from a low-margin retailer that must continually replace inventory.

Affordability should consider:

• gross margin
• cost of stock
• staff costs
• tax
• rent
• existing finance
• refunds
• reserves
• other payment deductions
• the cash buffer the business needs to operate.

For a full explanation of the numbers, read our Merchant Cash Advance Costs, Factor Rates and Repayments guide.

What if an MCA is available but not affordable?

The answer does not have to be another MCA.

This is where broader commercial-finance comparison can become useful.

Depending on what the money is required for, alternatives could potentially include:

• a business loan
• asset finance
• invoice finance
• a revolving credit facility
• another revenue-based finance structure
• other specialist commercial finance.

A business seeking £50,000 for new machinery, for example, should not automatically assume that an MCA is the only way to fund it.

Read our guide to using a merchant cash advance broker or going direct.

Underwriting criteria can change

MCA underwriting is not static.

A business that does not receive an offer today may have a different profile later if:

• sales increase
• its trading history becomes longer
• transaction consistency improves
• existing finance reduces
• chargeback or refund patterns change
• a different provider's appetite fits the business better.

Likewise, a previously available offer does not necessarily remain available indefinitely.

Shopify states that Capital eligibility and offer sizes are continually evaluated and can change.

Stripe also evaluates its UK businesses regularly for Capital eligibility.

An indicative offer should therefore be treated as current information rather than a permanent funding entitlement.

Does FCA affordability regulation apply to every MCA?

No. The regulatory position depends on the legal structure of the finance, the borrower and the agreement.

The FCA's consumer-credit creditworthiness and affordability rules apply where an agreement falls within the relevant regulated-credit regime.

They should not be presented as though every commercial MCA issued to every UK business automatically sits within that regime.

Where regulated credit does apply, the FCA's rules require relevant firms to consider both credit risk and affordability risk as part of a reasonable creditworthiness assessment.

FCA Handbook: Creditworthiness Assessment.

Businesses should therefore avoid blanket statements that all MCA underwriting is either “FCA regulated” or “unregulated”.

The specific product and legal entity need to be considered.

Merchant Advice Service's MCA underwriting checklist

Before applying, Merchant Advice Service recommends understanding these nine areas:

1. Revenue: How much eligible revenue does the business generate?
2. Consistency: Is that revenue stable, seasonal or volatile?
3. Trend: Are sales growing, stable or declining?
4. Trading history: How much evidence of normal trading exists?
5. Payment quality: What do refunds, disputes and chargebacks look like?
6. Existing finance: What cash-flow commitments already exist?
7. Payment setup: Which processors, MIDs and sales channels are involved?
8. Affordability: What cash remains after the proposed deduction?
9. Provider fit: Does the business actually fit the criteria and appetite of the provider being approached?

The final point matters.

A business should not have to fit every MCA provider.

It needs to identify a provider or alternative finance structure that is relevant to its actual circumstances.

How Merchant Advice Service helps with MCA provider matching

Merchant Advice Service looks at more than whether a business appears technically eligible for merchant cash advance.

We help businesses understand areas including:

• sales profile
• merchant cash advance structure
• factor rates and total cost
• sales-based deductions
• payment processors
• Merchant IDs
• settlement arrangements
• rolling reserves
• ecommerce and multi-channel sales
• provider requirements
• alternative commercial finance options where relevant.

Our role is to help businesses better understand the requirement and identify potentially relevant commercial partners from the options available to us where appropriate.

MAS does not make the final underwriting decision and does not guarantee approval.

We also believe that being offered funding and deciding that funding is right for the business are two separate decisions.

That is why our approach considers both:

provider eligibility

and:

the commercial impact on the merchant.

You can view merchant cash advance options through the Merchant Advice Service Payments Directory®.
