Key comparison

Total repayable + repayment mechanics

How a merchant cash advance works

  1. Step 1

    The provider advances funds

    The business receives an agreed amount upfront.

  2. Step 2

    Sales continue

    Eligible card, platform or other agreed sales are processed.

  3. Step 3

    Repayments are collected

    An agreed portion of eligible sales may be deducted toward repayment.

  4. Step 4

    Repayment continues

    Collections continue according to the agreement until the required amount has been repaid.

A merchant cash advance is not the same as a conventional term loan

Repayment is often linked to sales rather than a fixed monthly instalment, and cost may be expressed as a fixed fee, factor-style amount or another provider-specific structure.

Understanding costs and repayments

A fixed fee does not mean low cost. Compare the full obligation and how collections affect cash flow.

  • advance amount
  • total amount repayable
  • cost / fee structure
  • sales deduction percentage
  • sales eligibility
  • expected repayment period
  • early repayment treatment
  • minimum repayment rules where applicable
  • payment platform requirements

Advance amount

The amount provided to the business upfront.

Total repayable

The total amount the agreement requires to be repaid.

Sales deduction

The share of eligible sales used toward repayment.

Effective repayment period

The time repayment takes can vary with sales depending on the agreement.

Illustrative merchant cash advance example

Illustrative example only — not a current provider offer

Advance
£20,000
Total repayable
£24,000
Total finance cost
£4,000
Sales deduction
10%

If eligible monthly sales were £30,000, then a 10% sales deduction would be £3,000 toward the outstanding repayment.

Actual provider structures vary. Some products use different fee models, repayment percentages, sales definitions and minimum-payment rules.

Merchant cash advance vs other business finance

Provider structures vary. Compare total cost, repayment mechanics and eligibility for your scenario.

When a merchant cash advance may be worth exploring

  • the business receives regular eligible card / platform sales
  • working-capital needs are short term
  • the business values repayments that move with sales
  • traditional fixed-repayment borrowing is less suitable
  • the business understands the full repayment obligation

Compare alternatives carefully if:

  • margins are tight
  • deductions could materially reduce operating cash flow
  • conventional borrowing is available at materially lower total cost
  • revenue is volatile enough that repayment duration is uncertain
  • long-term funding is required rather than short-term working capital
  • the payment-platform dependency is restrictive

Risks and considerations

Total cost

The cost can be higher than some conventional forms of borrowing.

Cash-flow pressure

Sales deductions reduce cash received by the business while repayment continues.

Repayment uncertainty

Where repayment is sales-linked, the time taken to repay can vary.

Platform dependency

Some products are only available to businesses using a particular payment provider.

Personal guarantee

Some providers may require one depending on the product and circumstances.

Security / eligibility

Requirements vary and should be checked against the actual agreement.

What happens if sales fall?

Where repayment is genuinely linked to sales, the amount collected may reduce when eligible sales fall. However, the underlying repayment obligation does not necessarily disappear, and some agreements may contain minimum-payment or other conditions.

Before comparing merchant cash advances

  • How much will the business receive?
  • What is the total amount repayable?
  • How is the cost expressed?
  • What percentage of sales will be deducted?
  • Which sales count toward repayment?
  • Are there minimum sales requirements?
  • Is there a minimum repayment?
  • What happens if sales fall?
  • What happens if sales stop?
  • Can the advance be repaid early?
  • Does early repayment reduce the cost?
  • Is a personal guarantee required?
  • Is security required?
  • Is a specific payment platform required?
  • How does the total cost compare with a business loan or overdraft?
