Pay by Bank vs Card Payments: Compare Costs and Fit
Understand customer-authorised bank payments, calculate realistic fee differences and check the effect on checkout, refunds and cash flow.
The short answer
Pay by Bank can offer a different cost structure from cards, but the useful saving depends on your quote, payment sizes and how many customers actually use it. Compare completed payments, platform charges and the customer journey. Fast payment confirmation does not necessarily mean an immediate payout into your business bank account.

What does Pay by Bank mean?
In a customer-authorised Pay by Bank checkout, the customer selects a bank and approves the payment through the bank’s app or web service. This differs from manually copying your account details into a bank transfer. It also differs from a Direct Debit mandate authorising future collections.
Stripe’s documentation describes this customer approval flow and lists its ordinary Pay by Bank method as single-use, with recurring functionality in private preview. Availability varies by product. Do not assume a one-off bank payment also sets up a subscription.
Check the journey from checkout to reconciliation
| Question | What to establish |
|---|---|
| Customer access | Which banks, accounts, currencies and payment amounts are supported? |
| Checkout completion | Can customers return successfully from their banking app to the order confirmation? |
| Payment status | Which provider status confirms payment, and what happens if approval is delayed? |
| Matching the sale | Does the payment carry the order or invoice reference your team needs? |
| Alternative methods | Can customers use another supported method when bank payment is unsuitable? |
A lower fee only helps on payments that complete. Record how many eligible customers choose the method and how many finish the checkout. Do not forecast that every card customer will move to bank payments just because the option is available.
Worked example: adoption changes the saving
Fictional offers. Assume £10,000 monthly sales in 200 equal £50 payments. Cards cost 1.5% plus 20p per payment. Bank payments cost 0.5% plus 10p, with an additional £20 monthly platform charge. No other fees are assumed.
| Scenario | Card fees | Bank fees and platform | Monthly total |
|---|---|---|---|
| All cards | £190 | £0 | £190 |
| All bank payments | £0 | £70 + £20 | £90 |
| Half cards, half bank payments | £95 | £35 + £20 | £150 |
The all-bank scenario saves £100 a month; the mixed scenario saves £40 a month. With £240 of additional setup cost, first-year savings would be £960 or £240 respectively, across twelve identical months.
In your own comparison, retain any card subscription or terminal cost that continues. Include actual minimums, caps, refund charges and VAT consistently where applicable. A fee cap is normally applied according to the quoted transaction rules, not assumed across the whole month.
Separate confirmation, payout and refunds
Stripe lists real-time payment functionality alongside standard payout timing for its Pay by Bank product. These are different stages. Ask when the provider confirms receipt, when your balance becomes available and when money reaches your bank. Compare that with your existing settlement arrangements.
Check how full and partial refunds work, what they cost and what happens to delayed or unsuccessful payments. Customer protections, dispute processes and provider liability can differ between payment methods. Do not describe a bank payment as fraud-proof or assume that the absence of a card chargeback process removes every possible claim or obligation.
Use a small, measured cost comparison
- Obtain a written tariff covering your business, payment sizes and required checkout tools.
- Start with your current card costs and the sales that could realistically move.
- Model several adoption levels, including a low-use scenario with the full platform fee.
- Record completion, refund handling and reconciliation effort during a practical trial.
- Review the actual cash and operational results before expanding the change.

Common questions
Is Pay by Bank the same as Direct Debit?
No. A one-off Pay by Bank checkout asks the customer to authorise that payment. Direct Debit uses a mandate for collections. Products can combine methods, so check exactly what the customer is agreeing to.
Will bank payments always cost less than cards?
No. The result depends on transaction sizes, payment counts, platform fees, the written tariff and how many customers use the method. Compare the total cost of the payment mix you expect to retain.
