If you've ever looked at your Stripe dashboard and done the math on 2.9% + $0.30 per transaction, you've probably wondered: is there a cheaper way?
Open banking (account-to-account payments) has been quietly eating into card-based payment volume in Europe — and the pricing model is structurally different in ways that matter a lot depending on your ticket size.
Here's what most SaaS founders miss.
The fundamental difference: % vs flat fee
Stripe charges a percentage of transaction value (2.9% + $0.30 in the US, 1.4%–2.9% + €0.25 in Europe depending on card type).
Open banking providers like TrueLayer and GoCardless charge a flat fee per transaction — typically £0.10–£0.50, sometimes with a small capped %.
This one structural difference changes everything at scale.
Where the break-even flips
Ticket size Stripe (EU, 1.4%) GoCardless TrueLayer Winner
£10 £0.39 £0.20–0.50 £0.20–0.50 ~Even
£50 £0.95 £0.20–0.50 £0.20–0.50 Open banking
£200 £3.05 £0.20–0.50 £0.20–0.50 Open banking
£500 £7.25 £0.20–0.50 £0.20–0.50 Open banking
£2,000 £28.25 £0.20–0.50 £0.20–0.50 Open banking
At £50+ ticket sizes, the savings compound fast. At £500, you're saving £6.75–7.00 per transaction. At £2,000 per transaction, the difference is ~£28 vs ~£0.50.
What open banking doesn't solve (yet)
Settlement speed is a hidden pricing lever. Instant settlement costs more than next-day on most open banking rails. GoCardless's Instant Bank Pay charges a premium vs standard. If you can tolerate T+1, you pay less. If you need funds same-day, factor that in.
Refunds and VRPs (Variable Recurring Payments) aren't always bundled. Traditional card payments have a standardised chargeback/refund flow. Open banking refunds require the provider to initiate a new payment back to the customer — this isn't always seamless, and VRP (the open banking equivalent of recurring billing) is still rolling out across UK banks.
No chargebacks — a double-edged sword. Cards have buyer protections that your customers expect. Open banking has no chargeback mechanism, which reduces your fraud exposure but may affect conversion if customers are used to card safety nets.
Geographic coverage limits you. TrueLayer and GoCardless are strong in the UK + parts of EU. For US or global SaaS, Stripe still wins by default. Plaid is strong on data/AIS in the US but lighter on payment initiation.
The hidden cost of Stripe you're probably ignoring
Stripe Tax: $0.50 per transaction if you enable it for VAT/sales tax compliance.
If you're selling to EU customers and using Stripe (not a Merchant of Record like Paddle), you're either paying Stripe Tax or handling VAT yourself. Open banking doesn't solve this either — it's purely a payment rail, not a MoR.

When to use what
Stick with Stripe if:
Global customer base (US, APAC)
Low ticket sizes (< £30)
Need card-on-file / subscriptions via card
Customers expect card safety nets
Switch to (or add) open banking if:
UK/EU focused
Ticket sizes consistently £50+
B2B payments where flat fee wins
Want to eliminate chargeback risk
Hybrid approach: Many UK SaaS companies now offer both — card for international and small tickets, open banking for high-value UK transactions.

If you process £100K/month at an average ticket of £500 (200 transactions):
Stripe (EU): 200 × £7.25 = £1,450/month
GoCardless: 200 × £0.40 = £80/month
Savings: £1,370/month → £16,440/year
