The short version

  • Each has a real cost: FastSpring pricing is not published and requires contacting sales for a quote, making cost comparison difficult upfront.; Mollie non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • They diverge on capability: FastSpring covers Global online payments, Mollie covers Local payment methods.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FastSpring

  • Pricing is not published and requires contacting sales for a quote, making cost comparison difficult upfront.
  • As a merchant-of-record, FastSpring takes on more control of the checkout and payment relationship than a pure payment gateway like Stripe.
  • Revenue share pricing can become more expensive than flat per-transaction gateway fees at very high volumes.
  • Primarily targeted at software/digital goods sellers, so it is less suited to physical product e-commerce.

Mollie

  • Non-European cards cost 3.25% plus 20p against 1.20% plus 20p for UK domestic consumer cards, so a merchant with significant traffic from the US or Asia pays close to triple the domestic rate on that revenue.
  • Coverage is built around European methods, so if you expand into Latin America or Southeast Asia you will need a second processor and a second reconciliation process rather than extending Mollie.
  • The in-person Pro plan requires a one-year contract and charges 20 pounds a month per additional terminal, so a shop with four tills pays 80 pounds a month in terminal fees before any transaction cost.
  • Mollie offers no interchange-plus option publicly, so large merchants cannot see or benefit from falling interchange the way they could on a cost-plus contract with an acquirer.
  • The developer tooling and reporting are lighter than the largest processors, so finance teams that want detailed fee breakdowns or granular reconciliation exports often end up building that layer themselves.

Answered from the vendors’ own pages

FastSpring: What does FastSpring cost?

FastSpring uses flat-rate, all-in-one pricing based on transaction volume, with fees withheld from payouts. There is no minimum volume or subscription fee, and pricing is typically quoted based on expected sales volume after contacting their sales team.

Source
Mollie: Does Mollie charge a monthly fee?

Not on the online payments plan. You pay only per successful transaction. In-person Pro is 20 pounds a month.

FastSpring: Is there a free plan?

FastSpring does not offer a free plan; instead pricing is transaction-based with no upfront subscription cost, and merchants only pay a commission on completed sales.

Source
Mollie: Is iDEAL really a flat fee?

Yes, 30p per transaction regardless of the amount, which is why it is cheaper than cards on high-value baskets.

FastSpring: What does FastSpring integrate with or include compared to a payment gateway like Stripe?

FastSpring bundles international payments, subscription management, tax compliance, fraud prevention, reporting, and B2B invoicing into one price, whereas gateways like Stripe charge separately for many of these features.

Source
Mollie: Can I use Mollie outside Europe?

You can accept non-European cards but at 3.25% plus 20p, and merchant accounts are aimed at European businesses. It is not a global processor.

Mollie: Does Mollie do interchange plus?

Not publicly. The published rates are blended, so falling interchange does not flow through to you automatically.
