Stripe or Mollie? The choice comes down to three things
Both work fine. But subscriptions, marketplace payouts and whether your customers expect iDEAL make the difference. An honest comparison.
This question comes up in almost every project with money running through it. The answer is rarely a matter of principle. It comes down to what you sell, to whom, and how complicated your flow of money is.
1. Who are your customers?
If you sell to Dutch consumers, iDEAL is not a nice-to-have but the default. Mollie is built entirely around that: the payment page feels Dutch, the bank picker sits where people expect it. Stripe supports iDEAL too, but the flow is a shade less obvious to anyone who does not work with it daily.
Sell internationally or to businesses and it flips. Stripe covers more countries, more currencies and more local methods, and the invoicing around it is more mature.
2. One-off or recurring?
For one-off payments both do exactly what you want and the difference is negligible. The moment subscriptions enter the picture, Stripe gets more interesting. Trial periods, mid-term upgrades with pro-rata settlement, automatic retries on failed collections: it is all in there and you do not have to build it. With Mollie you end up writing part of that logic in your own application.
3. Does money go to third parties?
If you are building a marketplace or platform where you receive money and pass it on to connected parties, that is an entirely different problem. Both have an answer for it, and in both cases it is the part that eats the most build time. Count on identity checks for your sellers and on a payout rhythm you have to settle up front.
What goes wrong in practice
- Relying on the return to your site instead of on webhooks. A customer who closes the tab after paying has still paid.
- Storing amounts in euros instead of in cents as a whole number
- No idempotency on your webhook endpoint, so a duplicate notification creates a duplicate order
- Only thinking about refunds after the first customer asks for one
My rule of thumb
Dutch consumers, one-off payments, live quickly: Mollie. Subscriptions, international, or a more complex flow of money: Stripe. And in both cases: build the integration so you can get off it in two years, because you will not be the first to change your mind.
