Which payment gateway is cheapest for small businesses in Europe?

For low to moderate transaction volumes in Europe, Mollie and PayPlug often come out ahead because they charge no monthly fees on their starter plans. Stripe's 1.5% + €0.25 for European cards is competitive, but PayPlug starts at 1.2% + €0.25 on its premium plan, and Mollie charges as low as €0.25 flat on certain methods like iDEAL or Bancontact.

Can I use multiple payment gateways on the same e-commerce store?

Yes. Many platforms like PrestaShop and WooCommerce allow you to activate several payment modules simultaneously. This lets you offer customers more payment methods and gives you a fallback if one provider experiences downtime. An experienced agency like Lueur Externe can configure multi-gateway setups seamlessly.

How to Choose the Right Gateway

There is no one-size-fits-all answer. Consider these factors:

Your primary market: France-only? PayPlug shines. Multi-country? Mollie or Stripe.
Your technical resources: no developer on staff? PayPlug or Mollie are simpler. Custom stack? Stripe wins.
Transaction volume: at higher volumes, PayPlug’s Pro plan and Stripe’s volume discounts become significant.
Payment methods: if your customers use iDEAL, Klarna, or Bancontact, Mollie covers them out of the box.

At Lueur Externe, we’ve integrated all three gateways across dozens of PrestaShop and WordPress projects since 2003. Our team helps SMBs evaluate not just cost, but conversion impact — because a 0.5% improvement in checkout completion often outweighs a 0.3% difference in transaction fees.

Conclusion: Make Your Payment Stack a Growth Lever

Your payment gateway is more than plumbing — it directly affects revenue. Stripe delivers unmatched flexibility, PayPlug offers simplicity for the French market, and Mollie provides excellent pan-European coverage at transparent prices.
