Mollie vs Square Pricing (2026)

Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.

How do they charge?

Different approach here. Mollie uses usage-based pricing, while Square goes with flat-rate. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Mollie: Mollie plays the no-friction, no-lock-in card against processors like Stripe and Adyen — same usage-based logic, but leaning hard on transparency (no hidden fees, no monthly minimums) to win over SMBs and mid-market merchants who hate surprise costs. It's not the cheapest per-transaction necessarily, but it's positioned as the fairest deal for anyone wary of long contracts. Square: Square sits in the middle-to-low end on sticker price, using the free tier as a wedge against Shopify POS and Clover, who rarely give away that much for nothing. The real competitive battle happens on processing rates, not the monthly fee, which is where Square tries to win small merchants who'd otherwise get nickel-and-dimed elsewhere.
