The Financial Reality of Payment Gateways vs. Merchant of Record (MoR)
On a $10 sale, Stripe's $0.30 fixed fee represents 3.0% of your total price alone! Combined with the 2.9% base fee and 1.5% international surcharge, your true effective rate on a $10 ticket exceeds 7.4%. For micro-pricing, flat-percentage platforms like Whop (flat 3%) or Polar can save hundreds of dollars a month.
While pure gateways like Stripe look 1%–2% cheaper on paper, you remain legally responsible for registering, collecting, and remitting sales taxes across the US (45 states), EU (27 countries), and UK. Using an MoR (Paddle, Lemon Squeezy, Dodo) offloads this compliance burden entirely.
