Frequently Asked Questions

How much does Stripe cost per year?

Stripe charges 2.9% + $0.30 per online transaction. For a company processing $5M/year in payments, that is approximately $145,000–$175,000/year in processing fees. International cards, currency conversion, and Stripe Radar add additional fees.

When should I switch from Stripe to custom payment processing?

Switch when you process $2M+/year in payments. A custom payment integration with a direct processor costs $60,000 to build with $5,000/year maintenance. Direct processor rates (1.5–2.2%) save $35,000–$65,000/year at $5M revenue compared to Stripe 2.9%.

What are the risks of depending on Stripe?

Stripe can hold funds, freeze accounts, or increase rates with limited notice. Companies in perceived "high-risk" industries are especially vulnerable. A direct processor relationship gives you contractual rate guarantees and eliminates platform dependency risk.
