Compare payment providers by the decision that actually matters: expected take-home revenue, tax workload, refund behavior, chargebacks, customer geography, and the operating work behind each checkout choice.
A SaaS checkout provider is not chosen only by headline percentage. A $9 monthly tool, a $99 annual plan, and a global B2B product can all produce different winners from the same provider list.
Before comparing Stripe, Paddle, Lemon Squeezy, or Polar, write down monthly revenue, order count, average order value, international card share, refund rate, and whether the team wants to own tax operations.
Stripe is usually modeled as direct payment processing. Paddle, Lemon Squeezy, and Polar are often considered merchant-of-record or MoR-like options because they can bundle more tax, checkout, and payment operations.
The cheapest processor on raw card fees may still be the wrong choice if the team is not ready to handle international tax registrations, invoices, dispute workflow, and buyer support.
| Provider path | Usually strongest when | Watch carefully |
|---|---|---|
| Stripe direct processing | You want control, already own tax workflow, and have enough order value to absorb fixed fees. | Tax tooling, international cards, disputes, filing, and support are separate decisions. |
| Paddle merchant of record | You want a bundled global SaaS checkout and prefer fewer tax operations inside the company. | The headline fee can look higher, so compare it against time and compliance cost. |
| Lemon Squeezy merchant of record | You want a lightweight MoR path for digital products or a smaller SaaS checkout. | Check feature coverage, payout timing, refunds, and whether your SaaS use case fits. |
| Polar | You want a modern developer-friendly checkout path and are comfortable checking current plan details. | Plan terms and fee assumptions should be verified before relying on a model. |
The common mistake is comparing one provider with a best-case assumption and another with a worst-case assumption. Keep revenue, order count, refund rate, and card mix identical while testing providers.
The calculator can show which option has the highest modeled net revenue. The final choice may still favor a provider with lower operational burden, better buyer experience, or better fit with accounting workflow.
Start with the same revenue, order count, and international share for every provider.
Open calculator scenarioIt depends on order size, international card mix, refunds, chargebacks, and tax workflow. Direct processors can be cheaper on raw card fees, while merchant-of-record providers can reduce operating work.
Use Stripe if you want more control and can own tax and operations. Consider a merchant of record if global tax, invoices, payment support, and compliance workload would slow the team down.
You can model the decision directionally, but final pricing should always be checked against each provider's official pricing page before choosing a checkout stack.
