Free SaaS Checkout Fee Diagnosis

Send your SaaS checkout assumptions first. The free screening checks whether Stripe, PayPal, Paddle, Lemon Squeezy, Polar, or a merchant-of-record setup is the right first path to investigate.

What you get

First, a quick screening of your monthly revenue, order count, international card share, refund assumptions, current provider, and whether a merchant-of-record setup is worth modeling before you wire checkout.

  • Whether the calculator result is already clear enough
  • Whether Stripe-style processing is probably enough
  • Whether Paddle, Lemon Squeezy, or Polar may justify higher fees
  • Which assumptions to verify with the self-serve decision kit

The diagnosis is free. The paid option is a separate self-serve digital kit with downloadable templates and checklists.

Pricing

The diagnosis is free. The paid option is the SaaS Checkout Fee Decision Kit, a self-serve digital download for running the decision process yourself.

Good fit

You are choosing a checkout stack before launch, switching away from Stripe, adding EU or global customers, or selling low-ticket SaaS where fixed fees matter.

Not a good fit

You need tax, legal, accounting, or financial advice. This is a practical checkout economics review, not a professional compliance opinion.

Example output

For a $9 monthly plan with 850 orders and 40% international cards, annual billing may matter more than switching providers. Stripe can look cheaper, but merchant-of-record tooling may be worth testing if tax and support work would slow the launch.

What makes a case worth reviewing

A decision worksheet is useful when the answer changes across scenarios: monthly versus annual billing, domestic versus global customers, direct processing versus merchant of record, or low refund rate versus realistic refund rate. If the winner never changes, the free diagnosis is usually enough. The kit helps document those assumptions before implementation.
