Stax card processing fees: what a shop actually pays
This provider publishes prices, but not ones a total can be built from. Either the rate is quoted as a starting figure, or it is interchange plus a markup, where the largest part of the cost is set by the card networks and is not published anywhere on the page.
Everything below is what the provider does state publicly, with the parts it does not state marked as such.
What does the provider publish?
Stax publishes the plans below on its own pricing page; the last column quotes the conditions in the provider's words.

|---|---|---|---|---|---|---|
| Subscription, up to $150k a year | $99.00 | $125 once | interchange + 0.00% + $0.08 | 0.00% | — | Interchange is set by the card networks and is not published by the provider, so the total cannot be computed. $99/month with 0% markup on direct-cost interchange; $0.08 card present, $0.15 keyed.

What is fixed and what moves with sales?
Stax publishes both the percentage and the per-transaction fee. On Subscription, up to $150k a year the fixed part is $99.00 a month before a single card is tapped, which is 1.98% of card sales at $5,000 a month and 0.20% at $50,000. checked 2026-08-25
A percentage on its own says nothing about what a small shop pays. The monthly fee, the terminal and the per-transaction fee are fixed amounts, so they land hardest on the shops with the least card volume — which is the opposite of how the headline rate reads.
Who owns it?
Who owns this company is not stated on its own site, and we could not confirm it from a primary source. We have left it blank rather than repeat what other sites say.
Where this leaves you
- You cannot budget from this page. Ask for the rate in writing, for debit and credit separately, plus the monthly fee, the terminal cost, the minimum monthly charge and the length of the contract, before anyone books a call.
- Ask what the rate is on business and foreign cards. It is the most common reason a statement comes back higher than the quote.
- Providers that do publish a rate are listed in the full list.
Who this page is not for
This is not a review. We have not used Stax, we hold no opinion on its hardware or its support, and nothing here is a recommendation. It answers one question: what the published price turns into as a share of card sales.
