Stax

Public Pricing
Membership

Subscription-style (membership) pricing platform aimed at established, higher-volume businesses that want to reduce per-transaction margins.

Quick Answer

Stax is well suited to established businesses with steady, higher monthly processing volume that want to reduce per-transaction costs. Its membership pricing replaces the processor's percentage markup with a flat monthly fee plus interchange pass-through. Very low-volume businesses are unlikely to offset the monthly fee through per-transaction savings.

Frequently Asked Questions

How does Stax's membership pricing model work?

Stax charges a flat monthly membership fee in place of a traditional percentage-based processor markup. On top of the membership fee, merchants pay the actual interchange rates set by Visa and Mastercard plus a small per-transaction flat fee. At sufficient volume, eliminating the percentage markup results in a lower effective rate than flat-rate pricing. Verify current membership tiers and fee structure on Stax's pricing page.

What processing volume does Stax require?

Stax does not publicly state a hard minimum processing volume, but its membership model is financially advantageous primarily for businesses processing several thousand dollars or more per month. Very low-volume merchants may not generate enough savings to offset the monthly membership fee. Verify current plan minimums and whether your volume makes membership pricing beneficial.

What is the break-even volume for Stax versus flat-rate pricing?

The break-even point depends on your average transaction value, card mix, and the Stax plan you select. Businesses processing primarily credit cards with higher average transaction values tend to benefit more from membership pricing. Use a cost comparison calculator — or ask Stax's sales team — to model your specific volume and transaction mix before committing.

Does Stax support in-person and online payments?

Yes. Stax supports both in-person payments (with POS terminal options) and online payments (via payment gateway integrations). Its membership pricing applies across both channels. Verify current hardware options, gateway integrations, and any channel-specific fees directly with Stax.

Does Stax require a long-term contract?

Stax offers membership plans that may include multi-month or annual commitments. Contract terms vary by plan. Verify current contract lengths, cancellation policies, and any early termination fees directly with Stax before signing.
