Strong feature set, watch the fees

Stax handles our recurring billing reliably and the reporting is solid. Fees add up at our volume, so we negotiated custom pricing once we grew.

Pros

Recurring billing, reporting, uptime

Cons

Standard pricing is steep at scale

Use case: Subscription billing for a SaaS product

The API made this easy

Building split payments for our marketplace would have taken months elsewhere. With Stax the API and docs got us live in weeks. Webhooks are reliable.

Pros

Great API, split payments, webhooks

Cons

Some advanced features need a sales call

Use case: Split payments and payouts for a marketplace
