Overview

Stax is an all-in-one payment processing platform that operates on a subscription-based model. Instead of charging a percentage markup on each transaction, businesses pay a monthly membership fee and get direct access to the wholesale interchange rates from card networks. The platform also includes a suite of business tools for invoicing, recurring payments, and data analytics.

✨ Key Features

  • Subscription-based pricing (0% markup)
  • Direct access to interchange rates
  • Payment processing for all channels (in-person, online, mobile)
  • Invoicing and recurring billing
  • Virtual Terminal
  • Data analytics and reporting
  • POS integrations

🎯 Key Differentiators
