Built for Veterinary Clinics

Veterinary practices face unique payment challenges:

  • High average ticket sizes

  • Card-not-present transactions

We support secure mobile, in-clinic, and online payments that simplify billing and improve the client experience — without disrupting workflow.

Turn Processing Costs Into a Margin Advantage

Healthcare practices process high ticket amounts — and card fees add up quickly.
We offer compliant Dual Pricing solutions designed to offset rising processing costs transparently, without increasing listed service fees across the board.
Clear pricing. Patient choice. No hidden fees.


For dental and veterinary practices especially, where treatment plans and procedures can be significant, protecting 3–4% in margin can make a meaningful difference.

Our structured approach focuses on:

  • Clear pricing at checkout
  • Customer choice
  • Regulatory compliance
  • No hidden fees

Protect your profit without raising prices across the board — and without hidden fees or surprise increases.
