Virtual Terminal & Online Payment Gateway
Accept payments online or over the phone with a built-in virtual terminal and gateway — no separate hardware required.
Common Challenges
- Accepting phone orders requires a separate terminal setup that ties up counter space
- Managing recurring clients means re-entering card data manually every billing cycle
- Shopping cart and accounting integrations break when gateways don't support open APIs
- B2B card transactions get downgraded to expensive non-qualified rates without Level 2/3 data
