About Quantum Gateway

Powering payments since 2006

Quantum Gateway is a product of CDGcommerce, providing reliable, secure, and developer-friendly payment processing for over 20 years.

Built for reliability

Quantum Gateway was created with a straightforward goal: make payment processing reliable, secure, and easy to integrate. While other gateways have come and gone, QGW has been a steady partner for merchants since 2006.

As a CDGcommerce product, we combine enterprise-grade infrastructure with the personal service of a company that knows its merchants by name. Our support team is US-based, available 24/7, and actually understands payments.

We offer five distinct integration methods — from fully transparent server-to-server APIs to simple embeddable forms — so you can choose the approach that fits your technical needs.
