Constellation Payments

Constellation Payments is an enterprise-grade payment processing company and a division of Constellation Software Inc., founded in 2012. The firm provides embedded payment solutions for software companies and other businesses across the United States and Canada, functioning as a payment technology partner within the Constellation Software ecosystem, including Jonas Group operating companies.

The company's principal product, the CSIPay Gateway, is a payment gateway platform that allows independent software vendor (ISV) partners to integrate payments directly into their applications, handling the full payment lifecycle while the partner retains control of the customer experience. It is accompanied by a PayFac as a Service offering, which lets software companies embed payments as payment facilitators without building the infrastructure themselves. The wider suite covers point-of-sale terminals and e-commerce payment solutions for online businesses.

The platform processes more than $3 billion in transaction volume and serves over 4,000 merchants, supporting more than 40 payment methods. Constellation Payments commits to a 99.9% uptime service-level agreement and holds PCI DSS Level 1 certification, the highest level of the payment card industry's security standard. Technical work spans payment processing, gateway integration, PayFac as a Service, e-commerce, point-of-sale, payment security and PCI DSS compliance.

Operations are concentrated in North America, serving software companies and ISVs alongside businesses in the Constellation Software portfolio. The stated emphasis is on payment solutions that are stable, secure and scalable, delivered to enterprise standards.
