Built for eCommerce Software
eCommerce payment processing
for platform builders
CSIPay is the embedded payments platform for eCommerce and online retail software within the Constellation ecosystem. Hosted checkout, card not present processing, and recurring billing, all running inside your product.
Online, the checkout is the whole store.
Card not present commerce concentrates everything into one page. The checkout has to load fast, inspire enough trust to finish the sale, and keep raw card data away from your servers, because the moment card numbers touch your infrastructure, your PCI obligations multiply. Hosted checkout solves that: CSIPay hosts the payment fields, the sale completes inside your experience, and your platform's compliance scope stays small.
The second sale is where eCommerce economics live, and it depends on tokenization: the card is stored as a token after the first purchase, so returning customers and subscriptions charge without re entering a number. Building that vault, plus checkout, plus settlement reporting, is a payments company's roadmap. Embedding CSIPay makes it a feature of yours.
Everything an online platform needs behind the checkout.
Hosted checkout
CSIPay hosts the payment fields inside your checkout flow, keeping card data off your servers and PCI scope contained.
Tokenized cards on file
First purchases create secure tokens, so repeat purchases and subscriptions charge without re entry.
Card not present processing
Purpose built rails for online sales, in the US and Canada alike.
Subscriptions and repeat billing
Charge stored tokens on the schedule your platform defines for memberships and replenishment.
Security built in
PCI DSS Level 1 protection around the vault and every transaction.
Revenue for your platform
Online sales volume becomes platform revenue through our partnership and PayFac as a Service models.
The ecosystem's answer to online payments.
CSIPay is the embedded payments platform for Constellation Software and Jonas Group companies, so eCommerce enabled platforms in the ecosystem get online payments from a partner aligned with their model rather than a generic processor chasing every market. The relationship and the revenue stay inside the ecosystem.
The fundamentals are in place at scale: more than 4,000 merchants, PCI DSS Level 1 certification, a 99.9% uptime SLA, and full coverage across the US and Canada, including card not present payments in Canada, a detail that matters the day your platform's first Canadian merchant goes live.

eCommerce payment questions.
What is hosted checkout and why does it matter for PCI scope?
Hosted checkout means CSIPay serves the payment fields where card data is entered, so raw card numbers never pass through your platform's servers. That keeps the sale inside your user experience while sharply limiting the PCI compliance burden your platform carries.
How does tokenization work for repeat customers?
On the first purchase, the card is stored as a secure token in the CSIPay vault. Later purchases and subscription charges run against the token, so the customer never re enters the number and your platform never stores it.
Does CSIPay support card not present payments in Canada?
Yes. CSIPay processes card not present payments in both the US and Canada, so a platform can support online sellers on both sides of the border through one integration.
Can a platform run subscriptions on CSIPay?
Yes. Stored tokens can be charged on whatever schedule the platform defines, which supports subscriptions, memberships, and replenishment orders alongside one time checkout.
