Every site you build needs payments. Earn for the life of every account.
You already wire up Stripe or PayPal on every client site. Swap in CoreGateway and the same build pays you a monthly residual on every transaction your client processes - for as long as their site is live.

The recurring revenue line your agency does not have yet.
Most agencies bill the build, then walk away. Bundling CoreGateway means every site you ship continues paying you for as long as it accepts payments.
Lifetime residual per client
Every client site you build with CoreGateway pays you monthly residual for as long as it processes. Not a one-time bounty - a compounding book of recurring revenue tied to the work you already do.
Hosted Payment Page
Drop-in branded checkout in minutes - perfect for WordPress, Webflow, and custom sites. SAQ A PCI scope keeps your client off the compliance hook. No JS to maintain.
REST API for deeper builds
For custom checkouts, marketplaces, and headless commerce - clean REST + JSON, sandbox keys, developer guide. No XML, no SOAP, no legacy gateway weirdness.
Recurring billing + Card Updater included
If your client charges subscriptions or payment plans, you can ship the recurring flow on the same gateway. The Automatic Card Updater prevents revenue loss when client cards expire.
Lower client fees than flat-rate
CoreGateway uses interchange-plus pricing. Your client can pay less than a flat-rate processor once volume picks up - which means they thank you for the build instead of complaining about the fees.
Dedicated integration support
Real humans on the partner team. Your developer questions get answered. Your client onboarding questions get answered. No ticket-queue gauntlet to navigate.
The client sites where this is a no-brainer.
If you build any of these, CoreGateway slots into the deliverable with zero extra friction. The integration is the same project work you would do anyway.
Custom service business sites
Lawyers, consultants, contractors, agencies, salons - your client takes invoices and deposits. Hosted Payment Page + invoicing covers the whole flow.
Membership & subscription sites
Gyms, clubs, learning platforms, content sites. Recurring billing + customer vault + Card Updater - all in the gateway, no Stripe billing plugin required.
