Marketplaces and stores, all agent-shoppable.
CS-Cart is the platform of choice for independent operators running anything from a single store to a multi-vendor marketplace. xpay reads your CS-Cart admin, publishes a clean AI feed to ChatGPT, Gemini, Claude, and Perplexity, and routes purchases back into your existing checkout. Storefronts, themes, and payment methods stay exactly as you have them.

People are asking ChatGPT and Google what to buy instead of searching. Those AIs answer — but they don't send buyers to your store. The brands listed inside those AIs make the sale. Everyone else watches.

Your customers are asking AI "what's the best yoga mat?" or "find me a birthday gift under $50." If your products aren't inside those AI assistants, you're invisible to your next customer.
Customer asks ChatGPT for a product recommendation. Your brand doesn't show up. Someone else gets the sale.
Google Gemini answers the shopping question — but sends buyers to bigger brands who are already in the system.
With xpay: your products appear inside ChatGPT, Gemini, and 4 other AI assistants — and the buyer pays you directly.
The right shape for the platform you already run.
CS-Cart is one of the few platforms where you can spin up a single-vendor store today and a full multi-vendor marketplace tomorrow without changing stacks. That flexibility is also what makes channel expansion painful — every new surface has to handle both store and marketplace operating modes. xpay handles both. The add-on installs in the standard admin, treats single storefronts and Multi-Vendor marketplaces alike, and lets you opt in vendors progressively. AI buyers researching across ChatGPT, Gemini, Claude, and Perplexity start seeing your catalog with the right pricing and storefront branding. Your checkout, payment add-ons, and vendor payout flows stay exactly as they are.
