Your website. Your tools. One connected store.
Connect payments, shipping and everyday workflows to the commerce experience you build with Penni Cart.
Stripe
Provider-secure checkout for Webflow and custom-coded websites.
ExploreSquare
Connect a Square account for one-time online purchases.
ExploreShippo
Bring live shipping rates, labels and tracking into your order workflow.
ExploreZapier
Use supported store events to start workflows in your other tools.
ExploreGet paid without rebuilding your website.
Choose the supported payment provider that fits your business. Penni Cart connects the shopper experience to your store’s selected gateway, with separate test and live credentials.
Stripe and Square use their own secure payment fields. You can design the checkout around those fields, while the provider controls sensitive card entry. Available payment methods depend on your account, country, currency and the released Penni Cart integration.

A purchase is only the beginning.
Offer shipping options that match your products and destination coverage. Shippo adds carrier rates and label workflows; configured flat and zone rates remain useful for local delivery or predictable shipping.
Carrier availability, postage and eligibility come from the connected shipping account.
Give every order a next step.
Supported Zapier events can send order information into the tools your team already uses. Build a workflow with a clear trigger and a tested destination rather than copying customer details by hand.
Verify the available event fields and your destination app before enabling an automation.
Connect first. Test before you launch.
Start with a test store and the website you already have. Connect the integration, complete a checkout and confirm the resulting order before accepting live purchases.
Check your website plan, Penni Cart entitlement and provider account separately. Free signup is a way to start building; it does not make every production website or payment transaction free.
Questions, answered.
Can I use these integrations on a custom-coded website?
Yes. Payments and store operations connect through Penni Cart, while your frontend uses the current SDK installation and commerce attributes. Follow the custom-code quickstart and test the complete checkout.
Does every gateway support subscriptions?
Recurring product renewals currently have Stripe and Converge processing paths. Square is a one-time checkout option, not a supported recurring-renewal processor. Confirm saved payment references and a complete renewal test before launching subscriptions.
