Keep the frontend you chose.
Snipcart adds shopping-cart functionality to existing websites and supports physical and digital products. Its developer-oriented approach includes APIs and webhooks.
Penni Cart also connects to an existing frontend, with a Webflow app and a custom-code installation path. Choose the workflow your team can implement and maintain.

Compare a working checkout, not a promise.
Snipcart offers customization. Penni Cart lets you design supported checkout elements as part of your website. Build the same small purchase flow in each to understand the difference.
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.
Follow the purchase into your business.
Put order review, stock, shipping and recurring-purchase requirements into your evaluation. A successful payment is only part of a successful store.
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.
Test the actual gateway and product configuration you plan to use instead of assuming all processors behave the same way.

Inventory your products, identifiers, active subscriptions and outstanding orders. A new frontend connection is not an automatic migration of existing billing agreements or historical records.
Confirm what can be imported, keep the existing store available while testing and plan the cutover with support. Preserve search-visible product URLs wherever possible.
Questions, answered.
Can I reuse my existing website?
Yes, that is the intended Penni Cart approach. Replace or adapt commerce-specific integration points, then test products, cart and checkout on your actual frontend.
Will active Snipcart subscriptions migrate automatically?
Do not assume so. Saved payment references, recurring agreements and customer consent require a specific migration plan.
