Cartfunnel is a checkout page system for your existing Shopify store.
You’ll be able to — in a single application — extend your existing shop’s functionality with features that are not available with Shopify or otherwise require the use of multiple apps and/or custom integrations.
How Cartfunnel works

Our integration allows your customers to use Cartfunnel’s checkout system during the checkout process. You can decide, with the help of some custom coding, to allow all orders to flow through Cartfunnel or just the ones that require the extra functionalities (eg. recurring billing) provided by our application.
This integration requires several minor changes to your existing theme, which we’ll cover in the Installing Cartfunnel to Shopify section.
Your shop’s products are synchronized to Cartfunnel, including any pictures, titles, variant titles, and prices.
As orders are received, they are exported to Shopify where you can continue to leverage your existing business workflows and other features and applications that you use for order fulfillment.
Abandoned cart email sequences are built in to Cartfunnel, as well as email confirmations for orders received. You can optionally turn these off and use the existing functionalities provided within your store.
