See every featureThe in3 for Shopify app helps merchants communicate flexible payment options to customers early in the shopping process. It displays a message on the product page or shopping cart, informing customers that they can split their purchase into three payments. The app provides clear, early visibility into instalment options, enhancing the shopping experience and potentially increasing conversion rates.

It is an informational storefront widget only.
