How long does recommendation generation take?

Frequently Bought Together builds automatic recommendations using your sales history. After installation, the app starts gathering product and orders data from your store using the Shopify API.

You can see the percentage of orders processed in the app preferences page, under Global information:

This percentage will reach 100% when all your orders are processed and all the recommendations are built. This process might take some minutes to be completed, usually less than one hour, but it completely depends on how big your sales history is and on Shopify API. Anyway, in most cases, the app will be able to display some recommendations in just a few seconds after installation.
