# Linked products

**Flow Retail supports linking various types of products to a specific product, like accessories or spare parts.**

This is super-handy for remembering to recommend relevant accessories to the customer.

With the Auto-Add link type you can also *automatically* add a product to the order based upon another product. This is extra handy when selling for example soda/drinks and wanting to add a bottle deposit fee product, or some other type of fee related to a specific product, like enviromental fee, etc.

## How do I add linked products to a product?

Simply go to the relevant product in Backoffice, and find the <kbd>Linked products</kbd> tab. Here you can add the various linked products as you want.

## What are the different product link types?
