Set Up Inventory ​

Inventory is the shared product and stock source for Merchant Stack.

Use Inventory so the merchant does not maintain separate product lists in TPoS, WebShop, and other sales channels.

Why use Inventory ​

Inventory helps merchants:

  • create products once
  • reuse products across extensions
  • track stock quantities
  • store product names, descriptions, tags, and prices
  • separate in-store and online products with tags
  • keep checkout and WebShop data consistent

Basic setup ​

  1. Enable the Inventory extension.
  2. Create an item.
  3. Add a name, price, description, and any useful metadata.
  4. Set stock quantity.
  5. Add tags or categories.
  6. Save the item.

Suggested product fields ​

For each product, collect:

  • product name
  • short description
  • price
  • image
  • stock quantity
  • category or tag
  • weight if the item may be shipped
  • channel tag such as pos, webshop, or event

Channel tags ​

Tags are useful when the merchant sells different products in different places.

Examples:

TagUse
