Inventory count

Shopify Apps

Hi,

I want an app to help me manage my inventory. My only problem is I sell personalised products, so one product might need A, B, C inventory, and the other product needs A, D, E inventory. I want an app that when a customer orders one product, the inventory needed for that product automatically reduces so I know when I have to stock up.

Hi @shopbusiness12 ,

Material Manager is able to do this. In the app you would enter A, B, C, D and E as raw materials and set their inventory numbers. Then you would link product 1 to A, B, C and product 2 to A, D, E. Your Shopify inventory will be set to the maximum that can be made based on the materials in the product.

For example when you sell product one it will decrease the inventory of A, B and C. Since product 2 also uses A it’s inventory will be reduced as well.

Hi @shopbusiness12 ,

The Easify Inventory Sync app can streamline your inventory management. Here’s a quick setup guide to help solve your challenges :hugs: :

  1. Set Up Individual Products: Create products A, B, C, D, E, etc., each with their specific inventory.

  2. Create Bundle Groups:

    • For Product 1, which requires A, B, and C, create a Bundle Group. Set Product 1 as the Master product and add A, B, and C as component products. Specify the quantity per bundle for each component (A, B, C).
    • Similarly, for Product 2, which requires A, D, and E, create a second Bundle Group with Product 2 as the Master product.

How It Works:

  • When Product 1 or Product 2 is purchased, the app will automatically deduct the inventory of the included products (A, B, C, etc.) based on the quantities required per bundle.
  • In addition, the available inventory of A, B, C, etc., will also determine the number of Product 1 and Product 2 bundles available for sale.

If you’d like to try the app or need step-by-step setup guidance, feel free to reach out, or contact the Easify team for quick assistance.

Hi @shopbusiness12,

The part of this that trips people up is that A is shared. Product 1 pulls A, B, C and Product 2 pulls A, D, E — so a sale of either one has to move A, and both products’ availability has to be recalculated from whatever A has left. Whatever you use needs to handle a component sitting in more than one recipe, not just one product holding a private list of parts.

The setup pattern, whichever app you land on:

  1. Create A through E as their own products or variants, put the real stock on each, and hide them from every sales channel. They’re inventory records — nobody buys them directly.
  2. Define each sellable product as a set: Product 1 → A, B, C with the quantity of each it consumes. Product 2 → A, D, E the same way.
  3. On an order, the components drop by the right amounts and the sellable products’ availability is recalculated from what’s left.

Four things worth asking any vendor before you commit:

Can one component belong to several products at once? And when A’s stock changes, do both Product 1 and Product 2 update? For your setup this is the whole ballgame — if the answer is no, nothing else about the app matters.

Does it deduct at order placed or at fulfilment? For personalised items those are different moments and it affects what your available-to-sell shows while a job is in progress.

Do the component quantities take decimals? Only matters if any of A–E is measured rather than counted — 0.4 of a bottle, 1.5m of ribbon. If it’s all discrete items, ignore this one.

Does restocking a component push availability back up on its own? Or do you go and edit every affected product by hand when a delivery lands.

Disclosure: I build one of these apps (Invento: Virtual Inventory Pro), so factor that in — the setup above is the same whichever one you choose. Ours handles this shape, takes decimal quantities where you need them, prices by Shopify plan and has a free trial: Invento: Virtual Inventory Pro - Keep raw material, bundle, kit and combo inventory in sync | Shopify App Store

One honest note: if this is two or three products with a handful of components, a spreadsheet holds up fine and you’d be paying for convenience. It starts genuinely earning its keep once the recipes overlap enough that you can’t keep them straight in your head.
