Let's say you sell several products, that are all made from the same base product. You customise a part of the base product to make the customised product that a customer ordered.

You could be selling

You want to manage the inventory such that when 1 of the product sells, the inventory of all the products made from the same base product goes down.

There are 2 ways to do this in Sumtracker. You may choose any of the two ways, both are equally good.

When you assign same SKU to all such products, Sumtracker links all of the listings with 1 product in Sumtracker.

You will see the number of listings against a product in the Product list.

When you update the inventory of this SKU, the inventory of all your listings will be updated simultaneously.

When one of the product sells, the inventory of all other products will be adjusted by Sumtracker. This can take anywhere between 0 to 10 minutes depending on when the next sync is scheduled.

You can also have different SKUs for your products. You'll need to define bundles such that inventory of the customised products depend on a single base product.

With this, you will just have to maintain the inventory of base product in Sumtracker. The inventory of all customised products will be automatically adjusted.

Let's take an example. Let's say you sell t-shirts with different designs. You add a design to a black t-shirt after receiving the order for a South beach design, Utopia design or JJ90 design for instance. So you basically carry the inventory of just the black t-shirts.

In this case, you will define bundles in Sumtracker such that inventory of all the design t-shirts depend on the black t-shirt. You will have to define the bundle of each design t-shirt separately.

Here are screenshots of the bundles from Sumtracker.
