Unit of measure

Creating and deleting UOMs

EVA supports custom units of measure (UOM). This allows you to make your own custom packages, pallets, etc. with a specific number of products contained in it, making it much easier to scan and receive goods.

The way EVA handles UOMs is by first creating the UOM itself and afterwards tying it to products. This means there's no UOM in EVA that holds a strict quantity, but instead a UOM versus a product.

This page will go over its front-end usage, but you can also manage UOMs via API directly.


Creating a UOM

We first create the UOM itself, which comes down to the General details you can see in the image below. These are the details that will be displayed in the overview.

Afterwards, you can start adding products. The addition of products via the product modal is as straightforward as you can expect in EVA, but with one little caveat: only a single product can be added at a time. You can add the Quantity and Barcode of product to be included in the UOM directly.


Employees are notified if a duplicate barcode is entered, along with information about the item it was previously associated with.

After saving the product and its quantity, you can add as many new products as you like.


You can edit and update General details by pressing the "pencil" icon at the top right corner of the card. Similarly, for editing products, you can use the same icon on right end of each product line.

Using UOMs directly in ImportProducts

Now that you've created a UOM, you can also use it in the ImportProducts call directly: you can add the UnitOfMeasureID and specify a Barcode and the Quantity it contains. This way you can skip the steps below.

Deleting a UOM

To delete a UOM, click on the existing UOM displayed in the overview. At the bottom left corner, you will find a "Delete" button.
