Unit Tare App | Get Net Weight

Weigh the products not the containers. Achieve net product weight.

Why Use the Unit Tare App? If not to get net weight?

Because it offers tare functionality for CAS SW-20 Connected Scale.

Clover works with CAS SW-20 Wired Scale; the scale weighs anything that's placed on it.
Sometimes merchants need to deduct the weight of the container and it's not quite possible to separate the container from the product due to packaging or the nature of the product. In this case, merchants can use the Unit Tare app to remove the weight of predefined containers from weight based items in the current transaction.

Interacts with other software
The Unit Tare App works with CorePOS to automatically deduct container weight at checkout. Merchants can set up tare values in inventory or during transactions, ensuring accurate pricing for weight-based items and a smoother checkout experience.
When the register is started and weight based items are placed onto it, the Unit Tare App will engage and execute its function based on the merchant's configured settings.. This includes asking merchants to select from the list of containers and apply these containers to the items in the cart.
The Unit Tare app is capable of distinguishing between fixed price items, which it ignores, and weight-based items or Per Unit Items in the Clover Inventory app. When the item selected is per unit, Unit Tare will execute its function.
