This app is complete dogshit. You dont need it. To run a tab, just create a customer, add customer to cart then save the cart. You can pull the cart up and add to it or checkout thereafter.
The client is correct in that you do not need the app __if you only utilise a single tablet in your establishment__
If however you have multiple tablets, and you need to recall a Cart on any tablet, the standard Shopify functionality will not let you recall a Cart on any other tablet. You will need an app such as UbarTab to support such requirements.
UbarTab also handles real-time inventory tracking when placing items onto a Tab, thus ensuring your inventory is correctly tracked across multiple Tabs and devices.
It seems like this app is not working with the new version of Shopify POS App. It needs to be updated
Apologies for the inconvenience. The app does work for the new version but the documentation is outdated. If you decide to try the app again, please reach out and I will be happy to provide a guide that will get you started.
