UbarTab

Absolutely spectacular, simply app that we use daily. Support was absolutely incredible with response time and even added functionality that we need. We are actually using this not for a bar tab but for our stores guitar technician to help keep track of orders, so there is more than one use of just bar tabs - great for any application that you need to save carts for any amount of time!!

It's great! Not too deep. Simple interface and well thought out. Even my Jpn staff can use it. No documentation though so not sure about a few things about Tab Update".

We're a fabric store and we use the app to cut fabric at one register and save the customer's cart. They can keep shopping and then checkout at another register.
I just wish that the app would automatically release inventory when loading a cart (Instead of offering you the choice to keep the hold). This might not matter for some use cases and probably doesn't for restaurants, but for a retail store we think having the option is strange. It isn't a big deal, we just don't use the option.
Great app and the only one that way to easily start an invoice on one device and finish it on another.

It seems like this app is not working with the new version of Shopify POS App. It needs to be updated

This app helps to plug a big hole in Shopify. The in person POS setup for Shopify doesn't manage the typical way a bar or restaurant does sales, with payment at the end of the night (which tends to increase tips if we're doing our job right). We considered abandoning Shopify, despite the online sales presence, because of this.
This app allows us to manage tabs - it takes a few extra clicks, but it is serviceable, and works well. The high rating is because there is no other app that does this in Shopify and saved us from having to completely redesign our web presence. I would argue that this should be part of the base Shopify product.
Some weird interactions that I think could be cleaned up. When you open a tab, it clears the cart - this is good. When you update the cart it doesn't clear the cart, which can create some confusion.
We've added a button on the tabs POS screen of add customer and have a number of customers for Table 1, Table 2, Patio 1, Patio 2 ... The notes field helps because we can associate a name to the table.
The split function is nice. I would add a radio button in the dialog to indicate which split tab becomes the active cart after the split.
Oh, and the benefit of being able to pull a tab from one device to another is a huge plus, allowing us to consider taking orders on our own individual devices and leaving it on a tab.
An additional function I would love to see is the ability to print a tab, both so we can remember when the bar gets busy, and so we can use it as a bill for the customer.
Thanks for this product.
