The app was often extremely slow to open. I had to open it before serving customers or refilling products that were sold by weight, otherwise people had to wait a long time. Many customers stood around while the app tried to load. I do not recommend it. To be fair it works if you have time to wait for the app to open..

When it works it works fine, and gets the job done. That's when it actually works, I've had a lot of times where the app just doesn't load at all. Very frustrating, I don't like that it does not track inventory either. I run a refinery so I need to be able to charge by the ounce and this was really the only option, I wish Shopify itself would allow to charge by ounce directly in the POS. If this was a free app I wouldn't be complaining, but the fact I pay every month for it and half the time it doesn't load up just sucks.

App is too slow to use. Would be better if you could use it for online store not just POS. Also does not sync inventory or can show you data analytics on your products. It uses a quicksale checkout. It looks like I haven't sold a product in so long, but I've just been selling via Unitpricer. They say analytics are available by opening each individual products and opening the app, but my reports are completely empty. I do love the concept but the app ultimately takes too long and makes for an awkward customer interaction.

We have been trying to find an app that allows us to sell items that are priced by the pound at our POS. Since Shopify doesn't currently allow you to enter an item and have the POS prompt you for the price we needed to find an app that allows us to adjust the price...and not just apply a discount Unitpricer seemed to meet those needs, however, the app adds tax to items that don't currently have tax enabled. We sell apples by the pound which does not require tax. In order to sell that product we have to... 1. Weigh the item on a separate scale 2. Enter the price per pound on that scale to get the sale price 3. Select the item in Shopify 4. Select Unitpricer 5. Adjust the price to match the price on the scale 6. Remove tax from that item after unitpricer adds it back in While I'm happy to have an option to be able to sell my products, the speed of unitpricer as well as the fact that it adds tax on an non tax item is an issue. I'm worried that one of my staff will not catch this and will upset a customer upon looking at their receipt. Overall a good app, just may not be the best option for those looking for speed or selling items with that don't require tax. UPDATE Thank you Unitpricer for your response. Unfortunately, most of the items in our store require tax. It would take much more of an effort to take tax off of all the other items we sell versus just a few specific items. Thank you for providing a solution, I'm sure my situation is different than most. I am in agreement with you that this seems like a pretty logical thing to address in a shopify POS update. I'm sure it will be along at some point, just a frustration as of now.

I am over the moon excited about the functionality of this app. It was very easy to install and integrate into my existing POS system. Customer service was almost immediate when I had some questions and we resolved them quickly.

I wish the app was around when I launched our store. We sell a range of meat cuts per gram and previously we had to have the products listed in our POS as the price per gram. This meant at checkout a single packet would have to have a qty equal to the packets total grams. Unit price cleans all this up and lists products correctly on the receipt. It will also enable us to use inventory per piece because we will no longer have to use that to calculate the price. Currently, you can only add a single identical product one at a time, But I reached out to support Daniel got back to me in minutes and informed me he will look at fixing this in a future update. Highly recommend this app to all stores using Shopify POS who need to sell by weight.
