I am disappointed I will now have to pay for features I do not use just to keep the few I do use. Here is a feature I need that is currently not available on PRO but should be.
I cannot partially fulfill an order for in-store pick up. I can if the items are being shipped, but not if the customer is local. If a customer pre orders a holiday item plus adds in stock items to their cart, I cannot fill only the in-stock items and leave the holiday item as partially filled like you can when an item ships.
I am sad Shopify is making the change during our busy season. Please wait until February when retail is slower. I really cannot absorb the additional fees this year. Your timing could be better.

I'm disappointed we're having to switch over to a paid POS system just to retain the existing functionality offered with the previous App. It wouldn't be so bad if we were getting more value out of it but, none of the features they've introduced are particularly useful in a retail setting. I would happily trade in the ability to customize my home screen for the ability to process refunds in a practical manner. I hesitate to say but, it even appears that we will be losing value from the time it's going to take to parse out all of the nuanced differences and retrain my staff. Navigation in general is not intuitive for users of the previous app. The verbiage has for the most part completely changed and is not in-line with the standards set by other POS systems. The cashout is confusing. All in all, it seems like a product designed by software engineers for software engineers and not retail salespeople. If you are in a situation where you do not need to rely on the Shopify POS for inventory management I would not recommend it. As of 10/17/2020 - Back with more observations... The product search is indexed is completely differently from the previous POS and the shopify online store App. For example: Searching for a popular product we sell called "Delice" now pulls up search results for every single item on our online store with the word "delicate" in the description. For most use cases this sort of thing is probably pretty edge but we have hundreds of SKUs and delicate is a pretty common adjective in the wine/fine food industry. There is also a relatively significant delay in applying tax to the total cost of sales which is leading to a lot of cash out errors during peak periods. Also note none of your configuration from the previous version of the app (such as payment method settings) will carry over. Between the new monthly cost and the time I'm spending retraining/figuring out how to make this version of the POS function at the same level of efficiency as the previous one I'm definitely losing money. Downgrading my review to 1 star. Will be switching as soon as I figure out how to manage my inventory without it.

We had POS classic system for years which suited our business perfectly. I recently switched to the POS Pro Trial due to Classic being obsolete soon so I could re-train my staff now Shopify want $89/ month / terminal. WTF I have 4 stores that will cost me a fortune. If they charged $89/ month ONLY I would have signed up but at $356/month US to AUD it's $496/month sorry but absolutely no way. Now I have reverted back to POS Lite and this thing now is totally inadequate for my business they basically ripped all the features out of POS Classic and put it into POS Pro just so you have to pay for it now. Exchange button GONE,
Save the cart GONE. Staff Permissions GONE.
Sorry Shopify you screwed up a very good product just to make more revenue out of small businesses. Unless you revert back I will be serching for a new POS system ASAP.
