Other than hardware which is based on iOS nothing else is good. If you're looking this POS for your Liquor store then I would say don't even think of buying this crap. Its good for a coffee shop, small clothing store, any business which have 100-200 SKU's. Customer service was good until I informed the sales rep about my business needs about the liquor store is very specific and it has to be in macro details. This POS miss out on many things such as on startup it would not ask you who is logging in (if you have multiple employees) It will not ask you what's the cash drawer opening balance for today. Adding an item is a headache specially if you have 1 item which has multiple variations for example Modelo beer 30 pack, 24 pack, 12 pack, 6 pack or singles. upon adding an item it doesnt give you a Distributor Code which is very important for a liquor store to have. Theres no such thing where you can view the past invoices and add invoices upon receiving the delivery. The sales rep upon signing up showed a different transaction rates and later when i figured it out it was way above what he promised. This POS doesnt even have live push notifications on the app most of the other Liquor POS have this feature which gives the owner peace of mine. For example if the product was added to cart and the employee deletes it then why was it deleted what was the reason? this pos doesn't have any such thing. The main screen is kind of small since its actually an ipad and the customer facing screen is also the same too small. I would not recommend this POS until they reach their mark with other liquor POS have to offer. Good Luck to Square and its sales team.
