I own a small business and we have experimented with Square Register and other ipad-based POS systems. Register is by far the least feature rich of all of the offerings we looked at - this is not necessarily a bad thing. Specifically, Cons * Register is not designed for restaurant use - many of these reasons have already been discussed on this thread, the biggest being the lack of modifier support. * Register does not support weight-based pricing (delis, produce, etc). * Getting meaningful data out of Register is annoying * There really isn't much tech support for Register - for a lot of businesses, being able to pay somebody to come set-up a POS and train the staff is a real feature. * The card reader is unreliable - multiple swipes are often required. (A non-free, durable and reliable card reader would be a good thing for Square to consider offering). * No inventory management. (If there was a nice API, other people could solve this problem.) Pros * It provides a nicely unified experience across Register and Wallet, which makes enabling Wallet easy. * Square is still our preferred payment processor for credit card transactions. I especially appreciate how they transfer money into our bank account within 24 hours instead of trying to justify why they should be allowed to hold on to it until the end of the month. * It is the easiest to set-up and use, and to train employees to use. In terms of the ipad POS space, none of them are really mature POS systems yet. If your transaction set is simple, or if you're willing to modify it to fit into the POS feature-set, then one of them is probably right for you. If you need Aloha-style customizability, you should wait. My guess is that different POS solutions will generate traction in different markets, and then it will become much clearer with solution is right for your business. Personally, I think the old-style POS's are such a rip-off that figuring out how to make your small business work with a newer technology is worth it. Running a food business, however, I would not recommend Register. If I ran a business with a simpler item set (e.g. a clothing store), then I would seriously consider it. Asides * Yeah, those printers are like tanks. Two thumbs up! * You definitely want physical security. The bundled stand includes the ability to secure against grab-and-go theft (http://hecklerdesign.com/windfall/ http://hecklerdesign.com/windfall/). (edit: formatting)
