Anyone here use Square as their point-of-sale system? I'm taking ownership of my family business and the system in place is very outdated. I'm looking for an upgrade that will allow staff to interface with customers and handle certain types of transactions from any location in our retail facility. I'd like to provide each employee with a tablet that allows them to process payments, track and manage inventory, etc.

This seems to be an option with no upfront costs, which I find too good to be true. Where do the hidden costs come in? How much am I going to get from this "free" service before I start getting hit with fees? I've been looking into a bunch of POS systems and am not interested in a full head to toe revamp at this time, which is what a lot of POS companies try to sell, and the cost is astronomical. Maybe worth it down the line, but for now, I just want a simpler solution that will meet my basic needs.

I read some reviews that Square may not be the best platform for handling large volumes of sales/transactions - can anyone validate this? Would it be recommended to use the square debit card/checking account that is offered, or link my already existing business/checking account?

Looking for low-cost efficiency with my main priority being inventory management - which is something that the business does not have a good handle on right now. If there is another system that anyone could recommend instead of Square, I am all ears!
