I've decided to go with square.
There is a 2.75% charge for CC per swipe, with 1-2 day turnaround and deposit.
There is a 3.5% charge for CC non-swipe, with that same 1-2 day turnaround.
Using their all in one POS, which includes cash register, stand, ipad, ticket printer for the kitchen, and receipt printer, should be a thrifty alternative to a monthly POS.
It also gives the ability to analyze sales.
For accounting services, I've decided to go with an accountant and send square files to him :). I hope and think it will work well.
I'm not married to any particular service, but square, for now, seems to be the most convenient, streamlined, and cost-effective. Good luck, hope business is doing well.
