Interesting - I've had a few stores contact me to let me know that they recently stopped using ShopKeep. LightSpeed or Revel and have switched to Bindo point of sale. I'm not sure on all the details but obviously something happened which was big enough to make these retail owners stop using their current point of sale systems.
I have had complaints in the past about Revel sometimes locking up when swiping a credit card as payment and past complaints about ShopKeeps tax setup - not sure if that applies in these cases or not. I'll be sure to pass along details if I get a chance to talk to any of these businesses.
I'd say things bode very well for Bindo! More reviews on Bindo POS can be found here: https://bindopos.com/reviews
