Our business has been using quickbooks online now for 5 years. Everything is done by the bookkeeper as for as entering daily sales, account receiviable etc. I am looking to change that by finding a point of sale system that I can replace our antiquated cash register and hand written invoices with. I understand that quickbooks own Point of sale system does not integrate with online quickbooks. What point of sale system works best with quickbooks online? Do you have any recommendations? Thanks!
