In case you have not already heard, Intuit and Revel Systems have announced a partnership that will result in the companies jointly releasing a new point of system sometime in 2015. Initial indications are that the new point of sale system will be iPad based and designed to work with the online version of QuickBooks Online Accounting.
No specific details are available related to cost or final release date but I will keep an eye out for more details and pass them along as time permits.
