We use Quickbooks Pro for my construction company at present. We have opened up two offices in other parts of the state and now have three location. I need to connect my people and am looking at Quickbooks Online but have been told by one of my people that is much more efficient at computing that the service is slow?
Speed of the product will depend mostly on the speed of your available internet at each location. You can take a test drive on a free trial.
The big advantage of QBO for multiple locations is that you only need 1 subscription for 1 or up to 5 users plus 2 accountants all at same price. For the product you have now you need to buy a license for each location computer you use plus cost of hosting the company file unless you self host. In addition desktop software cannot be easily used in the field, whereas you can access QBO from any internet device including phones and tablets.
