QuickBooks Pro Hosting uses QuickBooks Pro on a cloud server hosted by a third-party vendor. The quick reference is "familiar," to which the third-party vendor will provide the user with a data location URL that they will reference when logging in to their hosted server. Essentially, the user is running the prepaid software, QuickBooks Pro, on a server in the cloud, accessed via the internet. It offers everything that is provided in QuickBooks Pro desktop and all the benefits of the cloud. Potentially, you have up to 25 users logged in simultaneously, working in real-time on one collaborative project. Also, depending on the hosting provider, it is possible to have your data backed up, have security safeguards, and if there are any IT issues, most hosting providers have IT support to assist with your access.
