Yes, the multi-user mode in QuickBooks Pro allows multiple users to collaborate on the same company file at the same time. All users must be networked and must each have their own QuickBooks license. The standard QuickBooks Pro license lets you install the product on up to 3 computers. It also has a multi-company feature. Note that one license is required for each user. A server does not count as a user if no one will be accessing the QuickBooks on the server itself.
