Sometimes multiple people in one company need access to the same QuickBooks file at the same time. If this need pertains to your business, you’ll need to have at least two QuickBooks licenses: one for each person simultaneously accessing the company file. If you need to purchase a QuickBooks license, let us know!
Once you have the additional licenses, you can set up a second computer to see the first through a wireless or wired network. Once the computers are linked by the network, share the database with both Windows users. On the computer you accessed QuickBooks first, go to Help>Manage My License>Sync License Data Online, so that the original license now sees you have a second license attached to it. Also you will have to switch to multi-user mode by going to File>Switch to Multi User Mode.
