No there isn’t! Invite multipe database users (free of charge!) in order to collaborate with your team.

Multi-user in free Limited version:

Invite your colleagues to participate. No strings attached, no credit cards required. You can set all of this up including multiple users connecting to a shared database as part of the free Limited edition to be sure you are happy with it before you purchase any licenses.

You can add more users at any time by installing SpinOffice on additional client PCs or Macs and go to menu option New > Invite database user to invite them within your database.

Multi-user in your Pro account:

Go to right top corner button 'Manage licenses' to see all active users and licenses. Each invited user will be billed as additional Pro license.
