To set up your account properly you will need to create your branch(es) first, then your groups and at last your users.
Via 'Settings' - 'Company Settings' - 'Branches' you can divide your company in the needed entities, with an enterprise number. Xpenditure has set up one default branch for you already. You can easily overwrite and complete the data with the correct branch information, by clicking on the branch-line.
If you need more than one branch you can add them by clicking on the green button 'Add branch'.
!Be careful, it is not possible to delete branches!
