Timesheet autolock in NeetoInvoice stops team members from adding or editing time entries once a period closes. You enable this timesheet lock per project and pick one of three rules: end of the day, which allows a 24-hour grace period, or end of the week or end of the month, which lock the previous period with no grace period.
It suits agencies and consultancies that bill on a fixed schedule. If you invoice a client every Monday for last week's work, a weekly lock keeps those hours from changing after the invoice goes out. People you grant override access can still correct locked timesheets, and the autolock override report shows who made the change, for which user, on what date, and whether an entry was created or edited.
