You might not want Core to evaluate and mark your time entries as non-billable when the amount spent on the project goes over the contract for Fixed Fee project types. In case you want to keep all the time entries on a fixed project as billable even though the amount spent on it is greater than the contract amount, this is possible in Core although by default Core performs the automatic time and expense entry evaluation.
To resolve this on a project level in Core:
- Go to the Projects screen > General > Rules & Contacts.
- Click Add Rule and check the 'Skip automatic time entry evaluation' rule. This allows you to enter billable time over the contract for time entries.
- If you want to globally update all the projects for this rule, go to Global Settings > Time & Expenses section and check this rule there.
