When switching to Timebutler, you may want to import previously recorded time entries into Timebutler.
Timebutler intentionally does not offer a bulk import for time entries, because importing old time entries is not necessary. Here is why:
When you enable time tracking in Timebutler, you set the date from which time tracking starts. You can also set an initial overtime balance for each employee as of that date. Employees then start on the configured date with their entered starting balance. Time entries recorded before that start date are not relevant in Timebutler and do not need to be entered or imported.
Read here how to set the start date for time tracking and the initial overtime balance for employees.
