You will use the External ID when exporting ClickTime timesheet or time‑attendance data to third‑party payroll or accounting systems such as:
MYOB
KeyPay
ADP
Other integrated platforms
To avoid import errors in your payroll or accounting software, make sure that:
The Site / Job Card ID or External ID in your other system matches exactly the External ID you enter in ClickTime.
This matching allows ClickTime to generate an export file that your payroll system can read and import correctly.
