The Final Payslip option is used to pay out the employees leave balances if required when they leave the business. We suggest processing a normal payslip if any regular hours worked to pay out for the employee. Then you would need to process another payslip to pay out the entitlements for the employee.
Once you have pressed the 'Save & Send' button, the leave balances will be zeroed out.
