If you're paying staff that are on an Award, then you should review KeyPay.
Processing payroll can be quite complex and sensitive.
You need to have exceptional systems to ensure the accuracy of pays, rather than having outstanding payroll officers who have all the data and knowledge in their heads.
Suppose you're reliant on the payroll officer.
In that case, you could come unstuck when they take Annual/sick leave or resign from the business. The person filling in may interpret the award differently, meaning a different pay outcome for the employees.
If they resign, all of the payroll knowledge leaves with them. You'll be back at square one.
