employee details
There should be an audit trail in Payroll detailing when changes to an Employee record is made (for example: date an address was updated for an employee and what it was until that date, likewise for other details such as email address, bank account number, tax code etc). As an Employer we should be able to rely on the digitised Payroll system we are using to determine when changes to an Employee's record has been made. In terms of creating an audit trail, this doesn't necessarily only apply to Payroll only and should ideally be something that is normal and embedded right across the platform, however when it comes to Payroll and employees, this basic functionality would be extremely useful in the event of HR/Employment issues or even when dealing with Inland Revenue regarding an employee's details.
