Base hourly rate auto-calculating incorrectly

Base hourly rate is auto-calculating differently to what it should be based on the employee pay rate.

No consistency between which employee, which pay run, or the amount of miscalculation.

Has been occurring seemingly randomly over a period of several months (that we have detected so far). The result is underpayment of affected staff.

We have spent 1.5 hours on the phone with MYOB customer support today, which frustratingly has provided no explanation of cause nor solution to prevent this happening in future - after some time looking into it over the phone and remotely the MYOB support person suggested in the end that it is 'a glitch' and could not give any assurance that it won't continue happening.

This error renders the payroll software extremely unreliable...it is unfit for purpose with this happening.

We request URGENT resolution to this problem please as underpayment of staff is obviously not acceptable.

Additional info: We are running three separate MYOB Accountright files for the three branches of our business...all payroll payments are processed by the same staff. This error is only occurring in ONE of our Accountright files (payroll payments made in the other two business files appear to be unaffected).

Again, we request urgent investigation and resolution please as it is vital that a payroll software calculates employee pays correctly, which it is currently not doing reliably.

please and thank you.
