Routing Mileage expenses to payroll

Summary:

In e-bus we had a solution to route car mileage expense payments via payroll rather than accounts payable.

Some of the reasons behind this were to pay home to base mileage which is taxable at source, and also to provide information for P11D documentation at year end.

Fusion out the box adopt functionality is to route mileage and expenses via AP.

I would be interested to hear from other HR/Payroll users who now pay mileage expenses via AP and what obstacles they have had to overcome and what the solutions they use to overcome these.

Thanks
