Vendor Master for Interviewees and expenses payment process in SAP

Hello All,

We are trying to figure out a process for people who come for Interviews and submit their expenses and get a cheque from our company. How can this be carried out in SAP..Please add your valuable inputs to the process below:

Create Vendor master in SAP..( Which account group? Dodnt want to use primary account group. One time vendor account group does not have address fields maintained... )

When the interviee submits his expenses..( Do we create a PO to pay ? Do we just create a Invoice MIRO ? Do FB60)

Kindly Advice,

Thanks
