Trip based automated per diem
SAP Concur offers a trip based automated per diem function. You enter your starting address and date, your travel to address, and your return dates. Based on that information, per diem is automatically populated for the employee using the GSA per diem rates. It is impressive, but doesn't seem that complicated to me. If SAP Concur can do it, then so can Expensify. You can do it Expensify.
