Portuguese Mileage & Per Diem

Log business trips in Portugal and calculate the mileage (subsídio de transporte em automóvel próprio) and per diems (ajudas de custo) within the tax-free ceilings of the Código do IRS, artigo 2.º n.os 3 d) and 14.

Someone logs the trip and the tax-free allowance is worked out at the official rates for Portugal, then lands in the ledger already coded. No claim spreadsheet, and no rate table for a finance person to remember to update when the authorities move them.
