Mileage rows capture sanctioned routes (round-trip or multi-stop totals), SAR-per-kilometre bands per grade/project, exclusions that mirror internal travel policies, lowering spreadsheet rework downstream.
Optional waypoint or map attachments corroborate long trips when auditors want evidence beyond spreadsheets.
Monthly or per-batch caps autop enforce entitlement ceilings configured in Preferences so finance does not babysit calculators each payroll cycle.
