Compute total per-diem for crew or talent across multiple cities and days. GSA-aligned default rates; override per-city.
Per-diem is the daily allowance a traveler (crew, talent, or contractors) draws for meals and incidentals away from home base. The US General Services Administration (GSA) publishes city-by-city rates for federal travel; most production budgets use them as a defensible baseline. International rates come from the State Department's DSSR tables.
Per-diem usually settles on a per-show or weekly cadence, cash or paystub. Tour managers track it against the city × day rate matrix so projected never drifts from actual.
Per-diem auto-calculates on every show in Atlas, tied to your roster.
