**Summary:** One-time payment covering an entire trip's or period's estimated business expenses.

- A lump-sum reimbursement is a single payment — before or after the trip — covering all estimated business expenses (fuel, lodging, mileage) in one rounded amount.
- Easy for finance, but commonly non-accountable and therefore taxable as wages.
- Useful for short trips where processing per-receipt substantiation costs more than the tax savings.
