New Hampshire hosts a dynamic mix of business travel. Managing the costs associated with this travel requires a clear, consistent, and legally compliant per diem policy.
This guide provides a detailed breakdown of the official GSA per diem rates for New Hampshire, explains the state's important laws regarding employee expenses, and shows how you can use automation to manage the process with ease.
