Drafting a Policy for Conveyance Allowance
You have to draft a policy and state on what basis the amount shall be paid. Generally, for sales professionals, you may fix a monthly amount depending on their ranks and the amount of travel you expect them to do. If it is on an actual basis, you may fix rank-wise travel by Bus+Metro, travel by Auto, and for seniors, travel by Taxi. You have to discuss with management and implement by issuing policy/guidelines/office orders.
Best wishes,
