The invoice is typically used to charge by the hour, indicating the hourly rate for each mover, the number of hours worked, and the resulting cost. It is wise to clearly define the rate charged for each service provided as they vary, be it assembling or disassembling furniture, packing, moving specialty items, each should be indicated on the invoice with the rate and total cost. Any discounts can be accounted for before calculating the total fee and providing the client with the invoice and due date.
