Construction project
In this video you will see a construction company specializing in business offices. Creating a cost estimate to bid, but billing based on actual hours worked and materials input. Usually starting with a contract that sets the price of materials and the rate for workers, subcontractors, etc. Once the client agrees to the parameters of the project, it is on to scheduling and then actually performing the planned work. Each month the project manager invoices the clients based on materials and time worked.
