As the percentage of completion method requires definite receipts but estimated costs so this method is not advisable when receipts of contract are not given. In this scenario there generally appears no contract so it must be the case of a builder who intends to sell the constructed completed project after incurring self costs. In such situations the completion method suits the best.

In case the project has been finalised with fixedcontract price and the contractor has his own estimated costs or else the contractor/ builder has entered into contract with various parties ( the prospective buyers) , in advance( before commencing the project/ billing etc.,), with sure receipts then the percentage of completion method is better to be adopted.
