The final account is the last word on what the contract is worth: every variation, provisional sum, remeasure, loss and expense and fluctuation settled. These guides cover building it, agreeing it and the timetable to the final certificate.

Read nowA final account is not an invoice with a bigger number. It is the contract sum, adjusted line by line for everything that changed, each line carrying its own paper. Built as you go it takes an afternoon; reconstructed at the end it takes a month and loses money.
Read nowLoss and expense is reimbursement of actual loss, proved. The recognised heads are narrower than most claims assume.
