Contract Costing 159

Introduction

Contract Costing is a specialized form of job costing used primarily in the construction industry and for large-scale projects that extend over a long period. It is suitable for businesses engaged in the execution of contracts such as building construction, civil engineering works, shipbuilding, and road construction. In contract costing, each contract is treated as a separate cost unit, and costs are accumulated for each contract individually. The main objective is to ascertain the cost and profit associated with each contract. This method helps in controlling costs, determining profitability, and facilitating the preparation of financial statements.
