Job costing identifies the profits and losses earned for mainly manufacturing jobs. Hence, it becomes convenient to identify the contribution of all individual jobs and their profit for the company.

There are two types of contracts in contract costing namely cost-plus contract and fixed-price contract.

Conclusion

Costing is a necessary tool when it comes to businesses. However, the costing methods differ for each business. The overall purpose of all costing methods is similar that is, to calculate the expenditure, measuring profits and losses, etc., to avoid any future complications, and to have a smooth-running system.

Job costing and contract costing also serve the same purpose in the end. However, each of them is meant to be used by different organizations. When it comes to temporary use for a small-scale job, job costing is the method we use. On the other hand, if the work is a major project that includes a large amount of investment and employees, contract costing is the method commonly used. In contract costing, the total expenditure can change depending on the situation including the condition of the project after a period, the market rates, etc. This is not the case in job costing. The total amount is paid upfront as there are little to no complications.

These costing methods play a significant role in the overall growth of the job or project. With the technology at its all-time-best, accounting software is used by various organizations as it is convenient and accurate since there are no risks of incorrect calculations.
