8.1 Accounting information about product, service and project costs
A business revolves around the provision of goods and/or services. To make a profit a business must sell its goods and/or services at a price that covers all of the costs associated with providing those goods and services and plus margin of profit.
Managers use cost information for many decisions including:
- pricing decisions
- product mix decisions
- market segment decisions
- decisions regarding work to be done in-house or externally by a contractor
- new product decisions
- expansion decisions.
Cost information is used to help control costs, to help in the budgeting process, and in valuing inventories.
Job costing can be straight forward, as with a service business that has no inventory and no manufacturing process to convert raw materials into finished goods. The service industry generally has administration costs and wages of the staff providing the service. It is not enough to set prices or make decisions based on the cost of the staff that are actually providing the service to the clients; it is necessary to include some portion of the administration costs in every price. It is necessary to know the full cost of providing each service.
Job costing becomes very complicated in a manufacturing business that uses inventory and has a process that converts raw materials into a finished product. Inventory that is bought at different times may carry different costs. How does the accountant or manager know the cost of the particular items of inventory that were used in a particular finished product in order to calculate its selling price? The calculation of cost of goods sold (COGS) is more complicated for a manufacturer as there are many more components to consider.
The first reading introduces the topic of costing information and is particularly useful for the table that defines different kinds of costs.
