What is Cost Accounting?
The practice of capturing, classifying, and analysing the costs of producing goods or delivering services.
Definition
Cost accounting determines what it actually costs a business to make a product or deliver a service by tracking direct materials, direct labour, and overhead, and assigning them to products, jobs, projects, or services. Unlike financial accounting, which reports to outside parties, cost accounting is primarily for internal decisions on pricing, product mix, make-versus-buy, and process improvement. It uses methods such as job costing, process costing, standard costing, and activity-based costing depending on how production is organised. Accurate cost data is essential for understanding margins and controlling spending.
How Cost Accounting Works in ERP
An ERP captures cost data automatically from inventory movements, production orders, timesheets, and purchasing, then assigns and absorbs overhead using configured cost rules. It can value inventory and cost of goods sold using methods like standard, average, FIFO, or actual costing, and surface variances for analysis. Manufacturing-focused ERPs link cost accounting to the bill of materials and routings so product costs roll up automatically.

Frequently Asked Questions
How is cost accounting different from financial accounting?
Financial accounting produces statements for external stakeholders like investors, lenders, and regulators, following standards such as GAAP or IFRS. Cost accounting is internal, focused on understanding and controlling the costs of products and operations to support management decisions. It does not have to follow external reporting standards and can be tailored to the business. ERPs feed both from the same transactional data, so cost insights and financial reports stay consistent.
Which costing method should a manufacturer choose in an ERP?
The right method depends on the production model: job costing suits custom, project-based work, process costing suits continuous or repetitive production, and standard costing suits stable, high-volume manufacturing where variances are monitored. Many ERPs let you configure the method per item or facility. The choice affects inventory valuation, margin reporting, and how variances are analysed. It is an important configuration decision during implementation.
