Historical Evolution of Cost Accounting

Pre-Industrial Era (Before Late 18th Century)

• Craft production processes dominated.
• Business owners were merchants and bankers, who managed raw materials, craft products, and their sale in markets.
• Economic activity was represented by Financial Accounting, which documented transactions between the company and the outside world, reflecting the company's assets and generated income.
• Assets were reflected on the balance sheet, and income in the Profit and Loss account.

Emergence of Cost Accounting (Late 18th Century)

• This stage began with the Industrial Revolution in England in the late 18th century.
• Companies invested capital, acquired machinery, established their own workshops, and hired a stable workforce.
• Financial Accounting provided information, but not about the cost of their products.
• Consequently, cost information began to appear to inform employers about product costs and how they were generated.

Scientific Production Management (Last Quarter of 19th Century)

• In the last quarter of the 19th century, companies sought to understand the performance and productivity of their workers.
• A large number of new techniques for measuring costs were developed, allowing for the assessment of worker productivity and the correlation of products with benefits; standard costs emerged.
• Employers focused their attention on predetermined standard rates of material and labor consumption, for which time and motion studies were performed.
• Standards provided information to plan workflows, minimizing material loss and downtime, thus becoming a key element in controlling costs.

Emergence of Modern Management Accounting (Circa 1900)

• Around 1900, companies integrated activities previously undertaken by individual firms, such as production, purchasing, transportation, and distribution (vertical integration).
• The complexity of these organizations necessitated the development of more sophisticated cost reporting procedures than those used by single-product companies.
• Companies began to develop modern management accounting, including budgeting and investment analysis.

The "True Cost" Stage (Circa 1925)

• By 1925, companies had developed all the procedures for Cost and Management Accounting.
• However, in the second decade of the 20th century, a significant change occurred: Cost Accounting transitioned from generating information for decision-making to primarily generating information for inventory valuation.
• Additionally, capital providers and tax authorities began to require companies to provide external financial reporting in accordance with certain principles.
• The stock market crash of 1929 was instrumental in the development of inventory-focused Cost Accounting.
• From that moment, Cost Accounting took on a secondary role in businesses compared to Financial Accounting.
