Work-in-Progress (WIP)

Partially finished goods still in the production process, not yet raw materials and not yet finished goods

Definition

Work-in-Progress (WIP) refers to goods that are partially completed in the manufacturing process — they are no longer raw materials but have not yet become finished goods ready for sale. WIP inventory sits between raw materials and finished goods in the production cycle. It includes the cost of raw materials consumed so far, labour applied, and manufacturing overheads incurred up to the current stage of production. For Indian small manufacturers, tracking WIP is essential for accurate inventory valuation, production planning, and cost accounting. Under Indian Accounting Standards (Ind AS 2) and GST regulations, WIP must be valued at the cost incurred up to the current stage of completion. Businesses in sectors like textiles, furniture, engineering components, and food processing often carry significant WIP inventory. High WIP levels can indicate production bottlenecks, inefficient processes, or capacity constraints. Monitoring WIP helps manufacturers identify delays in production, optimise workflows, and reduce the time goods spend on the shop floor. Proper WIP tracking also ensures accurate GST filing because the value of WIP affects your closing stock figures, which in turn impact your profit and loss calculations and tax liability.

How It Works

  1. 1Raw materials are issued from the store to the production floor, and their cost is transferred from raw material inventory to WIP inventory as production begins.
  2. 2As labour and manufacturing overheads (power, rent, machine depreciation) are applied to the partially completed goods, these costs are accumulated in the WIP account.
  3. 3The production team tracks the stage of completion for each batch — for example, cutting done, assembly pending, painting pending — to estimate the percentage of completion and WIP value.
  4. 4Once production is fully completed and quality checks are passed, the goods are transferred from WIP to finished goods inventory at the total accumulated production cost.

Example

A furniture manufacturer in Jodhpur receives an order for 50 wooden dining tables. He purchases timber worth Rs. 2,50,000 and begins production. After one week, 30 tables have been cut and shaped but not yet polished or assembled. The raw material cost consumed for these 30 tables is Rs. 1,50,000, labour charges incurred so far are Rs. 45,000, and power and overhead costs are Rs. 15,000. The WIP value for these 30 partially finished tables = Rs. 1,50,000 + Rs. 45,000 + Rs. 15,000 = Rs. 2,10,000. This amount appears as WIP inventory on the balance sheet until the tables are fully assembled, polished, and transferred to finished goods stock.

How Stock Register Handles This

  • Track manufacturing entries with stage-wise progress so you always know the value of goods currently in production
  • Monitor WIP levels across multiple production batches to identify bottlenecks and delays in the manufacturing process
  • Accurately value closing stock by separately accounting for raw materials, WIP, and finished goods in your inventory reports
  • Generate production cost reports that break down WIP into raw material, labour, and overhead components for each batch

Frequently Asked Questions

How is WIP different from raw materials and finished goods?

Raw materials are inputs that have not yet entered the production process. WIP consists of items that are partially processed — some work has been done but they are not yet ready for sale. Finished goods have completed all production stages and are ready to be sold to customers. All three are classified as inventory on the balance sheet.

Why is it important to value WIP accurately?

Accurate WIP valuation directly affects your closing stock figure, which impacts gross profit and tax liability. If WIP is undervalued, your profits will appear lower and you may underpay taxes. If overvalued, profits appear inflated. Indian tax authorities and auditors scrutinise WIP valuations during assessments, especially for manufacturers.

How can I reduce WIP in my manufacturing business?

Reduce WIP by improving production efficiency, eliminating bottlenecks, reducing batch sizes, and streamlining workflows. Implement lean manufacturing principles, ensure raw materials are available on time, and schedule production runs to minimise idle time between stages. Lower WIP means faster production cycles and less capital tied up in inventory.
