What Is a Work-in-Progress (WIP)?
Let me explain what work-in-progress, or WIP, really means in production and supply-chain management. It's those partially finished goods that are still waiting to be completed. You see, WIP includes the raw materials, labor, and overhead costs for products at different stages of production. On the balance sheet, it's part of the inventory asset account, and these costs eventually move to the finished goods account and then to the cost of sales.
WIP is one piece of a company's balance sheet puzzle. It only reflects the value of products in intermediate stages, so it doesn't include raw materials that haven't been used yet or finished products sitting in inventory for future sales.
Key Takeaways
- Work-in-progress (WIP) refers to partially finished goods that are not yet ready for sale, with costs including raw materials, labor, and overhead.
- WIP is a crucial part of a company's inventory on the balance sheet, representing an asset until these products are completed and sold.
- Different accounting methods can affect how WIP is calculated and reported, making it important for investors to understand a company's process for assessing its inventory stages.
- The terms 'work-in-progress' and 'work-in-process' can be used interchangeably, though they may refer to different stages of completion depending on context.
Delving into the Dynamics of WIP
Let's dive deeper into how WIP works. It tracks the flow of manufacturing costs through the production process, capturing expenses for goods that aren't done yet. These costs cover raw materials, the labor involved in making the goods, and allocated overhead.
Take manufacturing combs as an example. Plastic starts as raw material, then labor operates the molding equipment. Since the combs aren't fully done, all those costs go into WIP. Once completed, they shift from WIP to finished goods, still under inventory. When sold, costs move to cost of goods sold (COGS).
An item enters WIP when labor is applied but it's not finished. Not all necessary work is done yet. Remember, WIP and other inventory can vary by accounting methods across companies, so as an investor, you need to check how a company measures it. Overhead might be based on labor or machine hours, for instance. WIP is an asset on the balance sheet, and companies usually minimize it before reporting because estimating completion percentage is tough and time-consuming. This approach saves on storage and lowers obsolescence risks.
Crucial Insights and Accounting Practices for WIP
Accountants have ways to figure out partially completed units in WIP, often by calculating the percentage of total raw material, labor, and overhead costs incurred. Raw materials come first since they're needed before labor kicks in.
Process costing differs from job costing. Job costing is for unique customer jobs, tracking specific costs like materials, labor, and overhead for each, which helps with taxes and cost analysis. For example, a roofing company bids on jobs with varying sizes, listing labor, materials, and overhead per roof.
Process costing, on the other hand, accumulates costs for homogeneous products. Think of making plastic combs: plastic molds, then paints, then packages, adding costs as they move departments.
Distinguishing Between Work-in-Progress and Work-in-Process
Work-in-process means partially completed goods, also called goods-in-process. Some use it for products that go from raw to finished quickly, like manufactured items.
Work-in-progress might refer to longer projects, like consulting or construction. But honestly, the terms are often interchangeable for unfinished products. This inventory appears on the balance sheet and can include direct labor, materials, and overhead.
Comparing Work-in-Progress With Finished Goods
The key difference between WIP and finished goods is the stage of completion, basically how sellable it is. WIP is the middle stage where raw materials are being turned into the final product. Finished goods are ready for customers.
These terms depend on a company's inventory accounting and aren't absolute. What one company calls finished goods might be raw material for another. For instance, sheet plywood is finished for a lumber mill but raw for a cabinet maker. So, it's all about the stage relative to the total inventory—WIP is intermediary, finished goods are the end.
Frequently Asked Questions
What does work-in-progress mean in accounting? In supply-chain management, WIP is partially completed goods, or in-process inventory, covering overhead to raw materials at a production stage. It's a current asset and type of inventory.
Is work-in-progress a form of inventory? Yes, when raw material meets labor, it's WIP. It becomes finished product when done, then COGS when sold.
How is work-in-progress calculated? It's often the percentage of total overhead, labor, and material costs. A construction firm might bill at 25% or 50% completion stages.
The Bottom Line
On a balance sheet, work-in-progress captures labor, raw materials, and overhead for unfinished goods still in production, not ready for sale. They're current assets, and companies limit reporting them because estimating completion is hard. Work-in-progress can swap with work-in-process, but the former often means longer projects like construction, while the latter is for quicker manufacturing.
