Regular monitoring of WIP inventory helps detect defects early in the production process, reducing rework, minimizing waste, and ensuring higher-quality finished goods. Consider using inventory management services when your manufacturing business grows enough to need outside help. Specialized providers of inventory and warehouse management, called third-party logistics (3PL), can free up a business to focus on growth in new markets and add customers. Because it’s difficult and time-consuming to calculate, most merchants try to have as much inventory as possible in the finished goods stage before the end of a reporting period.

How to Calculate Work in Process Inventory

• As such, the difference between WIP and finished goods is based on an inventory’s stage of completion relative to its total inventory.
• When tracking your work in process inventory, it’s important to understand the difference between job costing and process costing.
• The total WIP inventory value is the ending work in process inventory for an accounting period—and the beginning work in process inventory for the next accounting period.
• The accounting system accounts for the semi-finished goods in this category.
• Once the company has those metrics, it can calculate the work in process inventory with the formula below.
• The cost of goods manufactured, or COGM, is a crucial KPI for manufacturers that measures the total expenses incurred from manufacturing the finished products completed in this financial period.
• It is helpful for all eCommerce businesses to understand the calculations however, because those raw materials and manufacturing costs are factored into the price you pay for finished goods.

Without accurate data about current stock levels and future demand projections, you won’t be able to decide how much material you need to have on hand. Finally, having accurate data about your WIP inventory lets you plan better when you’re ordering. It means you’ll be able to keep the right amount of product on hand, at any given time, without overstocking items that may not sell quickly. Techniques like value stream mapping can also help you identify areas where WIP accumulates unnecessarily. Value stream mapping visually charts the entire production process, revealing inefficiencies and areas of WIP accumulation.

Manufacturing Overhead

For accounting purposes, process costing differs from job costing, which is a method used when each customer’s job is different. QuickBooks is a complete solution for inventory management, offering everything from one-click processing and mobile scanning to inventory analysis and reporting. It has everything you need to keep your products, customers and transactions synced and secure, freeing you up to focus on your business.

• The regular audits can really help you understand the position of the WIP inventory.
• Understanding the process and movement of WIP inventory is important because it might show how efficiently your supplier or manufacturer generates finished goods.
• Work in process in the production comes in the total cost of the unfinished goods that are currently experiencing the manufacturing process.
• This includes construction materials on-site, partially assembled equipment, or software code still being developed.
• With the right tools, you can streamline your inventory tracking process, reduce errors, and improve overall efficiency.

Hire a 3PL to Manage Your Inventory and Fulfillment Process

WIP manufacturing is tightly constrained by enforcing a rule that a department cannot produce without a kanban signal. Where appropriate, especially in batch manufacturing environments, efforts should be made to reduce machine set-up time, by applying Single Minute Exchange of Dies (SMED) concepts. Looking at a sequence of manufacturing operations, typically one step work in progress inventory has the least capacity.

When you know the things that are present in your inventory, it will help you order everything in the right manner. You will know the things that are excess in the inventory and the things that are in shortage. This means that you reduce the cost of waste and order the raw material accordingly. Overhead costs include rent or mortgage payments, equipment maintenance, employee benefits, insurance, utilities, and depreciation.
