In a nutshell, it is the complete list of all the items that are required to build a product. A BOM is sometimes also referred to as a product structure, assembly component list or production recipe (in industries). Take, for example, a bicycle manufacturer that wants to build 1,000 bicycles. A bill of materials for a bicycle will include all the parts that make up the bicycle such as seats, frames, brakes, handlebars, wheels, tires, chains, pedals and cranksets, including the quantities required of each component and their cost.
A well-defined BOM helps companies:. Plan purchases of raw materials.
Estimate material costs. Gain inventory control. Track and.
Maintain accurate records. Ensure supply robustness and reduce waste BOM structure Typically, a BOM is hierarchical in nature, with the finished product at the top. It includes product codes, part descriptions, quantities, costs and additional specifications. Among the most common methods of representing a BOM are the following:. Single-level bill of materials, which is a relatively simple list for a product. In this type, each assembly or subassembly is shown only once, with the corresponding quantity required of each to make the product. Though easy to develop, this type of BOM is unsuitable for complex products because it does not specify the relationship between parent and child parts or between assemblies and subassemblies.
If the product fails, a single-level BOM makes it difficult to determine which part needs to be replaced or repaired. Multilevel bill of materials, which takes more work to create but offers greater details and specificity on the parent and child parts in the product. In a multilevel BOM, the total material required is shown. Additionally, the product structure is indented to show the relationship between the parent and child product, as well as assemblies and subassemblies. A BOM serves as the foundation of production planning systems, and the information in it provides the basic data for other business processes, such as manufacturing resource planning, product costing, material provision for production and plant maintenance. Since the BOM combines all possible information that goes into building a final product, it finds wide use in departments beyond manufacturing, such as engineering, design, sales, material management and plant management.
Types of bills of materials There are three main types of BOMs to be aware of: Manufacturing bill of materials. A manufacturing BOM (MBOM) includes a structured list of all the items or subassemblies required to make a manufactured, shippable finished product. An MBOM, in addition to the information on individual parts, also includes information on the parts that require processing prior to assembly and explains how various components relate to one another in a product. The information in the MBOM is then shared with all the integrated business systems involved in ordering and building the product, including enterprise resource planning , material requirements planning (MRP) and, in some cases, a manufacturing execution system.
Engineering bill of materials. An engineering BOM defines assemblies or parts as designed by the engineering department. Showing the component structure from a functional perspective, an EBOM, for example, will consist of a mechanical or technical drawing of a product. An EBOM is typically developed by engineers using computer-aided design or electronic design automation (EDA) tools, and it is common to have more than one EBOM for a product as the design undergoes a series of revisions. Sales bill of materials.
A sales BOM (SBOM) defines a product in the sales stage, meaning details of the product prior to assembly. In an SBOM, the list of finished products and the components required to develop it appear separately in the sales order document. Here, the finished product is managed as a sales item instead of an inventory item. It's important to note that each type of BOM will involve a different structure and level of detail. For example, an EBOM may list parts related to a specific function of the product, such as chips for a circuit board. An MBOM, by definition, lists every material that goes into manufacturing a product.
Creating a BOM in SAP offers well-known functionality to create various BOMs. Legacy users have been able to use BOMs created through SAP R/3 and, and continues that functionality.
Inventory Management Software Quick Summary Inventory management software enables businesses with large volumes of physical products to keep track of those products through various stages along the supply chain. Features include product categorization, sales and purchase order tracking, electronic scanning and automatic ordering. Retailers can typically use scaled-down systems focused on maintaining perpetual inventory, whereas businesses with complex supply chains often use the inventory management functionality in. Benefits of Inventory Management Software While inventory can be tracked in Excel, spreadsheets only work for periodic inventory systems (i.e., inventory systems that are updated at intervals, say after stock takes). Inventory management software is necessary to enable a true perpetual inventory system, where inventory is updated continuously as sales are made and goods are received. Pricing Guide How Inventory Management Software Is Priced Typically, inventory management software is priced according to a number of factors. There are different pricing tiers for businesses of varying size, based on:.
Number of users. Number of locations. Number of SKUs/products. Number of orders processed per month. Number of devices (client PCs, barcode scanners etc.) In addition, whether the software is hosted online or on-premise can make a difference in up-front versus recurring costs. What Businesses Typically Budget for Inventory Management Software We looked at a sample of buyer interactions to compare how much businesses are willing to budget either for monthly fees for cloud platforms or upfront, one-time fees for on-premise platforms.
We've broken this data down by business size in terms of number of licensed users, since licensed users is one of the primary factors affecting pricing for inventory management systems: Typical Inventory Management Software Budget. Hidden Costs of Inventory Management Software.
Hardware. Many businesses will need barcode scanners and printers, and retailers may also need. Accounting integrations. Some vendors price their solutions based on how many accounting systems the inventory management platform integrates with.
End-to-end lot/serial number tracking. Businesses that need full traceability throughout the supply chain will need a full-blown ERP system, which is much pricier than scaled-down inventory management platforms.
FAQs What Are the Key Functions of Inventory Management Software?. Perpetual inventory. With inventory management software, inventory is updated in real time as you receive purchase orders and process sales orders.

Elimination of manual processes. By using barcode scanners in conjunction with an inventory management system, you can speed up tedious processes such as stock takes/inventory counts. Synchronized inventory. E-commerce retailers selling across multiple platforms/channels, retailers with multiple stores and distributors with multiple warehouses all need to synchronize inventory. This can't be done with spreadsheets, since inventory needs to be updated in real time, and requires an inventory management system. What Questions Should I Ask Vendors When Evaluating Inventory Management Systems?. Do you integrate with my accounting software?
Inventory management vendors typically support a range of accounting integrations out of the box, but they might not integrate with your particular system, or they might charge extra for the integration. If you're using QuickBooks, you should evaluate the many vendors that specialize in QuickBooks integrations. How many active clients do you have in my particular industry vertical? Different industries track different things (e.g., color, size, expiration date, style, serial number). Many inventory management vendors specialize in industries such as apparel or pharmaceuticals.
Vendors without experience in these verticals may claim to be able to handle an implementation in your industry, but implementation costs may be prohibitive and the functionality limited. Be sure your vendor has experience with businesses in your industry. What level of support do you offer for warehouse processes? While many inventory management vendors claim to offer warehouse management functionality, typically it's basic, e.g., generating paper pick lists and tracking by warehouse location.
If you need advanced features such as voice-directed picking or slotting, you may need to look into specialized warehouse management systems. Do you sell POS systems? What other hardware will I need? Retailers in particular should evaluate inventory management vendors that also sell POS systems. Distributors will typically need barcode scanners, label printers and other hardware to go along with the inventory management system. What Are Some Drawbacks I Should Watch Out For? There are no real drawbacks to using inventory management software, but there are drawbacks to choosing the wrong vendor for your business.
Only ERP systems offer lot traceability. Lot traceability requires the using a lot number as an item attribute for inventory tracking in all of the supply chain/inventory management/accounting software a business uses. Realistically, businesses should consider an integrated ERP system for lot tracking. Crucial functionality for certain industries is missing from many platforms. Businesses that price inventory by weight (e.g., meat vendors, produce distributors) need to weigh inventory at crucial points in the supply chain for costing and inventory tracking.
This is known as 'catchweight management,' and it's only found in specialized products. Additionally, advanced expiration date tracking and costing will require specialized products. Inventory management offers varying levels of support for supply chain functions. Inventory management solutions are frequently scaled-down in comparison to ERP systems. They may lack some support altogether for supply chain functions, such as procurement or route optimization (for businesses with their own fleets). Logistics providers or 3PLs should be particularly careful when choosing a platform, since they specialize in areas of the supply chain where some inventory management vendors lack functionality. Tips & Tools Build a Business Case for Inventory Management Software Here are three major ROI drivers for inventory management software:.
