How To Manage And Optimize Spare Parts Inventory

July 5, 2022

From manufacturing equipment to fleet maintenance, having spare parts at your disposal is critical to keeping your most essential equipment functional at all times. The problem? Businesses with disorganized spare parts systems can end up with fewer components than they need at a given time. 


This shortage can complicate matters should you not have the components you need to keep your business operational. Fortunately, all that’s required to avoid this issue entirely is to better manage and optimize your spare parts inventory. This guide will dive into a few helpful tips to make spare parts management seamless. 


Label Your Parts and Develop a Process for Removal

Arguably two of the most significant issues that those dealing with spare parts inventory management face are not properly labeling parts and not creating a system to track their removal. 


By labeling, we don’t mean that you need to inform your employees about what these items are (although this is helpful). Instead, you need a labeling system that results in efficient inventory management. Two great systems include the ABC system (highest, intermediate, and lowest consumption value, respectively) and the XYZ system (little variation and reliable forecast, some variation, most variation, respectively). 


Of course, properly labeling does little if employees do not have a system they can follow when removing and tracking parts.  So, create a standard work order process and train employees so that they know to file a formal work order and how the system functions. This training will eliminate any issues you’re currently facing on this front. 


Understand Your Buying Cycles and How Much Inventory You Have

Spare parts are necessary, but the last thing you want to do is order too much (or little) or cut deep into your profits to keep these items on hand. 


To better address the first part, you can use sawtooth diagrams and create a visualization of when you replenish your spare parts inventory and how quickly it dwindles over time. Then, with further insight into your purchasing habits and how often you go through spare parts, you can better prepare for the future. 


To ensure you’re not spending too much on inventory, you can use a formula for support. The economic order quantity is designed to help you minimize inventory holding and related costs. You can calculate the economic order quantity using the following formula: EOQ = square root of 2(setup costs)(demand rate) / (holding costs).


Conduct Regular Cycle Counts and Occasional Total Inventory Counts

Managing your spare parts inventory involves more than just labeling products and developing systems around them. Checking in to see what you have on hand and ensuring that your new systems are functioning as expected is also crucial to the process. 


Total inventory counts may be conducted from time to time. However, cycle counts can be useful as they’re not disruptive. These types of counts are audits of a group of inventory parts to ensure that the amount of items in your inventory matches what you have in your system. You may even develop a regular schedule for these types of checks!

How Smart Product Selection Protects Reliability & Equipment Performance
January 14, 2026
The start of a new year is more than a calendar reset, it’s an opportunity to strengthen the systems that keep your business running efficiently. For industrial, commercial, and maintenance-driven operations, having the right supplies in place at the right time can mean the difference between staying productive or falling behind. Building a smarter supply strategy early in the year helps businesses control costs, reduce downtime, and remain competitive in an increasingly unpredictable supply environment. Here’s how to evaluate your needs, forecast usage, and put reliable systems in place for the year ahead. Why Strategic Supply Planning Matters Reactive purchasing often leads to higher costs, rushed decisions, and inconsistent inventory levels. Without a clear supply plan, businesses risk overordering, stockouts, and delays that impact operations and customer commitments. Strategic supply planning allows organizations to: Improve operational efficiency Reduce emergency purchases and downtime Stabilize pricing through better forecasting Build stronger supplier relationships When supply strategy is aligned with operational goals, purchasing becomes a competitive advantage, not just a necessity. Step 1: Evaluate Your Current Supply Usage The foundation of any effective supply strategy is understanding what you actually use. Reviewing historical purchasing data provides valuable insight into patterns, seasonality, and inefficiencies. Key questions to ask: Which products are used consistently throughout the year? Where do usage spikes or slowdowns occur? Which items frequently require rush orders or last-minute replenishment? Identifying high-use and critical items helps prioritize where planning and standardization will have the greatest impact. Step 2: Forecast Demand with Operational Input Accurate forecasting requires collaboration across departments. Operations, maintenance, and procurement teams all play a role in anticipating demand. Consider factors such as: Planned maintenance schedules Production volume expectations Seasonal workload fluctuations Equipment upgrades or expansions By incorporating operational insight into forecasting, businesses can better align inventory levels with real-world needs, reducing both excess stock and shortages. Step 3: Standardize Products and Vendors Standardization simplifies purchasing, improves consistency, and often reduces costs. Evaluating opportunities to standardize frequently used supplies—such as safety products, fasteners, tools, or consumables—can streamline procurement and inventory management. Working with a trusted supplier also provides access to product expertise, availability insights, and alternative solutions when supply challenges arise. Step 4: Set Systems in Place Early Establishing purchasing systems early in the year creates stability throughout the months ahead. This may include setting reorder points, implementing blanket orders, or coordinating scheduled deliveries for high-use items. Proactive systems reduce the need for emergency purchases and allow teams to focus on operations rather than constant supply management. Step 5: Build a Supply Partner, Not Just a Vendor A strong supply strategy goes beyond transactions. Partnering with a knowledgeable supplier adds value through product recommendations, inventory support, and responsiveness when challenges arise. The right supply partner understands your business, anticipates needs, and helps you adapt as conditions change throughout the year.

FAQs Why is supply planning important at the start of the year? Early planning helps businesses forecast demand, stabilize costs, and reduce disruptions caused by shortages or emergency purchases. How can businesses improve inventory efficiency? Evaluating usage data, forecasting demand, standardizing products, and working with a reliable supplier are key steps toward more efficient inventory management. What should a supply strategy include? A strong supply strategy includes usage evaluation, demand forecasting, product standardization, purchasing systems, and a trusted supply partner.
