How Much Inventory Should a Fire Protection Company Keep on Hand?
Considering Buying in Bulk?
THE WHOLESALE BUYER'S GUIDEInventory can be a tricky balancing act for fire protection companies. Keep too little on hand, and you may face expensive rush shipping, delayed jobs, and frustrated customers. Keep too much, and your cash gets tied up in products that may sit on the shelf for months.
That balance is becoming increasingly important. A 2025 supply-chain planning report found that 55% of small and midsize businesses were carrying at least 20% excess stock, while 46% reported that at least 5% of their inventory was considered dead stock.
So, how do you find the right balance? Here are a few factors to consider when deciding how much inventory your fire protection company should keep on hand.
For many fire protection companies, regularly stocked inventory may include fire extinguishers, brackets, cabinets, service components, fusible links, and other everyday supplies. HedrickPro offers access to more than 12,000 fire protection products from leading manufacturers, giving contractors a single source for frequently used inventory.
1. Start With Your Most Frequently Used Products
The first place to look is at what your company uses the most.
Review your past service calls, installations, and customer orders to identify the products you consistently need. This may include common fire extinguishers, brackets, cabinets, parts, tags, signage, or other frequently used components.
These high-demand products are usually worth keeping readily available because running out could slow down multiple jobs.
A good rule of thumb: If you use it every week, you probably shouldn't have to wait for it every time you need it.

2. Consider Lead Times and Shipping Costs
Not every product needs to take up space in your warehouse.
If a product is readily available from your supplier and can arrive quickly without expensive shipping costs, you may not need to stock a large quantity. On the other hand, products with longer lead times or high emergency shipping costs may be worth keeping in inventory.
Think about the cost of not having the product when you need it.
If ordering something at the last minute means paying premium freight or delaying an important job, keeping a small amount on hand could save your company money in the long run.
Your ordering strategy can also affect shipping costs. HedrickPro currently offers free shipping on qualifying small-parts orders over $500 and free freight on stocked orders over $5,000, with exclusions applying to certain products such as hazardous materials, chemicals, bulky items, and fire extinguishers.

3. Don't Tie Up Cash in Slow-Moving Products
More inventory is not always better.
Specialty products or items that are rarely requested can quickly tie up valuable cash and warehouse space.
The cost of excess inventory goes beyond the purchase price. A commonly cited inventory-management benchmark estimates annual carrying costs at roughly 20%-30% of inventory value once expenses such as storage, insurance, labor, capital, shrinkage, and obsolescence are considered. That means $100,000 in inventory could potentially cost $20,000-$30,000 per year to carry.
Before ordering a large quantity, ask yourself:
- How often do we actually use this?
- How long could it sit on our shelves?
- Can we get it quickly when a customer needs it?
- Is there a risk of the product becoming outdated or damaged?
Your inventory should support your business, not drain your cash flow.
4. Set Minimum Stock Levels
One of the easiest ways to stay ahead of inventory problems is to establish a minimum stock level for your most important products.
For example, if your company typically uses 20 units of a specific extinguisher each month, you might decide that once inventory drops below 10 units, it's time to reorder. This is often called a reorder point: the inventory level that signals it's time to place another order before stock runs out.
The right number will depend on your sales volume, supplier lead times, available storage, and budget. The goal is to create a system that prevents you from discovering you're out of something when you already need it.
Running Low on Common Equipment?

5. Review Your Inventory Regularly
Your inventory needs will change as your business grows.
A product you barely used last year may become one of your most frequently ordered items, while other products may no longer be worth stocking. Review your purchasing and usage patterns regularly to make sure your inventory strategy still makes sense.
Regular reviews can also help prevent excess stock from becoming dead stock. In the 2025 survey, 17% of SMBs reported that more than 10% of their inventory was dead stock, up from 12% the previous year.
Even a simple monthly review can help you spot products that are running low, identify slow-moving inventory, and make smarter purchasing decisions.
6. Build an Inventory Strategy That Supports Growth
The goal isn't to have a warehouse full of products. The goal is to have the right products available at the right time.
A smart inventory strategy can help your team respond faster, avoid unnecessary rush shipping, improve cash flow, and provide better service to your customers. By tracking what you use most, understanding supplier lead times, and setting clear reorder points, you can create an inventory system that supports your business as it grows.
At Hedrick Pro, we help fire protection companies get the products they need with wholesale pricing and the resources to make smarter purchasing decisions.
