Bulk Purchasing vs. Just-in-Time Supply – Pros and Cons for PPE Procurement

Supplying PPE to your workforce can be complex. You need to keep your team safe at all times, while managing budgets and time pressures.

PPE procurement requires a practical, cost-effective approach. 

That’s where bulk purchasing and just-in-time ordering come in. 

These are two common PPE procurement methods. Each has advantages and limitations, so the right approach depends on your operation.

Both have their advantages and disadvantages, and you’ll need to carefully weigh up these pros and cons. 

Here’s SMI's guide to bulk purchasing vs. just-in-time supply to help you decide what suits your business best.

What is Bulk Purchasing?

Bulk purchasing is exactly as it sounds: when you buy more PPE than you need to stock up for later.

THE PROS AND CONS OF BULK PURCHASING

 

PROS:

1. PPE when you need it - holding greater stock levels means you're less likely to run out of frequently used PPE.
   
   
2. Discounted pricing - Bulk orders often come with reduced unit costs, helping businesses save money on PPE procurement.
   
   
3. Time saving - Buying ahead reduces the number of orders you need to place and means you’re not waiting for inventory to arrive.
   
   
4. Sustainability - Fewer orders mean fewer shipments, which can help lower a business’s logistics footprint and reduce carbon emissions.

CONS:

1. Inventory waste - Storing large quantities of PPE increases the risk that some stock will go unused and ultimately be wasted.
   
   
2. PPE can expire before it’s used - Once PPE has expired, it no longer offers suitable protection. Even unused items continue to age, so holding high volumes of stock can lead to products going out of date before they are needed.
   
   
3. Common causes of PPE inventory waste include:

• Defective or recalled items
• Storage errors or workplace accidents can damage stock
• Changing PPE requirements that don't meet existing inventory

What is Just-in-Time ordering?

Just-in-time (JIT) procurement is the opposite of bulk purchasing. You only buy what you need for when you need it.

THE PROS AND CONS OF JUST-IN-TIME

 

PROS:

1. Space saving - JIT procurement reduces the need for storage space because you only hold the stock you immediately need.
   
   
2. Less chance of over-stocking - Without holding large volumes of PPE, there’s far less chance of over‑ordering and wasting money on unused items.
   
   
3. Sustainability - With fewer items sitting in storage and potentially expiring, JIT reduces waste and can offer a more environmentally friendly approach.

CONS:

1. Procurement needs can be hard to predict - PPE can break or wear out at any time. Because these issues are unpredictable, JIT procurement may not always cover sudden or urgent requirements.
   
   
2. Could be more time-consuming - If you run out of PPE, work can be delayed while waiting for new stock to arrive. Additionally, more frequent ordering cycles mean teams spend more time managing and replenishing inventory.

Bulk Purchasing vs. Just-in-Time: a comparison table

METHOD	COST	TIME	SPACE	WASTE	SUSTAINABILITY
Bulk Purchasing	Potentially cost-saving with order discounts and fewer expensive rush orders.	Saves time by bulk ordering, and you won’t have to wait for shipments.	Requires medium to large storage.	Items are stocked up even when they’re not needed, causing potentially high waste.	Fewer emissions from shipment and delivery.
Just-In-Time	Potentially more expensive due to frequent, low-volume orders.	Takes more time to order and could cause delays when waiting for delivery.	Requires small to medium storage.	Items are replaced when they’ve been used, meaning low waste.	Fewer emissions from waste and disposal.

How to find the right procurement strategy for you

There’s no ‘one size fits all’ when it comes to the right procurement strategy. Every business will have its own unique stock and ordering needs. 

The right strategy depends on factors like:

• The PPE you’re using
• How often you’re replacing your PPE
• How expensive it is to buy and maintain

When you consider these factors, you’ll probably find that neither bulk purchasing or just-in-time ordering are suitable alone.

That’s why a lot of companies find a mix of the two procurement strategies to be most efficient.

The benefits of using Bulk Purchasing and Just-in-Time in your procurement strategy

THE BEST OF BOTH WORLDS

You can bulk-buy frequently needed PPE items, like disposable gloves and safety shoes, on a regular cycle.

This gives you the flexibility to purchase more expensive or specialist equipment on a just-in-time basis, without risk through over-stocking.

BETTER BUDGET TRACKING

Using a mix of fixed (bulk) and variable (JIT) expenses gives you a clearer picture of your procurement spend.

This helps you analyse what is being spent and when, and provides a more accurate view of remaining budget.

EASIER TO REVIEW

With both bulk purchasing and JIT in place, you avoid the pressure of constant urgent ordering.

This makes it easier to assess how well your procurement strategy is working and identify where improvements can be made.

FAQs

Is it best to bulk purchase PPE?

Not always! Bulk purchasing is a common procurement method for PPE because it allows businesses to stay stocked. 

However, this stock can often be wasted before it’s even been used. 

The best procurement strategy will depend on your PPE needs and budget. 

What PPE does my team need?

Most businesses will need to provide the following PPE to their employees:

• Head protection
• Hearing protection
• Eye & face protection
• Respiratory protection

You may also need to provide PPE items like these:

• Fall protection
• Hi-vis clothing
• Safety footwear
• Hand protection

Should I have more than one supplier?

It can be helpful to have more than one PPE supplier. For example, when your main supplier doesn’t have something in stock, you can turn to another supplier.
