What is Zero Inventory? (Examples, Tips, Models, Pros, Cons)

Zero inventory (or “zero stock”) is a production and purchasing model in which a company produces or buys only what it needs when it needs it.

This differs from traditional inventory systems, in which a company stocks up on products in anticipation of future sales.

In this post, we’ll take a closer look at Zero Inventory systems, including how they work and their pros and cons. We’ll also offer some tips for businesses considering switching to Zero Inventory.

Zero Inventory

Definition

Zero inventory is a process set up in a business where the firm maintains a meager amount of inventory or no inventory to reduce the possession and storage costs.

That also facilitates the business to enjoy more liquidity which will help expand.

What is Zero Inventory?

Zero inventory is a business model that eliminates carrying any inventory.
This can be achieved through various methods, including just-in-time production and delivery, consignment selling, and drop shipping.

What are the four types of inventory?

The four types of inventory are
1. raw materials
2. work-in-process(WIP)
3. finished items
4. overhaul(MRO – maintenance, repair, operating supplies).

Zero inventory advantages

Reduced Costs

By eliminating the need to carry inventory, you reduce your costs significantly.

Increased Efficiency

Having products delivered just in time reduces the amount of wasted time and energy.

Improved Customer Service

It allows you to provide a faster and more efficient customer service experience.

More Time for Growth

It gives you more time to focus on growing your business.

Greater Flexibility

With it, you have the flexibility to change your product lines quickly and easily.

Few disadvantages to be taken care of

Zero inventory has its own set of potential risks. For example, in an unexpected production plan, the firm might not get immediate stock which upsets the whole supply chain management.

The prices quoted by the suppliers in the short term are generally high, which might add extra costs to the company.

If there are long-term orders, the smooth process of the supply chain ensures that the overall cost of production is borne by the customer, which might not be the case in this scenario.

This system is also beneficial to huge companies with a standard set of vendors whom they deal with. Still, small businesses might not profit from this as their vendors might change, and their production plan is not interpreted and is entirely unexpected.

How to achieve zero inventory

A proper supply chain management system is necessary to achieve zero inventory. The company should have an appropriate track of raw materials, stocks, and product demand.
