What is MRO Inventory?

MRO Inventory, or Maintenance, Repair and Operations Inventory, is a type of inventory that includes all the items a company needs to maintain its facilities and equipment. This can include everything from replacement parts to janitorial supplies. While MRO Inventory is not typically used to produce products or services, it is necessary for keeping operations running smoothly.

A company’s MRO Inventory can be divided into two main categories:

-Direct materials: These are the materials that are used in the production process and become a part of the finished product. For example, if a company manufactures automobiles, the direct materials would include the metal and plastic parts that go into making each car.

-indirect Materials: Indirect materials are not directly used in the production process but are necessary for the operation of the business. For example, office supplies like paper and pens would be considered indirect materials.

What are the benefits of MRO Inventory?

MRO inventory can offer many benefits to businesses, including cost savings, improved efficiency, and reduced downtime.

1. Cost Savings: MRO inventory can help businesses save money by reducing the need for expensive emergency repairs and replacements.

2. Improved Efficiency: By stocking MRO inventory, businesses can avoid production delays and disruptions caused by equipment failures.

3. Reduced Downtime: Having MRO inventory on hand can help businesses recover quickly from unexpected equipment failures, minimizing lost production time.

How to get started with MRO Inventory

There are a few key things you need to know in order to get started with MRO inventory:

1. MRO inventory is classified as any material that is used to support the maintenance and operations of a company, but is not part of the finished product. This can include items such as tools, spare parts, and equipment.

2. It is important to have a good understanding of what your company’s specific needs are in order to create an effective MRO inventory strategy. This includes knowing which items are absolutely essential and which can be ordered on an as-needed basis.

3. There are a variety of methods that can be used to track and manage MRO inventory, so it’s important to find the system that works best for your business. Some companies use software programs specifically designed for this purpose, while others simply utilize Excel spreadsheet templates.

4. Creating accurate and up-to-date records of your MRO inventory is critical for effective management. This includes keeping track of both physical items and repair/replacement parts.

5. Regular auditing of your MRO inventory levels is necessary in order to ensure that you have the correct amount of materials on hand at all times. This will help avoid both stock outs and excessive carrying costs.


MRO inventory is an important part of a business’s operations. It helps to keep track of the maintenance and repairs that need to be done, as well as keeping current inventory levels in check so that customer service can be maintained. MRO inventory also helps businesses reduce costs associated with ordering new parts and supplies, since many items already in stock can often be used for repair and maintenance purposes instead. Being knowledgeable about MRO inventory will help any business ensure efficient operations and better customer service.
