Maintenance, repair and operations (MRO) refers to the procurement and management of goods and services that are essential for the ongoing maintenance, repair, and daily operations of a business or organization.  MRO items are typically non-production goods and services that are not directly incorporated into the end products or services offered by a company. Instead, they support the overall functioning of the organization. The items that each company stores for this purpose are known as MRO inventory. Examples of MRO inventory items include maintenance tools and equipment, spare parts, lubricants, cleaning supplies, safety equipment, office supplies, and various services such as equipment repairs and facility maintenance.
