Key takeaways
- Outsource for specialist skills, flexible capacity and non-core work; keep critical assets under in-house control.
- The vendor's price is one cost; add monitoring, engagement, transition, learning curve and downtime.
- Four models exist: full-service fixed bid, labor only, SLA or performance-based, and as a service.
- Keep equipment knowledge and history in your own CMMS so any vendor can use it.
- Judge vendors on response time, cost per maintenance event, backlog and OEE.

Outsource maintenance when you need specialist skills, flexible capacity or cover for non-core work, and keep it in-house when equipment knowledge and response time drive uptime. The true cost is more than the vendor's invoice: it includes monitoring, engagement, transition, learning curve and downtime. Many plants run a hybrid, with a CMMS holding the asset history.
Many organizations struggle with whether to outsource their regular maintenance operations or keep it all in-house. This is an important decision for maintenance managers and higher-ups. While outsourcing maintenance requirements can provide many benefits, it’s important to understand the true costs involved. This guide breaks down the true costs of outsourced maintenance, from monitoring to downtime.

What Are the True Costs of Outsourcing Maintenance?
Outsourcing maintenance can be an effective strategy for businesses looking to save costs and increase efficiency. However, before deciding to outsource, it’s important to understand the true costs involved. The costs below show why each one matters when you evaluate an outsourcing arrangement.
Outsourced Cost
The outsourced cost is the most obvious cost associated with outsourced maintenance. This refers to the cost of the maintenance service provider, which is typically determined by the vendor’s pricing structure. It’s important to note that while outsourcing maintenance may seem like a cost-saving measure, it’s not always the case. In some cases, outsourcing can be more expensive than in-house maintenance. Therefore, it’s important to carefully evaluate the cost of outsourcing versus the cost of maintaining equipment in-house.
Cost of Monitoring
The cost of monitoring refers to the cost of tracking work orders, scheduling maintenance, and overseeing the quality of the work being done. When outsourcing maintenance, it’s important to establish clear communication channels and protocols to ensure that work is being done correctly and on schedule. This requires dedicated resources to monitor and manage the work being done, which can add to the overall cost of outsourcing maintenance.
Cost of Engagement
The cost of engagement refers to the cost of establishing communication channels and protocols with the service provider. This includes the time and resources required to establish a contract, negotiate terms, and ensure that both parties have a clear understanding of their roles and responsibilities. While this cost is often overlooked, it’s important to consider the time and resources required to engage with the service provider and establish a working relationship.
Cost of Transition
The cost of transition refers to the cost of transitioning from in-house maintenance to outsourced maintenance (and/or vice versa). This includes the time and resources required to identify the right service provider, establish a contract, and transition from in-house maintenance to outsourced maintenance. This can be a significant cost, especially for businesses that have relied on in-house maintenance for an extended period.
Cost of Learning Curve
The cost of the learning curve refers to the cost of learning how to work with the service provider and their processes. When outsourcing maintenance, it’s important to ensure that all parties have a clear understanding of the work being done, how it’s being done, and who is responsible for what. This requires time and resources to train employees and establish clear communication channels with the service provider.
Cost of Downtime
The cost of downtime refers to the cost of lost productivity due to equipment downtime. When outsourcing maintenance, it’s important to ensure that the service provider can minimize downtime and maintain equipment in a timely and efficient manner. Downtime can be costly for businesses, especially those that rely on equipment for their day-to-day operations.
Return on Investment in Vendor Resources
The return on investment in vendor resources refers to the potential cost savings and increased efficiency gained by outsourcing maintenance. When evaluating outsourcing arrangements, it’s important to consider the potential return on investment in vendor resources. This includes cost savings from reduced labor costs, increased efficiency from streamlined maintenance processes, and improved equipment reliability.
How Do You Optimize Outsourced Maintenance?
Outsourcing maintenance can be an effective strategy for businesses to save maintenance costs and increase efficiency. However, to truly optimize outsourced maintenance, businesses need to consider several key factors. We’ll take a closer look at how to optimize outsourced maintenance and ensure that businesses are getting the most out of their outsourcing arrangements.
Expertise On-Demand vs. Vendor Markups
When outsourcing maintenance, businesses need to balance the cost savings of expertise on demand with the potential markups charged by the vendor for parts and supplies. It’s important to evaluate the pricing structure of the vendor and determine whether it makes sense to purchase parts and supplies directly, or through the vendor.
Who Owns the Equipment Knowledge?
Efficient maintenance requires knowledge of the plant assets individually and collectively. Knowledge often rests with the vendors. Establishing mechanisms to harvest knowledge is crucial when working with outsourced vendors. This ensures a clear knowledge capital that is readily owned by the in-house team but accessible to all the necessary vendor resources.
Systems and Tools
A computerized maintenance management system (CMMS) can be used in conjunction with various maintenance strategies such as condition monitoring, which involves the use of sensors and data analysis to predict equipment failures and schedule maintenance proactively. By integrating CMMS with condition monitoring, businesses can ensure that maintenance is performed only when necessary, optimizing resource utilization and reducing costs. Additionally, maintenance management software can support condition-based monitoring, which involves assessing equipment performance and wear-and-tear to determine when maintenance is required. A CMMS also gives you one record of every work order, response time and repair, so you can hold vendors to their service levels and keep the asset history in-house.
High Turnover of Resources
High turnover of resources can have a significant impact on the quality of maintenance work being done. It’s important to consider the vendor’s turnover rate, training, and transition plans and how they may affect the quality of the work being done.
Balancing Cost, Quality, and Efficiency
Balancing the costs of outsourced maintenance with the quality and efficiency of the work being done is key to optimizing outsourced maintenance. It’s important to evaluate the vendor’s performance and ensure that they are meeting agreed-upon service levels.
Margin Squeeze vs. Sub-Standard Delivery and Downtime
Cost-cutting measures should not result in sub-standard work or increased downtime. It’s important to ensure that the vendor is delivering quality work and that any cost-cutting measures don’t compromise the quality of the maintenance work being done.
Return on Investment
Evaluating the return on investment of outsourcing maintenance is crucial. This includes evaluating the cost savings, increased efficiency, and improved quality of work resulting from outsourcing maintenance.
Exit Clauses vs. Making it Win-Win
While it’s important to have exit clauses in case of dissatisfaction with the service provider, businesses should strive to create a win-win situation for both parties. This involves establishing realistic expectations, clear deliverables, economic incentives, communication channels, metrics, and commitment.
When Should You Keep Maintenance In-House, Outsource or Use Both?
Keep in-house the work that depends on deep knowledge of your process: critical and safety-related equipment, first-line response and routine PMs. Outsource work that needs rare skills or equipment, such as specialist overhauls, calibration or extra labor for a shutdown. Most plants end up with a hybrid, and a shared CMMS record of work orders, costs and asset history keeps both teams working from the same facts.
How Do You Select an Outsourced Maintenance Provider?
Selecting the right service provider is crucial to the success of outsourced maintenance functions. Some factors to consider include:
- Expertise and experience: The service provider should have the necessary expertise and experience to effectively maintain the equipment.
- Communication and responsiveness: The service provider should have clear communication channels and be responsive to customer needs and concerns.
- Pricing and value: The service provider should offer competitive pricing and provide value for the services provided.
- Flexibility and scalability: The service provider should be flexible and able to scale services as needed.
- Quality assurance: The service provider should have clear quality assurance processes in place to ensure the quality of the work being done.
Which KPIs Measure Outsourced Maintenance?
Measuring key performance indicators (KPIs) is crucial to ensuring the success of outsourced maintenance. Some KPIs to consider include:
- Response time: Measuring the vendor’s response time can provide insights into their ability to provide timely maintenance services.
- Cost per maintenance event: Measuring the cost of each maintenance event can help evaluate the cost-effectiveness of outsourcing maintenance.
- Maintenance backlog: Measuring the backlog of maintenance work can provide insights into the vendor’s efficiency and capacity.
- Overall equipment effectiveness: Measuring overall equipment effectiveness can help evaluate the effectiveness of the maintenance program.
