10 Best MES Software According to Operators

Teams are spending up to 30% of their workweek on manual, time-consuming documentation, according to a National Association of Manufacturers (NAM) report. 

That’s exactly the kind of operational drag manufacturing execution systems (MES) are designed to eliminate. They bring structure to work that has become too complex and too fast-moving for manual processes to keep up. 

And manufacturers are already moving in that direction. A recent Deloitte survey shows that advanced production scheduling (35%) and execution systems (33%) are now the highest-priority investments for the next two years. This data reflects a clear shift toward replacing manual activity with integrated, real-time digital control.

A well-implemented MES reduces that manual burden, improves accuracy, and gives leaders the real-time visibility they’ve historically lacked. But because every production environment operates differently, the “best” system isn’t one with the most features; it’s the one flexible enough to adapt to your processes.

We assessed the best MES systems based on user feedback from G2, Gartner, Reddit, and other industry forums. And below, we've rounded them up to help monitor, control, and optimize production processes. Let's dive in.

Factors To Consider When Choosing MES Software

When comparing MES options, consider how well each system fits your factory's current operations and your expansion plans. The right choice depends more on how the MES features support your workflows, teams, and growth plans.

Business needs

Start by clarifying what problems you actually need to solve—whether it's visibility, traceability, scheduling, or quality. The MES you pick should directly support those priorities without forcing unnecessary complexity.

Scalability

Choose a MES software that can handle your future scaling needs, not just your current production units. If you expect to add more lines, plants, or products, make sure the system can grow without needing a full rebuild.

Integrations

MES delivers value only when it connects well with ERP, PLM, machines, and quality systems. Look for MES systems that offer easy connectors so you don’t spend months building custom integrations.

Mobile access

If operators and supervisors move around the floor, mobile access can make a big difference. Simple tablet or phone interfaces help teams respond to issues quickly.

Security and compliance

Verify that the MES system meets your industry’s requirements, especially if you’re in a regulated industry. Check for built-in audit trails, user controls, and data protection to save trouble later.

User-friendliness

Even the best MES software customized to your industry specs is ineffective with a poor user interface. So pick manufacturing execution systems with clean screens, clear workflows, and a minimal learning curve so operators and engineers can adopt them quickly.

Vendor support

Choosing and setting up the best MES software is a complex process, and it requires regular maintenance and vendor support. So make sure to choose vendors who offer quick responses, good documentation, and a helpful user community.

Monitoring and analytics

Real-time dashboards and simple reporting tools help you spot problems before they grow. Look for manufacturing software systems with easy-to-design dashboards and user interfaces that can be customized to your KPIs.

Total Cost of Ownership (TCO)

The total cost of the MES isn’t just the licensing cost. Consider the cost of implementation, upgrades, integrations, and internal resources, and make sure it aligns with your budget and the value you expect.

FAQ

What is MES software used for?

Companies use MES software to manage, track, and control manufacturing operations in real time. It connects people, machines, materials, and workflows so companies always know what’s happening on the shop floor. 

In practice, MES helps teams reduce errors, improve quality, meet compliance requirements, and maintain full traceability from raw materials to finished goods.

How do you implement an MES system?

Most manufacturers implement an MES in phases: starting with one process or line, connecting it to existing systems, validating the workflows, and training operators. Once that foundation is stable, teams expand to additional lines or sites.

Is MES the same as ERP?

No, MES and ERP solve different problems. ERP handles business planning, including purchasing, inventory management, finance, and order management. MES handles production execution, including work instructions, quality checks, machine data, genealogy, and real-time performance tracking. 

When manufacturers integrate MES and ERP systems, they get a complete view from order creation to product delivery.
