Enterprise resource planning (ERP) and manufacturing execution systems (MES) are at the forefront of the sophisticated software solutions manufacturers rely on to manage their operations. 

ERP systems act as an organization’s skeletal structure, uniting various business activities such as finances, inventory management, procurement, and human resources management. 

On the other hand, manufacturing execution systems (MES) are concentrated solely on the production stage. It follows and monitors the manufacturing process in real-time, ensuring the best possible usage of available resources, reducing downtime as much as possible, and increasing total productivity.

How To Integrate your ERP & MES

1. Batch Integration

The term “batch integration” refers to the practice of aggregating and processing data collected over a period of time. A manufacturing firm, for instance, would keep track of production data throughout the day, then upload it to an enterprise resource planning (ERP) database at the conclusion of the shift.


  • Saves time and energy by processing data in large batches.
  • Eases the load on ultra-fast computers.


  • Avoid using for tasks that must react instantly to real-time information.
  • There could be data loss if the system crashes before the batch is processed.

2. Real-time Integration

In real-time integration, systems are constantly talking to one another and taking instantaneous action based on the data they receive. As soon as a purchase is made, for instance, a store’s inventory can be updated anywhere it is available.


  • Allows for prompt choice making in light of current data.
  • Perfect for organizations whose operations mirror that description.


  • Heavy on resources, this one needs a solid digital backbone.
  • Difficult to put into action, especially on a broad scale.

3. Middleware Integration

Integrating middleware means utilizing software such as iPaaS to link together otherwise incompatible infrastructures. Using middleware, an online retailer can coordinate the flow of information among its many systems, including its storefront, inventory management, and customer relationship management (CRM).


  • Reduces the complexity of integration by mediating between various programs.
  • Facilitates the linking of disparate corporate systems and data sources.


  • There will be more time and money invested because finding the right middleware software is key.
  • Middleware upgrades and support are dependent on third-party providers.

  • Capable of growing with a company and adjusting to its evolving needs.
  • Saves money and time on building and maintaining infrastructure.


  • Problems could arise in locations with spotty or no internet service due to the reliance on the internet.
  • There are issues with trusting the cloud due to regulatory compliance and data security fears.

5. Custom API Integration

To enable inter-system communication, developers often create unique Application Programming Interfaces (APIs). A manufacturing organization, for instance, may create APIs to integrate its enterprise resource planning (ERP) software with specialist production monitoring software.


  • Adapted to meet individual needs of a company, allowing for easy implementation.
  • It gives you complete command over your data and how it’s used.


  • It needs a lot of work and skill to develop.
  • Difficulties in upkeep occur when APIs require alterations or upgrades.

6. Point-to-Point Integration

With point-to-point integration, two distinct computer networks are linked right away. For instance, an online store’s payment gateway can be connected straight to the enterprise resource planning system.


  • Ease of configuration and installation for targeted integration.
  • Rapid sharing of information amongst the various systems.


  • Problems with scalability arise when integrating new systems because this adds yet another interaction.
  • Long-term upkeep is challenging, especially when there are several connectors involved.
