Most common ERP errors in SME companies

And how to avoid these problems
October 12, 2026 by


Implementing an ERP system is an important step in the digitalization of many SMEs. It promises more overview, more efficient processes, and better decision-making. However, in practice, we see that ERP projects do not always deliver the desired results.

Not because the software is not good, but because mistakes are made during the process itself. Below we discuss the most common pitfalls we encounter in SMEs.


1. Viewing ERP as a software project instead of a change project

One of the biggest mistakes is approaching an ERP implementation as a purely IT project. In reality, it is about a change in how an organization operates.

Processes are organized differently, responsibilities shift, and departments must collaborate differently. When this organizational aspect is underestimated, resistance arises and the system is used inefficiently.


2. Too much customization from the start

Many companies want their ERP system to fully align with existing practices. As a result, a lot of customization is built right away.

Although this sounds logical, it often leads to higher costs, complexity, and limited flexibility in the future. In successful implementations, the focus is first on how processes can be standardized before customization is added.

Modern, modular platforms like Odoo cleverly respond to this: by starting with the rich standard functionality, a company can first transform, and only in a later phase look at where customization truly adds strategic value.


3. Unclear or incomplete process definition

An ERP system is only as good as the processes that are set up within it. Yet, many projects start without these processes being clearly defined.

Without a clear process definition, discussions arise during implementation, delays occur, and ultimately systems that do not optimally align with practice are created.


4. Insufficient attention to data

Data is the foundation of any ERP system. Think of customers, products, suppliers, inventory, and financial data. A common mistake is that data quality only receives attention late in the project. Poor or incomplete data leads to errors in reports, inventory issues, and inefficient processes after going live.


5. Lack of user involvement

ERP systems are often chosen by management but used by employees. When end users are not sufficiently involved in the process, a gap arises between design and practice.

Good implementations involve end users early in the process, so that the system aligns with daily reality and adoption is increased.


6. Insufficient focus on adoption and training

An ERP system is only successful if people work effectively with it. Yet, training is often underestimated or limited to a short session just before going live.

In practice, adoption is an ongoing process. Employees need time, guidance, and repetition to truly make new working methods their own.


7. No clear vision for the future

ERP systems are often chosen for the current situation, while companies continuously change. Without a clear vision for growth, scalability, and future processes, there is a risk that the system will quickly be limited again by new demands and additional solutions.

This is why we at Kilurion specifically work with Odoo. Thanks to the modular setup, you can start small (for example, only with CRM and Finance) and later seamlessly expand to production, HR, or e-commerce when the organization is ready for it.


Conclusion

A successful ERP implementation is not just about technology, but especially about people, processes, and prior choices. By consciously dealing with standardization, data, adoption, and future vision, you increase the chances of a system that not only works today but also grows with the organization.

At Kilurion, we help SMEs avoid these pitfalls. As an experienced Odoo partner, we set up ERP projects from start to finish in such a way that the software follows the processes, and not the other way around. With a focus on simplicity, scalability, and a seamless adoption in the workplace.
