The most common mistakes when choosing ERP modules


In today’s business world, enterprise resource planning (ERP) systems have become indispensable tools for the efficient management of operations.

These systems integrate and automate a variety of key processes, from accounting and finance to supply chain and customer relationship management. However, choosing the right ERP modules can be a complex challenge, fraught with common mistakes that can have negative consequences for companies.
The following are some of the most common mistakes made when choosing ERP modules and the repercussions they can have:

Failure to clearly define needs

This fundamental error arises from the lack of a thorough analysis of the company’s specific processes and needs. Without a clear understanding of your company’s objectives, module selection becomes haphazard and ineffective. This results in:

Inadequate functionality

The ERP system does not meet the real needs of the company, which generates frustration among users and limits the return on investment.

Unnecessary modules

Investments are made in modules that do not add real value to the business, which represents an excessive expense and an unnecessary overload of the system.

Excess of modules in your ERP

The false belief that “more is better” can lead to the selection of a large number of modules, without considering the complexity and cost involved.An ERP system overloaded with redundant or underused modules can generate:

  • Difficulty of use: The interface becomes complex and unintuitive, making it difficult for employees to adopt and use the system effectively.
  • Increased costs: Implementation, maintenance and licensing of numerous modules significantly increase the total ERP system expense.
  • Poor performance: An overloaded system can exhibit slowness, failures and errors, affecting productivity and efficiency of operations.

Selection of modules not suitable for industry

Each business sector has its own specific characteristics, challenges and needs. Ignoring this aspect when choosing ERP modules can result in:

Limited functionality

The system does not have the necessary tools and capabilities to address industry-specific problems and processes, which limits its usefulness.

Lack of integration

The modules are not properly integrated with existing systems and processes, creating information silos and hindering a holistic view of the business.

Adaptation costs

Costly customizations and modifications are required to adapt the modules to the needs of the industry, which increases implementation time and cost.


Disregarding your ERP budget

These systems can vary considerably in price, from basic solutions to highly customized options. A realistic budget should be established according to the company’s financial capabilities. On the contrary, we would find:

  • Overinvestment: Excessive resources are allocated to the acquisition of expensive modules that are not essential, limiting investment in other priority areas of the business.
  • Incomplete implementation: Lack of financial resources forces to postpone or eliminate important modules, leaving the ERP system incomplete and not meeting all the needs.
  • Frustration and loss of confidence: Failure to meet budget expectations generates frustration among managers and employees, eroding confidence in the ERP project.

Lack of evidence and evaluation

Acquiring and implementing modules without prior evaluation can be a significant risk. Testing the modules thoroughly will allow us to:

Validate functionality

Ensure that the modules meet expectations in terms of usability, efficiency and ability to meet the needs of our business.

Identify problems

Detect possible bugs, errors or limitations of the modules before full implementation, allowing corrective actions to be taken or alternatives to be sought.

Reducing risks

Minimize the risk of unpleasant surprises and failed investments by having a clear understanding of the actual performance and capabilities of the modules.

Insufficient training for users

No matter how sophisticated it may be, an ERP system cannot reach its full potential if employees are not properly trained to use it. Lack of staff training could be affected in the following ways:

Low adoption

Users may be reluctant to use the system due to lack of knowledge or confidence, limiting its impact on operations.


Incorrect use of the modules could generate errors, incomplete data or delays in the processes, affecting productivity and quality of work.

Frustration and loss of productivity

Difficulty in using the ERP system would generate frustration among employees, which negatively impacts their motivation and productivity.



Choosing the right ERP modules is a strategic decision with a significant impact on the success of the implementation. A well-configured ERP system can optimize processes, improve efficiency, enhance decision making and generate a competitive advantage for the company.

We must avoid the above-mentioned mistakes and follow a series of recommendations in order to boost ERP efficiency, business growth and profitability:

  • Involve end users and managers from different departments in the selection process to ensure that the modules chosen meet the needs of all levels of the organization.
  • Call on expert ERP consultants for personalized advice and take advantage of their expertise in the selection and implementation of modules.
