In the era of digital transformation, ERP (Enterprise Resource Planning) is no longer an exclusive "playground" for multi-national corporations. Small and medium-sized enterprises (SMEs) in Vietnam are increasingly recognizing ERP as the "backbone" for process optimization and competitive advantage.

However, the reality of implementation is far from rosy. According to various reports from Gartner and technology research organizations, the failure rate of ERP projects—or those that fail to meet initial expectations—can range from 50% to 75%. For an SME with limited financial and human resources, a failed ERP project not only wastes the budget but can also paralyze business operations.

Below are the 5 most common mistakes when implementing ERP for SMEs and strategies to ensure your business stays on the right track.

1. Viewing ERP as a purely information technology (IT) project

This is the most systemic mistake. Many SME leaders assume that implementing an ERP is simply about purchasing software, installing it on computers, and handing it over to the IT department to manage.

Why does this lead to failure? ERP impacts every corner of the business: from accounting and sales to logistics and human resources. If viewed only from a technical perspective, the system will lack a connection to actual business processes. When employees across departments feel the software is more of a burden than a support, they tend to reject it or use it only as a formality.

How to fix it:

  • Leadership Commitment: The Board of Directors must be directly involved and view this as a strategy to change the operating model, not just an equipment purchase.
  • Establish a Cross-functional Project Team: The implementation team should include key personnel from all departments to ensure the software addresses their specific "pain points."


2. Choosing overpowered or misaligned software

Businesses are often easily attracted by global ERP "giants" with thousands of complex features. However, for an SME with flexible processes that are still being refined, an overly massive system can become a "straitjacket" or prove to be far too cumbersome.

The issues:

  • Financial waste: Extremely high licensing and maintenance costs.
  • Operational over-complication: Employees spend too much time entering data into unnecessary fields, which reduces overall work efficiency.

How to fix it:

  • Analyze actual needs: Instead of choosing the "best software in the world," choose the software that best fits your scale and specific industry characteristics.
  • Prioritize scalability: Choose platforms with modular architecture (such as Odoo or other flexible customized solutions). This allows you to implement core features first and expand as your business grows.

3. Failing to standardize and clean data before implementation

ERP systems operate on the principle of: "Garbage In, Garbage Out." Many SMEs rush to migrate old data from Excel or disjointed software into a new ERP without verifying accuracy and consistency.

The consequences: When inventory data is incorrect, customer codes are duplicated, or accounting entries don't match, ERP reports become meaningless. The business loses trust in the system within the very first months of use.

How to fix it:

  • Standardize Processes First: Don't automate a broken process. Optimize your business workflows on paper before digitizing them into the software.
  • Data "Deep Cleaning": Dedicate time to review and eliminate "junk" data. Harmonize your master data (product codes, customer IDs, warehouse codes) before importing them into the new system.


4. Lack of training and change management strategy

Implementing an ERP is about changing human work habits. People naturally tend to resist change, especially when they have to abandon familiar tools like Excel to transition to a more strictly controlled system.

Common mistake: Businesses often provide only superficial training during the final days of the project. Employees fail to understand the core logic, leading to operational errors, system bugs, and psychological frustration.

How to fix it:

  • Continuous training: Organize workshops and develop detailed Standard Operating Procedures (SOPs) tailored to each specific role.
  • Internal communication: Help employees understand how the ERP makes their jobs easier (e.g., reducing manual tasks, automated reporting) rather than focusing solely on management oversight.


5. Choosing the wrong implementation partner

Software accounts for only 30% of success; the remaining 70% depends on the partner's implementation capability. Many SMEs choose a provider based solely on the lowest price, overlooking crucial factors like experience and business process expertise.

Risks: An inexperienced partner will struggle to consult on the optimal solution for your company's specific challenges. This often leads to excessive customization that compromises the system's architecture or causes significant project delays.

How to fix it:

  • Evaluate proven track record: Look for partners with a strong portfolio of similar projects within your specific industry.
  • Post-Implementation support: ERP is not a project that ends once you "hit the start button." You need a long-term partner to accompany you for system maintenance and future upgrades.
