1. Data Migration Issues: Migrating data from legacy systems can be challenging due to format incompatibility, data quality issues, poor mapping tables or data loss risks. Proper validation and sample data sets for testing migrations are crucial to avoid complications.

2. Change Management: ERP implementation brings change, and users may resist new workflows or systems. Address this with tailored training, consistent communication, and early involvement to build confidence and comfort. Try to have a ‘what is in it for me’ lens so you can be prepared to handle any objections.
3. Scope Creep: During implementation, it can be tempting to add new features or customizations, which can lead to scope creep. To avoid this, stick closely to the initial project scope and prioritize essential functionalities. It is okay to pin features for a future phase.
4. Underestimating Resources: ERP projects require time, money, and human resources. Underestimating any of these can lead to delays. Having a well-defined project plan, sufficient budget, and a dedicated team can mitigate this risk.
5. System Integration Issues: If you have multiple systems, ensuring they integrate smoothly with your new ERP can be complex. Working with experienced ERP consultants and integrating system technical teams can help address challenges.
