Not necessarily from scratch. The customer data, product information, and historical orders accumulated in your ERP or legacy systems are already valuable assets. When adopting a new tool, prioritize evaluating whether you can import or integrate this existing data to avoid duplication and rework. Rework not only wastes labor but also often triggers employee resistance, stalling digitalization efforts from the start. In practice, you can test the complete workflow with a batch of well-organized data first, verify field mapping and data quality, then proceed with full import—rather than waiting until everything is perfectly prepared, which rarely happens.
