Page 1 of 1 ## ERPNext Business application An integrated ERP spanning sales, purchasing, stock, accounting and manufacturing. ### Why we recommend it We recommend it when several business areas must share records and processes, including customer portals or service operations. ### When to choose it - Connected ERP, order-to-invoice processes and customer self-service. ### What to consider - The broad scope raises migration and operating effort; check local accounting requirements and upstream compatibility. ### Start with this project Validate one end-to-end business process using real sample data and explicit acceptance criteria.
