Rushabh here from the ERPNext core team. ERPNext is mostly used by small businesses with 3-50 users and covers most use cases for accounting, inventory, sales, purchase and other functions. We estimate there are between 800-1000 businesses using ERPNext at the moment. These are mostly small businesses (non tech) in services, manufacturing, distribution and retail.<p>The project is reasonably stable, but still takes a bit to set it up. The community is quite active (<a href="https:&#x2F;&#x2F;discuss.erpnext.com" rel="nofollow">https:&#x2F;&#x2F;discuss.erpnext.com</a>) and there is a long list of things that need to be done (<a href="https:&#x2F;&#x2F;github.com&#x2F;frappe&#x2F;erpnext&#x2F;issues" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;frappe&#x2F;erpnext&#x2F;issues</a>)<p>It has a metadata based framework and has REST API&#x27;s out of the box. Its never been discussed on HN, so would love to get feedback.
