ERPNext

Kommentare: Excellent for small businesses with limited resources. Probably good for medium sized businesses as well as there are several mid sized companies (< 10 million t/o) also using this as figured out through the forum. There is a very active forum and a very good team of active developers. Would recommend the product purely on its stable functionality, ease of use and comprehensiveness.

Vorteile: Very very low cost if you can implement and host it yourself. We have hosted it on AWS and for the price of just the AWS infrastructure you have a world class system at your beck and call. We have been using it for the last 2 years and run our small company (20 people) on this system for everything from purchase-to-pay, order-to-cash, accounting, payroll and HR, inventory etc. It is also available as SaaS for a very reasonable price/seat. The system is comprehensive and very thoughtfully designed and actively developed. It addresses country specific requirements for the most part (please check for your country).

Nachteile: The upgrades are a bit difficult for someone who is non technical. New feature requests usually are addressed but needs external funding/support as it is open system and developed by the community. Best way to use it after evaluating if viable for your business (by trying the 30 day trial on the cloud) is probably as SaaS.

Kommentare: Very active community, any feature you need can be requested on github issues and as per the importance and other priorities your issue/feature request will make it to core product eventually. Whole community, core team, service providers and ERPNext Open Source Software Foundation, India are aligned to resolve issues / requests posted on github.

Vorteile: Free and Open Source
Foundation and Community backed ERP
Easy Web UI
Actively developed.

Nachteile: No proprietary dependencies can be put into core product. Not suitable for anti-free software companies. Rolling release, No LTS. Not suitable for organisations that cannot adapt to regularly updated ERP system.
e.g Some organizations still need FoxPro based systems, not suitable for such organizations.
