Most Powerful Open Source ERP

Executive - Is ERP5 for me?

This page will help you to determine if ERP5 is the right solution for you. It will introduce ERP5 along with assessment criteria as well as highlighting key factors that can make an ERP5 implementation a success or failure.

What is ERP5?

ERP5 is an open-source ERP written in Python. It is part of the software stack developed and maintained by Nexedi that also includes Wendelin for Big Data & Machine Learning and SlapOS for cloud deployment and orchestration.

Whereas most ERPs are business field specific ERP5 uses a single model, called Unified Business Model, to describe all of its components. Because of its generic nature ERP5 has over the years been implemented across multiple industries around the world ranging from banking, government, automotive, tolling, trade to manufacturing and aerospace. Solutions are often characterized by a high level of customization, security requirements, need for 3rd party software integration and scalability.

ERP5 can be used for ERP, CRM, CMS, DMS, e-commerce, e-business, finance, data analytics, Web publication, API publication, online office suite, appstore, and more. ERP5 cannot be used as a reporting tool (it can interface with PALO and others) or as a GIS system (it can interface with openstreetmap).

Further Recommended Readings

For more information about ERP systems in general the ERP5 MOOC is a good reference. The origins of the Unified Business Model and the reduction to a the 5 class model are explained in this IEEE research paper. Further readings to consider:

  • Mourlon Neyers Memorieerp - reasons of the failure of ERPs and business appications in general.
  • Un Point De Vue d'Ingenieur Sur la Gestion des Organisations - explains why organisations take irrational decisions, such as selecting an expensive proprietary ERP that a team of 100 people will implement in more than 5 years rather than an Free ERP Software such as ERP5 implemented by a compact team in one year.
  • Myth - explains why organisations may keep on consciously taking decisions that look irrational.
  • Primer on Decision Making - provides a subset of the two previous documents based a behaviourist approach.
  • Théorie général des coûts - explains why the cost of something does not exist (as opposed to the price of something) and thus why ERP5 handles the different types of costs through reporting .
