Dear Dolibarr Community, I am currently exploring the development of a multi-company module for Dolibarr and would greatly appreciate your insights and expertise on the matter. Could you please share your thoughts on the following: 1. What are the essential features or functionalities that a multi-company module should include? 2. Are there any specific challenges or pitfalls I should be aware of when designing such a module? 3. Are there existing examples, best practices, or resources within the Dolibarr ecosystem that I can reference? Additionally, if anyone has experience with multi-company setups or has worked on similar modules, I would love to hear about your experiences and any recommendations you might have. Thank you in advance for your time and support. I look forward to engaging in a fruitful discussion and contributing to the Dolibarr community. ---

We developed this for an earlier version of Dolibarr, it will need some updating but I would be happy to sell you a copy of the code. This wasnt a small project a few months of development went into this. ---

I want to avoid paying monthly/yearly fees for software and need a solution that works specifically for my local envernment. Reinventing the wheel makes sense because existing tools are either too expensive or don’t meet our needs. I want full control, local hosting, and no ongoing costs. If there’s no affordable, self-hosted alternative, building a custom solution might be the best option THANKS @sonikf ---

What do you gain from Multi Company setup that you wouldn’t get from running the setup in containers? ---

Don’t get me wrong but your previous post was how to make a module…furthermore open source does not mean free, what you can avoid in cost you will have to pay with hard work. multi-company might be the most difficult module to maintain because it will have to work with all core modules. Take a look in [Github](https://github.com/Dolibarr/dolibarr) to see how much work existing module dev has done over the years…
