Hi, some clarifications to your questions.
1) Openbravo Business Suite: this is our former Openbravo ERP solution. An horizontal ERP, CRM and BI functionality for across industries. Read more information here: http://www.openbravo.com/other-industries/
2) Openbravo Commerce Suite: this is a verticalization of the Openbravo Business Suite for the Retail industry, so it includes all available functionality in the Openbravo Business Suite plus specific retail functionality, such as the Openbravo Web POS. Retail is today our focus, so the whole website is focused there.
Both are distributed under two different commercial editions:
1) Enterprise Edition, which allows On Premise or Cloud deployment
2) Professional Edition, only on premise
For the Commerce Suite for example, you can read about our two editions here: http://www.openbravo.com/retailers/edit ... d-pricing/
In regards to our wiki, it is a mistake. When it says "Openbravo 3 Professional Edition", it should say "for Enterprise or Professional Editions", meaning the two I've mentioned before. Will talk internally to fix it.
Hope it helps,
