Datev is a very popular Software in Germany. The Datev ERP system is one module that lots of shopowners have in use.
So one of the most important question for shopowner is: can i connect magento to my ERP system i already have in use for years. In this case Datev. If magento cannot be connected to that - they will not change to magento… And i speak about lots of shopowners!
Here you can find information about Datev ERP system in detail, unfortunately only in german language: http://www.datev.de/portal/ShowPage.do?pid=dpi&nid;=25932&zg;=un
For reference, there are various methods to connect applications together and may want to refer to this information. Given that, we use the hub approach to connect between applications, this is for stability and upgrade independence between applications.
Obviously there are various methods to integrate Datev and Magento, we have adapted the hub method for these smaller integrations as it used by most enterprise companies, providing it as both SaaS online and on-site self-hosted models.
