I have been searching extensively for weeks and I am at a loss. We are building a big new webshop with Drupal 7 + Ubercart 3 and we are in desperate need of some software to take care of CRM, accounting/finances and preferably also customer support and ticketing. Ideally one integrated ERP (Enterprise Ressource Planning) package that does it all
But it's not easy!
All of these functions are of course vital for most businesses, but we can't come up with a good solution for Drupal.
"ERP" is dead, it seems: http://drupal.org/project/erp/
"Drupal ERP" was an idea, but just an idea it seems: http://drupal.org/project/derp
Then there is "OpenERP", but it does not seem to integrate well with Drupal (even though there is a proxy API), it's interface is clunky and we have written 3 emails to them without receiving any replies. It could be a bit of a headache trying to get this to work.
There is much promise in the new "ERPAL" http://drupal.org/project/erpal, but after some research (reading a bit of German) we have determined that the earliest possible beta release would be in December 2012 - probably later.
So we sort of gave up on finding an ERP, and started looking for smaller software packages that handle isolated tasks. One for accounting, one for CRM etc.
