Amazing – we have a CRM system similar to OpenCRX; but ours costed tens of thousands dollars, and it’s proprietary.
Of course, most of the time you’ll need to have it customized to your exact needs. In this case, you can get in touch with CRIXP. OpenCRX will be still free, while they provide you with the customization that you need.
Looks really sweet.
And talking about sweet, SugarCRM is another one that looks quite good as well.
