If you need a lightweight CRM (customer relationship management) software, make sure to check out Magna CRM from Rapid Signal. Dimitris, the founder of Rapid Signal, just recently released the Beta of Magna CRM. I tested it and it’s looking great. I tested some other CRMs in the past and most of them were just overkill for us, slow and bloated so I’m happy to see a simple web based CRM for small businesses. A nice feature for software businesses is that you can actually track the licenses of a customer via the Assets feature. It would be great to have an API for it to automatically sync the CRM with a shop/customer portal.
