Free CRM comes in two categories – free, but limited (also known as freemium), and open source.
So the free, but limited, versions set caps on the amount of free users, contacts, storage, extra features, or some combination thereof.
Open source, on the other hand, offers an unlimited, fully functional CRM to users. The caveat is that your company needs a person (or team) who can install and configure the CRM. Of course, because of this, open source CRM is extremely customizable, which is nice. Most open source CRM companies also offer a preconfigured version and/or installation and support for a price.
