Open-source

There are a number of reasons to using open source CRM software, including no (or reduced) licence costs, the ability to modify the code, and the support of a vivid community. However, these benefits come with trade-offs. Open source CRMs can require significant technical expertise for customisation and maintenance, which can lead to higher long-term costs for those without in-house expertise. Security can also be an issue, as the responsibility for updates and patches rests with the user, which, if left unchecked, can lead to vulnerabilities.
