The big one for us is security and compliance and ease of reporting.
From the compliance perspective we can do audits. For data protection and GDPR this varies between daily reporting to every three weeks in some instances. This reporting is critical to ensure that the work process is in check, and remains compliant. Companies have to get familiar with this (compliance) language. Most CRMs do not focus on compliance, they have some features for it, but it can be done much better.
Businesses focusing on compliance from the start, are much more likely to succeed.
