Set up for sales only. There's a deal pipeline but no inquiry pipeline. New leads live in the system; existing clients live in a manager's head. The most common mistake of all.
Automation launched without testing the logic. Nobody ran a test pass. A week later, clients are being congratulated on purchases that never happened.
Data collected and never read. The survey runs, reports build, no decisions follow. A metric that changes nothing wastes your manager's time and your client's.
The team doesn't understand why. If people don't see what's in it for them, they fill in the minimum. Skipping the "why" is behind most cases of
CRM being quietly sabotaged.
Too much structure at launch. Twenty required fields and fourteen stages, and the team works around the system by week two. Start minimal, add on request.
Implemented and forgotten. Processes go stale, new channels appear, the team changes shape. Review quarterly, or within a year you'll manage on data that describes nothing.
