Since 2017, we've seen the same set of mistakes in companies of every size and industry. Each one gets expensive later.
Mistake 1. One person makes the call. Usually the owner or the Head of Sales. They pick a system that suits them, everyone else gets a tool that doesn't solve their problems, and the sabotage begins.
Mistake 2. IT joins at the end. After the decision. Then it turns out the system won't integrate with the phone system and the API is limited. You either reverse the choice or pay for a custom integration.
Mistake 3. Focusing on license price instead of total cost. Teams pick the cheapest plan and then pay extra for everything: integrations, storage, AI add-ons, training, priority support. The "cheap" system ends up costing more than the competitor.
Mistake 4. Testing on the vendor's demo data. Nobody checks how the system handles your real database, your processes, and your integrations.
Mistake 5. Ignoring end users. Only managers attend the demo, and reps hear about the new system on launch day. The result: resistance, empty fields on records, and a failed rollout.
Mistake 6. A selection team with no deadline. Evaluation drags on for six months, people lose interest, and the final decision comes down to "just pick something." Set a deadline on day one.
