Buyer's Guide
1What is a CRM and do you need one
A CRM manages your customer relationships and active deals. If you have more than 10 active deals or more than one person involved in sales, a CRM is essential. Without one, leads fall through cracks, follow-ups get missed, and there is no visibility into pipeline health.
2The 5 key evaluation criteria
First, check contacts and deal limits on the entry tier. Second, assess built-in email and calling versus third-party integrations. Third, evaluate custom fields for your specific data needs. Fourth, check automation depth since manual CRMs get abandoned. Fifth, test the mobile app if your team works in the field.
3Questions to ask every vendor
How long does implementation take for a team our size? What does data migration from our current system involve? What is included in onboarding support? What is the cancellation notice period? Are there usage limits that trigger price increases?
4Common mistakes to avoid
Choosing based on features you will never use. Over-customising before the team adopts it. Not mandating full team adoption since a CRM only works when everyone uses it. Choosing cheapest and paying twice when it fails to scale.
