This guide is designed to be practical, not theoretical. You can use it as a starting point for a CRM clean-up, a health check before a migration, or a way to sense-check whether your current HubSpot setup is giving your team the clarity they need.
Work through the six steps in order, or jump straight to the areas where you already know there are problems. If your team is struggling with unreliable reporting, broken automation, poor segmentation or duplicated records, the scorecard will help you identify what needs attention first.
Clean CRM data is not just about tidying up fields or removing old contacts. It is about giving your team a stronger foundation for the systems, reporting, automation and AI tools they depend on every day.
If your CRM has reached the point where a quick clean-up will not fix it, this guide will help you understand what is happening, what to prioritise and where you may need a more structured approach.
B2B contact data decays at roughly 2.1% a month, close to a quarter of a database going stale in a single year, without anyone making a single data entry error.
Add in wasted ad spend, sales time lost chasing bad records, and reporting nobody trusts, and it stops being a hygiene issue and starts being a commercial one. It also matters more than it used to: every AI feature, automation and reporting layer your team adds only works as well as the data underneath it.
