The three panels of a record
Every record in HubSpot (contact, company, deal, ticket) has three panels:
Left sidebar. The "About this [object]" section. This shows the most important properties for the record. It's the quick-reference view, the first thing a user sees when they open any record. This is where your customisation effort pays off the most.
Middle column. The activity timeline. Shows emails, calls, meetings, notes, tasks, and any other interactions. A detail worth knowing: activities on associated records show up here too. If someone sends an email from the company record, that email also appears on the linked contact's timeline. You can filter by activity type (emails only, calls only) and by which associated records to include.
Right sidebar. Shows associations (linked companies, deals, tickets) and attachments. Also displays any custom cards you've added.
All three panels are customisable, but the left sidebar is where you get the most return on effort.
Customising the "About this" section
The default "About this contact" section shows every property HubSpot thinks is important. For most teams, half of those are irrelevant. The fix takes two minutes:
Open any contact record. Click the settings icon (the gear) on the left sidebar. This opens the record customisation panel. From here you can add, remove, and reorder properties. You can also create entirely new sections with their own groupings.
One important distinction: if you customise through the gear icon on a record, the change applies to your entire team (or to specific teams you select). If you customise through the "Actions > Customise properties" dropdown, the change applies only to your personal view. For most implementations, you want the team-wide version so everyone starts with the same baseline.
Creating custom sections
Beyond editing the default section, you can add new sections to the left sidebar. This is where things get useful for teams with specific workflows:
A "Qualification" section with properties like ICP match, buyer role, and BANT criteria. An "Onboarding" section with properties like onboarding stage, assigned CSM, and kickoff date. A "Contract" section with properties like contract value, renewal date, and payment terms.
Each section acts as a logical grouping. When a sales rep opens a contact, they see the "Qualification" section with just the three fields they need to update after a discovery call. They don't have to scroll past twenty irrelevant fields to find them. That reduction in friction is what turns a CRM from something people tolerate into something they use.
