Common problems and solutions
Why should I use a rollup property instead of just looking at the contacts?
Because the count you already have lives at the contact level — one number per person. A rollup property rolls those individual numbers up to the company level, so you can see total registrations across everyone at an account in a single field. That's what lets you ask "which companies are most engaged?" instead of checking people one by one.
What if a contact is associated with more than one company?
The rollup gathers from associated contacts, so a contact tied to two companies can have their registration count feed into both totals, which can inflate the numbers in a way you didn't intend. HubSpot does give you a couple of levers here: you can restrict a rollup to specific association labels so it only counts the relationship you care about, and the conditions can narrow it further.
When I create it, does it count registrations that already happened?
Yes. A rollup is a calculated property; it derives its value from whatever associated records exist, so existing contacts and their counts get summed in from the start. Nobody needs to register again to "wake it up". One thing to note: these properties update during data changes, not instantly on creation, so on a large account give the initial calculation a little time to populate before assuming a blank total is wrong.
