Definition
A one-time charge for setup and training, sometimes required to buy a plan.
Onboarding fee explained
HubSpot requires onboarding on Professional ($1,500) and Enterprise ($3,500) plans, on top of seat costs. Enterprise CRMs such as Salesforce and Dynamics often need a paid implementation partner as well.
Ask whether onboarding is required or optional, what it includes and whether it can be waived or credited.
