How much does a custom HubSpot implementation project cost?

A custom HubSpot implementation project typically costs between $3,000 and $25,000 or more, depending on the number of hubs, data migration complexity, integration requirements, and level of customization. Straightforward setups with a single hub run $3,000 to $7,000, while multi-hub enterprise projects with complex integrations can exceed $25,000.

Lean Labs publishes tiered pricing on its HubSpot projects page: onboarding starts at $2,000, implementations at $5,000, migrations at $7,000, and integrations at $15,000. These starting points reflect increasing complexity, not fixed packages. The final cost depends on how many hubs need configuration, the state of your existing data, how many third-party systems need to connect, and how much process definition (lifecycle stages, lead scoring, workflow logic) is required before configuration can begin. DIY implementations cost less in agency fees but require significant internal time, typically 6 to 8 weeks for small businesses and 3 to 6 months for enterprises. The hidden cost of going internal is rework: building something that needs to be rebuilt because the original setup did not account for scale, team workflows, or data hygiene.
