HubSpot's own migration service charges a $500 setup fee plus $20 per page for content migration, making a 50-page site roughly $1,500 through HubSpot directly. Agency-led migrations with strategic redesign, conversion optimization, and CRM setup range from $5,000 for small sites to $25,000 or more for enterprise-level projects with complex requirements.
The price variation comes down to scope. HubSpot's in-house migration recreates your existing content in their CMS but does not include graphic design, custom development, or content strategy. You get your pages moved, not improved. Agency migrations typically bundle content audit, messaging strategy, template design, conversion path planning, CRM configuration, and post-launch support. Most mid-sized B2B websites with 50 to 200 pages land in the $10,000 to $15,000 range when working with a specialized agency. Factors that push costs higher include custom integrations with third-party tools, complex CRM data migration from platforms like Salesforce, multilingual content, and the number of unique page templates needed. Lean Labs offers programs starting at $2,000 per month that bundle migration with ongoing growth optimization, which spreads the investment across a longer engagement rather than requiring a single large upfront payment.
