How long should I plan for a HubSpot website build or migration?

A HubSpot website build or CMS migration often needs about 10 to 16 weeks when the scope includes strategy, design, theme and module setup, content migration, forms, tracking, testing, and launch planning. A smaller implementation can move faster when content and decisions are ready, while custom modules, CRM cleanup, workflows, integrations, redirect mapping, or a large migration can extend the schedule. Treat the range as an early planning estimate, not a fixed promise. Your project timeline should name what is included, who approves each phase, and what must be ready before development starts.
