Content and page depth
A small site with prepared, approved content requires different work from a site that needs research, copy development and many distinct service pages.
Functions and integrations
Bookings, ecommerce, membership, customer portals and third-party systems add planning, testing and maintenance responsibilities.
Support after launch
Hosting, security, updates, content changes and ongoing improvement may sit inside a managed service or be handled separately. Compare the full responsibility, not only the build figure.
