Scope changes cost faster than aesthetics alone
The biggest cost driver is usually scope, not whether the website “looks nice”. A site with complex page architecture, strategic copy structure, forms, CRM integration, booking flow, or multiple audience pathways will cost more because it solves more business problems.
This is why fixed package comparisons can be misleading. Two websites may both have five pages, but the depth of strategy, UX, design, and technical implementation behind those pages can be completely different.
