Short answer
The cost and timeline of a business website depend mainly on the number of pages and templates, the level of custom design, who writes the content, the features and integrations required, and the support needed after launch. Clear decisions on these early keep projects predictable.
Why do website quotes vary so much?
Two quotes for a website can differ widely because they often describe very different projects under the same name. One may be a template with your logo added and placeholder text, while another includes research, custom design, professionally written copy, search optimisation, integrations and training. Before comparing quotes, compare what is actually included: the number of page designs, content responsibility, features, testing, hosting, security and support. The scope explains most of the difference.
How do pages, templates and design affect the effort?
Effort depends less on the total number of pages than on the number of distinct page templates. Fifty service pages that share one layout take far less design work than ten pages that each look different. A site built on a ready-made theme is faster to deliver than a custom design created around your brand, though custom design usually explains your offering more clearly. Animation, illustration, photography and video each add time for planning, creation and review.
Who writes the content, and why does it matter?
Content is the most common cause of website delays. If your team is writing it, pages often wait weeks for text and images while design and development are already finished. If the agency writes it, the project includes time for interviews, drafting and review rounds, but the timeline is usually more predictable. Either way, content written to answer customer questions clearly helps search rankings, AI answers and enquiries far more than generic descriptions.
Which features and integrations add the most work?
Simple enquiry forms, maps and social links add little effort. Features that connect to other systems or handle customer data take more time, because each one needs access to the other system, agreed rules for what data moves where and careful testing for failures. That is why integrations deserve their own line in any project plan. These features take noticeably more planning and testing:
- Online booking, payments or a shopping cart
- Customer logins, portals or member areas
- Integration with a CRM, ERP or WhatsApp
- Multiple languages with separate content
- Calculators, configurators or custom search
How does the platform choice affect cost and timeline?
WordPress and similar content management systems are quick to set up and easy for teams to edit, which suits most business websites. Headless or custom-built sites take longer at the start but offer more speed, security and flexibility for complex needs. Website builders are fastest but limit design, performance and ownership. The right choice depends on how often you update content, what features you need, who will maintain the site and how long you plan to keep it.
What ongoing costs should you plan for after launch?
A website needs hosting, a domain, an SSL certificate and often business email, all of which renew regularly. Software, themes and plugins need updates for security, and backups need checking. Most businesses also want small content changes, new pages and campaign landing pages over time. An annual maintenance plan covers these predictably. Budgeting for ongoing care from the start avoids a well-built site slowly becoming slow, outdated or vulnerable.
