The honest range for a B2B SaaS website redesign in 2026 is $15,000 to $500,000+. That range is so wide it's barely useful. The variables that drive it are more informative than the number itself.
The three tiers
Template-first ($15,000-$50,000). A premium Webflow or WordPress theme, customized with the company's brand, populated with real content, and launched in 4-8 weeks. This works well for pre-Series A companies with limited content, a single product, and a primary goal of "looking credible." The limitation is structural — template architectures constrain layout options, and the site will look similar to other companies using the same theme.
Custom design, standard build ($50,000-$150,000). Original UX and visual design, implemented on a standard platform (Webflow, Next.js, or a headless CMS). This is where most Series A-C companies land. The design is tailored to the company's positioning and buyer journey. The build uses established patterns and frameworks. Timeline is 8-14 weeks for a 15-30 page site.
Custom everything ($150,000-$500,000+). Original strategy, original design, custom development, and often custom CMS integration. This is for companies where the website is a core product surface — developer tools with interactive documentation, platforms with self-serve onboarding, or enterprise companies with complex multi-segment architectures. Timeline is 12-24 weeks.
What actually drives the cost
Number of unique page templates. A homepage, an about page, a pricing page, and a contact page is four templates. A company with five product lines, three industry verticals, a resource center, a partner directory, and a careers section might need 15-20 unique templates. Each template requires design, development, content, and QA. This is the single largest cost driver.
Content creation. Most redesign budgets assume content exists. It usually doesn't — at least not in the form the new design requires. Copywriting, case studies, product screenshots, illustrations, and video production can add 30-50% to the base design and development cost.
Integrations. HubSpot forms, Marketo tracking, Segment analytics, Drift chat, Clearbit enrichment, G2 review widgets. Each integration adds complexity to the build and ongoing maintenance burden.
Performance requirements. A standard marketing site with a 2.5s LCP on mobile is achievable with any modern framework. A site that needs sub-1s LCP, perfect Core Web Vitals, and works reliably on 3G connections in emerging markets requires more engineering rigor and more testing.
Where the money actually goes
On a $100K redesign, the approximate allocation:
- Strategy and content planning: 15% ($15K). Positioning, information architecture, content audit, wireframes.
- Visual design: 25% ($25K). Design system, page templates, responsive variants, motion design.
- Development: 35% ($35K). Frontend build, CMS setup, integrations, performance optimization.
- Content creation: 15% ($15K). Copywriting, case studies, imagery.
- QA, launch, and training: 10% ($10K). Cross-browser testing, analytics setup, CMS training.
The hidden costs
Opportunity cost. A 16-week redesign project requires 4-8 hours per week from at least one senior stakeholder. Over four months, that's 64-128 hours of leadership time diverted from product, sales, or fundraising. Research on executive attention allocation suggests this hidden cost is routinely underestimated.
Maintenance. A custom site built on a modern framework requires ongoing maintenance: security updates, dependency updates, content updates, performance monitoring. Budget $1,000-$5,000/month for maintenance on a custom build, or ensure the platform (Webflow, WordPress) handles this automatically.
Migration risk. Redesigns that change URL structures without proper redirects will lose organic search traffic. SEO migration planning should be part of the project scope, not an afterthought.
How to scope it correctly
Start with the page count. List every page the new site needs. Include pages that exist today and pages that need to be created.
Group pages into templates. Most pages share a template. A blog post and a case study are different templates. Two blog posts are the same template.
List every integration. Forms, analytics, chat, CRM, enrichment, A/B testing. Each one adds scope.
Define content ownership. Who writes the copy? Who produces the imagery? Who records the videos? If the answer is "the agency," the cost increases. If the answer is "us," the timeline extends.
Set a performance target. "Fast" is not a specification. "LCP under 2.5s on 4G mobile in the US" is a specification.
Before committing to a full redesign budget, consider whether a targeted conversion rate optimization pass on existing pages might deliver comparable pipeline lift at a fraction of the cost. Companies with enterprise buyers often need a different approach entirely, as the site's job shifts from converting visitors to arming internal champions.
RNO1 has delivered website redesigns across all three tiers for companies including Rezolve AI and Amount. The most predictive factor in project success is not budget — it's whether the company completed the strategy phase before starting design.
Frequently Asked Questions
How long does a B2B SaaS website redesign take?
Template-first projects launch in 4-8 weeks. Custom design on a standard platform takes 8-14 weeks. Fully custom builds with CMS integration run 12-24 weeks. The timeline extends when content creation falls to the client team without dedicated writing resources.
Is it cheaper to redesign on Webflow or build custom?
Webflow reduces development cost by 40-60% compared to a custom-coded site, but introduces constraints on complex interactions, dynamic content, and integrations. For a 15-30 page marketing site without heavy personalization, Webflow is typically the better value. For sites with custom applications, interactive product demos, or complex data integrations, a custom build pays for itself in flexibility.
What's the ROI of a website redesign?
The most common measurable returns are improved pipeline conversion rate, shorter sales cycles, and reduced cost-per-lead from paid campaigns. Companies that redesign with a clear CRO framework typically see 20-40% improvement in visit-to-pipeline conversion within the first quarter post-launch.
Should we redesign the whole site at once or phase it?
Phase it. Launch the homepage and top 5 landing pages first. Measure performance for 30-60 days. Then roll out secondary pages. This reduces risk, provides data for iterating on later pages, and keeps the team focused on the highest-traffic surfaces first.
