In 2026, a B2B SaaS website typically costs $5,000 to $15,000 for a semi-custom marketing site, $15,000 to $50,000 or more for a fully custom one, and $15,000 to $60,000 or more with a specialist SaaS agency. What you actually need depends on your stage: a pre-seed company rarely needs more than one strong landing page, while a company heading for Series A usually needs 15 to 20 pages with a CMS.
At INSAIM, a SaaS landing page starts at $5,000, a brand and launch site at $8,000, and a SaaS marketing website at $8,000, design and build in Webflow or Framer included. We are a Lisbon-based Certified Webflow Partner and Framer Expert Agency, and these are the prices we actually quote.
What you usually need at each stage, and what it costs at INSAIM:
| Stage | What you need | INSAIM, from | Typical timeline |
|---|---|---|---|
| Pre-seed | One landing page to validate demand and collect a waitlist | $5,000 | 3-5 weeks |
| Seed | A brand and a first website | $8,000 (Startup pack) | 4-8 weeks |
| Seed to Series A | A SaaS marketing website, 8 to 20 pages with a CMS | $8,000 (around $15,000 for 20 pages) | 8-12 weeks |
| Any stage, design ready | Build of a corporate website in Webflow or Framer | $5,000 | 3-4 weeks |
| After launch | New pages, campaign pages, ongoing changes | $3,900/month subscription, one-month minimum | Ongoing |
Prices are in USD and exclude VAT and platform fees. INSAIM prices checked against our current price list on 13 October 2026.
B2B SaaS website cost by company stage
Pre-seed: one landing page
Before product-market fit, the site has one job: explain the problem, show the product and collect sign-ups or demo requests. A single, well-structured landing page does this better than ten thin pages. At INSAIM a SaaS landing page starts at $5,000, designed and built in Webflow or Framer, typically in 3 to 5 weeks.
Seed: a brand and a first website
After a first round, early-stage SaaS teams usually need a brand that looks credible to customers and investors, and a site to match. The INSAIM Startup pack covers brand identity, landing page design and the build in Webflow or Framer, from $8,000, typically in 4 to 8 weeks.
Seed to Series A: a SaaS marketing website
Once sales and marketing grow, the site needs product and pricing pages, solutions by role or industry, customer stories, a blog and a CMS the marketing team can run without developers. At INSAIM a SaaS marketing website starts at $8,000, designed and built, typically in 8 to 12 weeks. That starting price fits a compact site; a site of around 20 pages with several CMS collections usually comes closer to $15,000.
You have the design, you need the build
Many SaaS companies have an in-house designer or a design from another studio. INSAIM builds a corporate website in Webflow or Framer from your design from $5,000, typically in 3 to 4 weeks. Design alone starts at $4,500 (4 to 6 weeks).
After launch: new pages and ongoing changes
A SaaS website is never finished: new features need pages, campaigns need landing pages, pricing changes. The INSAIM subscription for website and product work, including Webflow and Framer development, costs $3,900 a month with a one-month minimum. A lighter tier for marketing design (decks, ads, social, white papers) starts at $2,200 with a two-week minimum.
Market ranges for a SaaS website
| Option | Typical price | Good for |
|---|---|---|
| Freelancer or template | the lowest, often a few thousand dollars | a first landing page, a tight budget |
| Small studio, semi-custom | $5,000-15,000 | pre-seed to Series A teams that need design and build from one team |
| Agency, fully custom | $15,000-50,000+ | larger sites, many stakeholders |
| Specialist SaaS agency | $15,000-60,000+ | scale-ups with complex sites, many integrations, enterprise plans |
INSAIM sits in the second group: a 15+ person team in Lisbon working with SaaS, AI and tech startups, with fixed-scope projects from $2,500.
What pages a B2B SaaS website needs
The number of pages and templates is the biggest single driver of price. Here is what a typical seed to Series A SaaS site includes, with the stage at which each page is usually needed:
| Page | What it is for | Needed from |
|---|---|---|
| Home | Explains the problem, the product and who it is for in seconds | Every stage |
| Product or platform | Shows how the product works, often with animation or a demo | Seed |
| Pricing page | The page buyers compare first; plans, FAQ, a clear next step | Seed |
| Solutions by role or industry | Speaks to each buyer in their own words | Series A |
| Integrations | Answers "does it work with our stack?" | Series A |
| Security and compliance | SOC 2, ISO 27001, GDPR; essential for enterprise deals | Series A |
| Customer stories | Proof from named customers, usually a CMS collection | Seed |
| Blog or resources | Search and AI visibility, usually a CMS collection | Seed |
| Book a demo or start a trial | The conversion page, connected to your CRM | Every stage |
| About, careers, legal | Trust and hiring | Seed |
A pre-seed site can cover most of this on one page. A seed site usually has 5 to 8 pages. A site with solutions, integrations and a resource library reaches 15 to 20 pages, which at INSAIM usually comes closer to $15,000.
What is included in a SaaS website project
Two quotes for the same price can include very different things. Ask for each of these in writing. For every item below, the question to ask a studio comes first, then what INSAIM does.
| Item | What to ask | INSAIM |
|---|---|---|
| Structure and wireframes | Is there a sitemap and wireframe stage before design? | Included |
| Visual design | How many templates and pages are designed? | Included |
| Responsive build | Desktop, tablet and mobile? | Included |
| CMS for the marketing team | Which collections: blog, customer stories, integrations, careers? | Included, number of collections agreed in scope |
| Basic SEO | Titles, meta descriptions, alt text, sitemap | Included |
| Analytics, forms and CRM | Demo and trial forms routed to HubSpot or your CRM | Included |
| Redirects | 301 redirects from old URLs when you redesign | Included |
| Rounds of revisions | How many per stage? | Up to 2 rounds per stage |
| Copywriting | Full copy or copy direction only? | Copywriting included |
| Training | A walkthrough or video so your team can run the CMS | Included |
| Post-launch support | What is fixed for free after launch? | We fix our own bugs at no cost. New changes are billed hourly. |
What makes a SaaS website different
- It sells a product people cannot see. Buyers judge an abstract product from the site, so it needs to show the product working: interface shots, product animations, explainer videos or a live demo.
- It is built for demo and trial conversion. Every page leads to one next step, and that step is wired to your CRM.
- The pricing page carries a lot of weight. It is often the most visited page after the homepage and the one buyers compare across vendors.
- Marketing runs it, not developers. A modular CMS and reusable components let the team publish pages, customer stories and posts without a ticket.
- It has to be fast. Speed affects conversion, search rankings and how AI assistants read the site.
Full rebuild or page-by-page redesign?
Not every SaaS company needs a new website. The choice changes the budget more than anything else.
Rebuild the whole site when the brand has changed, the platform holds you back (no CMS, slow, every edit needs a developer), or the structure no longer matches the product. This is a corporate website project: at INSAIM from $8,000, typically 8 to 12 weeks.
Redesign page by page when the brand and platform still work, but key pages are outdated or new products need their own pages. This costs less upfront and keeps the site live throughout. For Dohop, which builds booking technology for airlines, we designed four new pages in their existing brand identity and built them in Webflow. Work like this fits a fixed-scope project or the $3,900-a-month subscription.
What drives the price of a SaaS website
- Pages and templates. Twenty pages built from five templates cost less than twenty unique pages.
- CMS collections. Blog, customer stories, integrations, careers and a resource library each need their own template and fields.
- Product animation and video. Lottie animations, 3D and product explainers make an abstract product clear, and add design and build time.
- Integrations. HubSpot or another CRM, analytics, a booking tool, or live product data through an API.
- Localisation. Each extra language adds content, layout checks and a platform add-on.
- Migration and redirects. The number of old URLs to map when you replace an existing site.
- Brand. Building on an existing brand is faster than designing one at the same time.
How long a SaaS website takes
Typical timelines at INSAIM:
| Service | Typical timeline |
|---|---|
| Landing page, design and build | 3-5 weeks |
| Startup pack, brand identity and landing page | 4-8 weeks |
| SaaS marketing website, design and build | 8-12 weeks |
| Website design only | 4-6 weeks |
| Website build from your design | 3-4 weeks |
The main variables are scope and how quickly content and feedback arrive. Timelines for a full website are indicative rather than fixed.
SaaS websites we have built
We do not publish what individual clients paid, but each of these projects maps to a package with a public starting price.
- Exaforce, an AI-driven SOC platform, USA. The client's team designed the site; we built it in Webflow and added motion, product explainers and a 3D model that make a complex security product easy to grasp. The site has 20+ pages and 10+ CMS collections built from reusable components, so the marketing team runs it without developers.
- Spiral, a B2B SaaS company. Brand identity, website design and the build in Webflow from one team, including an API integration that runs a live product demo in the hero section. Launched in four weeks.
- Carlogs, an automated mileage logging platform for individuals and businesses, Australia. We built their Webflow site from the client's design, with custom animation and micro-interactions that make the product feel smart.
- Dohop, travel tech for airlines, Iceland. Four new pages designed in their existing brand identity and built in Webflow, with custom illustrations.
- Scytale, a compliance automation platform for SaaS companies, USA. Their site runs on WordPress with their own developers; we work with them on subscription, designing individual web pages, decks and white papers. We refreshed a 47-slide deck in four days, then kept going with pages and new decks.
Webflow or Framer for a SaaS website?
At INSAIM the build prices are the same on both. Webflow has the stronger CMS for SaaS sites with many customer stories, integrations pages, a resource library or several languages. Framer is often faster for animated, launch-led sites at pre-seed and seed. We recommend the platform at discovery. For platform costs and details, see How much does a Webflow website cost in 2026 and How much does a Framer website cost in 2026.
