The verdict in three sentences
For a B2B SaaS company with USD 1 to 5 million in ARR, the marketing site is a sales asset: it must generate qualified demo requests, not just describe the product. A budget of USD 22,000 to 55,000 (EUR 20,000 to 50,000) over 8 to 12 weeks covers a fast site, a headless CMS your marketing team runs on its own and a proper A/B testing setup. Choosing between Webflow and Next.js depends on how many landing pages you ship and how strict your performance needs are.
What a B2B SaaS marketing site costs in 2026
Price gaps mainly come from the number of templates, CRM integration (HubSpot, Salesforce) and the depth of measurement. These are 2026 ballpark figures for a growth-stage SaaS company in Austin.
| Item | 2026 range (excl. tax) | Indicative timeline |
|---|---|---|
| Strategy, messaging and site map | USD 3,300 to 7,700 (EUR 3,000 to 7,000) | 2 weeks |
| UI design (8 to 15 templates) | USD 6,600 to 15,400 (EUR 6,000 to 14,000) | 3 weeks |
| Next.js build + headless CMS | USD 8,800 to 22,000 (EUR 8,000 to 20,000) | 4 to 5 weeks |
| CRM integration, forms and demo booking | USD 1,650 to 4,400 (EUR 1,500 to 4,000) | 1 week |
| A/B testing, analytics and dashboards | USD 1,650 to 5,500 (EUR 1,500 to 5,000) | 1 week |
| Extra landing page | USD 900 to 2,200 each (EUR 800 to 2,000) | 3 to 5 days |
| Total project | USD 22,000 to 55,000 | 8 to 12 weeks |
Austin's software scene pushes founders toward very technical websites. The classic trap: a site full of product jargon with no clear path to a demo. The messaging budget is often the one with the highest return.
Conversion benchmarks: what a good site should deliver
A B2B SaaS site is judged on how well it turns traffic into pipeline. Use these benchmarks to set contractual goals with your vendor.
| Metric | Average site | Optimized 2026 site |
|---|---|---|
| Visitor to demo request rate | 0.5 to 1% | 1.5 to 3% |
| Paid landing page to demo rate | 2 to 4% | 6 to 10% |
| Mobile load time (LCP) | 3.5 to 5 s | under 2 s |
| Share of qualified demos (SQL) | 30 to 40% | 50 to 65% |
| Cost per demo via Google Ads | USD 275 to 500 | USD 130 to 240 |
| Time to publish a landing page | 2 to 3 weeks | 1 to 2 days |
Moving from 0.8% to 2% conversion on 6,000 monthly visitors means 72 more demos per month. With a 15% close rate and a USD 13,000 ACV, the impact far exceeds the cost of the site.
Webflow or Next.js: the right choice for your stage
| Criterion | Webflow | Next.js + headless CMS |
|---|---|---|
| Build cost | USD 13,000 to 33,000 | USD 22,000 to 55,000 |
| Annual subscription | USD 550 to 2,750 | USD 0 to 3,300 (hosting + CMS) |
| Marketing autonomy | Very high | High with predefined components |
| Core Web Vitals performance | Good | Excellent |
| Product integrations (docs, dynamic pricing) | Limited | Unlimited |
| Native A/B testing | Through third-party tools | Server-side, no flicker |
| Portability | Low | Full, you own the code |
Webflow suits a company that publishes many pages and wants speed with a small team. Next.js wins once the site must show documentation, calculated pricing, several languages or rigorous server-side tests.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas, CEO of an industrial maintenance SaaS company in Austin (USD 3 million ARR), gets 5,000 visitors a month and converts at 0.7%, or 35 demos. After a Next.js rebuild at USD 42,000 and 10 industry landing pages, his rate rises to 2.1%, or 105 demos. With 55% qualified demos and a 14% close rate on a USD 16,500 ACV, the 70 extra demos generate about 5.4 more deals per month. On this estimate, the site pays for itself in less than one month of signings.
FAQ
How much does an extra landing page cost after launch?
Expect USD 900 to 2,200 depending on customization. With a well-designed component library, your marketing team can also assemble them alone in 1 to 2 days.
How long does a complete B2B SaaS site take?
Between 8 and 12 weeks for 8 to 15 templates. Projects that slip are usually stuck on messaging approval, which is why it should be settled in the first 2 weeks.
Does a Series A company need a headless CMS?
Yes if you publish more than 4 landing pages a month or run 2 languages. A CMS like Sanity costs USD 0 to 16,500 a year depending on volume and cleanly separates content from code.
What conversion rate should we target in year one?
A realistic goal is 1.5% at launch, then 2.5 to 3% after 6 months of A/B testing. Below 1%, the problem is usually the value proposition, not the design.
Can the site lower our acquisition cost?
Yes, a dedicated landing page per campaign often brings cost per demo from USD 330 to under USD 220. On 40 paid demos a month, that saves about USD 4,400 monthly.
