The verdict in three sentences
For a B2B site where the marketing team wants to publish without a developer, Webflow is unbeatable between 4,000 and 12,000 EUR. As soon as you have business logic (configurator, client portal, deep integrations, high volumes), Webflow becomes a constraint and custom code at 12,000-30,000 EUR regains the edge. The real criterion isn't the upfront price but the complexity ceiling you'll hit within 18 months.
Full cost: Webflow vs custom code in 2026
In Amsterdam, 2026 ranges for a B2B site of 10-25 pages with a CMS.
| Line item | Webflow | Custom code |
|---|---|---|
| Design + UX | 3,000-6,000 EUR | 5,000-10,000 EUR |
| Build / dev | 2,000-6,000 EUR | 8,000-20,000 EUR |
| Platform subscription | 20-70 EUR/month | 0 (hosting 15-50 EUR/mo) |
| Delivery time | 4-7 weeks | 8-14 weeks |
| Upfront total (estimate) | 4,000-12,000 EUR | 12,000-30,000 EUR |
| 3-year recurring cost | 720-2,520 EUR | 540-1,800 EUR |
Webflow wins at purchase; over 3 years the subscription eats into part of the gap, but overall stays cheaper than a coded project.
Where Webflow hits a ceiling
Advanced no-code has a real technical ceiling. Here are the decision criteria.
| Criterion | Webflow edge | Custom-code edge |
|---|---|---|
| Editorial autonomy | Excellent (visual CMS) | Good (CMS to build) |
| Recurring cost | 20-70 EUR/mo fixed | Hosting only |
| Complex business logic | Limited (throttled logic/API) | Unlimited |
| Performance at scale (>50k visits/mo) | Good but capped | Freely optimisable |
| Deep integrations (ERP, CRM) | Via Zapier/API, fragile | Native, robust |
| Portability / reversibility | Limited HTML export | 100% your code |
| Content ceiling (CMS items) | 10,000-20,000 items | Unlimited |
The 2026 rule: if your need fits a CMS and forms, Webflow. If you handle business data, calculations, or target high volumes, custom code.

Mini case study
Sophie is marketing lead at an industrial mid-cap in Amsterdam, a catalogue of 400 technical references. She receives two quotes: Webflow at 9,500 EUR, custom code at 22,000 EUR. Custom looks expensive, but her need includes a product configurator and a nightly ERP sync. On Webflow, these two functions would run through Zapier workarounds at 89 EUR/month plus 3,000 EUR of fragile integration. Over 5 years, the patched Webflow would work out to roughly 20,300 EUR TCO with breakage risk at every update, versus 24,700 EUR for robust custom code. Sophie picks custom: for 4,400 EUR more over 5 years, she gets a reliable native integration instead of a fragile assembly. Verdict: once business logic is in play, the price gap is justified by reliability.
FAQ
Is Webflow really cheaper than custom code? At purchase yes, often by half (4-12k vs 12-30k EUR). Over 3-5 years, the subscription and technical limits can flip the equation for complex needs.
Will my team be able to publish on Webflow alone? Yes, that's its strength: the visual CMS lets a non-technical marketer create pages and articles without a developer, saving 3,000-6,000 EUR/year in dev interventions.
What are Webflow's real limits in 2026? Advanced business logic, deep integrations (ERP), and the CMS ceiling around 10,000-20,000 items. Beyond that, custom code becomes necessary.
Can we migrate from Webflow to custom later? Yes, but expect a near-full rebuild: Webflow export is limited. Anticipate it if you foresee strong growth.
What budget for a serious Amsterdam B2B site in 2026? 6,000-12,000 EUR in Webflow, 15,000-30,000 EUR in custom code depending on business complexity and integrations.
