B2B Brochure Website Requirements Spec Amsterdam 2026

The verdict in three sentences

A costed requirements spec is the most profitable tool of a web project: it cuts the quote by 20 to 30 % because it removes the uncertainty every agency prices in. In Amsterdam in 2026, a well-scoped B2B brochure site costs 5,500 to 9,000 EUR; the same vague project climbs to 10,500-12,000 EUR because of back-and-forth. A good spec fits in 8 to 12 pages and is structured around scope, sitemap, content, integrations, SEO and budget per section.

Spec structure and budget per section

Costing each line BEFORE the tender lets you compare three quotes on an identical basis, instead of comparing apples and oranges.

The rule: do not pay for the Growth version if your KPIs (fewer than 15 leads/month targeted) are reachable in Starter. The spec forces that discipline.

The 6 mistakes that inflate a quote

• Content not ready: the agency prices in copywriting (up to 2,700 EUR).
• "We'll see" scope: every uncertainty is priced at worst case.
• Integrations discovered mid-project: +30 to 50 % on the relevant line.
• Disorganised sign-offs: each week of delay costs coordination.
• Multilingual added later: rebuilding the i18n structure costs more than upfront.
• No project owner client-side: the number-one cause of budget drift.

Mini case study

Sophie, communications manager of a B2B consulting firm in Amsterdam, prepares her project. Without a spec, she receives three quotes at 9,800, 12,000 and 8,200 EUR, impossible to compare. She writes a 10-page spec (14-page sitemap, EN+other, HubSpot CRM, booking), spending 6 hours on it. Result: the three agencies re-quote on an identical basis at 7,600, 8,300 and 8,900 EUR. She picks 7,600 EUR instead of 9,800: 2,200 EUR saved for 6 hours of work, i.e. 367 EUR/hour. Content, prepared in-house, also avoids 1,900 EUR of copywriting.

FAQ

How long should a good brochure spec be?

Between 8 and 12 pages for a standard B2B project. Beyond that you over-scope and slow down; below it you leave too much uncertainty that the agency bills as a safety margin.

Is the spec paid for?

A serious agency often offers a discovery workshop at 900-1,700 EUR, deductible from the project if signed. Writing it yourself from a template is free and already lowers quotes.

Should it include a budget?

Yes, a range. Stating "6,500-8,500 EUR" steers proposals toward your reality and avoids off-target 15,000 quotes. Hiding the budget adds 2 to 3 weeks of exchanges.

What if the scope changes mid-project?

A good spec includes a change-order clause: any out-of-scope request is quoted separately (often 500-700 EUR/day). This protects both parties.

Can you request a quote without a spec?

Yes, but the quote will include a 15 to 30 % safety margin. On an 8,500 EUR project, that is 1,300 to 2,500 EUR you pay for uncertainty.
