Writing a B2B Website Brief/RFP: Template and Budget 2026 (Amsterdam)

The verdict in three sentences

A precise brief (RFP) is the strongest negotiating lever in a B2B web project: without one, three agencies will bid on three different projects and your quotes will vary by 40%. With a structured brief, the spread drops below 10% and you finally compare like-for-like offers. Budget 1,000 to 3,000 EUR for an assisted write-up and 2 to 3 weeks of scoping before you launch the tender.

What the brief must contain

A useful B2B brief is not a novel: it is a decision grid. Every section must let the agency price the work without coming back to you ten times. Here is the minimum structure and the indicative budget weight of each block.

The classic trap: leaving the functional scope vague. A cautious agency will price high to cover itself; another will price low then bill change orders. The brief closes that door.

Target budget and realistic 2026 timelines

State a target budget in the brief. Contrary to popular belief, this does not inflate prices: it screens out agencies outside your range and focuses proposals on your reality. Here are 2026 ballpark figures for a B2B corporate website in Amsterdam and across Europe.

Always add a weighted selection criteria clause: price 30%, sector references 25%, methodology 20%, support 15%, timelines 10%. Sharing this grid with candidates mechanically improves the quality of responses.

Mini case study

Sophie, marketing director at an industrial-software vendor in Amsterdam, must compare 3 agencies. Without a brief, her first quotes swing between 11,000 and 27,000 EUR: impossible to arbitrate. She invests 2,200 EUR in an assisted 18-page brief and re-runs the tender. The new quotes land between 17,500 and 20,800 EUR, a 19% spread instead of 145%. The brief saved her roughly 3 weeks of clarification meetings and avoided an estimated 4,000 EUR change-order risk. Immediate ROI: the document pays for itself in the first negotiation.

FAQ

How much does writing a brief cost in 2026?

An assisted write-up by an agency or consultant runs between 1,000 and 3,000 EUR depending on complexity. This cost is often creditable against the final project if you hire the same vendor.

Should you state your budget in the RFP?

Yes. Showing a target budget cuts the spread across received quotes from 40% to 10% and avoids wasting time with out-of-range agencies. You keep control of the negotiation.

How long does scoping take before launching the tender?

Allow 2 to 3 weeks for a solid brief, internal interviews included. This delay is more than offset by fewer back-and-forths during the project.

How many agencies should you consult?

Three well-selected candidates are enough. Beyond that, analysis time explodes without quality gains. Use a weighted criteria grid to decide objectively.

What if the scope changes mid-project?

Include a priced change-order clause in the brief (reference day rate and procedure). Without a framework, a scope change costs on average +30% over the initial quote.
