The verdict in three sentences
On the same brief, the gap between three redesign quotes commonly reaches 40 % in 2026 in Amsterdam. That gap is almost never margin: it comes from missing lines (content, technical SEO, training) that reappear as overruns. The rule: compare on strictly identical scope, and demand the 12 lines below before signing.
The 12 lines of a readable quote
A serious quote itemises the budget by line. Here is the 2026 reading grid with the indicative weight of each line on a 12,000 EUR project.
| Line | What it covers | Indicative share |
|---|---|---|
| 1. Scoping & workshop | goals, sitemap | 8-10 % |
| 2. UX/UI design | mockups, design system | 15-25 % |
| 3. Front-end build | responsive HTML/CSS | 15-20 % |
| 4. Development | CMS, back-office, forms | 15-20 % |
| 5. Content & copy | text, migration | 10-15 % |
| 6. Technical SEO | tags, perf, redirects | 8-12 % |
| 7. QA & testing | cross-browser, mobile | 5-8 % |
| 8. Training | CMS handover | 2-4 % |
The four remaining lines cost little but protect you: 9. warranty (3-6 months), 10. late penalties, 11. source-code and access ownership, 12. reversibility plan (retrieving your site with another vendor).
The traps that blow up the invoice
Some items are deliberately vague to show a low price. Here are the 2026 benchmarks to spot them.
| Watch point | 2026 benchmark | Risk if absent |
|---|---|---|
| Deposit requested | 30-40 % | > 50 % = cash-flow risk |
| Pages included | precise number | extra pages billed |
| Revision rounds | 2-3 included | each round billed |
| Content migration | fixed or actual | frequent overrun |
| Code ownership | you, exclusive | vendor lock-in |
| 301 SEO redirects | included | traffic loss post-redesign |
A quote 20 % cheaper that excludes content migration, SEO redirects and training often ends up more expensive once overruns are billed. Compare the full cost, not the entry price.
Mini case study
Karim runs a building-materials trading SME in Amsterdam. He receives three quotes for the same 14-page redesign: 8,900 EUR, 11,400 EUR and 12,600 EUR.
Applying the grid, he finds the 8,900 EUR quote excludes content migration (estimated 1,500 EUR), SEO redirects (800 EUR) and training (600 EUR), and does not transfer code ownership. Reconstructed real cost: 11,800 EUR, still without reversibility. The 11,400 EUR quote, complete and with code ownership, becomes the most competitive. The grid saved him a false 2,900 EUR saving.

FAQ
Why do three quotes for the same project vary so much?
The average 2026 gap reaches 40 % on identical stated scope. The difference lies in omitted lines: content, SEO, training, warranty. A low price often hides future overruns.
What deposit is reasonable?
Between 30 and 40 % at order, with an intermediate milestone and the balance on acceptance. Above 50 % deposit, negotiate: you carry too much cash-flow risk.
Should I demand source-code ownership?
Yes, always. Without an exclusive ownership clause and handover of access, you remain dependent on the vendor for any evolution or agency change. It is the most strategic line in the quote.
Are SEO redirects really necessary?
Essential. A redesign without 301 redirects of old URLs can lose 20-40 % of organic traffic for several months. Check this line appears on the quote.
What does the post-delivery warranty cover?
A 3-to-6-month warranty covers free correction of bugs and defects. Distinguish it from maintenance (evolutions and security), which is a separate monthly contract.
