The verdict in three sentences
A public website tender is won on the technical proposal, not the price: the common 2026 weighting is 60% technical / 40% price, so undercutting is never enough. The three disqualifying requirements, in France and beyond, are accessibility (RGAA 4.1 / WCAG AA), data sovereignty (SecNumCloud or EU hosting), and GDPR compliance. Aim for a realistic budget of EUR 20,000-90,000 by scope and polish every scored criterion rather than underpricing.
The unavoidable regulatory requirements
A public body applies obligations the private sector often ignores. Failing to address them in the technical proposal means elimination before the price is even scored.
| 2026 requirement | What it imposes | Impact on the bid |
|---|---|---|
| Accessibility RGAA 4.1 / WCAG AA | AA compliance, published statement | Audit + fixes: +EUR 5,000-15,000 |
| Sovereign hosting | SecNumCloud or EU host | Higher recurring cost |
| GDPR & data | Register, DPO, minimization | Mandatory documentation |
| Reversibility | Return of data and code | Contract clause |
| Eco-design | RGESN framework | Scoring differentiator |
| Multilingual | Local + community languages | +EUR 1,500-4,000 |
The typical scoring grid
Understanding the grid before writing lets you spend effort where points are won. Here is a representative 2026 public-body weighting.
| Criterion | Weight | What earns points |
|---|---|---|
| Technical value | 40% | Precise proposal, mockups, methodology |
| Accessibility & quality | 20% | Quantified WCAG commitment, user testing |
| Price | 40% | Coherent, neither underpriced nor excessive |
| Timeline & planning | Sub-criterion | Realistic schedule with milestones |
| Similar references | Sub-criterion | Comparable public projects delivered |
Mini case study
Nadia, who runs an 8-person agency in Marseille, bids on a public redesign, estimated budget EUR 55,000. Tempted to undercut to EUR 38,000, she does the math: price is only 40%, and her technical offer is strong. She proposes EUR 49,000 with a detailed proposal, a quantified accessibility commitment, and two public-sector references. She scores 17/20 technical and 15/20 price, beating the lowest bidder at EUR 38,000 whose technical score caps out. Tender won, margin preserved by about EUR 11,000.
FAQ
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Do you always have to be the cheapest?
No. With 60/40 weighting favoring technical value, a price that is too low raises feasibility doubts and cannot offset a weak proposal.
What is RGAA 4.1?
The French general accessibility framework, mandatory for the public sector. It requires WCAG level AA compliance and a published accessibility statement.
Is SecNumCloud mandatory?
Not always, but increasingly required for sensitive data. Otherwise, GDPR-compliant EU hosting is the minimum expected.
How long to prepare a response?
Budget 5 to 15 person-days depending on scope: technical proposal, mockups, planning, administrative documents, and reference sourcing.
Can a small agency win?
Yes, with an excellent technical proposal and relevant references. A temporary consortium also lets you pool missing skills.
