Making your company readable by AI. Outside, and in. AI search optimisation · The complete price list
Every price we have, down to the last unit
The headline prices are on the Pricing page and the Foundation page. This page publishes the rest: every unit that could ever appear on a HENUSSE quotation, with its price and the reason for that price. If it is not here, it cannot be ordered.
Price list version 1.0, published on 11 August 2026. Prices exclude VAT and have been effective since 5 August 2026. An accepted quotation is frozen for its scope: a change to the price list never applies to an order already under way.
The rule that governs everything
A HENUSSE quotation is a sum, never a surprise
A HENUSSE quotation is a sum: the prices on this page, applied to your scope. Nothing is improvised on an invoice: a line that is not on this price list is never added along the way.
And if your need fits none of these lines? We are a small firm, built for exactly that: we study it, we price it during scoping, and its price enters a new dated version of the price list before your quotation, publicly, at the same price for the next client.
Charges from third parties, hosting, licences, sources, rooms, never pass through us: you pay them directly, with no advance and no rebilling.
Foundation
What the special situations of the Foundation cost
In addition to the public fixed prices on the Foundation page: website build €11,500, existing-site rebuild €12,000, AEO setup only from €5,000, page in scope €1,400.
| Unit | Price | Why this price |
|---|---|---|
| Extraction from a locked platform, export and mapping of up to 50 addresses | €1,400 excl. VAT | The work of one page in scope: when your platform has no “export” button, every page of the old website has to be recovered by hand before anything can be rebuilt. |
| Each address extracted beyond 50 | €20 excl. VAT | A single act of recovery, not a page treatment. |
| Series template, the mould for a catalogue | €1,400 excl. VAT | The mould is priced as a page in scope: structure, buyer questions, structured data wired to fields. |
| Each product page cast from the template | €28 excl. VAT | The page poured into the mould: field mapping, sample checking, schema validation. A price measured on our own pilot, not estimated. The pilot’s exact date and volume are not established by published evidence. |
| Data source to clean up or import | €700 excl. VAT | Half a day: squaring up a messy file before the import. |
| Website version in a first added language, per page in scope | €700 excl. VAT | Half the price of a new page: the structure and the schemas already exist, so the first language pays for the voice glossary and the language scaffolding. |
| Each further language, per page in scope | €550 excl. VAT | The scaffolding is already paid for, and the next language is poured into it. |
We never certify another provider’s foundation from paperwork: it is impossible to stand behind the quality of work we did not do. The only route is the Diagnostic, then the eligibility audit, at public prices. Only a HENUSSE Foundation less than twelve months old is recognised, after a free check.
Monthly programme
What one more language costs, every month
In addition to the public tiers on the Pricing page: Essential €1,500, Authority €3,500, Sovereignty €10,000 per month.
| Unit | Price | Why this price |
|---|---|---|
| Language added to the Essential tier, per language per month | +€490 excl. VAT | Every month, every language translates and adapts all of that month’s articles and follows its own set of measured questions. Nothing spreads out over time: the price is the same for the second and the third language. |
| Language added to the Authority tier, per language per month | +€1,190 excl. VAT | Instead of €1,960 for four articles: translating a batch costs less than four separate translations, and we pass that on. |
| Language on the Sovereignty tier | included | Two or three languages are included in the price. |
Off-site authority
What an off-site campaign costs, on request
In addition to the public off-site foundation: €2,500 once, included on the Sovereignty tier.
| Batch | Price | Why this price |
|---|---|---|
| Small batch: 5 leads researched, up to 3 submissions, two follow-ups each, report | €1,200 excl. VAT | The initial research spreads badly over three submissions. |
| Medium batch: 10 leads, up to 6 submissions | €2,000 excl. VAT | The unit price falls as the volume rises. |
| Large batch: 15 leads, up to 10 submissions | €2,500 excl. VAT | The same volume as the foundation, the same price. The Sovereignty tier has its quarterly campaign included and does not need these batches. |
Website maintenance
What pushes the monthly maintenance fee up
The base at €300 excl. VAT per month: a WordPress brochure website, one language, up to 30 pages and 20 plugins, one hour of changes per month.
| Your website has… | Per month | Why |
|---|---|---|
| more pages, per block of 30 | +€50 excl. VAT | More pages means more monitoring and more updates. |
| more plugins, per block of 10 beyond 20 | +€50 excl. VAT | Every plugin is a risk to follow. |
| one more language | +€50 excl. VAT | Everything exists twice. |
| a maintained staging environment | +€100 excl. VAT | A second website to keep up to date. |
| a second brochure website | +€250 excl. VAT | Almost a second base: very little is shared. |
| heavy traffic, per block of 100,000 monthly page views beyond the first 100,000 | +€100 excl. VAT | Monitoring and incidents rise in proportion. |
| a server to administer, other than shared hosting | +€200 excl. VAT | The host no longer does the system work: we do. |
| a weekly review instead of a monthly one | +€150 excl. VAT | Four times as many passes. |
| one more hour of changes each month | +€90 excl. VAT | The webmastering hourly rate. |
Basket, payment, booking or customer account: that is e-commerce, a separate offer priced before any work starts. Handover beyond the session included: €90 excl. VAT per hour.
AI integration
What changes the size of the project and its support
The project, from €12,000 excl. VAT, covers one workflow, one team, one site, one language, one data source, one output. The exact amount is set during scoping, never below that floor.
| Your project has… | One-off | Why |
|---|---|---|
| one more workflow, same architecture | +€3,000 excl. VAT | A quarter of a project: the architecture is already paid for. |
| one more data source | +€1,500 excl. VAT | Every connection has to be built and tested. |
| one more output interface | +€1,500 excl. VAT | The same logic on the output side. |
| one more team or one more site | +€1,000 excl. VAT | Deployment and training done twice. |
| one more language in the workflow | +€500 excl. VAT | Prompts and checks done twice. |
| heavy volume, per block of 10,000 records beyond the first 10,000 | +€800 excl. VAT | Testing and migration rise in proportion. |
| one more role or authentication method, beyond two | +€600 excl. VAT | Permissions and security to build. |
Support, from €400 excl. VAT per month, covers one workflow, five users, two monitored components and two hours of intervention. Beyond that: workflow +150, five users +75, component +50, hour +100, weekly review +150, handover €100 excl. VAT per hour.
Training
The shorter formats, and what they cost
In addition to the public prices: full day €1,400.
| Format | Price | Why |
|---|---|---|
| Half day of 3 hours 30 | €800 excl. VAT | 57% of the full day: the preparation does not halve. |
| Two-hour session | €450 excl. VAT | The same logic. |
| Each participant beyond ten, per session | +€60 excl. VAT | Materials, exercises and individual attention. |
| Full adaptation of a format into English | +€300 excl. VAT | The only other language we deliver as a matter of course. |
Travel
What is included, and what is charged beyond it
Travel is included within a road radius of 100 kilometres around Le Mené, which covers Saint-Brieuc, Dinan, Saint-Malo, Rennes and Vannes among others.
Beyond that: €0.70 excl. VAT per return kilometre beyond 200 kilometres in total, and €70 excl. VAT for each hour of driving started beyond two hours there and back. Time on the road is not delivered work, but it is not free either: we charge it at half a day rate.
Tolls, meals and accommodation at cost, within a written cap, once agreed.
Published prices
A dated price list, and an order that keeps its terms
Prices exclude VAT. A higher quotation than someone else’s carries more units, never a different rate.
This page is versioned: every change carries a new date, and an order already under way keeps its terms. The headline prices are on the Pricing and Foundation pages.
