The verdict in three sentences
A barge operator based at the Port of Strasbourg does not sell boats, it sells a lower cost per tonne-kilometre and lower emissions than road haulage. The website must therefore let a construction, grain or container shipper simulate a route, compare CO2 and request a quote in under three minutes. Budget 10,000 to 24,000 EUR excl. VAT for a trilingual FR/DE/EN site with a calculator, delivered in 8 to 10 weeks.
Why shippers still hesitate between barge and truck
The logistics director of a grain trader or a construction group knows trucking by heart: one call, one price, pickup tomorrow. Waterways look slow and opaque. Your website must reverse that perception with comparable figures, in the shipper's own language (a large share of Rhine shippers are German or Swiss).
| Criterion (2026 order of magnitude) | Rhine barge (2,500 t motor vessel) | 25 t truck | Gap for the shipper |
|---|---|---|---|
| Cost per tonne-km | 0.015 to 0.025 EUR | 0.07 to 0.10 EUR | 3 to 4 times cheaper by water |
| CO2 per tonne-km | 25 to 35 g | 80 to 110 g | 60 to 70% fewer emissions |
| Capacity per unit | 2,500 to 4,000 t (or 200 TEU) | 25 t (or 2 TEU) | 1 barge replaces 100 to 160 trucks |
| Strasbourg - Rotterdam lead time | 3 to 4 days | 1 to 2 days | Slower, but plannable |
| Exposure to tolls and restrictions | Low | Eco-tax, weekend bans | More stable cost |
| Low-water sensitivity | High in summer (10 to 40% surcharge) | None | Must be explained clearly |
This table, published on the site with cited sources, does more for conversion than any sustainability slogan. A shipper subject to CSRD reporting wants a number they can carry into their carbon accounts.
Website building blocks and budget
The heart of the project is the quote journey: origin, destination, cargo type, tonnage, frequency. The calculator instantly shows the emissions avoided versus trucking, then sends the request to sales with all qualified data attached.
| Building block | Content | Indicative budget excl. VAT |
|---|---|---|
| Trilingual FR/DE/EN core | 12 to 18 pages, design, CMS, hosting | 5,000 to 9,000 EUR |
| Barge vs truck CO2 calculator | Port distances, emission factors, PDF export | 2,000 to 5,000 EUR |
| Per-route quote request | Multi-step form, routing to sales, CRM | 1,500 to 3,500 EUR |
| Fleet and terminal pages | Vessel sheets (tonnage, draught, hold), map of ports served | 800 to 2,500 EUR |
| Sector pages | Construction, grain, containers, heavy lift | 700 to 2,000 EUR |
| Technical SEO and proofread translation | Hreflang, markup, native German copy | 1,000 to 2,000 EUR |
| Total | 10,000 to 24,000 EUR excl. VAT |
The low end covers a simple calculator based on fixed distances between about ten ports (Strasbourg, Basel, Mannheim, Duisburg, Rotterdam, Antwerp). The high end adds an indicative price estimate and a CRM connection with automated follow-up.
An 8 to 10 week schedule
| Week | Deliverable |
|---|---|
| 1 to 2 | Workshops with sales leadership, sitemap, fleet data collection |
| 3 to 4 | Desktop and mobile mockups, quote journey sign-off |
| 5 to 6 | Development, calculator, CRM integration |
| 7 | DE/EN translations proofread by native speakers, sector content |
| 8 to 9 | Testing, acceptance with three pilot shippers |
| 10 | Go-live, conversion tracking, targeted LinkedIn campaign |
What usually delays the schedule is collecting the fleet's technical data. Prepare it before kickoff.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas, sales director of an operator running 9 motor vessels at the Port of Strasbourg, invests 18,000 EUR excl. VAT in a trilingual site with a calculator. Within six months, the quote form receives 42 qualified requests, 5 of which become contracts. A single contract with an Alsatian grain trader covers 60,000 tonnes a year to Rotterdam, at a net margin of about 1.20 EUR per tonne, or 72,000 EUR of annual margin. That one client pays back the website in three months.
FAQ
Does the CO2 calculator need certification?
No, but it should cite its emission factors (ADEME database, EN 16258 or ISO 14083). A shipper reusing the figure in CSRD reporting will check the method, and a visible source noticeably increases quote requests.
Should prices be shown on the site?
An indicative range per tonne and per corridor is enough, with a note on low-water surcharges (10 to 40% in summer). Firm prices stay in the quote, which protects your negotiating margin.
Is a German version really necessary?
On the Rhine corridor, yes: most shippers and partner ports are in Germany, Switzerland and the Netherlands. A native-proofread translation costs 600 to 1,500 EUR and keeps you from losing half your market.
How long until the first requests?
Typically 4 to 8 weeks after launch, if the site is backed by a LinkedIn campaign targeting logistics directors (800 to 1,500 EUR per month).
Can the site connect to our fleet planning tool?
Yes, via an API or data export. Budget an extra 2,000 to 6,000 EUR excl. VAT depending on the tool, for example to display weekly hold availability.
