The verdict in three sentences
For a 150-employee cleaning contractor targeting factories, warehouses and cleanrooms, a serious B2B website costs 5,000 to 12,000 EUR excl. VAT in Dublin in 2026. Most of the budget should go to sector and certification pages (ISO 9001, ISO 14001, ISO 45001) and to a floor area calculator that qualifies the enquiry before the first call. With a B2B cost per lead of 60 to 150 EUR in paid ads, every conversion point gained on the site pays back the investment quickly.
What a 5,000 to 12,000 EUR quote includes
The gap between the two figures has little to do with design. It depends on how many sectors are covered in depth, how rich the calculator is and how tightly the site connects to your sales tools. An industrial buyer compares three or four contractors online before issuing a tender: your site has to give them the proof they want without picking up the phone.
| Item | Essential version | Full version |
|---|---|---|
| Architecture, mockups and branding | 1,000 EUR | 2,200 EUR |
| Sector pages (manufacturing, logistics, cleanrooms, food processing, offices) | 3 pages, 900 EUR | 6 pages, 2,400 EUR |
| Certification and commitment pages (ISO 9001, ISO 14001, ISO 45001, Safe-T-Cert) | 400 EUR | 1,000 EUR |
| Floor area calculator and quote form | 800 EUR | 2,000 EUR |
| Local SEO copywriting (Dublin, Ballymount, Clondalkin, Blanchardstown, Swords) | 700 EUR | 1,800 EUR |
| CRM integration and conversion tracking | 500 EUR | 1,400 EUR |
| Testing, launch and training | 700 EUR | 1,200 EUR |
| Total (excl. VAT) | 5,000 EUR | 12,000 EUR |
These amounts are 2026 ballpark figures for freelancers and mid-sized agencies. A quote below 4,000 EUR usually means a generic theme with no written sector pages and no calculator.
The pages that get an industrial buyer to sign
Your counterparts are facilities managers, HSE managers and quality managers. In a cleanroom they think in ISO 14644 classes and decontamination protocols. In a logistics warehouse they think scrubber-dryers, night shifts and working alongside forklift drivers. A single services page answers none of them.
Each sector page should present the standard protocol, proposed frequencies, equipment used, traceability (service reports, joint quality audits) and a costed use case. Add a supplier documents page listing what you send within 48 h: tax clearance certificate, public and employer liability insurance, current ISO certificates, a sample safety statement. That page reassures a buyer preparing a supplier listing.
The floor area calculator and the real cost of a lead
The calculator asks for the area in square metres, the site type, the desired frequency and special constraints (ATEX zone, ISO class 7 cleanroom, work at height). It displays an indicative range and offers a site survey. The result: fewer off-target enquiries and sales reps who arrive at the meeting with the right information.
| Channel | B2B cost per lead 2026 | Lead to contract rate | Acquisition cost per contract |
|---|---|---|---|
| Google Ads (industrial cleaning Dublin) | 80 to 150 EUR | 10 % | 800 to 1,500 EUR |
| LinkedIn Ads (facilities, HSE) | 100 to 150 EUR | 8 % | 1,250 to 1,875 EUR |
| Google and Meta retargeting | 60 to 90 EUR | 6 % | 1,000 to 1,500 EUR |
| Local SEO after 6 to 9 months (estimate) | 20 to 50 EUR | 12 % | 170 to 420 EUR |
| Private and public tenders | Sales time | 15 to 25 % | Variable |
| Referrals and word of mouth | 0 EUR direct | 30 % | Close to zero |
The lesson is simple: the site first lowers your paid cost per lead, then builds organic traffic that costs four to five times less. Without well-written sector pages, local SEO never takes off and you stay dependent on ads.
Mini case study

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Siobhan, sales director of a 150-employee cleaning contractor in Clondalkin, invests 9,000 EUR in a new website. She spends 2,000 EUR a month on Google Ads. The old site converted 1.5 % of visitors, a cost per lead of 120 EUR and about 16 enquiries a month. The new site, with its calculator, reaches 3 %: the cost per lead drops to 60 EUR and volume rises to 33 enquiries on the same budget.
With a 5 % close rate, she goes from 0.8 to 1.65 contracts a month. An average contract is worth 36,000 EUR a year with a 12 % net margin, or 4,320 EUR. Two extra contracts pay for the site: the investment is recovered in under three months, provided the team calls back every enquiry within 24 h.
FAQ
How long does it take to deliver a site like this?
Allow 6 to 10 weeks depending on the number of sector pages and how quickly your team validates protocols. Copywriting is usually the bottleneck: plan a 2 h interview per sector with your operations manager.
Should prices appear on the site?
An indicative range from the calculator is enough, with a note that it is subject to a site survey. It filters out enquiries that are too small, for example under 300 square metres, without any contractual commitment.
How should certifications be showcased?
Create a dedicated page with logos, certificate numbers, expiry dates and what each certification guarantees the buyer. That page costs 300 to 600 EUR and answers a question found in most tender documents.
What ad budget should we plan at launch?
For the Dublin area, 1,500 to 3,000 EUR a month for 3 months is enough to measure your real cost per lead. Add 10 to 15 % in management fees if an agency runs the campaigns.
What does the site cost once live?
Hosting, security updates and small changes run 80 to 250 EUR a month on the market. Also plan 2 to 4 new pages or case studies a year to keep your rankings growing.
