The verdict in three sentences
For a rental company running 90 vans in Amsterdam, a website with a custom booking engine costs roughly 25,000 to 70,000 EUR ex VAT in 2026, versus 150 to 450 EUR a month for off-the-shelf rental SaaS. Over three years, SaaS stays cheaper below about 60 vehicles, but beyond that custom wins as soon as you need negotiated business rates, card pre-authorisation deposits and monthly invoicing for trade accounts. The real financial lever is not the website itself but the utilisation points gained: going from 65 to 75 % is worth more than the project budget.
What a tradesperson or SME expects from your site
A plumber in Amstelveen or a removals firm in Zaandam does not read your About page. They want to know in thirty seconds whether a 12 m³ van is free on Thursday, at what price, and whether they can collect it at 7 am from the Westpoort depot. The specification follows from those three questions.
| Module | Key function | Share of budget (2026 estimate) |
|---|---|---|
| Fleet catalogue | Pages per category (3 m³, 12 m³, 20 m³, dropside, refrigerated) | 10 % |
| Real-time availability | Calendar by depot and category | 20 to 25 % |
| Dynamic pricing | Day, weekend, week, month, included kilometres | 15 % |
| Payment and deposit | iDEAL and cards via Mollie or Adyen, 300 to 1,000 EUR pre-authorisation | 15 % |
| Business accounts | Multi-user accounts, negotiated rates, monthly invoice | 15 to 20 % |
| Depot back office | Check-in, check-out, condition photos, damage | 15 % |
| Dutch and English versions | Bilingual, depot WhatsApp numbers | 5 % |
The deposit is the sensitive point. iDEAL is the default payment method in the Netherlands, but it cannot hold a pre-authorisation. The site must therefore take the rental payment by iDEAL and the deposit by credit card, or offer a deposit-free option for verified business accounts.
Custom engine or rental SaaS: the three-year math
| Item | Rental SaaS | Custom website |
|---|---|---|
| Setup | 5,000 to 12,000 EUR (website and configuration) | 25,000 to 70,000 EUR |
| Monthly subscription or maintenance | 150 to 450 EUR | 300 to 600 EUR |
| Commission per booking | 0 to 3 % depending on vendor | 0 % |
| Payment fees | 0.29 EUR per iDEAL, 1.8 % or more per card | Same |
| Negotiated business rates | Often limited | Unlimited, per customer |
| Customer data ownership | With the vendor | With you |
| Total 3-year cost (90 vans) | 10,000 to 30,000 EUR (before commissions) | 36,000 to 92,000 EUR |
SaaS wins if your customers are mostly consumers renting occasionally. Custom makes sense once 40 % of revenue comes from recurring business accounts, because every trade contract that a standard tool handles badly ends up managed by hand, by phone and in spreadsheets.
What one utilisation point is worth
| Indicator | Current situation | 12-month target |
|---|---|---|
| Fleet | 90 vans | 90 vans |
| Average daily rate | 75 EUR | 75 EUR |
| Utilisation | 65 % | 70 to 75 % |
| Rental days per year | 21,350 | 23,000 to 24,600 |
| Share of online bookings | 25 % | 55 to 65 % |
| Phone booking time | 12 minutes | 3 minutes (check only) |
| Annual rental revenue | 1.6 M EUR | 1.7 to 1.85 M EUR |
A single utilisation point represents about 328 rental days, close to 24,600 EUR a year for this fleet. The website does not create all of the increase, but it captures evening and weekend demand that the phone line misses.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Daan, managing director of a 90-van rental company in Amsterdam with two depots, loses around twenty requests a week that arrive after 7 pm. He picks the custom option at 45,000 EUR plus 450 EUR a month of maintenance, so 61,200 EUR over three years. Cautious assumption: the site adds 3 utilisation points, 985 rental days at 75 EUR, about 73,900 EUR of revenue a year. At a 35 % contribution margin, the annual gain is around 25,900 EUR and once maintenance is deducted, the 45,000 EUR setup pays back in a little over two years. The depots also save close to 9 hours of phone time a week.
FAQ
How much does a van rental website with booking cost in Amsterdam?
As a 2026 estimate, 25,000 to 70,000 EUR ex VAT for a custom build, depending on depots and business accounts. SaaS costs 150 to 450 EUR a month plus a website.
Can I take a deposit online in the Netherlands?
Yes, through a credit card pre-authorisation of 300 to 1,000 EUR via Mollie, Adyen or Stripe. iDEAL cannot hold funds, so use it for the rental payment only.
How long does it take to launch the booking engine?
Allow 8 to 14 weeks for a custom build, versus 3 to 5 weeks for configured SaaS with a website.
Do I need an English version?
Yes in Amsterdam: expat-run businesses and international contractors are a large share of demand. A bilingual site adds about 5 to 10 % to the budget.
Is SaaS enough for a 90-vehicle fleet?
It is if customers are mainly consumers. Above 40 % business customers with negotiated rates, custom becomes more profitable over three years.
