The verdict in three sentences
A B2B collection agency (incassobureau) in Amsterdam does not win corporate mandates with a pretty homepage, it wins them with hard evidence: a readable fee schedule, recovery rates by debt age and real timelines. The website that converts CFOs of SMEs and mid-caps combines a bad-debt cost simulator, a secure claim upload area and dedicated pages for each situation (amicable stage, court proceedings, cross-border claims). With Kolonell, the project costs 800,000 to 3,500,000 FCFA (1,220 to 5,340 EUR) depending on the Starter, Growth or Premium tier, delivered in 6 to 8 weeks.
What a CFO checks before handing over a mandate
A finance director outsourcing overdue invoices usually compares three agencies in under an hour. They skip your mission statement and look for precise answers. In the Netherlands, the Wet kwaliteit incassodienstverlening (Wki) has required collection agencies to be listed in the Justis register since April 2024, with rules on screening, staff training and the handling of client funds. Showing your registration, your NVI membership or Keurmerk Incasso label, and your professional liability cover reassures more than any tagline.
The CFO also knows the law already gives them tools: a fixed 40 EUR compensation per late invoice under the EU Late Payment Directive and statutory commercial interest (wettelijke handelsrente) of roughly 10 % a year in 2026. Your site has to explain what you add on top of their own reminders.
| CFO question | What the site must show | Recommended format |
|---|---|---|
| What does it cost? | Success fees of 8 to 15 % of amounts recovered, file fees of 25 to 90 EUR excl. VAT | Fee page + simulator |
| Is the agency compliant? | Wki registration, NVI or Keurmerk Incasso, liability insurance | Compliance block in the footer |
| What is the success rate? | Amicable recovery rate by bracket: under 90 days, 90 to 180 days, over 180 days | Simple chart |
| How do we send files? | Encrypted document upload, CSV invoice import | Client area |
| What are the timelines? | Reminder day 0, formal notice day 14, court route from day 45 | Timeline |
| What if amicable fails? | Partner bailiffs (gerechtsdeurwaarders), summary proceedings | Legal stage page |
| Is our data protected? | EU hosting, GDPR register, retention period | Security page |
The bad-debt cost simulator: the tool that triggers the call
The calculation that speaks to a CFO is simple: with a 5 % net margin, an unpaid 10,000 EUR invoice forces the company to generate 200,000 EUR of extra revenue to make up the loss. A four-field simulator (amount, age of debt, net margin, number of invoices) displays that figure, then your estimated fee and the likely timeline. At the end, a 'Request a mandate proposal' button captures a qualified lead with amount and sector. On this type of site, as a 2026 order of magnitude, a well-placed simulator generates 2 to 4 times more requests than a plain contact form.
| Kolonell tier | Budget | Main content | Timeline |
|---|---|---|---|
| Starter | 800,000 to 1,200,000 FCFA (1,220 to 1,830 EUR) | 8 to 10 pages, fee schedule, compliance block, mandate request form | 6 weeks |
| Growth | 1,200,000 to 2,000,000 FCFA (1,830 to 3,050 EUR) | Starter + bad-debt simulator, sector pages, legal blog, conversion tracking | 7 weeks |
| Premium | 2,000,000 to 3,500,000 FCFA (3,050 to 5,340 EUR) | Growth + encrypted claim upload with automatic receipt, animations, advanced SEO | 8 weeks |
| Real-time tracking extranet | Simple custom application, 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | Client dashboard, status per file, export | Quoted |
| Maintenance | 35,000 to 120,000 FCFA per month (53 to 183 EUR) | Updates, backups, security patches | Monthly |
For comparison, an Amsterdam agency in 2026 typically charges 8,000 to 25,000 EUR excl. VAT for an equivalent B2B site, as an order of magnitude. If you also serve Belgian or German creditors, site languages are set in the quote.
The pages that bring CFOs in from Google
Profitable searches are specific: 'incassobureau zakelijk Amsterdam', 'B2B debt collection Netherlands', 'collecting unpaid invoices from German customers'. Plan one page per sector where you have references (construction, logistics, wholesale, IT services) and one per procedure. Each page shows an anonymised case with figures, an average timeline and a call to action towards the simulator. One blog post a month on case law or payment terms keeps rankings moving, which can be supported by monthly SEO.

Sanne runs an 18-person collection agency in Amsterdam. She targets 6 new SME mandates a year through the website. An average mandate represents 40 files a year, with 3,500 EUR outstanding per file and a 65 % amicable recovery rate. Fees at 10 %: 40 × 3,500 × 0.65 × 0.10 = 9,100 EUR. File fees at 45 EUR: 40 × 45 = 1,800 EUR. Total: 10,900 EUR per mandate per year, or 65,400 EUR for 6 mandates. The Growth site costs at most 3,050 EUR and Standard maintenance 75,000 FCFA a month (114 EUR), so 1,368 EUR a year. The first signed mandate repays the first-year investment more than twice over.
FAQ
Should we publish our fee schedule online?
Yes, at least as a range: 8 to 15 % on success and 25 to 90 EUR per file. A CFO who finds no figures moves on to the next agency, and a range still leaves room for volume discounts.
Is online claim upload safe?
It is if files are encrypted, hosted in the EU and deleted after a defined period, for example 5 years after the file closes. The Premium tier includes encrypted upload with an automatic receipt.
How long until we show up on Google?
Allow 3 to 6 months for local searches such as 'incassobureau Amsterdam', longer for national terms. One article a month and sector pages speed things up.
Can the site connect to our collection software?
Yes, through a CSV export or an API if your software offers one. Full status synchronisation is a custom application, starting at 2,500,000 FCFA (3,810 EUR).
Which compliance details should be displayed?
Your Wki registration, liability insurer, the bank holding client funds and your GDPR policy. These four items fit into a 5-line block visible on every page.
