Buying B2B leads in the Netherlands: four things sold as leads, and what each costs
Tips
The short answer
"Buying leads" covers four different things in the Netherlands, and they differ by a factor of a thousand in price. An address file costs a few cents per row. Contact details cost a few euros per person. A qualified lead from an agency costs 50 to 500 euros. A booked appointment costs 150 to 750 euros. What you do not buy in any of the four cases is permission to contact those people: the list does not decide who you may approach, the law does. This page puts the four side by side, with what they cost, what drives the price and what you may do with them. For the specific case of a file of company addresses from the Dutch Business Register, see buying a Dutch business address list.
Four things called "leads"
What you buy | What you get | What it costs | Where it goes wrong |
|---|---|---|---|
An address file | Company data from the Business Register: name, address, activity code, size. No people | A few cents per row | No contact persons, no mobile numbers, and it starts decaying on day one |
Contact details per lead | Name, role, business email, sometimes a mobile number | A few euros per contact, usually through credits | You pay per record, not per usable record; verification rates vary widely |
A qualified lead | A company the agency says showed interest | 50 to 500 euros per lead | "Qualified" means something different at every vendor; get the definition in writing |
A booked appointment | A meeting in your rep's diary | 150 to 750 euros per appointment | No-shows and meetings with the wrong job title often still count |
Per-lead and per-appointment prices: Searchlab, published 17 March 2026 (Searchlab). The range from 25 euros for simple leads to 500 euros and up for decision-maker contacts comes from Leadworks, a Dutch lead generation agency (Leadworks, undated, retrieved 22 September 2026). Both are parties that sell leads themselves, so read these as market prices rather than independent research.
What drives the price per lead
The channel. The spread is wider than most buyers expect. Searchlab gives 15 to 80 euros per lead for cold email, 20 to 80 for SEO and content, 30 to 120 for organic LinkedIn, 40 to 250 for Google Ads, 75 to 350 for LinkedIn Ads and 80 to 400 for telemarketing. Leadworks lands on similar orders of magnitude: 30 to 80 for content, 75 to 150 for LinkedIn, 100 to 300 for telemarketing and 150 to 400 for events and webinars.
The seniority of the contact. A lead at a team leader is cheaper than a lead at board level, and that difference explains most of the spread within a single sector.
Exclusive or shared. A shared lead is sold to several buyers. It is the cheapest form and also the form where your competitors call the same person on the same day. Always ask whether the lead is exclusive, and for how long.
The definition of "lead". This is the most important and the least discussed. Is it a company that filled in a form, a company that downloaded a whitepaper, or a company that had a conversation about your offer? Put the definition in the contract, with the criteria on which you may reject a lead.
The agency itself. Searchlab gives monthly retainers of 750 to 2,500 euros for a freelance specialist, 2,000 to 5,000 for an SME-focused agency and 3,000 to 10,000 for a full-service agency, excluding advertising budget.
What you may and may not do with them
This is the part that rarely comes up at the point of purchase, and where the Dutch rules are stricter than buyers expect.
The Non-Mailing Indicator. Companies can record with the Dutch chamber of commerce that their address must not be used for advertising post or door-to-door sales. The indicator appears on that company's extract. Note what it does not do: the chamber treats unwanted email and calls as separate matters with their own measures, so the indicator is not an email or phone opt-out (KVK, retrieved 22 September 2026).
The information duty in article 14 GDPR. If you buy personal data you did not collect from the person, you have to tell them: who you are, what you use the data for, on what legal basis, and where you got it. That has to happen within a reasonable period and at the latest within one month, or at first contact if that comes sooner. In practice it means your first email or call carries that information or points to it.
Calling. A commercial call to a sole trader or partnership has needed prior consent since 1 July 2021, and since 1 July 2026 that includes existing customers. An incorporated company such as a BV falls outside it.
Emailing. Cold emailing a company in the Netherlands generally is not possible without consent. What applies per channel, per country and per legal form is in is B2B cold outreach legal in Europe?
One thing follows from all this that is worth remembering: you buy data, not a legal basis. A vendor who says their list is "GDPR compliant" is saying something about their own processing, not about yours.
How fast it decays
A bought list is a photograph, and Dutch and Belgian company data moves faster than most buyers assume: addresses, directors, legal status and headcount all change every year. How fast exactly is in how fast Belgian B2B data goes stale, and what a bought address file does and does not contain is in buying a Dutch business address list.
With leads bought individually the decay sits somewhere else: not in the record, but in the moment. A lead that showed interest three weeks ago and is only followed up now is no longer a warm lead. So with pay-per-lead, do not only ask what a lead is, but also how old it is when it reaches you.
When buying does make sense
Buying works when you have a bounded, one-off question: a campaign in one region, a test in a new sector, an event you want to invite a hundred companies to. Then a file or a package of leads is faster than building it yourself, and decay has no time to set in.
Prefer to pay an agency to do the work rather than buy data? What outsourcing costs and the five questions to ask first are in outsourcing lead generation in the Netherlands. For everything else, building the list yourself is the better route. The five steps are in how to build a B2B lead list.
It does not work when you need new companies every month. Then you buy the same photograph again each month, pay twice for companies you already had in your CRM, and still have no answer to the question of who to call this week. At that point a flow is more useful than a list: companies that match your profile and are doing something right now that you can act on. That is what Bizzy's AI lead generation agent does, built on Belgian register data and Creditsafe data for other European countries, the Netherlands included, with signals such as vacancies and management changes. What to do with such a company next is in B2B cold calling in Europe and B2B cold email in the Benelux.
Bought leads are two of seven sources; the other five, and how they compare on warmth and cost, are in B2B leads in the Netherlands.
Frequently asked questions
What does it cost to buy B2B leads in the Netherlands? It depends on what you buy. An address file costs a few cents per row, contact details a few euros per contact, a qualified lead 50 to 500 euros and a booked appointment 150 to 750 euros. The channel and the seniority of the contact explain most of the difference.
Is it legal to buy leads? Buying data is allowed. What you may do with it is a separate question: you have to inform the people on the list under article 14 GDPR, respect the Non-Mailing Indicator for post, and follow the Dutch rules for calling and emailing, including the consent requirement for commercial calls to sole traders and partnerships, which since 1 July 2026 also covers existing customers.
What is the difference between a lead and an address file? An address file is company data without people and without interest. A lead is a company or a person the seller says has shown interest. You pay per row for the first and per item for the second, and the price difference is usually a factor of a hundred or more.
Are bought leads exclusive? Not automatically. Shared leads are sold to several buyers, which is why they are cheaper. Ask before you sign whether leads are exclusive, and if so for how long.
What should I ask a lead vendor before buying? Four things: the definition of a lead and the rejection criteria, the age of a lead at the moment of delivery, whether it is exclusive, and where the data comes from. That last one decides whether you can show provenance if anyone asks.
