SBI M 69 · M 70.2 · M 73
Law firms, notaries, accountants and bookkeeping firms, management consultants, advertising agencies and market researchers – for software vendors, office suppliers, training providers and service companies that want to reach offices in a region.
Our database holds 535,638 records (as of 4 November 2026); they are not yet assigned to an industry, so there are no counts of our own per industry yet. For your request we confirm the scope and data date in advance.
Export of the whole industry: €469 (final price). Selections by province, municipality or your own filters are quoted individually.
Official statistics: 267,710 businesses in the Netherlands according to CBS StatLine, table 81589NED “Bedrijven; bedrijfstak” (reference date 1 October 2026 (provisional), table updated 15 October 2026). SBI 69 legal and accounting services (60,860), 70.2 management consultancy (165,550) and 73 advertising and market research (41,300) combined; holding companies and head offices (70.10, 83,440) are not included. This is the size of the market, not the size of our database.
The industry brings together the office-based services of SBI section M: legal and accounting services (69), management consultancy (70.2) and advertising and market research (73). Holding companies and head offices (70.10) are not included; they are usually holding entities without customer-facing activity.
Management consultancy is the largest group with more than 150,000 businesses, many of them self-employed people without staff. If you are looking for firms with employees, choose a legal form (bv, partnership) or a website as a mandatory field. The legal form as a filter is only possible once the source provides that field; the current records have no legal form yet.

Public search tools exist for the regulated professions in this industry. They are meant to find or verify a firm, not to serve as an address list.
These 15 columns are included.
In this industry the difference between a firm and a one-person business is large. A bv or partnership with a website is usually a firm with staff; a sole trader in management consultancy is often a single consultant. For phone outreach this matters twice: you may call legal entities on business matters, sole traders only with their consent.
Lawyers and notaries are bound by professional secrecy and receive many requests. A postal campaign with a concrete offer often works better here than a cold calling round.
We sell time-tracking software and are looking for bookkeeping and accounting firms (SBI 69.2) in North Brabant and Gelderland, legal entities with a website only. How many records are there and what does the selection cost?

Questions
In the SBI, yes. Selection by SBI group 69.2 (accounting and bookkeeping) is possible once the source provides the SBI code; the current records have no SBI code yet. Whether a firm employs a chartered accountant is not in the export; the NBA register is the source for that.
Many independent consultants, coaches and interim managers register under SBI 70.22. CBS counts 154,920 businesses in this class (1 October 2026), the vast majority with one working person.
Only with prior consent or to an address the firm itself has published for such messages (Article 11.7 of the Dutch Telecommunications Act). This also applies to a bv or partnership. More in our guide to B2B outreach.
