Professional services (legal, accounting, consulting) M&A in the Benelux

Sector multiples

EV/EBITDA bands from the Upswitch Multiples Index (Q1 2026 snapshot), per country.

Deal dynamics in 2026

Professional-services M&A in the Benelux runs 3.8-5.7x EBITDA in Belgium, with the Netherlands ~0.4x higher driven by Amsterdam-anchored consulting demand. Two transfer mechanics dominate: partial partner buy-ins (incoming partners buying 5-20% from retiring partners over 3-5 years) account for ~60% of transitions; full firm acquisitions by larger consultancies or strategic mergers account for ~25%; pure family succession is rare (~5%) because the partner model rarely transfers along family lines. PE entered Benelux accounting and recruitment around 2022 (Bencis-style platforms) and has accelerated since: accounting roll-ups now drive 15-20% of mid-market transfers.

Valuation quirks specific to this sector

Three quirks dominate professional-services valuations. First: client portability. A consulting firm where the senior partner generates 40% of revenue through personal relationships faces 25-35% multiple compression unless a multi-year transition plan ties retention to that partner. Second: partner-compensation normalisation. Partners typically take below-market base salary plus profit share: for accurate EBITDA, the profit-share portion above market salary equivalent should normalise back into reported margin. Third: WIP and unbilled revenue. Engineering and consulting projects often run with significant unbilled WIP; buyers discount aggressively for old unbilled time (>120 days) as likely non-collectible.

Typical buyers

Three buyer archetypes acquire Benelux professional services in 2026: (1) Internal partner buy-ins: incoming junior partners buying out retiring seniors, typically at 4-5x EBITDA with multi-year payment structures; (2) Strategic consolidators in accounting and recruitment (PE-backed roll-ups like Crowe, Forvis, BDO-network practices) paying 5-6x on platform deals dropping to 4-4.5x on tuck-ins; (3) Strategic mergers among consultancies (peer firms combining) at 4-5x with significant non-cash structure (partner equity in the combined firm rather than full exit).

Frequently asked

How is a partner-led consulting firm valued differently from a corporate consultancy?

Partner-led firms typically clear 20-35% below comparable corporate consultancies because of personal-client-relationship risk. The premium can be recovered partially through earn-outs tied to client retention (3-5 years) and structured partner transitions, but the discount is hard to eliminate entirely for very personal-relationship-heavy practices.

What's a typical multi-year partner buy-in structure?

5-10% per year over 3-5 years is standard. Incoming partner pays via combination of cash + earn-out + bank financing, typically with valuation locked at year-1 multiple and adjustments capped at ±15% based on firm performance. Belgian VOF and Dutch maatschap structures require specific deed amendments per partner change.

How do I prepare WIP and unbilled time for due diligence?

Build an aging schedule by client and project: time logged, billed, and outstanding for collection. Provision aggressively for WIP older than 120 days unless there's active billing in progress. Buyers expect this schedule and provision; sellers who don't produce it face 5-15% multiple discount on unprovisioned aged WIP.
