Scab

What Scab does

Scab Accountants & Adviseurs B.V. is a Dutch private limited company headquartered in Tilburg that has provided professional services exclusively to the Dutch construction industry since its founding in 1973 as Stichting Scab beheer. The firm serves approximately 3,200–3,600 construction SMBs nationwide with a bundled offering spanning accountancy, tax advisory, payroll administration (CAO Bouw & Infra compliant), HR and labor law advisory, administrative services, and ESG/CSRD sustainability advisory — including a DuurzaamheidsDashboard for CO2 footprint and IF-rate benchmarking. Scab differentiates through sector specialization, an unusual no-partner-structure flat organization with no profit motive (reinvesting surpluses into client service), and membership in SRA, NBA, NIRPA, RB, AFM, and industry associations (Bouwend Nederland, NOA, BouwGarant).

The firm's technology layer centers on a proprietary HR and payroll platform called Personeel & Salaris (P&S), offered free to Scab payroll clients, with ESS/MSS/HRSS self-service portals, pro forma module, documentgenerator (with ValidSign e-signature), and one-click integrations to construction-specific ERP systems (BouwWorks, Kraan, Exact Bouw7, Robaws/Probouws, Vakware, Navision 4ps, BouwOffice/InfraOffice/InstallOffice via BouwInfosys). Complementary tools include the Power BI-based Scab Dashboard for management information, Twinfield-based Online Boekhouden, Basecone scan-and-recognize for invoice processing, and the DuurzaamheidsDashboard for ESG reporting. The Premiumpakket subscription (from 51 employees) layers dedicated advisor hours, pro forma calculations, severance computation, and CBA-compliant document generation on top of base payroll services.

Scab operates a sales-led, direct-delivery GTM with nationwide coverage through six dedicated client teams (Klantteam 1–6) and a commercial manager, supported by an in-house Academy that runs paid training sessions for both clients and non-clients. Revenue is generated primarily through retainer-like professional services engagements, supplemented by subscription income (Premiumpakket), training/academy fees, and Detachering (temporary staffing of financial/administrative specialists at client sites). The firm holds an AFM-vergunning enabling statutory audit work, NIRPA certification for payroll competency, and MVO (CSR) and SDG-related recognitions, and competes as the largest payroll administrator in the Dutch construction sector.

Core offering

Scab is a Netherlands-based accounting and advisory firm exclusively serving construction companies, delivering a full-stack service portfolio spanning accountancy, tax advisory, payroll administration, HR and labor law advisory, administrative outsourcing, and ESG/sustainability reporting. The firm bundles these services through dedicated client teams and supplements them with proprietary HR/payroll software (Personeel & Salaris), a Power BI-based management dashboard, sector-specific training through Scab Academy, and temporary specialist secondment.

Product overview

Scab is a construction-sector accountancy and advisory firm operating as a unified service portfolio rather than a modular software platform. Its offering spans six core service lines — Accountancy, Fiscaal advies (Tax Advisory), Loonadministratie (Payroll Administration), HR- en arbeidsjuridisch advies (HR and Labor Law), Administratieve dienstverlening (Administrative Services), and Duurzaam Ondernemen (ESG/Sustainability) — supplemented by several proprietary digital tools and add-on modules. Key products include Personeel & Salaris (P&S), a free HR and payroll software built specifically for the construction sector, which integrates with major ERP systems (BouwWorks, Kraan, Exact voor de bouw, RobAWS/Probouws, VakWare, Navision 4ps) and powers self-service portals (ESS/MSS/HRSS), automated workflows, benchmarking, and a pro forma module. The Scab Dashboard (management information, Power BI-based) and Online Boekhouden via Twinfield round out the technology layer. The Premiumpakket adds dedicated advisor hours, a documentgenerator, and ValidSign digital signing. Scab Academy delivers sector-specific training courses, and Detachering provides temporary specialist staffing. The DuurzaamheidsDashboard enables ESG data monitoring and benchmarking. The portfolio is delivered through specialized client teams organized by construction sub-sector.

Others

• Bouwend Nederland: Largest Dutch construction and infrastructure employers' association (~4,300 member companies, ~9% of Dutch GDP). Strategic partner/ecosystem participant for Scab, not a direct competitor, but the dominant industry voice that shapes Scab's market.
• Exact (Software): Dutch SMB ERP/accounting software vendor whose Exact voor de Bouw (Bouw7) is integrated into Scab's P&S platform. Adjacent ecosystem participant in construction financial administration, with potential to compete for the underlying management-information workflow.
• AFAS Software: Dutch HR, payroll and ERP software vendor whose Profit & Payroll platform is already used by Scab for payroll processing. Adjacent ecosystem participant - a potential partner or alternative delivery channel for Dutch construction payroll.

Direct peers

• Van Oers Accountancy & Advies: Dutch accounting and advisory firm serving MKB companies in West-Brabant and wider Netherlands with accountancy, tax, HR and payroll services. Comparable to Scab on bundle, target segment, SRA membership and regional delivery.
• Flynth: Dutch SRA-affiliated accounting and advisory firm focused on agriculture, SME and MKB clients with bundled accountancy, tax, payroll and HR services. Same professional-services bundle and SMB go-to-market as Scab, though in a different primary vertical.
• Countus: Dutch accounting and advisory firm specializing in agriculture, horticulture and MKB - closely mirrors Scab's vertical-specialist model for a different sector, making it a strong structural parallel even outside construction.
• Baker Tilly Netherlands: Dutch mid-market accounting and advisory firm serving MKB companies including construction. Closely comparable to Scab in service mix (accountancy, tax, payroll, advisory), target segment and pricing model.

Broad incumbents

• BDO Netherlands: Major Dutch accounting and advisory network active in the construction sector. Comparable to Scab on accountancy, tax and payroll services for MKB, but operates broadly across industries and internationally.
• Mazars Netherlands: Mid-tier international accounting and advisory firm serving Dutch MKB and construction-sector clients. Overlaps with Scab on outsourced accountancy, tax, payroll and HR advisory, but with a much wider sector and geographic footprint.

Emerging players

• Visma | Nmbrs: Cloud-native Dutch HR and payroll SaaS increasingly used by MKB employers as a direct alternative to accountant-managed payroll. Threatens the payroll-admin baseline of firms like Scab through productized, self-serve automation.
