SD Worx

What SD Worx does

SD Worx is a Belgian-headquartered HR and payroll solutions provider founded in 1945 and headquartered in Antwerp, operating under the legal name SD Worx People Solutions NV. The company serves more than 95,000 organizations across 27 European countries and processes payroll for approximately 6 million employees, placing it among the global top five HR and payroll providers. It maintains 19 distinct payroll engines — one per country or market — to handle local labour-law and tax compliance, and operates an "airport model" that balances central strategic direction with local autonomy across markets.

The platform is cloud-based SaaS covering the full HR lifecycle: core payroll (for SMEs, large enterprises, and multinationals), workforce management and time & attendance, HR analytics, an HCM tool, the mysdworx employee self-service portal and mobile app (iOS/Android), reward and compensation management, HR legal and fiscal consulting, SAP SuccessFactors implementation and add-ons, and the SD Worx Compass talent management platform. Customers include SMEs, large organizations, multinationals, and accountants and bookkeepers, served through a combination of field sales, inside sales, self-serve digital channels, 33 Belgian branch offices, and dedicated staffing brands (SD Worx Jobs, SD Worx Professionals, Protime). The company holds ISO 27001, ISO 27701, ISAE 3402 Type II, and ISAE 3000 certifications, and is recognized by Gartner, NelsonHall, and Everest Group.

Revenue is generated primarily through subscription-based SaaS contracts (annual billing) bundled with professional services — payroll processing fees, HR consulting, legal and fiscal advisory, training via SD Worx Academy, and staffing/interim services. FY 2025 consolidated revenue was €1.307 billion (+10.7% YoY), with adjusted EBITDA of €271.2 million (+16.5%) and net profit of €101.4 million, the first time the company crossed €100 million in net profit. Growth has been driven principally by M&A: at least eight acquisitions since 2021 across the Nordics (Aditro), Ireland (Intelligo), Central and Eastern Europe (Romanian Software), Italy (F2A, Codeas, HR Service), and France (Socialea, Paie & RH Solutions). The company is privately held with no disclosed parent, PE, or VC backing, and is led by CEO Kobe Verdonck.

Direct peers

• Zalaris: Nordic-headquartered provider of HR and payroll outsourcing services with pan-European operations. Closely comparable to SD Worx in multi-country payroll managed services and is among the most direct European-headquartered competitors on cross-border payroll.
• Sage Group: UK-headquartered SMB accounting and payroll/HCM vendor with established presence across continental Europe (Sage HR, Sage Business Cloud Payroll). Directly comparable on SME payroll SaaS and overlapping customer segments with SD Worx's KMO franchise.
• ADP (Automatic Data Processing): The world's largest payroll and HR services provider with broad multi-country capabilities (including ADP Streamline for international payroll). Highly comparable as a full-service, multi-country payroll and HCM outsourcer competing for the same large-enterprise and international customer cohorts as SD Worx.
• Dayforce (formerly Ceridian): Global HCM and payroll SaaS provider with strong North American and growing European presence (UK, Ireland). Closely comparable as a mid-to-large enterprise HCM-plus-payroll SaaS platform with managed services; recently taken private, indicating market expectations for the segment.
• UKG (Ultimate Kronos Group): HCM, workforce management, and payroll provider formed from the merger of Ultimate Software and Kronos. Overlaps with SD Worx across workforce management, time and attendance, and payroll SaaS for mid-market and enterprise customers in North America and Europe.
• Paychex: Leading SMB-focused payroll and HCM provider in the US with a recurring SaaS-plus-services model. Comparable business model to SD Worx's SME payroll and outsourcing offerings, although primarily serving US SMBs.
• Alight Solutions (formerly NGA Human Resources / The Resource Group): Cloud-based HCM and payroll services platform with a deep European delivery footprint (UK, Germany, France, Netherlands). One of the closest direct competitors to SD Worx in managed multi-country payroll and HR outsourcing for large multinationals.

Emerging players

• Deel: AI-forward, multi-country payroll, EOR, and contractor payments platform rapidly scaling across Europe. Competes most directly with SD Worx's international payroll proposition for SMEs and tech-forward employers, though primarily via a software-led rather than services-led model.

Broad incumbents

• Workday: Enterprise cloud HCM, payroll, and financial management leader increasingly extending into Europe. Overlaps with SD Worx at the high end of the market, but Workday operates a broader enterprise platform rather than SD Worx's localized payroll-and-services model.
• SAP SuccessFactors: Enterprise HCM suite within SAP's portfolio, including Employee Central Payroll. Both a strategic partner of SD Worx (for managed payroll, add-ons, and cloud migration) and an indirect competitor as SAP extends native payroll coverage across more European jurisdictions.
