What RZA does

RZA GmbH is an Austrian IT systems house founded in 1982 and headquartered in Gmünd (Lower Austria, Waldviertel region), operating as a private limited company with 11–50 employees. The company delivers an integrated business software suite — worxx by rza® (accounting and invoicing), lohn by rza® (payroll), fakt by rza® (inventory and ERP), kassa by rza® (RKSV-compliant cash register), and maxx by rza® (document management) — alongside IT infrastructure services including hardware procurement, server and network solutions, Microsoft 365 integration, cloud backup, and IT monitoring/outsourcing. The software is developed domestically ("Made in Austria") and is certified against Austrian statutory interfaces including FinanzOnline (BMF webservice for UVA/ZM submissions), ELDA (social security data exchange), A-Trust (RKSV signature certificates), and PSD2-compliant bank connectivity via finAPI.

The company's go-to-market is relationship-led and domestically focused: free trials (kostenlos testen), free consultation appointments (both online and in-person), regional Meet Up events across Austrian provinces, a recurring webinar series, and a tax-advisor (Steuerberater) referral channel. Revenue is generated through three streams — recurring software licenses/subscriptions with maintenance agreements, hardware sales, and IT consulting/support services — under quote-based pricing with no public list. Customer segments are primarily small businesses, sole proprietors (EPU), and small-to-medium enterprises (KMU) across Austria, supplemented by tax advisors, vertical-specific users (retail, gastronomy, construction, associations, funeral services, crafts), and IT infrastructure customers. RZA states it serves "several thousand" customers nationally, with logo references including the Austrian Parliament and BZ Bau.

RZA combines a vertical software vendor and a regional IT systems house into a single bundled offering, which differentiates it from pure-play SaaS competitors and global accounting platforms by bundling localized statutory compliance, personal on-site support, and IT infrastructure provisioning under one contract. Recent strategic activity has centered on incremental product releases (EFZG in lohn, Digitaler Beleg in kassa, worxx update notifications across 2026), deepening the Microsoft and finAPI partnerships, and expanded regional event marketing — with no M&A, no external funding rounds, and no public ownership transactions on record.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• DATEV: DATEV is the dominant German cooperative software provider for tax advisors and SMBs, with deep statutory and tax-compliance integrations analogous to RZA's Austrian regulatory moat. It is a broader incumbent in the same product category.
• Microsoft Dynamics 365 Business Central: Dynamics 365 Business Central is Microsoft's cloud ERP/accounting platform with growing SMB adoption in DACH, often deployed via Microsoft 365 channels that RZA also leverages. It is a broader incumbent competing for the same mid-market and growth-stage SMB buyers RZA serves.
• Sage: Sage is a global incumbent in SMB accounting, payroll, and ERP software with regional DACH offerings. It overlaps with RZA across the core accounting/payroll categories and represents a scaled, internationally funded competitor in the broader SMB software market.
• lexoffice (Haufe Group): lexoffice is a leading German cloud accounting and invoicing SaaS for SMBs, part of the Haufe Group. It competes broadly with RZA's worxx/fakt product line in the DACH SMB market and represents the cloud-native benchmark RZA must match.
• Lexware (Haufe Group): Lexware is a long-established German SMB software suite covering accounting, payroll, invoicing, and ERP. It is comparable to RZA's product portfolio in scope and SMB target market, though operating at significantly larger scale in Germany.

Emerging players

• sevDesk: sevDesk is an Austria/Germany-rooted cloud accounting and invoicing platform targeting freelancers and small businesses. It competes for the same EPU/SMB customer segment as RZA but with a cloud-native, mobile-first UX that pressures on-premise incumbents.
• Run my Accounts: Run my Accounts is an Austrian/Swiss cloud-based bookkeeping and accounting service targeting SMBs. It overlaps with RZA's accounting and payroll offerings and competes in the same Austrian SMB market with a more modern, service-inclusive model.

Direct peers

• RZL Software: RZL is a major Austrian accounting software platform widely used by tax advisors and SMBs, with overlapping coverage of Buchhaltung, Lohnverrechnung, and Fakturierung. RZA itself integrates with RZL for data export, confirming direct functional overlap.
• Agenda (Agenda Software): Agenda is an Austrian SMB-focused business software suite covering accounting, payroll, and invoicing for EPU and KMU. It is a direct competitor to RZA's worxx/lohn/fakt bundle with similar Austrian-regulatory positioning and SMB target segment.
• BMD Systemhaus: BMD is one of Austria's largest accounting and payroll software providers, serving both SMBs and accounting firms with integrated ERP, payroll, and tax-compliance modules. It is the dominant incumbent competitor in the Austrian Steuerberater channel that RZA also targets.
