What Kros does

KROS a. s. is a Slovak software company founded in 1995 in Žilina that develops business software exclusively for the Slovak market, serving approximately 140,000 users across four primary customer groups: small business owners and sole traders (Malý podnikateľ), growing firms (Firma), accounting offices (Účtovná firma), and construction and real estate professionals (Stavebníctvo). The company operates as a hybrid desktop-and-cloud platform with 21 products covering accounting, payroll, invoicing, tax compliance, document digitization, ERP, and construction cost estimation — all aligned with Slovak legislative and tax requirements — and is headquartered in Žilina with approximately 280 employees.

The product portfolio is split between desktop applications — ALFA plus (single-entry bookkeeping), OLYMP (payroll and HR), OMEGA (double-entry bookkeeping), ONIX (ERP), CENKROS 4 (construction budgeting), HYPO (real estate valuation), and MEMO (expert journal) — and a parallel suite of online SaaS applications for invoicing, digital document management, tax returns, personnel records, attendance tracking, construction progress, and quantity takeoffs from 2D drawings and BIM. The proprietary CENEKON price database, containing over one million items from manufacturers and suppliers, is recognized in Slovak public procurement and integrated across the construction product line. Technical interoperability is enabled through the ISDOC electronic document exchange standard, the ONIX Web API, and configurable webhooks for third-party system connectivity.

Revenue is generated primarily through recurring software subscriptions priced in EUR — annual desktop licenses and monthly or annual SaaS bundles ranging from roughly EUR 10 to EUR 120 per month depending on tier — supplemented by professional services at EUR 69–79/hour, flat-fee ONIX preventive maintenance at EUR 2,190, paid training through KROS Akadémia (EUR 329–590 per course), and a partner application ecosystem including Raynet CRM, FiskalPRO, and Shoptet/WooCommerce connectors. Distribution combines self-serve e-commerce at eshop.kros.sk, a telephone-based inside sales motion staffed by 60 consultants handling roughly 70,000 calls per month, free-trial downloads (1-month for ALFA plus, 7-day for construction suites), and content-led acquisition through KROS Akadémia. The company has no disclosed external funding, no M&A activity, and operates only within Slovakia.

Expansion highlights6 records

Direct peers

• Stormware (POHODA): Czech-headquartered accounting and ERP software vendor whose flagship POHODA product competes directly with ALFA plus and OMEGA in the SMB accounting/payroll segment. Operates in the closely adjacent Czech market with comparable legislation-driven localization.
• Money S3: Slovak accounting and ERP software vendor serving SMBs and accounting firms with a product portfolio comparable to KROS's ALFA plus, OMEGA, and ONIX. Direct domestic rival with overlapping customer segments.
• MRP (Slovak ERP): Slovak ERP and accounting software vendor targeting SMBs and mid-market firms with production, warehouse, and accounting modules — overlapping with KROS's ONIX ERP and OMEGA accounting offerings.
• Solitea: CEE-focused business software group (formerly Vema, Altus, Seyfor-adjacent brands) offering accounting, payroll, ERP, and HR solutions in Slovakia and the Czech Republic, competing with KROS's OLYMP, OMEGA, and ONIX.
• Seyfor: Central European ERP, accounting, and HR software provider operating across Slovakia, Czechia, and adjacent CEE markets. Comparable in product scope (accounting + payroll + ERP) and customer size (SMB and mid-market).
• Altus Vario: Slovak accounting and business software vendor serving small firms and accounting offices. Competes with ALFA plus and OMEGA for the same Slovak accounting-firm and SMB customer base.
• Money S3 (Jet's Software): Already-listed as direct peer — included separately to flag the close overlap with KROS's Slovak SMB accounting segment. Listed again only as a regional peer reference point.

Broad incumbents

• SAP Business One: Global ERP incumbent whose mid-market Business One line competes with KROS's ONIX for larger Slovak SMBs and mid-market accounts. Overlaps in core functionality (accounting, inventory, reporting) but operates across industries and geographies.
• Microsoft Dynamics 365 Business Central: Global mid-market ERP and business management suite that competes with ONIX and OMEGA for growing Slovak firms. Wider portfolio than KROS but increasingly targeted at the same SMB and accountant channel.

Emerging players

• Xero: Cloud-native global SMB accounting platform gradually localizing into CEE markets. Not yet a direct daily competitor to ALFA plus, but represents the cloud-first architectural threat to KROS's desktop-heavy portfolio as Slovak founders adopt cloud tools.
