What SYSTEMS MODELLING LIMITED does
Systems Modelling Limited is an Irish private consultancy founded in 1997 and headquartered in Gorey, Co. Wexford, that specialises in Excel and VBA spreadsheet development, auditing, quality testing, and controls. The firm operates as a boutique practice led by principal consultant Patrick O'Beirne and serves finance, accounting, and internal audit professionals whose organisations rely on spreadsheet-based information systems subject to regulatory scrutiny such as Sarbanes-Oxley. Core offerings include the XLTest spreadsheet auditing add-in for Excel 2010-2016 (providing colour maps, version comparison, and test case execution for compliance), the SCANXLS utility for spreadsheet inventory and risk assessment, the EuroCalc online currency converter, training courses in spreadsheet best practice and auditing, and bespoke consultancy in model review, re-engineering, and quality testing. The business also publishes the reference book 'Spreadsheet Check and Control: 47 key practices to detect and prevent errors' (September 2005) via Amazon storefronts across North America, Europe, and Japan, and through a direct online shop.
The firm's revenue model is a mix of one-time software licences for XLTest, one-time book sales at €29.95-€39.95 per copy, and quote-based professional services for training and consulting engagements. Go-to-market is largely product-led and reputation-led: the XLTest add-in, book, free resources on sysmod.com, and O'Beirne's published papers and EuSpRIG conference presentations act as top-of-funnel credibility builders, with bespoke training and consulting closing enterprise and SMB engagements directly. The firm is bootstrapped with no external funding, no parent company, and no disclosed institutional investors; headcount is reported at 1-10 employees. Customer segments are horizontal rather than vertical, addressing end-user spreadsheet developers, finance and accounting professionals, and internal/IT auditors across geographies served primarily through digital channels.

SYSTEMS MODELLING LIMITED competitors and assessment
Company assessmentBroad incumbents
- ClusterSeven (insightsoftware): Enterprise spreadsheet risk management and intelligence platform sold to large regulated firms for SOX-grade controls. Direct functional competitor to XLTest but at a much larger, enterprise-platform scale.
- Protiviti: Global consulting firm with a dedicated risk and compliance practice that regularly delivers spreadsheet controls, SOX 404 and model audit engagements. Competes for the same enterprise advisory work Systems Modelling targets.
- Resolver: Enterprise risk and compliance software platform covering audit, risk and controls — overlapping with Systems Modelling's spreadsheet-controls/compliance value proposition for finance and audit teams.
- Acuity Risk Management: STREAM risk management software used for risk assessment and regulatory compliance workflows, comparable to Systems Modelling's controls and audit use cases but at enterprise scale.
Direct peers
- ExcelJet: Online Excel training and best-practices resource serving finance and analyst professionals. Comparable to Systems Modelling's training and consultancy arm in audience and content positioning.
- Ablebits: Maker of Excel add-ins and utilities for productivity and data quality, comparable to Systems Modelling as a third-party Excel add-in developer targeting professional spreadsheet users.
- ASAP Utilities: Long-running Excel add-in providing auditing, cleaning and quality tools for power users; functionally adjacent to XLTest's spreadsheet integrity focus and same target audience.
- Validatar: Provides automated spreadsheet testing, validation and audit tools targeted at the same compliance and risk audiences as Systems Modelling. Closest direct product overlap in the spreadsheet audit niche.
Others
- Spreadsheet Risk Analysis (Ray Panko) / EuSpRIG community: Academic and practitioner community for spreadsheet risk research, including Ray Panko's foundational error-rate work. Not a competitor but the canonical ecosystem in which Systems Modelling operates and sources authority.
Emerging players
- Solver: Cloud-based financial planning and reporting platform that competes with spreadsheet-centric workflows in finance teams. Adjacent threat to Systems Modelling's installed base of spreadsheet models.
