ONISIS Consulting is a boutique financial-management advisory firm helping growing SMEs (€3M–€50M turnover) identify where money is lost, where capital is trapped, and which strategic decisions to make first.
Founded by Konstantinos Kormentzas, a former C-level banking executive (CRO/Auditor/COO), ONISIS acts as an objective, un-fogged "second brain" for business owners. We combine executive banking rigor with practical operational execution, replacing generic consulting reports with clear, empirical numbers.
Our Core Practice Areas:
• Fractional CFO Advisory: Senior-level financial leadership, governance, and objective sounding-board advisory for founders without the overhead of a full-time C-suite executive.
• Cash Flow & Working Capital Optimization: Freeing up trapped liquidity across receivables and inventory to self-fund expansion and eliminate reliance on emergency debt.
• Profitability Enhancement: Granular customer- and SKU-level margin analysis to pinpoint hidden profit leaks and optimize discount and pricing structures.
• Business Intelligence & Executive Reporting: Custom decision-support architectures (Power BI) that create a single source of truth across sales, operations, and cash flow.
• Strategic Financial Planning & Financing: Bank-grade business plans, scenario forecasting, and capital structure advisory to secure funding on optimal terms.
Who We Work With:
We specialize in owner-managed enterprises (€3M–€50M turnover) primarily across manufacturing, wholesale trade, distribution, and commercial services.
Our work begins with a focused, confidential diagnostic sprint that delivers immediate zero-CapEx clarity, followed by flexible operational oversight retainers.
Headquartered in Athens, Greece (Michalakopoulou 35). Learn more at https://onisisconsulting.gr.
