Our Virtual CFO gave us a 13-week cash flow forecast that completely changed how we manage the business. We now know our cash position weeks ahead and can make payment and investment decisions with much more confidence.
Meridian Foods, Kochi, India
We had an accountant, but we didn’t really have financial management. BI-Outsource stepped in as our Virtual CFO, bringing together reporting, cash-flow planning, budgets and management insights. For the first time, our monthly numbers actually help us make decisions.
Nexora Technologies, Bengaluru, India
We already had an accounting team, but needed senior financial oversight. BI-Outsource’s Virtual CFO helped us turn our accounting data into management information — with cash-flow forecasting, budgeting and clear KPIs for the leadership team.
Summit Growth Partners, Austin, Texas, USA
