What’s the difference between a virtual finance team and an outsourced CFO?

A virtual finance team handles the day-to-day: bookkeeping, payroll, invoicing and monthly reports. An outsourced CFO works at a strategic level: forecasting, cash flow planning, KPIs and growth decisions. Many clients start with one and add the other later.
