What is outsourced accounting and how does it work?
Outsourced accounting means a dedicated accountant, bookkeeper or finance team works for your business full time from ATO’s managed offices instead of your payroll. You direct their daily work; ATO handles recruitment, office space, equipment, HR, payroll and retention for one transparent monthly fee.
