Ideal for someone who:

• Has solid, hands-on bookkeeping experience
• Wants part-time work they can take full ownership of
• Works well independently and stays on top of the detail
• Understands field-based billing, not just office-based bookkeeping
• Knows their way around Xero and ApprovalMax. Beneficial if you have used Employment Hero systems too for Payroll.
• Isn’t afraid to follow up, ask questions, and keep things on track

• Your attention to detail and tenacity to investigate and resolve discrepancies drives you and motivates you.
• You are emotionally intelligent and understand how to build a positive work environment and foster collaboration.
• You are proactive, persistent, and focused on achieving results.
• You have a great memory for people and can develop relationships in person and remotely, while prioritising collaboration with internal stakeholders, providing guidance and training.
