Bookkeeping
Our bookkeeping services ensure accurate financial record-keeping using modern cloud-based technology. We manage daily transactions, maintain ledgers, and prepare financial statements to give businesses clear oversight. With over 30 years' local experience, we optimise processes to save time while maintaining compliance with regulatory requirements.
Payroll Services
Comprehensive payroll solutions handle all aspects of employee payments and compliance. We process timesheets, manage leave accruals, generate payslips, and ensure superannuation lodgements meet statutory requirements. Our service reduces administrative burdens while maintaining accuracy in award interpretations and employee payment schedules.
GST & PAYG Tax
Expert management of GST and PAYG obligations ensures businesses meet tax requirements. We prepare and submit BAS statements, handle quarterly reporting, and liaise with the ATO on your behalf. This service minimises compliance risks while allowing business owners to focus on core operations without tax-related concerns.
Accounts Payable
Efficient accounts payable management streamlines invoice processing and payment scheduling. We capture invoices accurately, obtain authorisations, and maintain budget visibility to improve supplier relationships. This service helps businesses manage cashflow effectively while taking advantage of early payment discounts where available.
Management Reporting
Customised management reports provide strategic financial insights through variances, KPIs, and budget comparisons. Available weekly, monthly or quarterly, these reports help business owners make informed decisions. We present complex financial data in easily understood formats to support long-term business growth and development.

I can't recommend Cath from Add N Sum highly enough. I recently requested her services to assist me with a rather difficult situation, her professionalism is of a high level but she also cares about her clients and doesn't make you feel like just another number. Thanks again Cath and I look forward to working with you again soon.
