“Oyonnx helped us clean up our tax, negotiate IRD penalties, and get fully compliant. Since working with them, our revenue has grown by 26%, costs have dropped by 6%, and we've turned losses into profit, with $298,000 in penalties written off. The turnaround has been incredible.”
Common questions
We reconcile your bank accounts, keep your records straight, prepare management reports you can make decisions from, watch your cash flow, and file your GST, PAYE and income tax returns. Businesses in Hamilton, Tauranga and Auckland get the same service from the same team.
Yes. We process wages and salaries, file PAYE, issue payslips and keep the compliance records, so payroll stops being a Sunday-night job for the owner.
That is common and it is fixable. We get your records current, file what is outstanding, and negotiate with IRD on your behalf. One civil contracting client we worked with had $298,000 in penalties written off and moved from a loss to a profit.
No. We meet at our Hamilton, Tauranga or Auckland office, on your site, or online — whichever suits how you work.
