Our Core Offerings
Financial Accounting
Accurate monthly Profit & Loss, Balance Sheet and Cash Flow reporting, prepared in Xero and reconciled to the cent. You always have a clear, current picture of your financial position, ready for review whenever you need it.
Budgeting & Forecasting
Realistic budgets and rolling forecasts built from your actual trading history, not guesswork. We help you plan cash flow, test different scenarios and make decisions with confidence, grounded in real, up-to-date numbers.
Management Reporting
Clear, board-ready reports designed for the people who rely on them: owners, trustees and committees. We translate the numbers into plain-English commentary, so meetings focus on decisions rather than deciphering spreadsheets.
Contract Accounting
Short-term, flexible cover that keeps your accounts running smoothly while your in-house team is on leave, recruiting, or navigating a transition. We step in quickly, learn your systems and keep reporting on schedule.
Hubdoc Bill Automation
Bills and receipts captured and coded into Xero automatically, managed end-to-end by a certified Hubdoc specialist. Less manual data entry means fewer errors, faster reconciliations and records you can trust all year round.
Custom Financial Reporting
Purpose-built reports and visual dashboards that turn raw Xero data into clear, decision-ready insight. We tailor every report to the KPIs your organisation actually tracks, presented the way you want to see them.
Three-Statement Financial Modelling
Fully integrated Profit and Loss, Balance Sheet and Cash Flow forecasts over five or ten years, built to your requirements. Ideal for strategic planning, funding applications, capital projects and board decision-making.

Frequently Asked Questions
We provide financial accounting (monthly Profit & Loss, Balance Sheet and Cash Flow reporting), budgeting and forecasting, management reporting for owners and directors, contract accounting cover, Hubdoc bill automation, custom financial reporting and dashboards, and three-statement financial modelling for funding or strategic planning — all built in Xero and delivered online, wherever you’re based in New Zealand.
Every package is fixed-price and built around what your business actually needs, rather than a one-size-fits-all plan — so you’ll always know your fee upfront with no surprise bills. Because pricing depends on the size and complexity of your business, the best way to get an accurate quote is a free consultation.
No. If you’re not on Xero yet, we can set you up and migrate your existing records across; if you’re already using Xero, we simply pick up from where you are. Either way, you’ll end up with a system that’s properly configured and easy to keep on top of.
Not at all — everything is delivered online, so we work with small businesses anywhere in New Zealand. Being Kerikeri-based doesn’t limit who we can support.
Bookkeeping is the day-to-day recording and reconciling of transactions in Xero — the groundwork that keeps your numbers accurate. Management reporting takes that data and turns it into clear, plain-English reports that owners and directors can actually use to make decisions, rather than a spreadsheet you have to decode yourself.
Request a free consultation using the form on this page or by emailing mathew@mundax.com. We’ll talk through your current setup and what you need, then put together a fixed-price package before any work begins.
