How I can Help
If you're just starting out, or you've been struggling with your bookkeeping for a while, I can help take the pressure off.
If you're just starting your business journey, everyone always says that you need to right from the start. The problem with that is, if you've never done it before, how to you know the right way??
Or, if you've started out and you've been able to keep up with things for a while, but now you're so busy that you can't do it anymore. You might be looking to expand and take on employees.
Small business is rife with traps, even for the more experienced operators.
I can set you on the right path, keep it simple, save you time, keep you compliant and give you the peace of mind that everything's under control.

TESTIMONIALS
What my clients are saying
I have been working with Mick as my bookkeeper since 2022, and he has been an absolute asset to both me and my five businesses.
​
Mick set up my Xero systems across multiple businesses and my company, making what felt overwhelming actually make sense. He manages all of my BAS requirements with ease and consistency, and more importantly, he has taken the time to help me truly understand my financial reports, not just process them.
​
As a business owner juggling multiple ventures, having someone I trust completely with my numbers is everything. Mick is reliable, knowledgeable, and incredibly patient. He does not just “do the books”, he gives you clarity and confidence in your business.
​
I highly recommend Mick to anyone looking for a bookkeeper who goes above and beyond.

Justine Martin Corporation
I’ve worked with Mick for 2.5 years, and he has completely transformed how I understand and manage the financial side of my business. He set everything up so it runs smoothly in the background, giving me total peace of mind. If you’re starting a business, having a reliable bookkeeper is essential, and Mick is the best I’ve worked with.
Tristan Wilson
Mick's professionalism and knowledge has been paramount for myself and my business. Without his can-do attitude and attention to detail, I honestly would've struggled to build my business in a healthy manner. He really is the 1 stop shop that every emerging business needs in their corner!
Rob Moloney
I’ve been using Mick as my bookkeeper since starting my business about 3 and a half years ago, and honestly couldn’t recommend him more.
​
At the beginning I had pretty much no idea about the admin / finance side of things, and Mick went out of his way to help, even coming over on a Saturday to get everything set up properly and show my wife and I how it all works.
​
Since then he’s always been easy to deal with, super approachable, and happy to help whenever something comes up. He explains things in a way that actually makes sense, which has been a huge help.
