My Services
How White Mouse helps you

Bookkeeping and Financial Clarity
Reliable bookkeeping is the foundation of a well-run business.
I help keep accounts organised, accurate, and ready for your accountant without last-minute stress. With the right systems in place, business owners gain better visibility over how the business is performing.
Services may include:
- Ongoing bookkeeping
- Xero setup or clean-ups
- management reporting
- ensuring accounts stay organised throughout the year

Systems and Software Integrations
Most businesses rely on multiple software tools to run day-to-day operations. When these systems are set up properly and connected effectively, they save time and provide better visibility.
I help review, implement, and connect systems so they support the way the business actually operates.
This may include:
- accounting and payroll software setup
- integrating systems such as POS, payroll, job management, and time tracking
- workflow improvements and reporting visibility
- automation and AI-supported tools where appropriate
The focus is always on practical solutions that make the business easier to run.

Payroll, HR and Recruitment Support
Managing staff is a major part of running a business, but the administrative side of payroll and HR can quickly become time consuming.
I provide practical support across payroll processing, HR administration, and recruitment processes so business owners have reliable systems in place as their team grows.
This may include:
- payroll setup and processing
- HR administration support
- recruitment processes and documentation
- establishing simple and effective people systems

Operational Support
Many businesses benefit from having an experienced second set of eyes across the operational side of the business.
I provide steady support across areas such as reporting, systems, and operational processes so owners have clarity and confidence in how things are running.
Support may include:
- improving financial and operational visibility
- reviewing systems and processes
- identifying opportunities for improvement
- helping prioritise operational decisions
Support can be provided as a defined project or as an ongoing working relationship. For many clients, this ongoing support provides something just as valuable as the work itself.
Confidence and peace of mind that the business is running as it should.

How do I know if this is right for me?
You know you need help. You’re busy, but it still feels harder than it should. Things are spread across spreadsheets, emails and notes, and you don’t have a clear, reliable view of what’s going on.
Or you’re ready to grow, and want to make sure your systems and processes are sorted before you scale.
Do I need to have it all figured out first?
Not at all. Most of my clients come to me somewhere in the middle. We figure it out together.
What’s the first step?

What My Clients Are Saying
“I tried to keep on top of the accounts myself when I started out, but it got messy pretty quickly. Gemma came in and sorted everything out and now it just runs smoothly and stress free. I don’t have to think about it anymore and can get on with the work.”
“I’ve worked alongside Gemma for a number of years, and from an accountant’s perspective she makes life easy. Her clients’ accounts are always well maintained and accurate, which means year-end is smooth and efficient. She understands how to prepare accounts properly, not just process them.”
“It’s such a relief knowing I can just pick up the phone and call Gemma whenever I have a question about my business.
She always has the answers and makes things feel a lot clearer.”
