Every great business begins with a simple idea. Ours was this: owner‑managed companies deserve the same world‑class financial expertise that global blue‑chip organisations rely on — delivered with clarity, care, and a genuine commitment to helping them grow.



MyController was built to close that gap. Today, we deliver fixed‑fee, award‑winning compliance and advisory services that help businesses drive profit, improve cash flow, and create lasting value. But the journey to get here is just as important as the services we provide.

How It Started: A New Kind of Accountant

MyController began in the most humble of settings — a bedroom office — but with a bold mission. Traditional accounting often focused on the past. We wanted to build something different: a proactive, forward‑looking service that helped businesses boost profit without working harder, using proven blue‑chip best practices.

Word spread quickly. As demand grew, we moved into serviced offices, refining our approach and developing the hands‑on, partnership‑driven model that still defines us today.

Growing the Right Way: Our Windsor Home

By practising the same strategic planning and financial discipline we teach our clients, we reached a major milestone in 2013: we purchased our own offices in Windsor.

This wasn’t just a property decision — it was a statement of intent. A commitment to long‑term value. A belief in building something that lasts. And a promise to remain rooted in the community we serve.

Recognition for Doing Things Properly

In 2014, we won our first award — alongside KPMG — and we’ve won one every year since. We’re also proud to be Platinum Approved Employers with ACCA, a recognition of our dedication to excellence, training, and professional development.

These achievements aren’t just trophies. They’re proof that our approach works, and that our impact is real.

Sharing Knowledge: Books, Tools & The Business Academy

Our commitment to helping businesses grow goes far beyond compliance.

Our book, Running a Better Business, inspired by MBA and PhD‑level research, laid the foundation for our online Business Academy: PathwaytoProfit.club.

This platform gives clients access to practical tools, insights, and strategies to improve profit, strengthen cash flow, and build long‑term value.

And with a library of over 500 guidance notes, we ensure our clients always have the right information at the right time. Because being proactive isn’t a slogan for us — it’s how we operate.

The Founders: Greg & Debbie Parrish

MyController is shaped by the experience and values of its founders.

Greg Parrish

A Fellow of both ACCA and CIMA, Greg has held senior roles in blue‑chip organisations and served as Vice President of CIMA’s Berkshire Branch. His MBA and research into applying Option Pricing Theory to strategic decision‑making bring a rare depth of insight to owner‑managed businesses.

Debbie Parrish

With over 30 years of experience in financial control across the UK and USA — including roles at Mars, GSK, Great Western Bank (California), Safeway, and ICI — Debbie brings unmatched expertise in improving financial systems and driving profitability.

Together, Greg and Debbie built MyController on a simple belief: great businesses deserve great support.

The Future: Your Trusted Business Accounting Partner

Today, MyController operates on a fixed‑fee, service‑level basis — and when we say fixed, we mean it. No surprises. No hidden costs. Just dependable, expert support that integrates seamlessly into your team.

We don’t just work for our clients — we work with them. Every service level includes:

• A tailored Client Calendar
• Regular meetings
• Telephone and email support
• Proactive reminders and guidance

So you’re never left in the dark, and never left behind.

Our goal is simple: to help you build a stronger, more profitable, more resilient business — one smart decision at a time.

Let’s grow together.
