Helping Your Business Move Forward

Forecasting and planning so you always know what's coming and can act early.
Improved Profitability
We help you understand your margins and see where the profit really is.
More Time Back
We take bookkeeping, payroll and VAT off your plate so you can run the business.

Confidence to Grow
A finance partner beside you as you scale, backed by Xero Platinum expertise.
Why Growing Businesses Choose CASS

The Three Pillars of Smart Finance
Great finance isn't just about staying compliant — it's a way of thinking that turns your numbers into a genuine engine for growth. Everything we do is built around three simple shifts.
Accounting to Insights
We go beyond recording history. By turning your numbers into clear, forward-looking insights, we help you understand what's really driving your business — so you can make confident decisions based on facts, not guesswork.
Raising Funds to Designing Capital
Funding shouldn't be a last-minute scramble. We help you move from chasing finance when you need it to intentionally designing a capital structure that fuels sustainable, profitable growth.
Moving from Dependency to Resilience
A business that relies on one person is fragile. We help you build the systems, cash discipline and financial resilience that let your business thrive — with less dependency and more freedom.

Meet the TeamPaul Barnes
Founder & Managing Director
Paul founded CASS in 2017 with a simple belief: business owners deserve far more than a once-a-year set of accounts and a tax bill. He believes accounting should provide the clarity and confidence to make better decisions throughout the year, helping businesses grow stronger, become more profitable and avoid costly mistakes before they happen.
His route into accounting wasn't the traditional one. After leaving professional football, Paul built his career in finance, business systems and process improvement. He later became Finance Director in a growing business, giving him first-hand experience of the pressures, opportunities and challenges that business owners face every day. Those experiences shaped the philosophy that still drives CASS today: Giving You More Than Numbers.
Today, Paul leads an award-winning Xero Platinum Partner practice supporting more than 150 businesses across the UK. Alongside helping clients build stronger businesses, he regularly speaks on business growth and financial strategy, hosts the Giving You More Than Numbers podcast, is the author of The Three Pillars of Smart Finance, and continues to develop innovative technology that helps businesses and accountants work smarter. His passion remains the same as it was when CASS was founded: giving business owners the insight, confidence and support they need to make better decisions and build businesses that thrive.
