From sole trader to limited company — we handle the setup, registration, and ongoing compliance.
Most accountants talk at you. We talk with you. No confusing terminology, no hidden fees, and no surprises at year end. Just clear, honest advice that helps your business thrive.
"Greenstone saved me over £4,000 in my first year just by restructuring how I take income. They actually care about helping you keep more of what you earn."
"After years of doing my own accounts, switching to Greenstone was the best business decision I've made. They handle everything and I actually understand my finances now."
"Professional, responsive, and genuinely helpful. They took the stress out of our first VAT return and have been brilliant ever since. Can't recommend them enough."
Clear, fixed-fee accounting services for sole traders, freelancers, and small businesses.
Prices are plus VAT. Custom packages available for larger businesses — get in touch.
A small, dedicated team of accountants who believe your finances should empower you, not overwhelm you.
Greenstone was founded in 2014 by Sarah Greenwood, a chartered accountant who spent a decade in large firms before realising that small businesses deserved better than being treated like a number.
Today, our team of five looks after over 500 sole traders, freelancers, and small businesses across London and beyond. We're big enough to handle complexity, small enough to know your name.
We're ACCA-qualified, HMRC-registered, and professionally indemnified. But more importantly, we're the accountants you'll actually enjoy talking to.
Fixed fees, clear communication, no surprises. You'll always know what you're paying and why.
You get a dedicated accountant who knows your business inside and out. Not a call centre.
We don't just file your returns. We actively look for ways to save you money and grow your business.
Book your free consultation or send us a question. We'd love to hear from you.
Whether you're a sole trader filing your first return or an established business looking to switch accountants — we're here to help. Your first consultation is completely free.
