About A B C S UK
We're not your typical Accountants; and that's exactly why clients stay.
​
At A B C S UK, we believe bookkeeping and accountancy should do more than keep HMRC happy; it should give you clarity, confidence and accurate data to drive better business decisions.
Led by multi-award-winning bookkeeper, accountant and founder Stephanie Marshall FICB PM.Dip ICPA, we’re here to support your business like it’s our own. You can expect straight-talking advice, reliable numbers, regular communication and effective strategies that actually make sense.
Whether you’re just starting out or scaling up, you’ll get real support that grows with you, not a once-a-year meeting and a confusing spreadsheet.
Meet Stephanie
Stephanie Marshall FICB PM.Dip ICPA
Founder. CEO. Fellow of the Institute of Certified Bookkeepers. Independent Certified Practising Accountant and according to one client, “the Mary Poppins of the bookkeeping world.”
Stephanie has spent over a decade helping businesses across the UK get clear on their numbers; from family-run sole traders to national organisations with complex accounts.
After qualifying as a Bookkeeper and Independent Certified Practising Accountant, she realised something most practices miss: business owners don’t need just tax returns, they need someone who actually understands their business...That’s where A B C S UK came in.
Stephanie built the firm to offer bookkeeping and accountancy services as well as strategy and business development support that’s tailored, not templated. Each package is designed around real businesses, real goals and real people. We don't just tick boxes.
Stephanie is currently supporting many small businesses through the transition to Making Tax Digital for Income Tax, helping them prepare early, get the right systems in place and avoid last-minute stress.
She specialises in working with family-owned businesses that have big ambitions and bold goals — the kind who want more than just a tax return and a wave goodbye at year-end. The kind that want real support, regular check-ins and someone who’s as invested in their success as they are.
Because she knows that when your numbers are under control, your whole business can change for the better.
