AN AUDIT SERVICE THAT'S MORE THAN JUST A TICK-BOX EXERCISE

 In today’s economic climate, many London-based businesses tell us the same thing — they’re not getting the support they need from their current audit firm. Have you seen your audit fees rise, but the level of service slip? We hear this often from businesses that turn to us after feeling let down by their previous firm. Some also feel they’ve outgrown their advisors, while others feel left behind. 

At AAB, we believe an audit should be more than a tick-box exercise. It should offer insight, spark better decisions, and give you confidence in where you’re headed. 

Our London team is part of a wider group with deep specialist knowledge across the UK and Ireland. That means we’re equipped to support businesses of all sizes, across all sectors, with practical advice, delivered when it matters most. 

We take the time to understand your world, ask the right questions, and offer more than just a year-end sign-off. We're here to help you save money, time, and sleep a little easier today, and as your business grows. 

“AAB’s Virtual Finance Function (VFF) solution has been instrumental in supporting our global growth. By managing day-to-day accounting, the VFF allows our in-house finance team to focus on group-level reporting, financial analysis, and strategic priorities. This has enabled us to expand efficiently and reduce the burden on our back-office operations.”
