About us
More than a
compliance exercise.
Bringing big-firm experience to growing businesses across the North West.
Bringing big-firm experience to growing businesses across the North West.
At ON Advisory Group, we believe accounting should be more than a compliance exercise.
We work with businesses across Lancashire, Manchester and the wider North West to remove the burden of financial management—while providing the clarity and insight needed to support growth.
Our goal is simple:
ON Advisory Group was founded by Bilal Natha and Mohammad Omar. Between us, we bring a combination of Big 4 training and senior industry experience.
We both trained and developed our technical foundations at Deloitte, one of the world's leading professional services firms—building deep expertise in audit, financial reporting, and complex accounting environments.
We have also held senior finance roles within EG Group, working within a fast-paced, international business environment.
Our founders are fully qualified chartered accountants and members of the UK’s leading professional body. We also partner with industry-leading software providers to deliver modern, cloud-based finance.
Both founders are Associate Chartered Accountants — the UK’s premier accountancy qualification, awarded by the ICAEW after rigorous examinations and practical training.
Members of the Institute of Chartered Accountants in England and Wales — the UK’s leading professional body for chartered accountants, governing standards of ethics and conduct since 1880.
Certified Xero Partner, delivering modern cloud accounting that gives you real-time visibility of your numbers, automated bookkeeping, and seamless Making Tax Digital compliance.
Many small and medium-sized businesses are underserved by traditional accountants—receiving basic compliance services but little in the way of real support or insight.
At the same time, the level of financial expertise available to larger organisations is often out of reach.
We created ON Advisory Group to bridge that gap.
As a young and dynamic team, we are:
Rather than reactive—we anticipate rather than respond.
Accessible when you need us, not just once a year.
Focused on building lasting relationships with our clients.
We take the time to understand your business, your challenges, and your goals—so we can provide support that actually adds value.
To be more than accountants—to be trusted advisors supporting our clients at every stage of their journey.
