AVMK Accountants was built to provide business owners with something most never get from their accountant, clear financial visibility, proper control, and support in making better decisions.
Meet the Founder
Karthik Vasanthakumar
Chartered Management Accountant | MBA (Finance) | 200+ businesses supported
Karthik is a commercially focused Financial Controller with over 15 years’ experience supporting businesses across multiple sectors.
He has led finance functions, produced board-level reporting, and worked closely with business owners and senior management teams to improve financial clarity, strengthen controls, and support strategic decision-making.
Having seen first-hand how many businesses operate without reliable numbers or proper financial oversight, AVMK was built to bridge that gap — providing Financial Controller-level support without the cost of hiring in-house.
What makes AVMK different
Finance Ownership
We don’t just prepare numbers, we take responsibility for how your finance function runs.
Clarity Over Complexity
You get clear, structured financial insight you can actually use.
Commercial Focus
We look beyond compliance to help you improve profitability, cashflow, and decision-making.
Reliable Support
No chasing, no last-minute surprises — just structured, ongoing financial oversight.
Our goal is simple — to give you the clarity and control needed to run your business properly and make confident financial decisions.
“We understand what it’s like to run a business and the pressure that comes with making financial decisions without clear numbers.”
Right from the beginning, Karthik was answering questions before I even asked them. He reviewed my accounts and suggested tax-efficient ways of running my business that completely changed how things worked.
