Diana Youssef

“BTG recently performed a thorough indirect tax review of the Group’s past 4 years of supplier payments. This involved a vast quantity of work, which the BTG team completed in good time and to a high quality. BTG’s expertise in this area meant their feedback was well-informed and their process improvements will benefit the Group. Overall, the service provided by BTG represented fantastic value for money and I would recommend them to any organisation who wants to understand how much unclaimed GST they can recover.”
Andrew Lewis

“We had the challenge of scrutiny from the ATO into our indirect taxes plus the desire to adopt “best practice” within our business divisions. We engaged Nabil and the team from BTG to review our practises and implement improvements as required to be best in class. This has resulted in GST recoveries, a Board endorsed assurance program and an enhanced finance team. BTG’s ability to deliver timely & professional services to our business was the most pleasing aspect of our BTG engagement.”
