Kushan Patel's Review Sourced from Google
Very poor experience, i have been follwoing up for more than 08 months for simple accouting work, which BDO's Sr manager(Adelaide Office) was not able to address. Simply delaying work without a reason. I have asked for refund, which they promised and never paid back. Stay away at all cost.

InlineAdam's Review Sourced from Google
So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

Alex Stackhouse's Review Sourced from Google
Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

Having a good experience with BGW after our longtime accountant retired in 2024. Working with Ken L at BGW has been nice, he is responsive, knowledgeable and has a good understanding of how to use his resources within BGW. BGW as a company does some unique things, including regular podcasts about macro concepts and other relevant news that impacts their customer base. They are truly Anything But Typical!

Highly Recommend BGW! Working with them has been a pleasure and one of the best decisions made for our firm. When we first started working with BGW, our accounting was in complete disarray, but thanks to their resilient effort, constant support, and great team, they have managed to bring our accounting up to date! Thanks to BGW, our firm can focus on growing and be confident that our finances are in great hands. They have become a crucial partner for our organization, and we look forward to many more years working with them. I cannot emphasize enough how grateful I am for their guidance, support, and expertise. I highly recommend to any business owner looking for a firm they can trust and grow with to choose BGW; they are the best!
