Sarosh and his team are very good. I am new to business and often as with other startups, accounting was not my forte. Now ask me about events and planning and i'm your girl. When I started to look at dealing with my business finances it all started to look a bit daunting, Enter Sarosh. Sarosh was recommended to me by a friend. He came and visited my office and spent alot of time helping me understand what we needed to do and how. Sarosh took on all accounting responsibilities for my company and even saved us alot of money in the process. Thank you

Sarosh and his team are friendly and approachable. They respond swiftly to calls and emails and will make time to sit and talk through any issues. I especially appreciate the way that I can "say it how it is" at times. They patiently listen and explain things, clearly knowledgeable and well qualified in their field. I have found their services to be affordable and for myself very good value. Thank you Sarosh and team!
