What clients say
I've hired Sourav 5 times. He exceeds our expectations EVERY SINGLE TIME. 5-star service! I wish he was in my office in the USA.

Questions
Do you understand accounting, or only Excel?
Both. I have a B.Com in Accounts and three years as a senior accountant, so the tools follow how the books actually work.
Can it work with QuickBooks or my bank exports?
Yes. I build imports for the export files your bank, QuickBooks or other software already produce.
Can you build it without seeing my real figures?
Yes. I can build with sample data and you plug in the real file at the end.
How long does it take?
Small fixes are often done the same or next day. Most builds take 2 to 3 days, and bigger systems about a week with a first version in 2 days. If you have a deadline, tell me and I will work to it.
