Garment business
made simple!
I used to spend 8-10 hours every month on managing GST and TDS. With OpenBook things have changed. I can now do GST, TDS and accounting in one app. My favourite part being that it gives me more time for my business than calculations.

It was difficult to keep track of all the bills being managed in physical form. I find OpenBook helpful as it reduces my effort to track accounting & manage cashflow.
