I have run companies in India since 2013. One of them, a D2C business, crossed ₹100 crore in revenue.
I still kept my own profit and loss in a Google Sheet, because I did not trust the one I was sent.
My books ran a month or two behind. Notices arrived that nobody expected. Every mistake became my problem, and my cost.
The problem was never one person. It was work still done by hand, by people with too many clients and not enough hours. That part can be fixed now. So we fixed it.
