Where are our company's details?

In Settings → Companies on the finance pages: the legal name, PAN, TAN, CIN, PF establishment code, ESIC employer code, registered state and address, email and website, the Tally company name, the bank account salaries are paid from, and your GST numbers (add one for each state you're registered in). Click Edit details to change them; saving asks for a six-digit code we email you.
