GST billing, stock and filing in one app
Brihat Books is cloud software for GST invoices, inventory and light accounting. Use it in a browser, or on Android and iOS.

Billing and tax
The app works out CGST, SGST, IGST and cess on each invoice. It also issues credit notes and e-way bills. Send an invoice on WhatsApp, and collect payment by UPI on the Pro plan.
Stock and branches
Track inventory across more than one warehouse. Several users can work in one book, and a business can run several branches. A shop with two godowns and a counter in each town sees stock for every location in one place.
Filing returns
On the Pro plan, Books files GSTR-1 and GSTR-3B from the invoices you have entered. A chartered accountant gets one login through the CA portal that opens many client books, and moves from one client to the next without signing out.
Sarthi, the assistant
Type a question the way you would put it to your accountant, in Hindi or English, and Sarthi replies from your books. It is an AI assistant, so treat a figure it gives as a prompt to open the report and confirm.

Where invoices, stock and returns meet
Books keeps invoices, stock and tax figures in one book, so the GST return draws on the same entries your team already made. It is billing software with light accounting, built for small and mid-size businesses that file GST every month.
At the counter and at the desk
Raise an invoice from the web app, or from your phone at the counter. The tax lines fill in on their own, so nobody works out the CGST, SGST and IGST split by hand. A WhatsApp bot takes the same kind of requests from your chat.
