Welcome to Billing Saathi: what you can do
Billing Saathi is an online GST billing, inventory and accounting app for small and growing businesses. It runs in your web browser at app.billingsaathi.com on a computer, tablet or phone — there is nothing to install.
It works for any type of business: retail shops, mobile and electronics shops, wholesalers, manufacturers, service businesses, restaurants, medical stores and grocery shops. Features like IMEI tracking or batch numbers are optional — switch them on only for the products that need them.

GST made simple
- Every invoice line carries an HSN/SAC code, GST rate and taxable value.
- CGST + SGST is applied for sales inside your state and IGST for sales to another state, based on the Place of Supply.
- At month end, the GST Report, GSTR-1 and GSTR-3B are already worked out from your bills. Always check the figures with your accountant before filing.
