What billing software should actually do for you.
Most "billing software" in India was originally accounting software with an invoice module bolted on. It's built for CAs to audit, not for a shop owner to bill a customer in 30 seconds. We flipped that.
Invoices in under 2 minutes
Pick a customer, pick items, hit save. The customer's GSTIN, state, and tax treatment pre-fill from their record.
Purchases + input tax credit
Record vendor bills with CGST/SGST/IGST split. ITC flows into your monthly GSTR-3B automatically.
Payment tracking
Record full or partial payments against invoices. See outstanding aging by customer (0-30, 31-60, 61-90, 90+).
GSTR filing, in one click
Download GSTR-1 and GSTR-3B JSON ready to upload at gst.gov.in. No CA round-trip for routine months.
