The challenge
Why we built it
Many Indian businesses — from shops and traders to factories and service providers — still write bills by hand or wrestle with complicated accounting software, then send photos of every bill to their accountant on WhatsApp. They need GST-correct invoices, fast, from the phone in their pocket — and their accountant needs every bill without chasing for it. Parchi set out to serve both, without any training.
Our approach
How we designed and built it
Three steps to a bill
Type the customer, add items, share. Parchi remembers every customer, GSTIN, item, HSN code, rate and GST % from earlier bills, so repeat invoices fill in by themselves.
GST handled automatically
CGST + SGST or IGST chosen automatically from the place of supply (defaulting to the customer’s state), HSN summary, amount in words in lakh/crore and round-off — on the classic Indian GST A4 print layout. Works for businesses with or without a GST number, with prices typed with or without GST (MRP).
Built for the business and its accountant
Role-based team access (owner, admin, billing staff, accountant, viewer) and a business switcher for accountants with many clients. The accountant sees every bill as soon as it is made and downloads any period as Excel-ready CSVs or one PDF — no more photos of bills.
