GST Billing Software is a business tool that helps Indian businesses issue tax-compliant invoices, calculate Central GST, State GST and Integrated GST automatically based on the buyer's state, generate E-way bills and E-Invoices with an Invoice Reference Number, and produce GSTR-1, GSTR-3B and GSTR-9 filing summaries ready to upload to the GST portal.
A good GST billing platform goes beyond invoicing. It manages your customer and supplier master data with automatic GSTIN verification, tracks inventory and stock movements across multiple warehouses, offers point-of-sale billing for retail counters, and lets you share documents securely with your customers — via WhatsApp, email or a signed magic link that opens a fully rendered invoice with a UPI QR code.
Deccan Bill is built specifically for the Indian small-business context. Every invoice is a valid tax invoice under the GST Act, HSN and SAC codes are looked up automatically, and the whole platform runs on the cloud so you can bill from your shop counter, from a client meeting on your phone, or from home — with the same data, the same reports, and no separate licences for each device.
From your first GST invoice to multi-branch inventory — Deccan Bill covers the full billing, POS, inventory and compliance workflow in one platform.

"Switched from desktop accounting to Deccan Bill last quarter. GSTR-1 export saves me 4 hours a month. The magic-link feature is a hit with my B2B customers — they click, pay UPI, done."
Rajesh Kumar
Owner, Kumar Electronics · Mumbai
"Free plan handles all my invoicing. WhatsApp sharing means my customers get invoices instantly — no more "please email again" calls. Support responded within 20 minutes when I had a GSTIN query."
Priya Sharma
Founder, Sharma Textiles · Delhi
"The POS is exactly what my retail shop needed — barcode scan, thermal print, UPI QR on the bill. My cashier learnt it in one afternoon. GST auto-calculation is perfect every time."
Mohammed Ali
Proprietor, Ali Traders · Hyderabad
"Multi-warehouse stock was the deal breaker for us — three branches, one dashboard. Low-stock alerts have already prevented two lost sales this month. Cloud-based means I can check numbers from home."
Vikram Reddy
CEO, Reddy Hardware · Bengaluru
"HSN codes for medicine, credit notes for returns, e-way bill for wholesale supply — everything a pharmacy needs, in one place. And it is genuinely free for the basic plan."
Anita Patel
Partner, Patel Pharmacy · Ahmedabad
"Quotations that convert to invoices with one click saved my sales team hours per week. The referral program helped us bring on three partner businesses. Great software, great team."
