What is GST Billing Software?

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.

What our customers say

Verified 5-star reviews from Indian business owners.

"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."

Suresh Iyer

Director, Iyer Corporate Gifts · Chennai

Frequently Asked Questions

Answers to the most common questions about GST billing on Deccan Bill.

What is GST Billing Software?

GST Billing Software is a tool that helps Indian businesses issue tax-compliant invoices, automatically calculate CGST, SGST and IGST, generate E-way bills and E-Invoices, and prepare GSTR-1, GSTR-3B and GSTR-9 filing summaries. Deccan Bill does all of this on the cloud, with a free plan for small businesses.

Is Deccan Bill really free?

Yes — the Starter plan is free forever with GST invoicing, quotations, customers, suppliers and basic reports. Paid plans unlock additional users, POS billing, advanced inventory across multiple warehouses, and automation. No credit card is required for the 14-day trial of the paid features.

Does Deccan Bill support E-Invoice (IRN) generation?

Yes. For businesses whose turnover crosses the IRN threshold, Deccan Bill supports E-Invoice generation with QR code and Invoice Reference Number, and E-way bill printing directly from the invoice screen.

Can I file GSTR-1 and GSTR-3B directly?

Deccan Bill produces filing-ready GSTR-1 (sales), GSTR-3B (summary) and GSTR-9 (annual) reports that you can export as JSON or Excel and upload to the GST portal. Direct portal filing via GSP is on our roadmap.

How does the magic-link invoice sharing work?

Every invoice, quotation and credit note gets a signed public URL that opens a rendered, mobile-friendly document — no login needed for your customer. You can also attach the server-generated PDF to the email. Views are tracked so you know exactly when the customer opens the invoice.

Can I share invoices on WhatsApp?

Yes — one tap opens WhatsApp with the invoice link, customer name and amount pre-filled. The link opens a fully rendered invoice with a UPI QR code, so customers can pay from the message thread.

Does it work on mobile?

Deccan Bill is a Progressive Web App (PWA), so you can install it from your Android Chrome or iPhone Safari like a native app. Full billing, POS, inventory and reports work on mobile, including offline invoice drafting.

Can I use it for multiple shops or warehouses?

Yes. Deccan Bill supports multi-warehouse stock, multi-counter POS, per-branch users with role-based access (Admin, Manager, Staff), and consolidated reports across all locations.

How secure is my business data?

Data is encrypted in transit and at rest. Authentication uses httpOnly session cookies to prevent XSS token theft. Strict multi-tenant isolation guarantees your data is never visible to another business on the platform. Daily automated backups are retained for 30 days.

Can I import my customers and products from another software?

Yes — customers, suppliers and products can be imported from Excel/CSV. Our team assists with one-time migration for businesses coming from desktop-based accounting software.

Do you offer support in Hindi and regional languages?

Support is available in English and Hindi over email and phone during business hours (Mon–Sat, 10 AM – 7 PM IST). Basic help documentation is available in Hindi.

Does Deccan Bill verify GSTIN automatically?

Yes. When you enter a customer or supplier GSTIN, Deccan Bill fetches the legal name, trade name, PAN, taxpayer type, constitution and registration status from the official GST database — so your master data stays clean and accurate.
