Best GST billing software in India (2026)
Choosing GST billing software feels daunting when every app claims to be 'the best'. This guide compares five popular options — free plans, feature depth, pricing and the real edge of each — so you can pick the right tool without wasting a trial.
What to look for in GST billing software
Every GSTIN-registered business must issue invoices with the correct CGST/SGST or IGST split, sequential invoice numbers, HSN/SAC codes, and the buyer's GSTIN (where applicable). Beyond the legal minimum, useful GST billing software should also handle inventory management, purchase orders, GSTR-ready summary reports, and PDF sharing via WhatsApp. The table below scores five apps across these dimensions.

App-by-app breakdown
BillRaja — best for multi-format small businesses
BillRaja bundles three business types into one app: retail GST billing with stock & purchase orders, restaurant billing with KOT and a public QR menu, and membership management for gyms and coaching centres. Every invoice is GST-compliant (CGST/SGST or IGST, HSN codes, sequential BR-YYYY-NNNNN numbering). The customer bill portal lets buyers review their bills with a phone+OTP login. A 3-month trial leads into a free plan, then Pro at ₹99/month and Enterprise at ₹199/month. Offline-first.
Vyapar — best for established desktop + Android users
Vyapar is one of India's most widely used GST billing apps, with a large community and a well-regarded Windows desktop app alongside Android. It supports GST invoicing, inventory, purchase orders, and bank reconciliation. The free Android plan is functional; the Windows app requires a paid subscription (from around ₹1,499/year). It does not include a restaurant or membership module. Read the BillRaja vs Vyapar comparison for a deeper dive.
myBillBook — best for FMCG distributors and retailers
myBillBook targets distributors and product-heavy retailers with strong barcode scanning, batch and expiry tracking, and a salesman-route-tracking feature. GST invoicing and stock management are solid. The free tier is limited; paid plans start at around ₹399/month. No dedicated restaurant or membership workspace.
Zoho Invoice — best for service businesses with a customer portal
Zoho Invoice is permanently free for up to 1,000 invoices per year. It offers a polished customer portal, recurring billing, and strong multi-currency support — ideal for consultants and service agencies. Inventory is handled by the separate Zoho Inventory module (paid). Offline use is limited; it works best with a stable internet connection.
Khatabook — best for micro businesses tracking credit
Khatabook started as a digital ledger (udhaar khata) and added basic GST invoicing. It excels at tracking credit extended to customers, sending payment reminders via SMS/WhatsApp, and working on entry-level Android phones. HSN code support is limited and it lacks purchase orders and detailed inventory management.
Where BillRaja fits
BillRaja's genuine edge is its 3-in-1 workspace: a single app that handles retail, restaurant and membership billing without forcing you to pay for separate specialised tools. Other highlights:
- Public QR menu — restaurants can share a live digital menu with no extra subscription.
- Customer bill portal at /customer — customers verify their identity with phone+OTP and view all their bills, reducing "where's my invoice?" calls.
- Offline-first — bills keep printing even when the mobile data or Wi-Fi drops.
- GSTR-3B-ready reports — HSN-wise tax summaries you can hand to your CA without re-keying data.
- Affordable — free plan is generous; Pro at ₹99/month is one of the lowest paid tiers in this category.
BillRaja is not the right choice if you need a full-featured Windows desktop accounting suite (Vyapar or Tally is better) or multi-currency international invoicing (Zoho Invoice or Zoho Books).
Verdict
For a GST-registered Indian small business that bills in retail, runs a small restaurant, or manages memberships, BillRaja's free plan is the most feature-complete starting point. Vyapar is the better choice if you need a Windows desktop app or an established ecosystem. myBillBook wins for FMCG distribution. Zoho Invoice leads for pure service businesses needing a customer portal without inventory complexity.
