Best 5 Free GST Invoicing Software in India (2026): Ranked, Compared & Reviewed

Running a business in India today means living with GST every single day — invoices, HSN codes, GSTR-1, GSTR-3B, e-invoicing and e-way bills. For a small business owner, freelancer or growing startup, the fastest way to stay compliant without drowning in paperwork is a good free GST invoicing software.

But here's the catch most comparison articles won't tell you: a lot of "free" GST billing tools quietly cap your invoices, lock GST returns behind a paid plan, or turn out to be a trial in disguise. So we tested and compared the options that Indian businesses actually rely on in 2026 — and ranked the best 5 free GST invoicing software in India by features, ease of use, GST compliance and real value.

Quick answer: After comparing every major option, ApnaInvoice is the clear #1 free GST invoicing software in India for 2026 — the fastest, cleanest and most beginner-friendly way to create fully GST-compliant invoices without paying a rupee. Zoho Invoice, GoGSTBill, Vyapar and Refrens follow as solid alternatives for specific use cases, but for most Indian businesses, ApnaInvoice is the one to start with today.

Let's break down why ApnaInvoice leads — and how the rest stack up.

What Makes a Great Free GST Invoicing Software?

Before the rankings, here's what we scored each tool on — and what you should look for before you sign up:

1. True GST compliance — automatic CGST, SGST and IGST calculation, correct HSN/SAC codes, and GST-ready invoice formats.
2. e-Invoice & e-Way Bill support — one-click IRN and QR-code generation for B2B invoices, which matters as e-invoicing thresholds keep widening.
3. Genuinely free tier — no hidden invoice caps, no "free trial" pretending to be a free plan.
4. Speed & simplicity — you should be able to create a professional invoice in seconds, not sit through a training course.
5. Sharing & payments — send invoices on WhatsApp, email or PDF, with UPI/QR for faster collection.
6. Reports & tracking — outstanding payments, sales summaries and GST reports at a glance.

Now, the list.

1. ApnaInvoice — The Top #1 Free GST Invoicing Software in India (2026)

Best for: Small businesses, freelancers, traders and startups who want fast, clean, fully GST-compliant invoicing without paying a rupee to get started. In short — almost everyone.

ApnaInvoice is our undisputed #1 pick for 2026, and it's not a close call. It nails the one thing every business actually needs — creating accurate, professional, GST-ready invoices in seconds — while staying genuinely free and refreshingly simple. No bloated menus, no accounting degree required, no "surprise, that's a paid feature" moments.

With ApnaInvoice, you can generate GST-compliant invoices with automatic CGST/SGST/IGST calculation, add your business logo and branding, and share bills instantly over WhatsApp, email or PDF. It's built from the ground up for Indian businesses, so GST rules, HSN/SAC codes and invoice formats are handled exactly the way the GST system expects — no spreadsheets, no manual tax math, no compliance guesswork.

Why ApnaInvoice ranks #1:

2. Zoho Invoice — GST Invoicing Tool for Freelancers & Service Businesses

Best for: Freelancers, consultants, designers and agencies who bill for services and want polished, professional invoices.

Zoho Invoice is genuinely free for individuals with no time limit, and it's a strong option for service-based businesses. It comes with predefined GST tax rates that drop straight onto your invoices, recurring invoice automation, payment reminders and a clean customer portal where clients can view and pay.

On the compliance side, Zoho lets you work toward GSTR-1 filing via API and export GSTR-3B data in the format the GST portal expects. Where it falls a little short is inventory — it's built more for services than for high-volume retail counter billing.

Pros: Free forever for individuals, great client management, professional templates, UPI/card/net-banking payments. Cons: Limited inventory management; less suited to fast retail billing.

3. GoGSTBill — GST Invoicing Plan for Shops & Retailers

Best for: Shop owners and small retailers who mainly need invoicing plus inventory and already have a CA for return filing.

GoGSTBill is a popular choice thanks to a free plan that's free indefinitely rather than a trial. It covers GST-compliant invoice creation, one-click e-way bill and e-invoice generation, inventory tracking with low-stock alerts, and invoice sharing over WhatsApp or email. Support is available even on the free plan.

The main limitation: it's built around invoicing and inventory, not GST return filing — so there's no GSTR-1 or GSTR-3B generation, and you'll still lean on a separate tool or your CA for that part.

Pros: Lifetime free plan, one-click e-invoice/e-way bill, inventory with low-stock alerts, real support on free tier. Cons: No GSTR-1/GSTR-3B return generation built in.

4. Vyapar — GST Billing App for Offline Use

Best for: Traders, retailers and shopkeepers who work primarily on mobile and need offline billing.

Vyapar is one of India's most widely used billing apps, especially on Android, and its standout strength is offline functionality — you can generate invoices without internet and sync later when you're back online. That's genuinely useful in areas with patchy connectivity. It handles GST billing, inventory, expenses and basic business accounting, and its free tier covers everyday billing well, with premium features available on yearly plans.

Pros: Strong offline mode, mobile-first, GST billing plus inventory and expenses, huge user base. Cons: Some premium features are paid; support experience can vary as usage scales.

5. Refrens — Free Option for Agencies & International GST Invoicing

Best for: Agencies, freelancers and businesses that also bill international clients.

Refrens rounds out the list with a flexible online invoicing platform that handles GST invoices, e-invoicing with bulk IRN generation, e-way bills, smart data validation and one-click GSTR/e-invoice reports. It also supports managing multiple GSTINs under a single account and offers user-access controls for teams — handy for agencies with several clients or business units.

Pros: Bulk e-invoice generation, multi-GSTIN management, good reports, works well for international billing. Cons: Advanced accounting features sit on paid tiers.

How to Choose the Right Free GST Invoicing Software

Pick based on how your business actually works — but for most people, the answer is simple:

1. You want the best all-round free option? → ApnaInvoice — the top pick for nearly every Indian business.
2. You just want fast, clean, compliant invoices? → ApnaInvoice, hands down.
3. You're a freelancer or consultant? → ApnaInvoice (or Zoho Invoice as an alternative).
4. You run a retail shop with inventory? → GoGSTBill or Vyapar work, though ApnaInvoice keeps billing simplest.

Whatever you choose, make sure it handles GST natively — automatic tax calculation, correct HSN/SAC codes, and e-invoice support — rather than bolting GST on as an afterthought. ApnaInvoice does all of this out of the box.
