Which is the best free GST billing software for small business in India?

For online sellers and e-commerce businesses, myBillPlease is the best free option — it offers unlimited invoices, Shopify integration, full GST compliance across all slabs (including new GST 2.0 rates), and GSTR reports at zero cost. For offline retail shops, Vyapar is excellent but costs ₹3,499/year after the free trial. For freelancers and service businesses, Zoho Invoice offers a genuinely free unlimited plan in India. The best choice depends on your business model — there is no single winner for every type of business.

Is Vyapar completely free or does it have a paid plan?

Vyapar is not permanently free. It offers a 14-day free trial of the full-featured app. After the trial, the Android app costs ₹3,499/year and the desktop (Windows) version costs ₹5,999/year. There is no free permanent tier for Vyapar — the trial is just a test period. This is a common misconception because Vyapar markets itself as affordable, but it is not free software. If you need a permanently free option, consider myBillPlease or Zoho Invoice instead.

Can I use billing software without internet in India?

Yes, but your options are limited. Vyapar and myBillBook both have offline modes for Android and Windows — you can create invoices without internet and sync when connectivity returns. Most web-based billing tools like myBillPlease, Zoho Invoice, and Refrens require internet access. If you run a shop in an area with unreliable connectivity, Vyapar's offline Android app is likely your best bet, even though it requires a paid subscription after the trial period ends.

What features should free GST billing software have?

At minimum, free GST billing software must include: GST invoice format with all 16 mandatory fields (GSTIN, HSN/SAC codes, tax breakdowns by CGST/SGST/IGST), support for all current GST slabs (0%, 5%, 18%, 40% after GST 2.0), GSTR-1 report export in the format accepted by the GST portal, customer and product/service catalog management, and the ability to send invoices via email or WhatsApp. E-invoicing (IRN generation) is required only if your annual turnover exceeds ₹5 crore. Most free tools include the basics but restrict advanced features like multi-user access or bulk operations.

Is ClearTax a billing software or a filing tool?

ClearTax is primarily a GST return filing and compliance platform — it is not a billing software. ClearTax does not generate sales invoices. It is designed to help businesses file GSTR-1, GSTR-3B, and annual returns, and it offers CA-assisted services. Many businesses use ClearTax alongside a billing tool — they create invoices in tools like myBillPlease or Vyapar, and then file returns either directly from the billing tool or through ClearTax. Do not confuse the two categories of software.

Which free billing app works best on Android in India?

Vyapar is the most downloaded and highest-rated billing app on Android in India, with a particularly strong offline mode and inventory features built for physical retailers. However, it shifts to a paid model after 14 days. Among permanently free Android options, Swipe and GimBooks are well-designed for service businesses and freelancers. myBillPlease works on Android via the browser with a mobile-optimized interface. myBillBook is a solid free option for traders and distributors who need basic stock management alongside invoicing.

Does free billing software support e-invoicing (IRN generation)?

E-invoicing (generating an Invoice Reference Number via the NIC IRP portal) is a compliance requirement only for businesses with annual turnover above ₹5 crore. Among free billing tools, myBillPlease supports e-invoicing directly from the dashboard at no extra charge. Most other free tools either do not support e-invoicing or require you to upgrade to a paid plan. If your business is above the ₹5 crore threshold, verify e-invoicing support before choosing a billing tool — non-compliance attracts a penalty of ₹10,000 per invoice.

Key takeaways

Vyapar is not permanently free: the 14-day trial ends at ₹3,499/year on Android and ₹5,999/year on Windows.
Zoho Invoice is genuinely free for Indian businesses up to 1,000 invoices a year, with multi-currency billing for international clients.
ClearTax files GST returns; it does not create invoices, so it complements rather than replaces a billing tool.
Offline billing only exists in Vyapar and myBillBook; web tools like myBillPlease, Zoho Invoice and Refrens need internet.

Why Choosing the Right Billing Software Matters in 2026

India has over 63 million small and medium businesses. The vast majority are still generating invoices in Excel or on paper. That creates two problems: GST compliance risk and wasted hours. A missed HSN code or wrong tax rate can trigger a notice from the department. Manual invoicing on Excel means no auto-calculations, no GSTR reports, and no audit trail.

The good news is that several genuinely free billing tools have emerged for Indian businesses. We tested all 10 of the most popular options — looking at what is actually free (not just a 7-day trial), GST compliance depth, platform availability, and the critical features small businesses need. We are honest about every tool's weaknesses. This is not a paid rankings list.

If you create GST invoices regularly, use our free invoice generator to see what compliant invoices look like. Or jump straight to the comparison table below to see how all 10 tools stack up on features and pricing.

1. myBillPlease — Best Free Option for E-Commerce and GST-Registered Businesses

What it does well: myBillPlease is the only billing software on this list with native Shopify integration. If you sell on Shopify, your orders automatically generate GST-compliant invoices without any manual work. The free plan includes unlimited invoices, all GST slabs (0%, 5%, 18%, 40%), HSN/SAC code lookup, GSTR-1 and GSTR-3B reports, and e-invoicing for businesses above the turnover threshold.

GST compliance: Full. All new GST 2.0 rates are built in. The invoice format includes all 16 mandatory fields required by CGST Rules — supplier GSTIN, buyer GSTIN, HSN code, tax breakdowns (CGST, SGST, IGST), place of supply, reverse charge indicator. You can generate IRN (Invoice Reference Number) directly from the dashboard if you are above ₹5 crore turnover.

Limitations: No offline mode. If you are in a low-connectivity area and need to create invoices without internet, myBillPlease does not work. For that specific use case, Vyapar or myBillBook are better options.

Pricing: Free plan is genuinely unlimited for core invoicing. Paid plans add multi-user access and advanced inventory. See full pricing here.

2. Vyapar — Best for Offline Retail Shops

What it does well: Vyapar is the most popular billing app for Android in India and for good reason. It works completely offline — critical for retailers in tier-2 and tier-3 cities with patchy internet. The inventory management is excellent for physical retailers, with barcode scanning, stock alerts, and reorder reminders. The UX is designed for someone who has never used billing software before.

GST compliance: Strong. Supports all GST formats — regular, composition, and reverse charge. GSTR reports are accurate and export to the format accepted by the GST portal.

Limitations: The free version is a 14-day trial, not a permanent free plan. After the trial, you pay ₹3,499/year for the Android app or ₹5,999/year for the desktop version. There is no web version — you are tied to your device. No Shopify or e-commerce integration. If your business moves online, Vyapar does not scale well.

Verdict: Best for brick-and-mortar retailers who need offline billing. Not ideal if you want a free permanent plan or sell online.

3. Zoho Invoice — Best for Service Businesses with International Clients

What it does well: Zoho Invoice is genuinely free for Indian businesses — they removed the paid tier for India in 2023. It supports multi-currency invoicing, making it the best option for Indian freelancers and agencies billing international clients in USD, EUR, or GBP. The client portal lets customers view invoices and make payments online. Recurring invoices work well for subscription-based services.

GST compliance: Solid. All GST formats supported. Integrates with Zoho Books for full accounting if you need it later.

Limitations: Free up to 1,000 invoices per year (about 83/month). Businesses with higher volume need Zoho Books (paid). The interface is more complex than Vyapar or myBillPlease — there is a learning curve. If you only need simple GST invoices, Zoho Invoice is overkill. Also, you are locked into the Zoho ecosystem — data portability is limited.

Verdict: Ideal for IT service companies, consultants, and agencies with international clients. Over-engineered for a local kirana shop.

4–10: Swipe, GimBooks, Khata Billing, ClearTax, Sleek Bill, myBillBook, Refrens

Swipe (by Instamojo): Clean web and Android app focused on quick invoice creation. Free plan available with basic GST support. Works well for small service businesses. Main limitation: payment collection features require Instamojo payment gateway, which charges 2% per transaction. If you want truly fee-free invoicing, be aware of this.

GimBooks: A straightforward free billing app for freelancers and solo consultants. Supports GST invoices, expense tracking, and basic reports. The free plan is genuinely free without usage caps for individual users. Lacks inventory management, so not suitable for product sellers.

Khata Billing: Android-only app with a free version supported by ads. Very simple interface — designed for the smallest retailers who just need to send a quick invoice via WhatsApp. GST support is partial — works for basic invoices but advanced features like e-invoicing or GSTR reports are absent. Not suitable for registered businesses with monthly GSTR filing requirements.

ClearTax: Important clarification — ClearTax is a GST filing and return platform, not a billing software. It does not generate invoices. It is free for basic GST returns and paid for advanced features. We include it here because many searches for 'free billing software' surface ClearTax, but it does not replace a billing tool. Use it alongside a billing tool for filing returns.

Sleek Bill: Windows desktop software with a free plan capped at 25 invoices/month. Strong for manufacturing and wholesale businesses that need production-linked billing. The interface feels dated but the feature depth is good. Paid version starts at ₹5,000/year.

myBillBook: Popular Android and Windows app for traders and distributors. Free basic plan available. HSN code support is limited in the free tier — you often need to manually enter codes. Good for businesses that are not yet GST registered (composition scheme sellers). Once you need full GST compliance, the free tier becomes restrictive.

Refrens: Well-designed web-based invoicing tool popular with Indian freelancers and small agencies. Free plan allows 25 invoices/month and supports GST invoices. The proposal-to-invoice workflow is smooth. Paid plans unlock more invoices and client management. Best for project-based freelancers rather than product businesses.

How We Evaluated These Billing Tools

Genuinely Free

We only listed tools with a real free plan — not trials. We checked what you get without paying: invoice limits, feature caps, watermarks, and hidden costs.

GST Compliance Depth

A billing tool that does not handle all GST slabs, HSN codes, and GSTR report formats is not compliant. We tested each tool with real invoices across different tax scenarios.

Platform Availability

Can you use it on Android, web, and desktop? Does it have an offline mode? We checked whether the tool matches how real small business owners actually work.

Ease of Use

Creating an invoice should take under 2 minutes. We timed the process from opening the app to sending a GST invoice for each tool — first time, no tutorial.

E-Commerce Integration

With India's e-commerce boom, billing tools need to connect with Shopify, Amazon, and Flipkart. We checked native integrations vs manual workarounds.

GSTR Report Quality

The real test of a billing tool is whether its GSTR-1 export matches what the GST portal expects. We checked report format, data accuracy, and filing compatibility.

Our Recommendation: Match the Tool to Your Business Type

There is no single best billing software for every Indian business. Here is our honest recommendation based on business type:

Shopify or online seller: Use myBillPlease. It is the only tool with native Shopify integration and an unlimited free plan. Your orders auto-generate GST invoices — no manual work.

Offline retail shop in tier-2/3 city: Use Vyapar for its offline capability and strong Android app, but budget ₹3,499/year after the trial ends.

Freelancer or consultant: Use Zoho Invoice (free, unlimited) or Refrens (25 invoices/month free). Both have clean interfaces and multi-currency support.

Manufacturer or wholesale trader: Use Sleek Bill or myBillBook. The inventory depth suits product-heavy businesses better than simple invoice tools.

Not yet GST registered: Any tool works, but plan ahead — when you cross ₹40 lakh turnover (₹20 lakh for services), you will need full GST compliance. Tools like myBillPlease and Zoho Invoice handle the transition seamlessly.
