What Is the Best Free GST Invoice Generator in India (2026)?

Most "best free GST invoice generator" lists are published by the tools themselves, ranking their own product first. This one ranks by use-case instead. Pick the column that matches your job, not a single trophy.

Two things the trophy lists skip: the pricing model (a flat monthly fee costs the same in the months you barely use it) and how a "free" tool pays its bills. The comparison below names both.

One rule applies to every tool: under Section 31 of the CGST Act, only a GST-registered business may issue a tax invoice with GSTIN and CGST/SGST/IGST lines. Below the registration threshold you issue a bill of supply, not a GST invoice, whatever tool you use.

Most lists rank by feature count, which always favours the biggest suite. This one reads by the job our user has: make a compliant invoice now, fast, without signing up, without handing over data, and without a subscription to feed. On those axes the suites are not ahead, they are differently shaped. Each "strength" below carries a cost, named in the same line.

Subscription invoicing tools are cheapest per invoice in your busiest months and most expensive per invoice in your quietest, which is the opposite of what most occasional and seasonal billers need. The flat fee never appears as a per-invoice number on the pricing page.

• →Subscription math: a Rs. 500-a-month plan plus one invoice that month is Rs. 500 for that invoice. Make none, you still pay Rs. 500.
• →Pay-per-use math: Rs. 9 buys one clean invoice. A month with zero invoices costs zero. The per-invoice price never drifts against your usage.
• →For people who genuinely run on documents (startups, freelancers, designers, event managers, subscription businesses), corporate bulk keeps the per-document price fair as volume grows instead of metering it through a monthly seat.
• →This is a pricing-structure difference, not a feature one. The suites are a fit for ongoing accounting; pay-per-use is a fit for occasional billing.

Every paid plan has a break-even point: the number of invoices it takes before its price works out to Rs. 9 each. Below that count, paying Rs. 9 only when you need a document is cheaper, and you commit to nothing in the months you bill nobody.

The table reads each paid plan at its lowest published tier and the total invoice count it takes to match Rs. 9 each. These prices are before 18% GST, so the real break-even is even higher than the count shown. For the annual subscriptions the fee recurs every year, so the count resets each year you keep the plan. Verify current terms before relying on them.

• →The fee is fixed; your billing is not. Zoho Books Standard costs Rs. 8,988 a year whether you raise 12 invoices or 999, so the price only works out to Rs. 9 each once you clear about 999 invoices.
• →A one-time licence front-loads the cost. TallyPrime Silver at Rs. 22,500 takes about 2,500 invoices before it matches Rs. 9 each, before counting the 18% GST on top.
• →All these prices are before 18% GST, so each break-even count is conservative; the real number of invoices needed is higher.
• →Pay-per-use commits nothing up front: Rs. 9 buys one invoice, there is no fee, and nothing to break even against.
• →High-volume billers who run on documents are a different job; for them, corporate bulk keeps the per-document price fair as volume grows.

There are two honest ways a tool earns: it charges you money, or it monetises attention and data. A genuinely free, ad-supported tool sits in the second group by design. A handler of your GSTIN, buyer names, and invoice amounts is exactly the kind of tool where that trade is worth reading before you use it.

• →The model: free, ad-supported tools carry ad-network code, and ad networks place cookies and tracking to target and measure ads. That is the cost that does not show up as a price.
• →Our position, stated flatly: hrareceipt.in runs no ads and stores nothing. The invoice is generated in your browser and never transmitted to a server, so your GSTIN and buyer data are not logged.
• →The Rs. 9 is the reason that holds: a tool paid by the user does not need ads or data resale to survive, which keeps the DPDP Act 2023 processing question off the table entirely.
• →Where the tool runs in the cloud or behind an account, your GSTIN, buyer names, and invoice amounts sit on their servers, under their privacy policy, not with you. With a browser-only tool the data never leaves your device.
• →Read each tool's own funding line and where it stores your data. A tool can be free or ad-free; the funding model decides which.

If your job is ongoing accounting, inventory, or filing GSTR-1 from the tool, a full suite fits that job and hrareceipt does not. hrareceipt is built for the opposite job: one clean invoice, fast, with nothing to set up, nothing to subscribe to, and nothing handed to a server.

• →No account, no app: you fill the fields and download. Auto CGST/SGST/IGST split, GSTIN format check, and HSN/SAC codes are built in.
• →Pay-per-use, not subscription: Rs. 9 buys one invoice; there is no monthly fee for a per-invoice cost to drift against.
• →No ads, nothing stored: the invoice is generated in your browser and never transmitted to a server, so your GSTIN and buyer data are not logged.
• →It does not do recurring billing, inventory, multi-user roles, or direct GSTR-1 filing. Those are a different job; if that is your job, pick a suite.
• →It is built for traders below the registration threshold too: switch to a bill of supply if you are unregistered.

Single-purpose generators stop at the invoice PDF. hrareceipt.in built the compliance tooling around it, so the same no-signup, nothing-stored workflow covers the documents and checks that sit next to a GST invoice.

• →Bill of supply: generated for composition-scheme and unregistered dealers who cannot issue a tax invoice, which not every generator does. See when a bill of supply replaces a tax invoice.
• →HSN/SAC lookup: find the right HSN or SAC code for a line item, since Rule 46 requires it on the invoice above the turnover threshold.
• →Section 269ST checker: test whether a cash receipt breaches the Rs. 2 lakh cash-limit before you accept it, with no data leaving the browser.
• →PDF tools: merge, split, compress, and convert invoices and statements at pdf.falcon.enterprises, browser-only and free, the same privacy posture.

Any tool you pick must still produce a Section 31 tax invoice carrying the Rule 46 fields, or your business buyer cannot claim input tax credit under Section 16.

• →You file your own GST and want one tool for invoicing plus returns: Zoho Invoice or ProfitBooks.
• →You run a shop counter with stock and staff: myBillBook or Vyapar (paid desktop tier).
• →You want a quick free web invoice and do not mind an account: Refrens works. The Vyapar web generator works too, but asks for your name and phone number before it downloads or prints, and adds "Powered by Vyapar" to the bill.
• →You bill occasionally or seasonally and do not want a subscription metering you: hrareceipt.in at Rs. 9 per invoice.
• →You need one clean GST invoice now, no account, no ads, nothing stored: hrareceipt.in.
