GST Invoice Generator.

You only need a GSTIN if you intend to issue a formal "tax invoice", which is the document that lets your buyer claim input tax credit. If you are below the GST registration threshold, currently Rs 20 lakh of turnover for services and Rs 40 lakh for goods in most states, you are not required to register and instead issue a bill of supply with no tax charged. This tool handles both situations comfortably: set the GST percentage to 0 and the generated PDF shows a clean invoice with no tax line, which works as a bill of supply for an unregistered seller. Once you cross the threshold and register, simply enter your GSTIN and the applicable rate, and the tool produces a proper tax invoice with the tax split shown. If you are close to the threshold, track your turnover monthly, because registration becomes mandatory the moment you cross it and issuing tax invoices without a GSTIN is not permitted.

The split is automatic because Indian GST law requires it for intra-state supplies, where the seller and buyer are in the same state. In that case the total tax is divided equally between Central GST and State GST, so an 18 percent rate becomes CGST 9 percent plus SGST 9 percent on the invoice, and a 12 percent rate becomes CGST 6 plus SGST 6. The split is always exactly half and half; it is fixed by law, not a setting you can change. For inter-state supplies, where the buyer is in a different state, the same total instead appears as a single IGST line at the full rate, for example IGST 18 percent. The tool determines which treatment applies from the place of supply you enter, so you do not have to remember the rule. This split is one of the most common things small sellers get wrong by hand, so letting the tool compute it keeps your invoices compliant and your buyers input credit clean.

Not yet; logo upload is on the roadmap rather than in the current build, so for now the generated PDF uses a clean, text-only header showing your business name and details in a tidy layout. That keeps the invoice professional and perfectly valid, since a logo is a branding nicety rather than a GST requirement, your GSTIN, invoice number, date, line items and tax split are what actually matter for compliance. When we do add logo support, it will follow the same privacy-first approach as the rest of the tool: the image you choose will be processed entirely in your browser and embedded into the PDF locally, with nothing uploaded to any server. In the meantime, if you really want branded invoices today, you can open the downloaded PDF in a free editor and drop your logo into the header manually, though for most small businesses the clean text header is more than presentable enough to send to a customer.

No, your invoice data never leaves your browser. The entire tool runs client-side: the line items, amounts, customer details and tax calculations are all handled locally on your own device, and the PDF is generated in the browser using the jsPDF library. For convenience, your seller details, your business name, address and GSTIN, are saved to your browser localStorage so you do not have to retype them on every invoice; clearing your browser data wipes that store, and it is never transmitted anywhere. The only network request involved is loading the jsPDF library file itself from a CDN, and that request carries no invoice content, just a plain ask for the library code, the same as loading any website asset. This matters because invoices contain sensitive commercial and customer information, and keeping it on-device means there is no copy of your billing data sitting on someone else server to be leaked or breached. What you generate stays with you.

Not cleanly, because this tool is built for A4 invoices aimed at email and standard laser or inkjet printing, which is the format buyers expect for a tax invoice they will file. A thermal POS printer uses a narrow continuous roll, typically 58mm or 80mm wide, and an A4 layout simply does not fit that width; it would print squashed or run off the paper. Thermal receipts need a purpose-built template designed around the narrow roll, with a stripped-down layout, larger type and no wide tables. So for a retail counter that prints little till slips, this tool is not the right fit today. It shines instead for businesses that email PDF invoices or print full-page bills, freelancers, consultants, wholesalers, service providers and B2B sellers. If a dedicated 58mm or 80mm thermal mode would genuinely help your shop, let us know, because we will scope it as a separate template rather than trying to force the A4 design onto roll paper.

e-invoicing is a separate compliance step that this tool does not perform, because it requires a live integration rather than a generated PDF. Under the current rules, businesses above the notified turnover threshold, which has been lowered in stages to Rs 5 crore, must report each B2B invoice to the government Invoice Registration Portal, the IRP, which validates it and returns a signed Invoice Reference Number plus a QR code that then has to appear on the invoice. That round trip needs an authorised integration with a registered IRP or GST Suvidha Provider, typically built into proper accounting software or an ERP. This tool covers everything up to that point and is ideal for businesses below the e-invoicing threshold, which is the vast majority of small sellers. If your turnover has crossed the limit, you should move to an IRP-registered partner or e-invoicing-enabled accounting platform, since manually generated PDFs will not carry the mandatory IRN and QR and would not be compliant for your buyers.

You can, with one small manual step for now. A proforma invoice and a quotation are essentially the same line items and totals as a tax invoice but carry a different heading and are not a demand for payment, so the practical workaround today is to generate the document here and then change the heading label after download. Most PDF readers let you edit a text field, or you can open the file in a free PDF editor and relabel the header to "Proforma Invoice" or "Quotation" in a few seconds. This is handy when you want to send a customer a price estimate before confirming an order, or a proforma so a corporate buyer can raise a purchase order. To make this seamless, we plan to add a heading dropdown offering Tax Invoice, Proforma and Quotation in a future iteration, so the label is set automatically. Until then, the relabel takes under a minute and the calculations underneath remain identical.

Only partially, and the responsibility for the actual computation stays with you. Reverse charge is the situation where the buyer, rather than the seller, is liable to pay the GST to the government, which applies to specific notified supplies and certain transactions involving unregistered suppliers. For now, this tool lets you record a reverse-charge note in the description field so the invoice clearly flags that reverse charge applies, which is the disclosure your buyer needs to see. What it does not do is calculate the reverse-charge tax for you, because whether it applies, and at what rate, depends on the specific category of goods or services and the registration status of both parties, which vary widely by industry and buyer type. Getting that wrong has real tax consequences, so if you are dealing with reverse-charge supplies and are not certain of the treatment, confirm the exact handling with your chartered accountant before you finalise the invoice rather than guessing at it.
