What an Invoice Must Include
A proper invoice tells the customer exactly what they bought, how much it cost, and how to pay — and it gives you a record for your own books. At minimum that means your business name and contact details, the customer's name, a unique invoice number, the date, a line-by-line list of what was sold with quantity and rate, and a clear total. If you're registered for GST, a few more fields become required: your GSTIN, the tax rate and amount for each item, and the place of supply, since that determines how the tax is split.
This generator builds all of that automatically as you fill in the form, and updates the live preview on the right so you can see exactly what your customer will receive before you download it.
GST vs Non-GST Invoices, in Simple Words
If you haven't registered for GST, you simply invoice the plain amount — no tax lines, no GSTIN, just items and a total. Once you're GST-registered, every invoice needs to show the tax separately from the price, using the rate that applies to each item (0%, 5%, 12%, 18% or 28% are the common slabs). This tool switches between the two modes automatically based on whether you've entered a valid GSTIN — leave it blank for a simple invoice, or fill it in to unlock GST fields throughout the form.
CGST + SGST vs IGST: same state or different state
When your business and your customer's place of supply are in the same state, the GST is split into two equal halves — CGST (central) and SGST (state) — each charged at half the total rate. When they're in different states, the full amount is instead charged as one tax, IGST, at the combined rate. You don't need to calculate this yourself: just set your state in Step 1 and the customer's place of supply in Step 2, and the invoice works out CGST/SGST or IGST automatically.
Getting Paid Faster with a UPI QR Code
Adding a UPI QR code to your invoice removes a whole step for the customer — instead of typing in your UPI ID by hand (and risking a typo), they scan the code and the amount, your name and a reference number are filled in automatically. Enter your UPI ID in Step 4 and this generator builds a scannable QR code for the exact invoice total, shown in the preview and included in the downloaded PDF.
Frequently Asked Questions
How do I make an invoice for free?
Fill in your business details once (they're remembered for next time), add your customer and items, and download a PDF — no signup, no payment, and nothing is uploaded to a server. Everything happens in your browser.
What details must an invoice have in India?
At minimum: your business name and address, the customer's name, an invoice number and date, a description of goods or services with quantity and rate, and the total amount. If you're GST-registered, your GSTIN, the customer's GSTIN (for B2B), the place of supply, and GST charged must also be shown.
When do I charge CGST/SGST vs IGST?
If your business and your customer's delivery address (place of supply) are in the same state, you charge CGST + SGST, split equally. If they're in different states, you charge IGST instead, at the same total rate. This tool works that out automatically from your state and the customer's place of supply.
Can I make an invoice without GST registration?
Yes — leave the GSTIN field blank and this tool generates a plain (non-GST) invoice with no tax columns, just your items, totals and the amount due.
Can I add a UPI QR code to my invoice?
Yes — enter your UPI ID in Step 4 and a scannable QR code for the exact invoice amount is added to the preview and the PDF automatically.
