How to make an invoice
- Enter your business details once: name, address, phone and state. If you are registered under GST, tick "Registered under GST" and enter your GSTIN. These details are saved on your phone for next time.
- Fill in the customer. For a walk-in sale you can leave the name empty ("Cash customer"). Choose the place of supply: the customer's state.
- Add the items with quantity, unit, rate and GST rate. HSN/SAC codes are optional but recommended on GST invoices.
- Check the total on the right. GST, discount, round-off and the amount in words update as you type.
- Download the PDF or share it on WhatsApp. The invoice is saved in "Saved invoices", and the next one automatically gets the next number.
Tax invoice or simple bill?
- Registered under GST: the tool makes a Tax Invoice with your GSTIN, GST rate per item and the tax split.
- Not registered: untick the box and you get a plain Bill without any tax. Businesses that are not registered cannot charge GST.
- Composition scheme dealers cannot charge GST either; their document is called a "bill of supply".
CGST + SGST or IGST?
GST depends on where the goods or services go:
| Customer's state | Tax charged | On ₹1,000 at 18% |
|---|---|---|
| Same state as yours | CGST 9% + SGST 9% | ₹90 + ₹90 |
| Another state | IGST 18% | ₹180 |
The total tax is the same either way. Choose the right place of supply and the tool splits it for you. If you type the customer's GSTIN, the state is picked from its first two digits.
What a GST tax invoice must show
- Your name, address and GSTIN
- An invoice number of up to 16 characters (letters, digits, "-" or "/"), unique within the financial year, and the date
- The customer's name and address, and their GSTIN if they are registered
- A description, HSN/SAC code, quantity and value for each item
- The GST rate and amount (CGST/SGST or IGST), and the place of supply
- The signature of the supplier or an authorised person
This tool covers all of these. Businesses with a turnover above ₹5 crore must also issue B2B invoices as e-invoices with an IRN from the government portal, which this tool does not do.
Frequently asked questions
Is this invoice valid for GST?
Yes, if you enter your correct GSTIN, the right GST rates and HSN/SAC codes, and sign it. The PDF contains everything a tax invoice needs. Always check the GST rate for your goods on the official CBIC portal.
How does the invoice number increase automatically?
Each new invoice you download or share moves the counter to the next number, keeping your prefix and zeros: INV-009 is followed by INV-010. You can also type any number yourself.
Where are my invoices saved?
In "Saved invoices" on this page, only on this device. Nothing is uploaded. Download a backup regularly, and use "Export to Excel" to get a list of all invoices.
Can I give a discount?
Yes. Enter it in "Discount on total". It is spread over the items, so GST is charged on the discounted price, as the rules require when the discount is shown on the invoice.
Can I make the invoice in Marathi or Hindi?
Yes. Switch the page to मराठी or हिंदी at the top: the PDF headings and the amount in words follow the page's language.
