GST Invoice Generator

Make a GST invoice with GSTIN, state, and tax fields — free, in your browser, downloaded as a professional PDF. Defaults to 18% GST and ₹, both editable.

What a GST invoice needs to include

  • Your name, address, and GSTIN
  • A consecutive invoice number and the invoice date
  • The client's name, address, and GSTIN (for registered businesses)
  • Place of supply — the client's state decides CGST+SGST vs IGST
  • Description, quantity, and value of each service or item
  • The tax rate and tax amount charged

General information, not tax advice — GST rules depend on your registration, service category, and turnover. Confirm specifics with a professional.

Billing clients abroad?

Exports of services are treated differently under GST, and you will usually invoice in your client's currency. The generator supports USD, EUR, GBP and more — switch the currency and the invoice formats itself correctly. For the full picture, read our guide on invoicing international clients from India.

Frequently asked questions

Is this GST invoice generator free?

Yes — create and download unlimited GST invoices without an account or card. Free PDFs carry a small “Created with BillSlip.com” footer line.

Which GST fields does the invoice include?

Your GSTIN and state, your client's GSTIN and state, an itemized breakdown, and the GST rate and amount. That covers the fields a service invoice under GST is generally expected to carry.

What GST rate should I use for freelance services?

Most professional and IT services in India attract 18% GST, which is this page's default — but rates vary by service category, so confirm yours with the official rate schedule or a professional.

Do I need GST registration to invoice a client?

Not always — registration generally becomes mandatory past the annual turnover threshold (₹20 lakh for most services) or for certain inter-state supplies. If you are unregistered, invoice without charging GST and leave the GSTIN fields blank.
