Making a Valid GST Invoice

If you are a registered business in India, issuing a proper Tax Invoice is mandatory for B2B and B2C sales. Using our free online invoice generator, you can easily comply with the latest CBIC rules.

Supplier & Buyer Details
Unique Invoice Number
Date of Issue
HSN / SAC Codes

Proforma vs. Tax Invoice

A Proforma Invoice is an estimate or a "Kachha Bill". You send it to a customer before the goods are delivered to request payment. It cannot be used to claim Input Tax Credit (ITC).

A Tax Invoice is the final, legally binding bill generated after the sale is confirmed.

Frequently Asked Questions

Is this invoice generator truly free?

Yes, 100% free. There are no watermarks (unless you want to add your own logo) and no limits on how many PDFs you generate and download.

Where is my data saved?

For this free web tool, no data is saved on our servers. The invoice is generated locally in your browser to protect your business privacy. Once you refresh the page, the data clears.

Can I send this to my CA for GST filing?

While you can send the PDF to your CA, manually entering PDFs into accounting software takes time. We recommend downloading the KOSH PC App which automatically exports all your bills into a neat Excel GSTR-1 format for your CA.
