Compliant Invoices, the Right Format & a Fast Generator

Create GST-compliant invoices in seconds — auto CGST/SGST/IGST, correct HSN/SAC mapping, the right GST invoice format, and GSTR-1/GSTR-3B-ready data, powered by LEDGERS.

What Is a GST Invoice and When Is It Required?

A GST invoice is the tax document a registered supplier issues for a taxable supply, showing the GST charged on it. It is the single most important record in GST invoicing, because the buyer uses it to claim input tax credit.

One wrong field can block your buyer's input tax credit or trigger a return mismatch. Good GST billing software applies the correct invoice format every time, calculates tax automatically, and keeps each invoice ready for filing.

A GST invoice is required whenever a registered business makes a taxable sale. Timing matters too — for goods, it must be issued on or before delivery or removal; for services, within 30 days of supply. When GST is charged you issue a tax invoice; when no GST applies (a composition dealer or an exempt supply) you issue a bill of supply instead. A tax invoice carries GST; a bill of supply does not.

At N D Savla & Associates, we provide complete GST invoicing solutions powered by LEDGERS — error-free, professional invoices that connect directly with our GST Registration, GST Return Filing, and Indirect Tax Services, so your billing and compliance run as one system.

Mandatory Fields in a GST Invoice

A valid GST invoice format is not a design choice — the law prescribes the fields every invoice must carry. Get them right and your buyer claims credit smoothly; get them wrong and the invoice can be rejected.

Invoice Number & Date

A unique, consecutive invoice serial number and the invoice date on every GST invoice.

Supplier & Recipient GSTIN

Name, address, and GSTIN of the supplier, and of the recipient where registered.

HSN / SAC Code

HSN code for goods or SAC code for services — the code decides the GST rate, so it must be right.

Description & Quantity

Clear description, quantity, and unit of the goods or services supplied.

Taxable Value & Tax Split

Taxable value, GST rate, and the CGST, SGST, or IGST amount, split correctly for the supply.

Place of Supply & RCM

Place of supply, and whether tax is on a reverse charge basis — plus the supplier or digital signature.

How to Create a GST Invoice the Right Way

Open a fresh invoice and pull in your GSTIN automatically, add the customer and their GSTIN, enter each line item with its HSN or SAC code, set the GST rate, and let the generator split CGST and SGST for a local sale or apply IGST for an inter-state sale based on the place of supply. Finally, save and share. For exporters, the same flow handles zero-rated billing alongside an LUT, so export invoices stay compliant too.

Common Questions on GST Invoicing

What is a GST invoice and when is it required?
A GST invoice is a tax document a registered supplier issues for a taxable supply of goods or services, showing the GST charged. It is required whenever a GST-registered business makes a taxable sale. For goods, the GST invoice must be issued on or before delivery or removal. For services, it must be issued within 30 days of supply. A correct GST invoice lets the buyer claim input tax credit, which is why accurate GST invoicing matters.
What are the mandatory fields in a GST invoice?
The mandatory fields in a GST invoice include a unique consecutive invoice serial number and date, the supplier's name, address and GSTIN, the recipient's details, the HSN code for goods or SAC code for services, description and quantity, taxable value, the GST rate, and the CGST, SGST or IGST amount. A valid GST invoice format must also show the place of supply and, where required, whether tax is on a reverse charge basis.
What is the difference between a tax invoice and a bill of supply?
A tax invoice is issued when GST is charged on the supply, and it lets the buyer claim input tax credit. A bill of supply is issued when no GST is charged, for example by a composition dealer or on exempt goods. So the core difference between a tax invoice and a bill of supply is simple: a tax invoice carries GST, a bill of supply does not. Good GST billing software generates the correct document automatically.
How do I create a GST invoice?
To create a GST invoice, start from a compliant GST invoice format, add your GSTIN and the customer's details, enter each item with its HSN or SAC code, set the GST rate, and let the software split CGST, SGST or IGST based on the place of supply. Using GST invoice software removes manual errors, applies the correct tax automatically, and keeps every GST invoice ready for GSTR-1 filing.
Is a GST invoice mandatory for B2C sales?
Yes, a GST invoice is required for B2C sales too, though small-value rules apply. For supplies below Rs. 200 to an unregistered buyer, a tax invoice need not be issued for each sale unless the customer asks, but a consolidated invoice can be raised at day end. Above that, a proper GST invoice is mandatory. A GST invoice generator handles both B2B and B2C billing in one place.
