GST Invoice Template: download in Excel and Word Format

Invoicing is like creating a receipt for buying something. Getting it right is super important to avoid mistakes in details like who’s selling, who’s buying, and where things are going. It’s also important for calculating costs, taxes, discounts, and more. Businesses should be extremely cautious about proper invoicing in conditions of GST with a whole number of tax rates and types.

Get this: one tiny mistake in your invoice, like misspelling a buyer’s name or goofing up on the tax calculation, can snowball into a nightmare. It can result in the taxman coming, and you’re left scrambling to fix things.

But here’s the kicker: proper invoicing isn’t just about avoiding trouble; it’s about saving money too. You can claim back the GST you’ve already paid on your business expenses.

In this article, we’ll explain the basics of invoicing under GST and offer you a free ready‑to‑use template of the GST invoice.

What GST Regime Means

In simple terms, the GST regime refers to the system of taxation that India adopted in 2017, known as the Goods and Services Tax. Under this regime, various indirect taxes like VAT, luxury tax, service tax, purchase tax, and others were replaced by a unified tax called GST.

This change was aimed to simplify the tax structure, reduce tax evasion, and make the tax system more efficient. The GST regime classifies goods and services into different tax slabs, ranging from 0% to 28%, based on their nature and other factors. This system has brought about significant changes in how taxes are applied and has impacted businesses and consumers across the country.

GST is a tax collected on goods and services at each stage of the supply chain, from the manufacturer to the consumer. The rules determine how GST is calculated, collected, and paid. They also outline the registration process for businesses, the filing of returns, and the invoicing requirements.

Understanding these rules is important for businesses to comply with the law and ensure smooth operations.

Taxes under Goods and Services Tax

There are several types of GST under the Indian taxation system. These include:

  • Integrated Goods and Services Tax (IGST)
  • State Goods and Services Tax (SGST)
  • Central Goods and Services Tax (CGST)
  • Union Territory Goods and Services Tax (UTGST)

CGST and SGST are levied on intra‑state supplies, where the revenue is shared between the central government and the state government. IGST is applicable to inter‑state supplies and is collected by the central government.

UTGST is similar to SGST but is applicable in union territories. Each type of GST has its own set of rules and regulations, ensuring a smooth taxation process across the country.

What Is GST Invoice

A GST invoice or a GST bill is a document that is used to record the sale of goods or services under the Goods and Services Tax (GST) system in India. The GST invoice plays a crucial role in the GST regime as it serves as proof of the sale for both the seller and the buyer, and is essential for claiming input tax credit.

GST Invoice Format

All GST Invoices must include the following information:

Mandatory FieldDescription

Invoice number and date

Unique number and date of the invoice

Seller details

Name, address, phone number, and other details of the seller

Customer name

Name of the customer purchasing the goods and services

Billing address

The billing address of the customer


GST Identification Number of both seller and customer

Place of supply

In the overwhelming majority of cases this is the buyer’s registered business address or the location where the goods or services are delivered.

Item details

Description of the goods and services, unit prices, quantities, amounts

HSN/SAC codes

Harmonized System of Nomenclature codes for all goods and services mentioned in the invoice. The SAC code (Service Accounting Code) is a classification system used to categorize various services for taxation under India’s Goods and Services Tax (GST) regime. Similar to how the HSN code categorizes goods, the SAC code assists businesses in classifying the services they provide.

Taxable value and discounts

The value of the goods and services on which the taxes are calculated after deducting any discounts

Rate and amount of taxes

Rate and amount of Central GST (CGST), State GST (SGST)/Union Territory GST (UTGST) for intra‑state transactions, or Integrated GST (IGST) for inter‑state transactions


Signature of the representative of the supplier

GST invoice rules

Who Must Issue GST Invoices

In India, the issuance of Goods and Services Tax (GST) invoices is a crucial part of the compliance framework under the GST regime. The following entities must issue GST invoices:

  1. Registered Taxable Persons: Any business or individual who is registered under GST and supplies goods or services is required to issue a GST invoice. This includes:

    • Regular Taxpayers: Businesses registered under the regular scheme must issue GST invoices for every sale of goods or services.
    • Composition Dealers: While composition dealers are not required to issue a tax invoice, they must issue a bill of supply. Composition dealers cannot charge GST on their sales; instead, they pay GST at a fixed rate on their turnover.
  2. Exporters: Businesses that export goods or services must issue a GST invoice, clearly mentioning that the supply is an export and hence zero‑rated.
  3. Input Service Distributors (ISD): An ISD must issue an invoice or a credit note for distributing the input tax credit to its units or branches.
  4. Reverse Charge Mechanism (RCM): When a business or individual is liable to pay GST under the reverse charge mechanism, they must issue a self‑invoice if the supplier is unregistered.
  5. E‑commerce Operators: E‑commerce operators facilitating supplies on behalf of other suppliers must issue an invoice when they are liable to collect tax at source (TCS).

Situations Where Invoices Are not Required

In some cases, issuing a tax invoice is not mandatory:

  1. Unregistered Individuals: Individuals or entities not registered under GST.
  2. Small Businesses: Small businesses with turnover below the threshold limit for GST registration (currently ₹40 lakhs for goods and ₹20 lakhs for services, subject to specific conditions and exceptions).
  3. Exempt Supplies: Supplies that are wholly exempt from GST or non‑GST supplies.

Overall, the requirement to issue GST invoices ensures transparency and proper accounting within the GST system, aiding both compliance and tax administration.

Time Limits for GST Invoice Issue

The GST law sets a specific time frame for issuing a GST invoice, which varies depending on the type of supply. For goods, it’s typically required before or at the time of delivery for a single supply, or before or at the date of payment or issuing an account statement. For services, the invoice must be issued within 30 days from the date of supply.

Obligatory Number of Copies of the GST Invoice

When issuing a GST invoice, businesses are required to provide multiple copies, depending on the nature of the transaction. These copies ensure transparency and accountability in transactions, facilitating smoother operations and compliance. The following table shows what party of the transaction should get the copy.

Supply of Goods

Supply of Services

Minimum Transaction Amount to Issue a GST Invoice

While GST mandates the issuance of invoices for most transactions, there is a minimum transaction threshold below which businesses are not required to issue invoices. A tax invoice is not required for transactions below INR 200 in two cases:

  1. If the recipient is unregistered
  2. If the recipient does not specifically request an invoice. If the recipient asks for it, an invoice must be provided.

However, at the end of each day, a consolidated or aggregate invoice should be prepared for all transactions below the threshold where a tax invoice was not issued. Businesses may also choose to issue invoices voluntarily for record-keeping and transparency purposes.

Difference between Invoice and GST Invoice

An invoice and a GST invoice serve similar purposes but differ in their scope and legal implications. While both documents detail the goods or services provided, a GST invoice includes additional information required for compliance with the Goods and Services Tax regulations. This includes the seller’s GSTIN (Goods and Services Tax Identification Number), the buyer’s GSTIN (if registered), the place of supply, the HSN (Harmonized System of Nomenclature) code for goods, and the SAC (Services Accounting Code) for services.

Additionally, a GST invoice clearly indicates the amount of GST charged on the transaction, which is essential for tax filing and claiming input tax credit. In contrast, a standard invoice may lack these specific details required by the GST regime, making it insufficient for businesses operating within the GST framework.

How to Create GST Invoice Template

It may seem hard but you can create and customize your own GST Invoice template without any significant complications. Let us guide you through the whole process of creation. We’ll start with the easiest steps.

Step 1: Create a New Spreadsheet

Go to Google Sheets and create a new spreadsheet. Name the spreadsheet so it’s easy to find when needed.

Step 2: Label Basic Fields

Label the first row with basic fields like Invoice Number and Invoice Date.

Step 3: Include Your Company Details

In the upper part of the spreadsheet, include your company’s name, address, GSTIN, and any other relevant information.

Step 4: Prepare Counterparty Details

Ensure there’s enough space in the document to fill in all the information for your counterparties.

Step 5: Add Details of Goods and Services

Include fields for details of goods and services, GST rates, amounts, discounts, and taxable value.

Step 6: Add Formulas for Calculations

Add formulas to calculate the total taxable value, tax rates, and total amount automatically. For example, you can use a formula like =Quantity*Unit Price for the taxable value.


  1. Click on the cell where you want the result to appear. This is usually the cell next to the values you want to multiply.
  2. Start the formula with an equals sign (=). This tells Google Sheets that you’re entering a formula.
  3. Click on the cell containing the quantity, type * (asterisk) to represent multiplication, and then click on the cell containing the unit price.
  4. Press Enter on your keyboard.

Google Sheets will calculate the total price by multiplying the quantity and unit price and display the result in the cell. You can use similar formulas to calculate taxes, discounts, and other values in your invoice.

Step 7: Format the Document

Draw borders to separate important sections and make information easier to digest.

Step 8: Make a Copy for Future Invoices

Make a copy of this sheet whenever you need to create a new invoice. This way, you won’t have to clear the data every time and avoid confusion.

A handy tip: Enter Sample Data and Apply More Formatting

Fill in a few rows with sample data to visualize how the invoice will look. Format the cells to make the invoice easy to read and professional. You can use bold text for headings and align text to the left or right as needed.
