What Is a GST Invoice?

A GST invoice is a document generated by a seller of a particular product or service and shared with the buyer. This is done once the transaction has been completed and the buyer has accepted the product or service after delivery. It is a legally binding way for the seller to establish that the transaction has been completed satisfactorily and the payment is now due. The GST invoice contains all the details of the specific transaction along with the details of the applicable taxes.

There are many formats that a GST invoice can be created in and used, such as a GST invoice format in Excel or a GST invoice format in word. Without this document, a seller cannot legally expect the buyer to make the payment for the respective product or service.

What Should be Included in a GST Invoice?

As an SME business owner, it is crucial you ensure that all the necessary elements are included in your GST invoice so that you can avoid unnecessary payment delays. Typically, a GST bill format will include:

  • The buyer details: The company name of the buyer along with the corporate address.
  • The seller Details: The company name of the seller along with the company address.
  • A unique identifier: A unique identification number or an alphanumeric code.
  • Date of invoice: The date of issuance of the GST invoice.
  • Item description: A brief description of the product or service that has been provided.
  • Quantity details: A clear mention of the number of products that were purchased.
  • The price point: The agreed-upon price per unit.
  • The taxes applicable: Depending on the nature of the purchase, the accurate amount of taxes.
  • The total amount: A calculated total of the amount due as a function of the number of units purchased and the price per unit, plus taxes.
  • Payment dates: The expected due date by which the payment should be made
  • Required signatures: Duly signed by the authorized signatories to make it formal and legally binding.
  • You can first create a sample GST invoice format using automated software and choose the one that best suits the nature of your business.

    How to Make an Invoice?

    Whether you are choosing to make use of a GST invoice format in excel or a GST tax invoice format in Word, you just need to keep a few things in mind when making your invoice:

    • Legibility

      Make sure that the font style and sizes that you use are appropriate and make it easy to read. The company details of both the buyer and the seller are to be mentioned clearly.

    • Transparency

      The prices agreed upon during the negotiation should reflect on the invoice as well. Make sure you fill out the prices per unit as well as the total amount due, duly calculated with applicable taxes.

    • Specifications

      Names and descriptions of the items that have been purchased should be mentioned.

    • Dates and Timelines

      Your GST invoice should draw attention to the due date for payment and any other relevant timelines.

    How to Create GST Bill in Excel and Word?

    A GST tax invoice format can be found in both Microsoft Excel as well as Word. Both these are tools designed in a manner that you can easily make a tax invoice format under GST using either. To begin with, it is important to understand the reason why you are creating an invoice format in GST. The purpose of this document is to formally and legally establish the fact that the transaction in question has been completed. That means the product or service has been delivered, evaluated by the buyer, and accepted in the condition that it has been received. The buyer has acknowledged the same and you can now raise the invoice and expect the payment. To create a GST bill in Excel or Word, create a table with columns for details including, item name, quantity, price per unit, GST rate, and total. In the first row, enter the column headings and format them appropriately, followed by subsequent details

    What Are the Different Types of Invoices?

    As an SME business owner, you will need to be aware of all the different invoice types that exist and you may have to make use of them. Here's a look at some of the most common types:

    • A Tax Invoice

      This is a type of invoice that is required by law if you are operating at a certain scale and are GST compliant. It needs to have all the applicable tax details for your type of business. These differ across transactions that happen within the same state or if your products are being sold across state lines.

    • An Electronic or E-invoice

      With the coming of the digital age, invoice management has been transferred online. An e-invoice is an electronic document that exists only digitally.

    • A Pro Forma invoice

      An invoice is usually raised after a sale has been completed. On the other hand, a pro forma invoice is issued once the terms and conditions have been agreed upon verbally. This is not a legally binding document, but rather a way for the seller to get written confirmation from the buyer on the details of the deal.

    • A Commercial Invoice

      This type of invoice comes into play when products are exported internationally and the customs authorities need to be made aware. Typically used by shipping companies, a commercial invoice needs to include details of the shipment and the buyer and seller.

    Non-GST Invoice Format

    In case your business operates at a small scale and you are currently not required to be GST compliant, you can also opt for a non-GST invoice format. This can be made like a GST bill format in Word or a GST bill format in Excel or another format that suits your specific needs better. A non-GST invoice format does not have any such mandatory requirements, unlike a GST invoice format. However, since the purpose of an invoice is to establish that a transaction has been completed successfully and the seller is now due to be paid, it needs to look professional. If you need simple, professional invoice templates, simply try TranZact.
