How to Make a GST Invoice in 2026
A GST invoice should be easy for your client to understand and easy for your accountant to verify.
In 2026, small businesses need GST billing that is simple enough for daily use but accurate enough for monthly compliance.
Basic GST invoice fields
A GST invoice usually needs:
- supplier name, address, and GSTIN
- unique invoice number
- invoice date
- recipient name and GSTIN, if registered
- description of goods or services
- quantity
- taxable value
- GST rate
- GST amount
- total invoice value
CBIC's GST invoice rules describe the key particulars required on tax invoices.
Keep GST simple in daily billing
For many small businesses, GST billing should not feel like tax filing.
The invoice screen should answer four questions:
- Who is the client?
- What did you sell?
- What is the taxable value?
- What is the final payable amount?
Smart Dhandha keeps GST as one simple tax field in the invoice flow, instead of forcing small teams to think about tax tables while billing.
Discount before GST
For clean billing, discount should reduce the taxable value before GST is calculated.
Example:
- Service value: Rs. 10,000
- Discount: 10%
- Taxable value: Rs. 9,000
- GST is calculated on Rs. 9,000
This is easier to explain to clients and keeps reports cleaner.
Composition GST businesses
Composition GST businesses should not collect GST from customers.
CBIC composition rules say a composition taxable person should mention that they are not eligible to collect tax on supplies on the bill of supply. See the official composition rules.
In Smart Dhandha, composition mode hides GST controls and can show the required composition note.
Non-GST businesses
If the company is not tax registered, the invoice should not show GSTIN, GST rate, or GST total.
This keeps the invoice honest and avoids confusing clients.
