How to create a GST invoice in Vyapar

Once your items and customers are set up, a GST invoice in Vyapar takes under a minute. Vyapar fills in the customer's address, works out the place of supply, applies the right GST and splits it into CGST and SGST (or IGST) on the printed invoice.

Before you start

  • Your business details and GSTIN added (see the business details guide).
  • Items saved with HSN code and GST rate, and the customer saved as a party. You can also add them from the invoice screen.

1Click + Add Sale

On the Vyapar home screen, click the red + Add Sale button at the top. You can also use Sale > Sale Invoices in the sidebar. Close any tip pop-ups that appear the first time.

3Check address and state of supply

Vyapar fills in the phone number, Billing Address and the customer's balance, and sets State of supply from the customer's state. The invoice number and date are filled automatically.

Tip: If the State of supply is your own state, GST is split into CGST + SGST. For another state Vyapar charges IGST.

4Add the item

Click the first row under ITEM and type part of the item name. The list shows sale price, purchase price, stock in hand and location. Click the item to add it.

Good to know

  • Vyapar may send an automatic SMS to the customer when you save. Control it in Settings > Transaction Message.
  • Use Cash mode for walk-in customers without saving them as parties.
  • Save an invoice as a draft in a tab (+ at the top) to bill another customer and come back later.
  • Edit or delete an invoice from Sale > Sale Invoices; Vyapar keeps an audit trail of changes.

Questions people ask

How do I make a GST bill in Vyapar?

Click Add Sale, choose the customer, add items with quantity, check the GST and total, enter any amount received and click Save. Vyapar then shows the tax invoice to print or share.

How does Vyapar decide CGST/SGST or IGST?

From the State of supply. If it matches your business state, tax is split into CGST and SGST; otherwise IGST is charged.

Can I give a discount on a Vyapar invoice?

Yes. Enter a discount % or amount on each item line, or a discount on the whole invoice.

How do I share a Vyapar invoice on WhatsApp?

After saving, click WhatsApp in the Share Invoice panel of the preview. You can also share later from the invoice list.

Is the invoice valid without a GSTIN?

Businesses that are not GST registered should issue a bill of supply instead of a tax invoice; Vyapar supports both.
