3Check GST type and state

On the GST & Address tab, Vyapar sets GST Type to Registered Business - Regular and fills the State from the GSTIN. For a walk-in customer without GSTIN, leave it as Unregistered/Consumer and pick the state.

Tip: The party's state decides CGST + SGST (same state as you) or IGST (other state) on invoices.

4Add the billing address

Type the Billing Address and click the small blue Save under it. Click Enable Shipping Address if goods go to a different address.

Enter an Email ID if you want to email invoices and statements to this party.

6Click Save

Click Save, or Save & New to add the next party. Opening balance and credit limit are on the Credit & Balance tab (see the related guide).

7See your parties

Vyapar shows New party saved successfully. The party list on the left shows each party's balance: green means they owe you, red means you owe them. Click a party to see its details and transactions.

Good to know

Suppliers are added the same way; their balance shows in red when you owe them money.
Import many parties at once from Excel, or from your phone contacts in the mobile app.
Keep party names unique; two parties called Sharma make reports confusing.

Questions people ask

How do I add a customer in Vyapar?

Go to Parties > Party Details, click Add Party, enter the name, GSTIN, phone and address, and click Save.

Is there a separate screen for suppliers?

No. Customers and suppliers are both parties in Vyapar; add them from the same Add Party window.

Is GSTIN compulsory for a party?

No. Leave it empty for consumers and unregistered businesses. Add it for registered businesses so their invoices appear as B2B in GSTR-1.

Why did Vyapar change the GST type by itself?

When you enter a GSTIN, Vyapar sets the type to Registered Business and fills the state from the first two digits.

Where do I enter what a customer already owes?

On the Credit & Balance tab, as the opening balance with To Receive selected.
