Pharmacy Invoice Format (GST) – Retail & Wholesale Samples
A pharmacy invoice is a legal document detailing medicines sold, quantities, and prices. In India, it is mandatory for GST-registered pharmacies to issue a tax invoice that includes specific fields like batch number, expiry date, and GSTIN.

Mandatory GST Details in Pharmacy Invoices (India)
Under Indian GST law, every registered pharmacy must issue a "tax invoice." For B2B (wholesale) transactions, this must include the buyer's GSTIN. For B2C (retail) sales, it's optional unless the customer requests it.
A crucial compliance requirement for pharmacies is the inclusion of the **Batch Number** and **Expiry Date** for every drug sold. This is mandated by both the Drugs and Cosmetics Act and GST rules. Maintaining a sequential invoice number series for each financial year is also a strict requirement for GST compliance and audits.
