GST Invoice for Clinics in India: Format, Rules & Software (2026)
How to generate GST-compliant invoices at your clinic — HSN codes for consumables, exempt consultations, credit notes, and software automation tips.
GST invoicing at clinics confuses many doctors because consultations are often exempt while medicines, implants, and rentals attract tax. Your invoice must separate exempt and taxable lines clearly.
Invoice essentials
- Clinic GSTIN on all taxable supplies
- HSN codes for consumables and pharmacy items
- Correct tax rate — typically 5% or 12% on medicines, 18% on some equipment
- Patient name, date, and itemised breakup
- Credit notes for refunds and adjustments
