What is Inclusive GST?

Inclusive GST means the tax is already included in the displayed price. When you see ₹1,180 on a product, that amount contains both the base price and the 18% GST. Customers pay the total shown without any additional charges.

Used in: Retail stores, restaurants, hotels, and e-commerce platforms where customers expect transparent pricing.

What is Exclusive GST?

Exclusive GST means the displayed price is before tax. GST is calculated separately and added on top. So ₹1,000 base price + 18% GST (₹180) = ₹1,180 total. The tax is shown as a separate line item.

Used in: B2B invoices, wholesale, professional services, and business-to-business transactions.
