Tax-exclusive: tax is added ON TOP of the base price (you enter the pre-tax price). Tax-inclusive: tax is ALREADY included in the amount (you enter the total and extract the tax).
What is GST in India? +
GST (Goods and Services Tax) in India has four slabs: 5% (essential goods), 12% (standard goods), 18% (most services), and 28% (luxury/sin goods).
What is VAT in the UK? +

How to back-calculate original price from GST-inclusive amount? +
Original Price = Total ÷ (1 + GST Rate/100). Example: ₹1,180 with 18% GST → Original = 1180 ÷ 1.18 = ₹1,000.
