Quick answer

Frequently asked questions
Is commission charged on the GST-inclusive price?
On most Indian marketplaces commission is calculated on the selling price including GST. Check your platform's current rate card.
Why does the calculator ask for return rate?
Returns cost shipping both ways and sometimes the product. Ignoring them overstates profit.
