Pricing checklist before you list a product

Answer these twelve questions on paper. If you cannot answer one, you are not ready to set the price.

  1. What does one unit cost, delivered to you? Include transport and any tax you cannot claim.
  2. Which GST or sales tax applies? Ask the tax authority or an accountant.
  3. What is the price without tax? That is your sale value. Use the GST calculator.
  4. What are the platform fees for this category? Write each one from the official page.
  5. What does it cost to ship one order, packed? Weigh it, then check the fee.
  6. What is your packaging cost per order?
  7. What will it cost to get an order? Ads, free samples, time.
  8. What is the likely return rate? Use similar products as a guide, then see returns.
  9. What margin do you need? Use the target price page.
  10. How many units must you sell? See break-even.
  11. How much money will be tied up? See cash flow.
  12. What will you do if the price falls? Decide your floor before a price war starts.

Print this page or save it, and fill it for each new product. A product that fails three questions is usually not worth listing.

Common questions

How often should I redo these sums?

Whenever a fee or a cost changes, and at least every quarter. Marketplace fees and shipping rates change more often than most sellers notice.
