The best moment to sell something to someone is right after they've already bought. At that moment, the psychological barrier is already down, the credit card is already out, and the brain is in "buying mode".

Upsells and order bumps leverage exactly this moment.

Difference between order bump and upsell

Order Bump: offer presented on the checkout page, before purchase completion. It's a checkbox — no new purchase decision required, just "add this too".

Upsell: offer presented after purchase is complete, on the thank-you page or an intermediate page.

Order Bump: how to make it work

  • Low price: 10-30% of the main product price
  • Complementary: adds immediate value to the existing purchase
  • One line of copy: the benefit must be clear in 10 words
  • Struck price: shows real value vs special price

Average conversion for well-positioned order bump: 20-40% of buyers accept it.

Upsell: how to structure it

  • Logical: the natural next step after the just-made purchase
  • Increased value: offers more results, faster, with less work
  • One click: purchase must happen with a single click
  • Real urgency: only if it's true
