Upsell
An extra, usually higher-priced offer shown right after a purchase to increase how much each buyer spends.
An upsell is an additional offer presented to someone who has already decided to buy, usually right after the first purchase and usually at a higher price. It is how a $17 front-end product can turn into a $200 transaction.
Front-end product $17

Upsell 2 $197
The reason upsells are everywhere is simple math. Winning a new buyer is the hard, expensive part. Once someone has their card out and trusts you enough to buy, selling them more is far cheaper than finding another buyer. That extra revenue often funds the ads that brought them in.
Upsells are not inherently a trick. A good upsell offers something a buyer genuinely needs to get more from what they just bought, such as a tool that saves real time. A bad upsell holds back part of what should have been in the first product, so the front-end feels incomplete until you pay again.
The number an upsell is designed to move is your average order value. Its cheaper cousins are the order bump and, if the buyer says no, the downsell.
