Upsells and Order Bumps are great ways to maximize profit from your Offers during the checkout process.
The difference between an Upsell and an Order Bump is that an Upsell will appear after your customer completes their purchase and is used to advertise a related Offer.
An Order Bump will appear on the checkout page sidebar as a checkbox to add another product to their initial order, typically adding a product that complements the product in the checkout.
Upsell
An Upsell is used as a way to advertise another Offer after the initial Offer has been purchased. A user will complete the checkout flow and then be presented with a new page with the option to purchase another Offer.
Note: Add up to 10 upsells to your Offer checkout process.
Order bump
An Order Bump is used as a way to advertise another Offer on the checkout screen. A user will go through the checkout sequence and see a simple option to add another Offer to their checkout total.
