Add a service upgrade, bonus session, annual plan, extra product, or premium version while the purchase is still fresh.
No second checkout to rebuild.

Offer sequences for more than one path.
Chain multiple offers together so each accept or decline can lead to the next best step.

Logic-based flows
Route each buyer through the offer that makes sense.
Use purchase behavior, selected options, or the current response to decide what the customer sees next.
Checkout add-ons
Add order bumps before the customer pays.
Not every offer needs a post-purchase page. Add a checkbox-style bump directly to checkout for low-friction add-ons, bonuses, or related products.
