AOVBooster places configurable upsell offers at three points in the buying journey: the cart, Shopify's native checkout, and the post-purchase page after an order is placed. Merchants choose which products, discounts, and widgets appear at each placement without writing code. Billing is usage-based through Shopify's Billing API, scaled to the revenue AOVBooster attributes to accepted offers, so the amount billed tracks the additional sales the app generates.

• Cart upsell widgets that recommend related products before checkout
• Checkout UI extension offers rendered in Shopify's native checkout
• Post-purchase offers with a variant picker shown after the order is placed
• Analytics dashboard breaking down revenue by placement
