Lift AOV without losing the cart.
The pay step is the highest-intent moment in the entire funnel. Surface the right add-on, the right code, the right shipping nudge — and watch AOV move without slowing the customer down or breaking native flow.
What this category really does for you.
Most “AOV optimisation” happens at the cart — banners on the product page, sidebars on the cart drawer. But conversion peaks at checkout: the buyer has decided to buy, their card is out, friction tolerance is at its lowest. A relevant Upsell, a visible discount Coupon, a clear path to Free Shipping — each one converts dramatically better at this stage than the same trigger anywhere upstream. The blocks in this category are designed to compound: small lifts that stack into a material AOV difference within a week.

Stuck-at-threshold carts
Carts that consistently land just under your free-shipping threshold. Shipping Progress Bar + a small-AOV Upsell turn “almost” into “added”.
Abandoned-cart recovery
Returning from an abandoned-cart email? Coupon List surfaces the recovery code automatically — no copy-paste, no closed-tab loss.
High-margin stores
If you have room in unit economics, Shipping Protection plus a curated Upsell is the AOV-bumper that pays for itself within a single billing cycle.

Ask support-
How big is the AOV lift, really?
From real merchant data: +3–6% on AOV with a single block (Shipping Progress Bar is the most reliable). +8–11% when three booster blocks compound. Lower bound, not best case.
-
Won't more blocks slow the checkout down?
Every block is server-rendered into Shopify's checkout, no extra fetch on render. Three boosters add <30ms typical render time.
-
Are Conversion Boosters separate from upsell apps?
Yes. Most upsell apps work post-purchase (after the customer pays). These blocks work IN-checkout — at peak intent. Different stage, different attach rate.

Trust & Social Proof
The customer reached checkout — they almost trust you. Trust & Social Proof blocks close the gap: badges, payment icons, live reviews, and shipping protection. The smallest investment with the largest measurable lift.
