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.

Upsell
Show Shopify’s Related or Complementary product recommendations, or products you select yourself. Buyers can add them without leaving checkout.
See the block Conversion BoostersFeatured Upsell
A single hero recommendation — big image, full details, one prominent Add button.
See the block Conversion BoostersQuick Add Upsell
Dense product rows — image, title, price, Add. Paging only when it's needed.
See the block Conversion BoostersPromo Banner Upsell
Your banner image up top, curated recommendations directly beneath it.
See the block Conversion BoostersShipping Progress Bar
A live bar showing how close the cart is to free shipping — the classic AOV lift.
See the block Conversion BoostersProgress Bar
Track subtotal, quantity or specific products against a ladder of milestones.
See the block Conversion BoostersStep Indicator
Show the current step and a progress bar on three-page checkout. Steps are detected automatically. The block stays hidden on one-page checkout.
See the block Conversion BoostersCoupon List
Show discount codes you enter, with an Apply button. Shopify checks eligibility when a buyer applies a code; the list does not automatically hide ineligible codes.
See the block Conversion BoostersShipping Protection
Let buyers add an optional protection-fee product to their order. Your store handles the protection service and claims.
See the blockThree patterns that work.
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
Enter your recovery discount under Manual Coupons to display it in checkout. The block does not automatically identify abandoned-cart returners or retrieve their recovery codes.
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?
These blocks run through Shopify Checkout Extensibility. Test your checkout on desktop and mobile after adding them.
-
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.
Browse the rest.
Trust & Social Proof
The customer reached checkout — they almost trust you. Trust & Social Proof blocks close the gap: badges, payment icons, and customer reviews you enter yourself. The smallest investment with the largest measurable lift.
See the category 02Custom Fields
Shopify's native checkout gives you name and address. Everything else — gift messages, B2B PO numbers, delivery dates, special instructions, age verification — happens here. Eight field types, visibility conditions for each saved block, and no theme code needed.
See the category 04Information & Messaging
Reassure on shipping. Answer common questions before buyers pay. Compose any message with headings, dividers, cards, and rich text. The Information & Messaging blocks let you address last-second doubts without sending the buyer to a popup or a separate page.
