Checkout & Conversion — Build vs. Buy

Building gift options into the theme wins: one section writing cart attributes replaces a forever widget, and the gift fields land on orders you own.

Checkout & Conversion

One-page and express checkout tuning is a CUSTOMIZE call: tune the sanctioned checkout surface instead of fighting a flow you cannot replace.

Checkout & Conversion

Building a delivery date picker wins on Plus: the checkout-extension surface was designed for it, and the date flows into fulfillment, not an app dashboard.

Checkout & Conversion

Hiding, reordering or gating payment methods is a $3.99–$9.99/month app decision (verified Sep 2026); a custom function needs Plus and rarely pays back.

Checkout & Conversion

Overriding a bundle line's price, title and image with Cart Transform's lineUpdate works only on development stores or Shopify Plus; bundle apps cover the rest.

Checkout & Conversion

Checkout & Conversion

Custom UI on the information, shipping and payment steps is Plus-only; Thank You and Order Status extensions are open on every plan except Starter.

Checkout & Conversion
