Cart and checkout

Cart exits, checkout starts without payment and failed payments are different problems. We inspect the journey your plan actually supports — including Shopify Plus constraints on checkout UI extensions — before promising custom checkout UI.

01Starting points

Checkout starting points

When carts do not become paid orders

Use this page when the primary failure is after add-to-cart: unclear totals, checkout starts that stall, payment errors or recovery for identifiable shoppers.

01Shoppers leave the cart before checkout

Clarify totals, shipping and the path into checkout.

Unexpected costs, weak CTAs and mobile cart friction are reviewed before assuming checkout itself is broken.

Discuss this situation

02Checkout starts but payment never completes

Separate information, shipping and payment failures.

Address, rate, market eligibility and payment-provider errors need log-backed diagnosis — not another discount code as the first fix.

Discuss this situation

03You need checkout UI changes on Plus

Scope extensions only where the plan allows.

Checkout UI extensions on the information, shipping and payment steps require Shopify Plus. Basic checkout settings and styling are a different capability.

Discuss this situation

04Known shoppers abandon before purchase

Eligible recovery with suppression after purchase.

Recovery needs an identifiable recipient, consent and purchase suppression. We hand lifecycle design to Email & SMS when flows are part of the engagement.

Broader funnel diagnosis needed?

Product-page and journey-wide conversion research sits on Shopify CRO. Storefront redesign sits on Store Design & Development.

02Overview

  • Shopify Checkout
  • Shopify Plus (when required)
  • Payments
  • Shipping rates
  • Checkout UI extensions

We distinguish cart-to-checkout progression from payment-stage failure and from eligible abandoned-checkout recovery. Metrics use matched cohorts where reporting allows.

Shopify plan limits matter. Official Shopify documentation restricts checkout UI extensions on the information, shipping and payment steps to Shopify Plus. We confirm plan, extension targets and market settings before quoting checkout UI work.

Tax, legal policy wording and payment-provider decisions remain merchant-led. We help surface friction and supported configuration — we do not replace legal or tax advice.

No. Checkout UI extensions for the information, shipping and payment steps are available on Shopify Plus. Other plans rely on supported checkout settings, apps and theme-side cart improvements. We confirm eligibility before quoting.
