Why Custom Development

Your checkout loses more revenue than any other page — we fix that

The average Shopify store loses 70% of shoppers between add-to-cart and purchase. Most of that abandonment happens at checkout — confusing layouts, missing trust signals, no express payment options, and zero personalization. We customize every element of the Shopify checkout to reduce friction, build confidence, and increase order value. On Shopify Plus, we use Checkout Extensibility for deep customization. On standard Shopify, we optimize every lever available.

U

Checkout UI extensions that convert

Custom banners, trust badges, progress indicators, delivery date pickers, gift messaging, loyalty point redemption, and dynamic messaging — all built as native Checkout Extensibility extensions on Shopify Plus.

A

Upsells that increase AOV

In-checkout product recommendations, post-purchase one-click upsells, order bump offers, and free-shipping threshold nudges. Data-driven offers that feel helpful, not pushy — averaging a 15% lift in average order value.

T

Trust that eliminates hesitation

Security badges, money-back guarantees, estimated delivery dates, real-time shipping calculations, customer reviews at checkout, and payment security messaging. Every element designed to answer the question: "Is this safe?"

What's Included

Everything you need for a successful Shopify launch

01

Checkout Audit & Funnel Analysis

GA4 checkout funnel data, session recordings of checkout behavior, abandonment rate analysis, and competitive benchmarking. We identify exactly where and why shoppers drop off.

Checkout Branding & UI

Logo, brand colors, typography, and custom CSS applied to the checkout. On Plus, we build branded checkout UI extensions for banners, custom fields, and layout modifications.

02

Trust & Security Elements

SSL badges, payment security icons, money-back guarantee messaging, estimated delivery dates, and return policy highlights placed at high-anxiety points in the checkout flow.

Express Payment Optimization

Shop Pay, Apple Pay, Google Pay, and PayPal Express configured and positioned for maximum adoption. Express payment can reduce checkout time by 60% and significantly lift conversion.

03

In-Checkout Upsells & Cross-Sells

Product recommendations, order bumps, and free-shipping threshold nudges displayed during checkout. On Plus, these are native UI extensions. On standard Shopify, we use cart-level upsell strategies.

Post-Purchase Upsell Page

One-click post-purchase offer page shown after payment but before confirmation. Customers can add products without re-entering payment info. Typically converts 8–15% of buyers.

04

Custom Fields & Validation

Gift messaging, delivery instructions, company fields, PO numbers, and custom validation rules. Address auto-complete integration for faster form completion and fewer errors.

A/B Testing & Optimization

Controlled experiments on checkout elements — trust badge placement, upsell offer types, express payment positioning, and copy variations. Statistical analysis to deploy only proven winners.

Frequently Asked Questions

Common questions about custom development

Any Shopify plan can benefit from checkout optimization — trust badges, express payments, cart improvements, and abandoned cart recovery work on all plans. Full checkout UI extensions (custom branding, in-checkout upsells, custom fields) require Shopify Plus and Checkout Extensibility.

Checkout Extensibility is Shopify Plus's framework for customizing the checkout experience. It lets us build branded UI extensions, custom fields, payment and shipping customizations, validation rules, and post-purchase pages — all without modifying checkout.liquid (which Shopify is deprecating).

Our clients see an average 28% lift in checkout conversion rate. The biggest wins come from express payment adoption (reduces checkout time by 60%), trust elements (reduces abandonment anxiety), and post-purchase upsells (increases AOV by 15% on average). The exact improvement depends on your starting point.

After a customer completes payment but before the thank-you page, we show a one-click upsell offer. The customer can add a product to their order without re-entering payment info. It is zero-friction and typically converts 8–15% of buyers, generating significant incremental revenue.

No. Checkout Extensibility extensions run in a sandboxed environment and are designed for performance. We test every extension for load time impact before deployment. Express payments actually speed up the checkout significantly.

Yes. We run controlled experiments on checkout elements — trust badge placement, upsell offer types, copy variations, and express payment positioning. Tests run until statistical significance before we deploy winners. This data-driven approach ensures every change is validated.

Basic Checkout takes 1–2 weeks. Advanced Plus Checkout takes 3–5 weeks. A Full Checkout Overhaul with A/B testing takes 6–10 weeks (testing requires traffic volume for statistical significance). We provide a timeline during the proposal phase.
