Tell us what your ideal checkout looks like
Shopify Checkout Extensibility puts full control in your hands. We build pixel-perfect checkout flows with custom UI extensions, post-purchase upsells, and branded thank-you pages that turn buyers into repeat customers.
From delivery customization to payment gating and loyalty rewards, every element of your checkout can be extended and personalized for your brand and customers.
Date pickers, delivery notes, custom shipping rules per product or collection.
Show, hide or rename payment methods based on cart value, location, or customer tags.
Custom branded order confirmation and tracking pages with upsells and social sharing.
Reward point redemption, tier-based discounts, and referral code application at checkout.
We follow a battle-tested checkout development process that gets your custom checkout live fast, with zero disruption to your existing store's revenue.
We audit your current checkout, identify friction points, and map out every extension needed — UI components, functions, and post-purchase flows.
All checkout extensions are built in a sandboxed environment, tested across devices, payment gateways, and edge cases before any live deployment.
We deploy to your live store, monitor conversion rates in real-time, and iterate based on data within the first 30 days post-launch.
Every checkout we build is engineered around conversion data. These are the real numbers our clients see after launching custom checkout extensibility projects with Jhango.
We were building Shopify Plus checkout extensions before most agencies knew they existed. Our depth of expertise means faster delivery, fewer bugs, and checkouts that genuinely perform.
Shopify's new Checkout Extensibility API gives unprecedented control. We use every capability to maximize your checkout conversion.
Custom colors, fonts, banners, and messaging throughout checkout. Your brand identity doesn't stop at the cart — it extends through payment.
After the customer completes payment, present one-click upsell offers. No re-entering payment info. Average acceptance rate: 12-18%.
Let customers choose their preferred delivery date. Perfect for perishables, gifts, and scheduled deliveries. Reduces "where's my order" tickets.
Gift messages, special instructions, VAT/tax IDs, loyalty numbers — custom fields that collect the data your business needs at checkout.
Custom validation rules — address verification, order minimums, age verification, product compatibility checks — all enforced at checkout.
Free shipping reminders, return policy, security badges, and estimated delivery times displayed at the right moments during checkout.
We analyze your current checkout flow, abandonment data, and conversion funnel to identify the highest-impact improvements.
We design checkout UI extensions that match your brand and are optimized for conversion. Mockups presented for your approval.
Checkout extensions built using Shopify's official APIs. Tested on staging, deployed to production with zero checkout downtime.
A/B testing and conversion tracking to measure impact. We iterate based on real data to continuously improve checkout performance.
Your checkout handles 100% of your revenue. Even small improvements create outsized results.
Branded checkout with trust signals and optimized layout consistently improves checkout conversion by 10-20%.
Post-purchase upsells generate $8-15 additional revenue per accepting customer — with zero impact on checkout completion.
Most checkout abandonment comes from trust issues, unexpected costs, and friction — all addressable with the right checkout customizations.
Jhango has deep expertise in Shopify's Checkout Extensibility APIs, having built over 100 custom checkout experiences on Shopify Plus. We understand the nuances of checkout UI extensions, payment customizations, and post-purchase flows that generic agencies simply cannot deliver.
