“Our cart abandonment was 78%. After Maple54 rebuilt our checkout, it dropped to 42%. One-click checkout + abandoned cart SMS recovers $40K/month in revenue that used to walk out the door.”
Checkouts engineered for higher AOV.
Default cart systems lose 30-50% of would-be revenue to abandoned carts, friction, and weak upsell logic. We rebuild carts that lift AOV + recover abandoners — typically 20-45% more revenue at identical traffic.
Cart audit + strategy
Week 1Funnel analysis (add-to-cart → checkout → purchase), abandonment-point identification, upsell-opportunity mapping, payment + shipping UX audit.
Build + integrate
Week 2-3Custom cart UI (slide-out + full-page variants), upsell + cross-sell logic, bundle builders, dynamic shipping + tax, multi-currency, PayPal + Apple Pay + Shop Pay.
Checkout optimization
Week 4Express checkout integrations, address autocomplete, phone-country detection, inline validation, friendly error states, trust signals placed strategically.
A/B testing + scale
Month 2+Test cart iconography, timing of upsells, bundle offers, checkout field order. Typical 15-30% CVR lift from 90 days of disciplined cart CRO.
The full checkout funnel, reimagined.
Cart UX, upsells, checkout, abandonment recovery, and payments — all coordinated as one system.
Custom cart UI + animations
Slide-out or full-page cart depending on UX research, subtle animations for add-to-cart feedback, instant quantity updates, clear cross-sell placements.
Upsell + bundle engine
One-click upsells, bundle builders, subscribe-and-save, tiered-discount logic, “free shipping over $X” progress bars. Built per-store, not templated.
Checkout + payments
Shopify Plus one-page checkout customizations, Shop Pay, Apple Pay, Google Pay, Klarna, Afterpay. Inline validation, address autocomplete, express checkout.
Abandonment recovery
Browse-abandon + cart-abandon + checkout-abandon flows in Klaviyo. SMS + email + push orchestration. Recovers 18-25% of would-be lost revenue on average.
Built for brands $500K+/year in ecommerce revenue.
Below $500K/year, default Shopify checkout works fine. Above that, small UX frictions cost $10K+/month. Custom cart pays for itself in one quarter.
High-AOV DTC
Furniture, jewelry, luxury goods. AOV-optimization features (bundling, warranty upsells, financing) have 5-10× the leverage than on low-AOV stores.
Subscription Commerce
Supplements, meal-kits, personal-care subscriptions. Subscribe-and-save UX is the #1 LTV driver; most themes botch the signup + management flows.
Gift + Bundle-Heavy
Gift boxes, curated bundles, personalization-based stores. Custom bundle builders + gift messaging flows unlock 30-50% AOV increases on these products.
B2B + Wholesale
Net-30 terms, quantity discounts, tax-exempt checkout, approval workflows. B2B ecommerce is fundamentally different UX from B2C.
Production-grade tooling, included.
Enterprise-grade engineering stack bundled in — no client pays separately for the tools we use every day.
Custom cart, answered honestly.
Will a custom cart slow down my site?
No — built correctly, custom carts are faster than default. Minified + tree-shaken JS, lazy-loaded off-canvas components, skeleton states. Typically 50-100ms faster than the Shopify default.
Shopify Plus vs. regular Shopify for checkout customization?
Regular Shopify allows cart customization but locks the checkout page. Shopify Plus unlocks full checkout.liquid customization. For high-volume brands, Plus pays for itself within 3-6 months via checkout CRO.
Do you integrate ReCharge / Bold / Recurly?
Yes. Native Shopify subscriptions + ReCharge + Bold Subscriptions + Recurly all supported. We wire custom cart UI into whichever subscription engine you're using (or migrate you if it's hurting CVR).
What's a good cart-abandonment rate?
Industry benchmark: 68-72% abandonment. Well-optimized stores reach 55-60%. Custom cart UX + recovery flows together typically drop abandonment 8-15 percentage points.
Will this break my theme?
No — we build alongside your existing theme, not replacing it. Typically deployed as a custom Shopify section + app-embedded blocks, so the core theme remains intact and upgrade-safe.
