ECOMMERCE DEVELOPMENT
Custom ecommerce development for Shopify Plus brands at scale.
Theme builds, platform migrations, B2B catalog architecture, headless patterns, and custom app development, the work most agencies sub out to offshore teams. We build it in-house. 400+ stores shipped across DTC, B2B, retail, and service commerce.
What We Actually Build?
Ecommerce Development is the umbrella for seven dedicated service lines. Each is its own deep specialization with its own subpage. The work below is what every engagement starts from.
- Custom Shopify Plus theme development. built from scratch, not reskinned
- Figma to Shopify Liquid execution, pixel-perfect, block-based, editor-friendly
- Platform migrations from Magento, WooCommerce, BigCommerce, Wix, Squarespace
- UX/UI design for ecommerce, wireframe, prototype, hand-off
- International expansion, Shopify Markets, multi-currency, multi-language
- B2B commerce, wholesale channels, catalog logic, custom pricing
- Custom app development, Shopify Apps, headless integrations, API work
Who this is for?
Shopify Plus brands doing $200K to $2B in annual revenue, B2B-leaning DTC brands, service-based commerce on Shopify (med spa, salons, booking-first), and brands ready to leave Dawn reskins or page-builder themes behind. We don’t take on first-time Shopify stores under $50K, that’s not where our value is.
Process
Behavioral segmentation
RFM (Recency × Frequency × Monetary) segmentation isn’t optional. Every brand we audit either has zero segmentation or has the platform’s default segments and never customized them. We build RFM grids tuned to your purchase cycle, then tier customers into Champions, Loyal, At-Risk, Hibernating, and Lost. Every campaign and flow segment downstream uses these tiers.
Channel layering, email + SMS + push
Channels work harder when they work together. We coordinate email for storytelling, SMS for urgency, and push for time-sensitive nudges. The Omnisend 2026 report showed SMS click rates more than doubled year-over-year and push automation conversion rates reached 22.9%. Single-channel retention is leaving 30%+ of attainable revenue on the table.
Subscription optimization
For brands with subscription SKUs, churn is the silent killer. We rebuild subscription pages, optimize cancel flows, add pause-instead-of-cancel logic, and run win-back sequences for cancelled subscribers. Typical lift: 15–25% subscription retention improvement in 90 days.
Replenishment and predictive timing
Klaviyo’s predictive next-purchase date. Tag-based replenishment triggers in Brevo. Behavior-triggered SMS in Attentive. Each platform handles it differently. We build for whichever you’re on
Lifecycle-stage personalization
First-time buyers, repeat customers, and VIPs don’t receive the same email. Sounds obvious. Almost no brand actually does it. We tag every subscriber by lifecycle stage at the data layer and use those tags as the primary segmentation axis for both flows and campaigns.
Loyalty and referral architecture
Points-based rewards. Tiered VIP programs. Referral incentives that pay both sides. We build loyalty in Klaviyo (native or via Smile/Stamped integration), LoyaltyLion, or your platform of choice. Best-in-class brands see 5x ROI from loyalty programs.
Post-purchase upsell and cross-sell
ReConvert, AfterSell, or native Shopify Plus post-purchase upsells in the thank-you page, plus email-driven cross-sell sequences. Average order value typically lifts 8–18% from this layer alone.
Continuous testing and iteration
Subject lines, send times, segment composition, offer structure, channel mix. We run A/B tests on every campaign and quarterly reviews on every flow. Retention without testing is a one-time setup. Retention with testing is a compounding asset.

FAQs
Do you use page builders like Elementor or PageFly?
No. Every theme we build is custom Liquid + Theme Editor sections. Page builders add page weight, slow Core Web Vitals, and lock your team into the builder’s pricing. We build sections in the native Shopify Theme Editor so your team can edit anything without code.
What's your turnaround for a custom Shopify Plus theme?
Typical scope: 6–10 weeks from kick-off to launch. We give a fixed timeline in the SOW after the discovery call. If we say 8 weeks, we ship in 8 weeks.
Do you work with existing Figma files or do you design too?
Both. If you have a Figma file, we execute it 1:1 to Liquid. If you don’t, we design in Figma first, get sign-off, then build.
