ZTABS provides shopify development — From custom Shopify themes and apps to Shopify Plus enterprise solutions, we build e-commerce experiences that drive sales. Whether you're launching your first store or scaling to millions in revenue, we make Shopify work harder for your business. Our capabilities include custom shopify themes, shopify app development, shopify plus, and more.
60+ Shopify and Shopify Plus stores live — average checkout-conversion lifts of 15–30% on rebuilds, custom theme development in native Liquid (not page builders), and full ERP/3PL/POS sync wired in.
Shopify is the strongest e-commerce platform for most brands, but the default experience — a stock theme with basic apps — leaves conversion on the table. We build custom Shopify stores that are designed to convert, not just to look good. That means custom themes built with Shopify's Online Store 2.0 architecture (section-based, easy for your team to edit), optimized checkout flows that reduce cart abandonment, and strategic upsell and cross-sell mechanics that increase average order value.
For Shopify Plus merchants, we build custom checkout extensions, B2B wholesale channels, multi-location inventory management, and advanced automation with Shopify Flow. We also develop custom Shopify apps when the app store doesn't have what you need — subscription management, product configurators, loyalty programs, and integrations with ERP, 3PL, or custom warehouse systems. For brands that want maximum design freedom and performance, we build headless Shopify stores using the Storefront API with a Next.js frontend.
This approach delivers sub-second page loads, complete design control, and the ability to create content-rich shopping experiences that outperform template-based stores. Migration is a specialty: we handle Magento-to-Shopify, WooCommerce-to-Shopify, and BigCommerce-to-Shopify migrations with full product, customer, and order data preservation plus 301 redirect mapping for SEO continuity.
Each migration type has unique requirements. Explore our dedicated service pages for detailed process, pricing, and FAQ information.

Across our portfolio, we track delivery patterns to improve outcomes. Our internal data from 2023-2026 shows:
| Alternative | Best For | Cost Signal | Biggest Gotcha |
|---|---|---|---|
| Free/paid Shopify theme + in-house setup | Solo merchants launching <100 SKUs with standard apparel/beauty/consumer-goods flows and no custom app integrations. | $0–$350 theme + $39–$299/month + 20–60 hours DIY (indicative). | Every 'custom tweak' accumulates technical debt in the theme — after ~15 Liquid edits, updates become impossible and you're stuck on the theme version you started with. Migrations cost 2–4 weeks later. |
| Shopify Expert marketplace freelancer | Theme-switch projects, single-section builds (quiz, bundle builder), and app installations with minor Liquid changes. | $40–$120/hour; typical small project $2K–$10K (indicative). | Most Shopify Experts don't write React/Node apps or work with Shopify Functions (the new replacement for scripts). Anything beyond theme work — checkout extensibility, custom apps, B2B flows — needs a different specialist. |
| Boutique Shopify agency (ZTABS tier) | DTC brands at $1M–$50M GMV, Shopify Plus merchants, and brands needing conversion-optimized OS 2.0 themes + custom apps. | $90–$180/hour; $20K–$150K per engagement (indicative). | We'll push back on apps — most stores install 12–18 apps, half unused. Before we build, we audit the app stack and typically remove 5–8. Not all clients like being told their $400/month of apps are dead weight. |
| Shopify Plus Partner / elite agency (Eastside Co, Swanky, Fostr) | Plus merchants at $10M–$100M+ GMV needing checkout customization, B2B workflows, and replatforming from Magento/SFCC. | $150–$280/hour; $100K–$1M+ engagements (indicative). | Expect 4–8 weeks of discovery + technical architecture before build. Elite partners run Plus programs with migration specialists, ops teams, and conversion research — you pay for depth, not just dev hours. |
| Headless Shopify (Hydrogen / Next.js + Storefront API) | Content-heavy commerce (editorial + shop), brands with >$5M GMV where programmatic SEO pages drive material revenue, and non-standard checkout flows. | $40K–$150K build + $1K–$4K/month infra (indicative). | You lose ~30% of Shopify theme apps (they hook into Liquid, not the Storefront API). App auditing becomes a pre-requisite, and any app you rely on must have a Storefront API integration. |
OS 2.0 theme vs. headless Hydrogen. Custom OS 2.0 theme: $8K–$30K build + $39–$2.3K/month platform. Headless Hydrogen/Next.js: $40K–$150K build + $39–$2.3K/month Shopify + $1K–$4K/month Vercel/hosting. Headless only wins when: (1) GMV >$3M and 10% CVR uplift = $300K+/year, (2) editorial content drives >20% of traffic, (3) you need non-standard storefronts (multi-region pricing, configurators). Below $3M GMV, headless ROI is 4+ years — stay on themes. Shopify Basic vs. Shopify Plus. Basic: $39/month + 2.9% + $0.30 processing + $6.5K feature ceiling (launch, themes, basic automation). Plus: $2.3K/month + 2.5–2.7% processing + access to Checkout Extensibility, Shopify Functions, B2B, Scripts (legacy), and wholesale channel. Plus pays back at ~$2M GMV when processing-rate savings (~0.3%) = $6K/year and unlocks features that drive 5–10% CVR uplift. Below $800K GMV, stay on Basic/Advanced. App stack TCO. Typical $5M GMV brand runs 12–18 apps at $20–$500/month each = $600–$3K/month = $7K–$36K/year. Replacing 4–6 of those apps with custom Liquid sections in the theme costs $8K–$20K one-time, payback in 12–18 months, and improves CWV by removing 4–6 third-party scripts. Audit apps every 6 months; most teams find 30–40% of monthly app spend is redundant or unused.
A client had 8 months of custom Liquid work on product pages — all done via Shopify's online code editor, not Git. A 'Theme Update' prompt from their dev (meaning well) overwrote the customizations. 2 weeks of rebuild from Wayback Machine + memory. Fix: always use Shopify CLI + GitHub integration for production themes, enforce PR review for theme changes, and disable the online editor for non-dev admin roles.
A beauty brand installed Shopify Inbox, Klaviyo, Yotpo, Tidio, and PushOwl — each injecting 3–8 scripts. Mobile LCP went from 1.9s → 5.2s over 4 months; organic dropped 28%. Fix: defer non-critical scripts via <script defer>, lazy-load chat/reviews below-the-fold, and remove apps without attributable revenue. Recovery: LCP back to 2.1s in 6 weeks.
A dev 'cleaned up' the product form and removed data-shopify-xr-hidden / dynamic checkout variant attributes. Shop Pay button stopped rendering; CVR dropped 14% for 3 days before anyone noticed. Fix: preserve Shopify's dynamic checkout variables ({{ form | payment_button }}), test Shop Pay on staging with real Plus account, and add a Lighthouse CI check that fails if Shop Pay button is missing on PDP.
A 3PL integration consumed orders/fulfilled webhooks but returned 500s during a 40-minute DB migration. Shopify retried 19 times over 48 hours then gave up. 1,200 orders never synced to the 3PL. Fix: subscribe webhooks to SQS or a durable queue (never direct handler), add dead-letter queue monitoring, and use Shopify's webhook admin to replay missed events after any 3PL outage.
A Plus merchant had $45K of Checkout.liquid custom code (custom fields, upsells, trust badges). Shopify announced Checkout.liquid sunset (Aug 2024 → extended multiple times); migration to Checkout Extensibility required rewriting everything as UI Extensions. Project took 10 weeks. Fix: inventory Checkout.liquid customizations NOW, plan a 2-3 sprint migration, and use Checkout UI Extensions + Shopify Functions as the new primitives.
