ZTABS provides E-commerce development — Custom e-commerce development for B2C and B2B — Shopify, Shopify Plus, headless commerce with Next.js, and fully custom storefronts. Payment integration, inventory sync, and conversion-optimized checkout flows. 50+ stores built across retail, fashion, food, and wholesale. Our capabilities include custom E-commerce, secure payments, order management, and more.
50+ stores live across Shopify, Shopify Plus, headless Next.js, and WooCommerce — checkout-conversion lifts of 18–35% on the rebuilds, with full Stripe/PayPal, multi-currency, and ERP/3PL sync wired in.
E-commerce development is a spectrum: on one end, you have Shopify stores that can be launched in weeks; on the other, fully custom headless commerce architectures that take months but give you complete control over every pixel and integration. We build across the entire range and help you choose based on your catalog size, customization needs, and budget. For most direct-to-consumer brands doing under $5M annually, Shopify Plus is the right choice — we customize themes, build custom apps for unique functionality, and integrate with your ERP, warehouse, and marketing tools.
For brands that need complete control — custom checkout flows, complex B2B pricing, multi-currency multi-warehouse setups — we build headless commerce using Shopify's Storefront API or Medusa as the commerce engine with a Next.js frontend. This gives you sub-second page loads, full design freedom, and the ability to sell through any channel (web, mobile, in-store, wholesale portals). We also add AI to e-commerce: personalized product recommendations based on browsing behavior, AI-powered search that understands natural language queries, automated inventory forecasting, and dynamic pricing optimization.
Every store we build is optimized for conversion — fast loading, mobile-first, with clear CTAs, trust signals, and streamlined checkout flows that minimize cart abandonment.

Across our portfolio, we track delivery patterns to improve outcomes. Our internal data from 2023-2026 shows:
| Alternative | Best For | Cost Signal | Biggest Gotcha |
|---|---|---|---|
| DIY Shopify theme / Squarespace / Wix Stores | Small catalogs (<200 SKUs), single-region sales, and founder-operated stores with <$500K/year GMV. | $29–$200/month platform + $0–$350 theme (indicative). | Themes bottleneck at 300–500 products (collection pages slow, search breaks), and checkout customization is locked behind Shopify Plus ($2K+/month). Abandoning a theme mid-growth costs 3–6 weeks of rebuild. |
| Freelancer on WooCommerce or basic Shopify | A single-store launch with <50 products and an owner who can manage content day-to-day post-launch. | $30–$80/hour; typical store $4K–$15K (indicative). | Most solo freelancers skip performance work (image optimization, page speed, structured data) and accessibility. Your PageSpeed Insights score will cap around 40–55, which costs you 15–30% of organic traffic vs. a tuned store. |
| Boutique e-commerce agency (ZTABS tier) | DTC brands doing $1M–$50M GMV needing conversion-optimized storefronts, headless architecture, or complex B2B catalog logic. | $90–$180/hour; $25K–$200K per engagement (indicative). | Headless Shopify (Hydrogen/Next.js) adds 30–50% build cost for 10–15% performance gain — we'll push back if you're <$3M GMV. Most brands are better served by a well-optimized Online Store 2.0 theme at that scale. |
| Enterprise commerce platform (Salesforce Commerce Cloud, Magento Commerce, commercetools) | Global merchants with 50+ stores, multi-currency, B2B workflows, and $50M+ GMV where platform fees are rounding error. | $80K–$800K/year platform + $500K–$5M implementation (indicative). | Implementation partners run 18–24 month projects and their typical 'go-live' slips 2–4 times. You're buying a platform contract that outlasts your current exec team — plan for re-platform RFP in year 4. |
| In-house e-commerce team | Brands at $50M+ GMV with a dedicated VP of E-commerce, weekly release trains, and 24/7 store ops needs. | $900K–$2M/year loaded for a 5-person team (indicative). | Mid-market brands under-invest here: they hire one 'Shopify admin' and expect full-stack output. The correct minimum is designer + dev + merch ops + analytics — below that, outsource to agency. |
Shopify vs. custom headless. Online Store 2.0 Shopify theme: $300 theme + $39–$399/month + 10–30 hours config = $2K–$8K build. Headless Shopify (Hydrogen on Next.js): $40K–$90K build + $2K–$6K/month ops. Headless wins only when: (1) you're >$3M GMV where 10% conversion uplift = >$300K/year, (2) you need non-standard checkout flows (B2B quotes, configurators), or (3) SEO programmatic pages drive >20% of traffic. Below $3M GMV, themed Shopify beats headless on ROI for 3+ years. WooCommerce vs. Shopify TCO. WooCommerce: $0 license + $30–$300/month hosting + $200–$1K/year plugin stack + ongoing security patching. Shopify: $39–$399/month + 2.4–2.9% + $0.30/txn payment fees. Crossover at ~$200K/year GMV — below that, Shopify wins because payment-fee delta is small and admin time saved is real (10–20 hours/month). Above $2M GMV with custom plugin needs, WooCommerce TCO beats Shopify. Agency vs. in-house e-commerce. A mid-market brand ($5M–$20M GMV) typically needs 0.8–1.5 FTE of e-commerce engineering. A senior Shopify dev loaded costs ~$180K/year; an agency retainer at equivalent capacity runs $8K–$14K/month ($96K–$168K/year). Agency wins below 1.5 FTE need. Above 2 FTE sustained plus merchandising ops, hire a VP of E-commerce and build in-house.
A client accepted the dashboard's 'Update theme' button. The update overwrote 14 custom Liquid files containing their product badge logic, free-shipping bar, and upsell widgets. Reverting took 2 weeks because the dev had no Git backup. Fix: always fork themes via GitHub integration (Shopify CLI), never edit in the online editor for production, and lock theme updates behind a PR review.
A DTC brand added Klaviyo, Yotpo, ReCharge, PushOwl, Tidio, and Privy — each injected 2–8 third-party scripts. LCP went from 1.8s to 4.6s on mobile; organic traffic fell 22% over 90 days. Fix: audit scripts with PageSpeed + WebPageTest, defer non-critical scripts to requestIdleCallback, lazy-load below-the-fold apps, and remove apps with <20% attributable revenue. Recovery took 8 weeks.
A client with nexus in 14 US states used Shopify's default tax engine, which aggregates state rates but misses ~3,000 local jurisdictions (e.g., Louisiana parish taxes, Colorado home-rule cities). Quarterly sales-tax filing triggered a $47K under-collection liability. Fix: switch to TaxJar or Avalara for states with home-rule complexity; Shopify's basic engine is fine for <5 states without local tax layers.
A brand synced inventory from NetSuite to Shopify via a 15-minute batch job. A flash-sale email drove 800 orders in 6 minutes; 340 oversold before the next sync. Fix: move to event-driven sync (NetSuite → webhooks → Shopify Inventory API per SKU change), buffer critical SKUs with 5–10 unit safety stock, and pause flash-sale SKUs when buffer depletes.
A DTC brand shipped internationally via DHL but never filled product HS tariff codes. 40% of EU and UK parcels got held at customs, 8% returned undelivered, reviews tanked. Fix: populate HS codes on all SKUs (Shopify product metafields + DHL/Shippo integration), default country-of-origin values, and test a handful of orders per country before opening sales there.
