Shopify Store Review

Free Core Web Vitals + theme code review - we'll tell you what's costing you conversions before you buy anything.

What we build on Shopify

Five capability groups covering themes, custom apps, checkout extensibility, integrations, and the ops work that keeps a store fast after launch.

Shopify's the right platform for the vast majority of merchants - until you start hitting the template's ceiling on merchandising, checkout, or integration. That's when we come in. We ship Online Store 2.0 themes, checkout UI extensions, Shopify Functions, custom apps, and headless Hydrogen builds.

Theme development & storefronts

Custom themes, not template forks. Sections that merchandisers actually use, performance that passes PageSpeed, and code a future agency can pick up without a rewrite.

  • Custom Online Store 2.0 themes - JSON templates, sections everywhere, app-block compatible
  • Dawn-based theme customization - section and block architecture, responsive design, accessibility (WCAG 2.2 AA)
  • Metaobjects and metafields - content modeling for lookbooks, bundles, FAQs, size guides, brand pages
  • Custom sections - sliders, mega-menus, product comparison, PDP galleries, configurators, bundle builders
  • Theme performance - lazy loading, critical CSS, deferred JS, image CDN tuning, Lighthouse budget enforcement
  • Localization - multi-currency, multi-language, Markets setup, Shopify Translate & Adapt, hreflang hygiene
  • B2B storefronts on Plus - company profiles, price lists, catalogs, payment terms, volume pricing
  • Hydrogen + Oxygen headless builds in React Router / Remix when theme customization hits its limits

Custom apps & admin extensions

Public apps for the App Store or custom apps for one merchant's private needs. Shopify CLI, Polaris, App Bridge, and the App Bridge Session Token auth pattern.

  • Custom apps for single-merchant use - Remix + Shopify CLI template, Prisma, Polaris UI, hosted anywhere
  • Public App Store apps - billing API, app listing, privacy webhooks, GDPR data-request handlers, app review prep
  • Admin UI extensions - product admin actions, order admin blocks, customer segment actions, inline Polaris React
  • Theme app extensions - app blocks merchants drop into sections without editing Liquid, metafield-driven config
  • Webhooks for orders/create, products/update, customers/redact - retries, HMAC verification, idempotency keys
  • Bulk operations (GraphQL bulkOperationRunQuery) for 100k+ product imports / exports without rate-limit pain
  • Multipass for SSO from an external platform into the storefront with session handoff
  • GraphQL Admin API clients with rate-limit-aware retry, cost-based throttling, persisted queries

Checkout extensibility & Shopify Functions

The checkout that used to require Plus Scripts. Now it's extensions and Functions - properly versioned, typed, and testable.

  • Checkout UI extensions - inline banners, cross-sells, address validation, custom fields on information step
  • Shopify Functions in Rust or TypeScript - discount, payment, delivery, cart transform, cart validation, fulfillment constraints
  • Cart transform function - bundle child products as single parent, custom SKU composition at checkout
  • Custom discount logic - BOGO, tiered, loyalty-point, gift-with-purchase, member-exclusive
  • Payment customization - hide/sort/rename payment methods by cart contents, customer tags, or region
  • Delivery customization - hide/rename/reorder shipping methods, free shipping rules, carrier-calculated overrides
  • Post-purchase extensions - upsells, surveys, warranty offers, subscription opt-ins
  • Shopify Flow triggers, conditions, actions - merchant-facing automation between apps without code

Integrations - ERP, 3PL, POS, marketing

Where Shopify stops being the whole stack. Inventory, financials, shipping, and lifecycle marketing - all reconciled.

  • NetSuite, SAP Business One, Dynamics 365 BC, Acumatica integrations - SKU/inventory/order/refund sync
  • 3PL integrations - ShipBob, ShipStation, ShipHero, Cin7, Deposco - fulfillment service apps with status webhooks
  • Shopify POS Pro - POS UI extensions, custom discounts at register, inventory lookup across locations
  • Loop Returns, Returnly, AfterShip Returns - RMA workflow + restock logic + refund reconciliation
  • Klaviyo, Attentive, Postscript - customer/segment/order sync, flow triggers, tag-based list management
  • Gorgias, Zendesk - customer context sync, order lookup widgets, return/refund actions from ticket view
  • Analytics - Shopify Pixel API (custom pixels), GA4, Meta CAPI server-side, TikTok Events API
  • Subscription apps - Recharge, Bold, Skio - subscription flow, pause/skip/swap, churn reduction flows

Performance, ops & long-term maintenance

The work that keeps a launched store actually performing months after go-live.

  • Core Web Vitals monitoring - LCP, INP, CLS tracked per template, budgets enforced in CI
  • Image optimization - responsive srcset, WebP/AVIF, Shopify CDN params, preload hints for hero images
  • Theme Inspector profiling, Liquid render time reduction, JavaScript deferral audits
  • A/B testing setup - Intelligems, Shoplift, or custom section-level tests with data warehouse analysis
  • SEO hygiene - structured data (Product, Breadcrumb, FAQ, Review), canonical tags, sitemap audits
  • CI/CD - Shopify CLI theme deploys, GitHub Actions, theme diff review on PR, staging themes per branch
  • Theme monitoring - Theme Store compliance checks, deprecated Liquid tag sweep each release
  • Plus store maintenance retainer - weekly release review, broken-app monitoring, staged upgrades
faq

Common questions from Shopify merchants

Default to Shopify themes (Online Store 2.0). Go headless (Hydrogen + Oxygen, or Next.js + Storefront API) when you need a content-heavy experience, very custom PDP logic, or to unify multiple storefronts. We'll help you decide; the answer is 'stay on themes' more often than most agencies admit.

Yes - Checkout Extensibility with UI extensions and Shopify Functions covers almost everything Scripts did, plus things Scripts couldn't (cart transform, delivery customization, post-purchase). We ship Functions in Rust or TypeScript depending on perf requirements.

Yes - both custom apps (for a single merchant) and public App Store apps, including billing API, App Store review preparation, and the GDPR data-request / customer-redact / shop-redact webhook trio.

Yes - NetSuite, SAP B1, Dynamics 365 BC, ShipBob, ShipStation, ShipHero are recurring work. We handle both sides (Shopify webhooks + app, and the ERP side via its API or middleware) so you don't end up with two vendors blaming each other.

Yes. Our engineers hold Shopify certifications and we build in Partner dev stores before shipping to Plus production.

A 2-week paid trial scoped to a single deliverable - typically a theme section, a checkout extension, or an integration. If it works, we convert to monthly at $1,800-$2,400/engineer/month.
