Verticals served
What we engineer
Themes, apps, integrations, Plus.
Theme work done right is software engineering, not Liquid gluing. The difference shows up six months after launch.
OS 2.0 themes
Sections everywhere, metafield-driven content, documented handoff — the merchandising team keeps shipping.
Custom apps
Node/Remix, Admin GraphQL, webhooks, App Bridge — for pricing, wholesale, subscription logic, integrations.
Integrations
ERP (NetSuite, SAP, Oracle), 3PL, CRM, email, reviews, subscriptions — with idempotency + reconciliation.
Shopify Plus builds
Functions, Flow, B2B, multi-store, HQ — built Plus-first, not upgraded to Plus later.
Shopify Functions
Cart transforms, payment customization, checkout validation, pricing logic — at the edge, in milliseconds.
Shopify Flow
Order routing, fraud screening, inventory, fulfillment branching — reviewable, documented automation.
Hydrogen / headless
Honest decision tree. Hydrogen when it's right (editorial + CMS needs, React team, scale DX). Not by default.
Performance engineering
LCP < 2s, INP < 200ms, CLS < 0.1. Budgets enforced at every PR via Lighthouse CI.
Stack we ship on
Shopify-native tooling, official SDKs only.
A Shopify Web Development Agency that ships engineering, not theme-slinging. OS 2.0 themes, custom apps, ERP integrations, Shopify Plus builds, Hydrogen when it's right. Dedicated squad per engagement; no rotating pool.
Five dev disciplines
How Shopify development ships here.
Five silo sub-services — from engineering philosophy to full service list.
Shopify Development Agency
A Shopify Development Agency that only does theme work is half an agency. Real Shopify development covers four workstreams that compound: theme architecture, custom apps, integrations, and performance engineering — each shipped by engineers who know the platform's sharp edges.
What separates engineering from theme-slinging on Shopify: Liquid written like documentation (not clever tricks), metafield-driven content with typed admin views, sections-everywhere architecture that the merchandising team can extend, integrations with idempotency and reconciliation instead of fire-and-forget webhooks, custom apps with observability from day one. The difference shows up six months after launch when the theme still works and the integrations still reconcile.
Our development philosophy: boring wins. No clever Liquid tricks. No undocumented snippets. No webhooks without retry logic. Structured logs, Sentry for errors, daily reconciliation jobs, feature flags for risky rollouts, and every change ships with a Lighthouse report on the PR.
Shopify App Development Agency
As a Shopify App Development Agency, we build the apps that don't exist in the App Store — because the logic is merchant-specific, the integration goes deeper than public apps can reach, or the off-the-shelf option is built for a different use case and it shows.
Typical custom app work:
- Pricing + discount logic that doesn't fit native discounts or Functions alone — tiered pricing, customer-specific rules, time-window campaigns, wholesale pricing matrices
- B2B extensions — quick-order forms, CSV upload, per-retailer catalogs, approval workflow UI that extends native Plus B2B
- Subscription logic on top of ReCharge/Bold/Stay AI — custom skip/swap UX, retention-triggered offers, bundle subscriptions, gift subscriptions
- Integration middleware — bi-directional ERP/3PL/CRM sync when Shopify-native apps don't exist or don't handle edge cases (tax, currency, multi-warehouse)
- Internal tooling — admin-only apps for merchandising, reporting, operations, custom dashboards
Stack defaults: Remix + TypeScript (Shopify's official stack for new apps), Node + Express for legacy maintenance. GraphQL Admin for all writes; REST only where GraphQL doesn't support. Postgres via Prisma when custom data model needed, or Shopify metafields/metaobjects when data belongs with the store.
Public apps we build through App Store submission — screenshots, GDPR + privacy posture, billing integration, review cycles. Private apps ship faster without the submission overhead.
Shopify Website Agency
A Shopify Website Agency covers the full website layer — not just themes, not just apps. Website-level engineering means every template renders fast, every integration is production-grade, every admin-facing surface is documented, and the whole thing is testable in staging before it touches production.
What our website engagements actually include:
- Theme layer — OS 2.0 sections, blocks, metafields, app blocks, theme settings designed for merchandising UX,
settings_schema.jsonas product - App layer — custom apps for merchant logic, middleware apps for integration, admin tools for internal teams
- Integration layer — ERP, 3PL, CRM, email, reviews, subscriptions, helpdesk — each with observability and reconciliation
- Performance layer — LCP <2s, INP <200ms, CLS <0.1 on mobile as build constraints, enforced at PR
- Accessibility layer — WCAG 2.1 AA semantics verified pre-launch and 30 days post-launch
- Admin layer — handoff documentation so the merchant team operates without calling us
- Observability layer — Sentry, structured logs, integration health dashboards
Website engagements ship as fixed-scope projects (10–20 weeks typical) or monthly retainers after launch ($8k–$20k/mo, or $20k+/mo on Plus dedicated-squad).
Shopify Web Development Company
A Shopify Web Development Company is measured on the governance it brings — not just the code it writes. Plus shops often have multiple agencies, freelancers, and in-house devs shipping to the same theme. Without governance, you get unreviewed code, broken deploys, conflicting changes, and a theme nobody fully understands.
Governance we implement on every engagement:
- PR templates + review requirements — no direct pushes to production branch, minimum one reviewer, Lighthouse report attached
- Release branches + cadenced deploys — weekly or per-sprint release cadence, not continuous chaos
- Feature flags for risky rollouts, with explicit ramp % in Liquid or app-managed toggles
- Rollback capability on every deploy, tested quarterly
- Audit trails via Plus admin logs wired to external logging (Datadog, Honeycomb)
- Theme lock-down — production theme protected from direct admin editing; changes require PR
- Staging parity with production — same app stack, test data not live
The team shape matches the governance. Minimum two engineers, one design lead, one project lead — named and dedicated to your account. No rotating pool, no offshore reseller, no "resource assigned next quarter."
