Shopify Development & Integration

Shopify stores built and run by one team

As a Shopify store grows, the theme gets harder to change, apps pile up, and orders or stock counts drift between Shopify and your back office. We design and build custom Liquid themes, Shopify apps and headless storefronts on Next.js, and connect Shopify to your ERP, CRM, 3PL and accounting through its Admin and Storefront APIs. Webhooks are verified and processed once, syncs retry and reconcile, and the same team covers design, QA and monitoring after launch.

AI-assisted, expert-led Shopify development

How AI assists

Drafts Liquid sections, app code and GraphQL queries that engineers review, test and refine
Writes contract tests for webhooks and Admin API calls, including resent events and rate-limit responses
Proposes product, customer and order mappings for migrations and ERP syncs, for engineers to verify
Reviews webhook and sync logs to find failed jobs, duplicates and the orders they affect

What our experts own

Designers own storefront journeys, accessibility and the states shown when stock or payment fails
Engineers decide which system owns products, stock and orders: Shopify, your ERP or your 3PL
Engineers manage app credentials and API scopes, limiting each app to the access it needs
We approve launches, redirects and app permission changes, and own monitoring after go-live

How a Shopify order reaches your back office

Illustrative order-to-ERP path; your stack and agreed record ownership shape the real version.

Order placed
A completed checkout makes Shopify send an orders/create webhook to your app's endpoint.
Verify and record
The handler checks the HMAC signature, stores the webhook ID, and acknowledges before any heavy work starts.
Checkpoint: Unsigned or repeated events are dropped
Queued ERP push
A worker sends the order to your ERP or 3PL, retrying with backoff when either side rate-limits.
Fulfillment and stock
Tracking numbers and stock levels return through the Admin API, so Shopify reflects what the warehouse shipped.
Back-office reconciliation
Orders, stock and refunds in Shopify are compared with your ERP, and any gap is listed by order.
Checkpoint: Your ops team reviews each gap

When something fails: Failed pushes retry, then wait in a held-orders list with an alert; staff see the order tagged as not yet synced.

What you receive

What your Shopify project can include

Custom theme development
Liquid themes built from your brand and design system, checked for speed, accessibility and SEO before launch.
Custom and public apps
Shopify apps that extend the admin, checkout or storefront, with webhook handlers that verify each request and process every event once.
Headless commerce
Next.js storefronts on the Storefront API, with caching, content previews and a plan for SEO and inventory accuracy.
ERP, CRM and 3PL integrations
Orders, inventory, customers and fulfillment synced with your back office, with retries, rate-limit handling and scheduled reconciliation.
Subscription billing
Subscription apps or custom logic on Shopify's subscription APIs, with failed-renewal handling and clear customer messages.
Multi-store and markets
Inventory, pricing and content kept consistent across stores and markets, with alerts when a sync falls behind.

Prepare an integration that your team can operate

Access and inputs
Provide a development store or approved collaborator access, your plan, installed apps and the systems that own stock, orders and customer records. Bring examples of the data and failure cases to exchange.
A realistic first scope
Choose a defined theme, app or synchronization flow first. Checkout, subscriptions and B2B requirements must fit the actual plan and apps; migration and ongoing merchandising are agreed as separate work where needed.
Handover and maintenance
We deliver the agreed connection, test evidence, configuration notes and recovery instructions. Assign an owner for alerts and reconciliation. Provider changes, credentials and ongoing monitoring can be maintained under an agreed support plan; provider charges remain separate.

How we deliver your Shopify project

01
Discovery and store audit
Review your store, apps, integrations and data flows, agree goals, and decide which system owns products, stock and orders.
02
Design and prototypes
Designers prototype key journeys in Figma, mobile-first and accessible, including error and empty states, before build starts.
03
Build and test
Theme or app development with code review, contract tests on a development store, and performance and SEO checks.
04
Launch and improve
Staged launch with redirects, analytics and webhook monitoring in place, then fixes, API version upgrades and improvements on a support plan.

FAQ

Frequently Asked Questions

Can you migrate from WooCommerce to Shopify?

Yes. We migrate products, customers and order history, map old URLs to new ones with 301 redirects, and run test imports and checks before the switch. Cutover is planned for a low-traffic window with a rollback plan, to keep disruption for customers low.

Do you work with Shopify Plus?

Yes. We build checkout customizations with Shopify Functions and checkout UI extensions, wholesale and B2B setups, and automation for Plus stores. If your store still relies on older checkout customizations, we plan the move to Shopify's current extension tools.

What happens if a webhook or sync fails?

We design for it. Webhook handlers verify each request, record the event ID and process it once, so a resent event does not create a duplicate order or stock change. Failed jobs retry with backoff, and a scheduled reconciliation compares Shopify with your ERP and alerts your team to any gap.
