integration & API.
Custom Shopify integrations and headless storefronts when the theme economy isn't enough.
S What is Shopify?
Shopify in plain English.
Shopify is the world's leading ecommerce platform, hosting millions of online stores from small independents to global brands. It handles checkout, payments, inventory, shipping, and the storefront in one platform.
What businesses use it for
Common Shopify
use cases.
- 01 Online stores selling physical and digital products
- 02 Multi-channel selling across web, social, and marketplaces
- 03 Subscription and recurring billing through Shopify Subscriptions
- 04 Multi-store and multi-currency international ecommerce
- 05 B2B wholesale through Shopify Plus
Why custom?
Beyond the default Shopify integrations.
Shopify is the ecommerce default for good reason — but the default theme/app combination has limits. We build custom Shopify integrations: headless storefronts on Shopify Storefront API, custom apps for unique workflows, ERP and accounting sync, and bespoke checkout extensions when your business model is unusual.

How a Shopify project usually unfolds
How a Shopify project usually unfolds.
- 01
Audit the store and the surrounding stack
A working session with the ecommerce lead and operations to understand the catalogue shape, fulfilment workflow, accounting and marketing stack, and where the current theme or app combination is creaking. Out of that we agree what to extend on theme and what needs custom app or headless work.
- 02
Design the integration and storefront approach
API access provisioned (Admin, Storefront, or both), product and customer data model decided, and the call made on theme customisation, custom app, or headless build. Payment, tax and shipping decisions get made here too.
- 03
Build in phases
Highest-pain piece first — usually the accounting or ERP sync, or the storefront work the customer can see — then the deeper integrations and reporting. Each phase ships behind the right flags so the store stays trading the whole time.
- 04
Handover with documentation and a maintenance arrangement
Operations and marketing team training, a runbook covering the integration points and what to check when an order looks wrong, and an agreed support arrangement for the months after launch.
Typical investment $15K–$80K depending on scope
Typical timeline 5–14 weeks to first delivery
What you can expect
What a Shopify integration usually delivers.
A storefront that matches the brand and performs
Whether through a custom theme or a headless build, the customer experience matches the rest of the brand and the technical performance does not get in the way of conversion.
Accounting and operations that stay in sync
Orders, refunds, payouts and customer data flow into Xero, MYOB, the ERP or warehouse system with proper handling for GST, multi-currency and edge cases the default apps gloss over.
Marketing wired to real ecommerce events
Klaviyo, Mailchimp and lifecycle pipelines fire on the events that actually matter — abandoned cart, post-purchase, browse abandonment — using the data model the team has agreed on, not a templated install.
A platform that handles the next stage of growth
The build is shaped so that scaling channels, opening new markets, or moving to Shopify Plus does not require a rebuild. The custom layer survives the platform tier change.

How we build
Production-grade.
Not Zapier in a trench coat.
Every Shopify integration we ship handles failure properly: idempotent jobs, retry logic, dead-letter queues for unrecoverable cases, and observability so you can see exactly where data is at any moment.
Tested
Real test suite, real edge cases. Not just "it worked once."
Observable
You see what is happening — events logged, errors surfaced.
Maintainable
Documented, version-controlled, handed over properly.

FAQ
Common questions about Shopify integration.
Do you build custom Shopify themes or apps?
Both — custom themes (or Liquid customisation of existing themes) and private/custom Shopify apps for unique business logic that does not fit the public app store.
Can Shopify integrate with Xero, QuickBooks, or MYOB?
Yes — we build Shopify ↔ accounting integrations that handle GST, multi-currency, refunds, and proper reconciliation. Beyond what the default app store integrations cover.
Should we go headless on Shopify?
Headless is right when performance, design freedom, or unusual catalog requirements outweigh the simplicity of a Shopify theme. We help you make that call honestly — most stores are better off on a quality theme.
