Custom Shopify apps, integrations and commerce automation
When off-the-shelf apps hit their limits, we build the private apps, APIs, Shopify Functions and integrations that connect your store to the systems that actually run your business.
Business problems we remove
Most of these aren't Shopify problems. They're gaps between Shopify and everything else you run.
Manual order entry
Staff re-typing orders from Shopify into another system, one line at a time.
Inventory mismatches
Stock levels that disagree between your store, warehouse and ERP.
Duplicate customer records
The same customer created twice across Shopify and your CRM.
Disconnected pricing
Wholesale, promotional or contract prices maintained in two places.
Slow fulfilment
Orders waiting on manual steps before they reach the warehouse.
App limitations
An app that almost does the job, but not the part that matters.
Repetitive admin
Daily exports, imports and copy-paste that never end.
Unsupported checkout requirements
Checkout rules or fields the platform won't give you out of the box.
Poor error visibility
Failed syncs you only find out about when a customer complains.
What we build
Seven ways we extend Shopify beyond what the app store covers.
Private apps
Shopify's admin and the app store don't cover your workflow
Shopify app developmentPublic apps
You want to distribute an app to other merchants
Shopify app developmentShopify Functions
Native rules can't express your pricing or delivery logic
Shopify Functions developmentCheckout extensions
Checkout needs fields, validation or content it doesn't ship with
Checkout extensibilityERP & systems integration
Your store and back office hold different versions of the truth
Integration developmentWorkflow automation
People copy data between systems and chase status updates
Workflow automationMiddleware & APIs
Point-to-point connections break under volume and complexity
API developmentBuy, configure or build
The right answer isn't always custom. Here's how we decide with you.
| Approach | Use when |
|---|---|
| Existing app | A proven app already does exactly what you need. Cheapest and fastest, always our first check. |
| Configured app | An app is close, but needs setup, custom fields or theme work to fit your process. |
| Custom integration | Two or more systems must stay in sync and no reliable app connects them. |
| Custom app | The logic, admin tool or workflow simply doesn't exist in any app. |
| Middleware | High volume, complex mapping or many systems justify a dedicated layer between them. |
Systems we connect and capabilities we build
A working reference, not a limit. If a system has an API, we can usually connect it. Some checkout customisation requires Shopify Plus.

How we deliver
A technical project run like one, specified before it's built, tested before it ships.
Requirements workshop
We map what needs to connect, why, and what success looks like.
Systems audit
We review each system's API, limits, data model and access.
Data-flow design
We define what data moves where, in which direction and how often.
Technical spec
A written spec covering mapping, rules, error handling and edge cases.
Prototype
A working proof of the riskiest flow before full build.
Development
We build against staging, with logging and tests from day one.
UAT
You validate real scenarios against agreed acceptance criteria.
Deployment
Controlled release with rollback and monitoring in place.
Monitoring & support
Ongoing alerting, error handling and change requests.
Reliability & security
Integrations fail quietly when they're built carelessly. Ours are built to be observed, recovered and trusted.
- Least-privilege data permissions and scoped access tokens
- Authentication via OAuth and signed webhooks
- Rate-limit handling with retries and backoff
- Structured logging on every integration
- Monitoring and alerting on failed jobs
- Error recovery and safe re-processing
- Separate test and staging environments
- Controlled, versioned deployments
- Handling aligned with the Australian Privacy Principles
- Documentation handed over on every build
Investment
Cost tracks the number of systems connected and how custom the business logic is. Typical AU ranges:
Fixed-scope build
A single, well-defined integration or app scoped up front.
Discovery + implementation
Multi-system work, mapped and specified in a paid discovery, then built.
Milestone-based project
Larger programmes billed against agreed milestones.
Support & monitoring
Ongoing monitoring, error handling and change requests.
