Shopify Retail Integrations Built for Australian Stores

For AU retailers running Shopify POS across multiple locations. We connect point of sale, inventory, shipping and accounting into one system that reconciles, so stock, orders and ledgers stay accurate without anyone re-keying the difference.

Typical integration build

When your systems don't talk, someone re-keys the difference

Retail runs on the join between your till, your warehouse and your ledger. When those aren't wired together, the gaps surface as oversells, stale stock and a finance team reconciling by hand.

Stock drifts between channels

In-store sales and online orders draw on the same stock, but the counts diverge, so you oversell online or sit on phantom inventory.

Orders re-keyed into accounting

Sales, refunds and payouts get typed into Xero or MYOB by hand, which is slow and quietly wrong by month-end.

Shipping lives outside Shopify

Carrier rates, labels and tracking sit in a separate tool, so fulfilment staff copy addresses and chase parcels across tabs.

No single view across stores

Each location reports its own numbers and head office stitches them together in a spreadsheet.

Admin scales with orders

Every extra order adds manual work instead of margin, because the back office was never automated.

Who this is for

A fit if you're

An AU retailer running Shopify POS across two or more stores
Syncing online and in-store stock from a single catalogue
Reconciling Shopify sales into Xero, MYOB or QuickBooks
Wanting carrier, 3PL and warehouse data inside Shopify
Replacing a fragile stack of one-off connectors that disagree

Not a fit if you're

A single-store shop happy with native Shopify POS and apps
Not on Shopify, or unwilling to move to it, we are Shopify-only
After a full custom ERP built from scratch
Needing a same-week patch rather than a durable integration

What retail integration includes

Scoped to the systems in play after discovery. A typical engagement spans these three areas.

What's included

Discovery of your systems, data flows and reconciliation rules
POS-to-online inventory sync from one source of truth
Order, refund and payout sync into your accounting platform
Shipping and carrier integration inside Shopify
Error handling, retries and alerting on every sync
Documentation and a handover your team can run

Technical deliverables

Custom middleware or a private app linking Shopify to your back office
Webhook and API integration with idempotent, logged jobs
Field mapping, transforms and de-duplication logic
Staging environment and a reconciliation test suite
Monitoring dashboard with failure alerts

Technology & integrations

Shopify POS, Admin and Storefront APIs
Xero, MYOB and QuickBooks for accounting
Cin7, DEAR and Unleashed for inventory and 3PL
Australia Post, Sendle and StarShipit for shipping
Klaviyo, ERP and CRM syncs where needed

How we run an integration

A staged build that never touches live data until it reconciles to the cent.

Discovery & systems audit

We map every system, data flow and reconciliation rule, and agree the single source of truth. (Week 1)

Integration design

We spec the connectors, field mappings and error handling, then confirm scope in writing. (Week 1–2)

Build in staging

We build the middleware and syncs against a staging store, isolated from your live data. (Week 2–5)

Reconciliation testing

We run real data through and reconcile to the cent before anything reaches production. (Week 5–6)

Go-live

We cut over in a quiet window, monitor closely and verify the first live syncs. (Week 6–7)

Handover & support

You get documentation, monitoring access and 30 days of post-launch support. (Week 7–8)

Controls we build in

Integrations fail quietly. These controls make failures visible and recoverable.

Idempotent jobs, so a retry never double-posts an order
Every sync logged with a traceable audit trail
Automatic retries with alerting when a job can't recover
Reconciliation reports that flag mismatches before finance does
A staging environment that mirrors production data flows
WCAG 2.1 AA on any customer-facing surface we touch

Investment

Priced after discovery and scoped to the systems in play. Typical, indicative bands:

Number of systems and directions of syncWhether an off-the-shelf connector fits or custom middleware is neededOrder and SKU volume, and reconciliation complexityNumber of store locations and carriersHistorical data migration and clean-up

Single integration

$6,000–$12,000

One connection, e.g. Shopify to Xero, with mapping and monitoring.

Multi-system integration

$12,000–$28,000

POS, inventory, shipping and accounting wired to one source of truth.

Custom retail platform

$28,000–$60,000+

Bespoke middleware across many stores, systems and carriers.

Retail integration FAQs

Yes. You own the middleware, the connectors and all documentation outright on final payment. There's no lock-in to us.

Most run 4–8 weeks, depending on the number of systems and reconciliation complexity. We confirm a firm timeline after discovery.

Yes. We integrate around your current stack and only replace a connector when it's the cause of the problem, agreed with you first.

Xero, MYOB and QuickBooks are the common ones for AU retail. We can integrate others through their API where one exists.

Yes. Multi-location stock from a single source of truth is the core of most retail integrations we build.

Jobs retry automatically and alert both of us when they can't recover. Nothing double-posts, and every sync is logged for audit.

You get 30 days of post-launch support, monitoring access and documentation. Ongoing support and enhancements run on a retainer.

We can migrate and reconcile historical orders and stock as a scoped add-on, and we'll flag during discovery whether it's worth doing.

Yes. We integrate common AU inventory and 3PL systems like Cin7, DEAR and Unleashed, and custom warehouses via their API.
