SAP Integration for eCommerce & Custom Platforms
S/4HANA and Business One connected to Shopify, Adobe Commerce, and custom platforms, built around SAP's reality rather than a vendor demo.
SAP is where a lot of large Australian businesses run their operations, and it is also where a lot of eCommerce integrations quietly struggle. The APIs are powerful and unforgiving, the data model is deep, and S/4HANA and Business One are genuinely different products with different integration paths. I build the connection between SAP and your storefront the same way I build every integration: designed around the failure modes first, with retries, idempotency, reconciliation, and monitoring, so it keeps working as volume grows rather than falling over the first busy week.
& custom builds
My integration track record
I run ERP integrations in production against Options ERP, NetSuite, MYOB, and Xero, including a nightly sync of around ten million rows at 100% success. SAP is the same class of integration at the top of the market, and I approach it the same way: design for the failure modes, not the demo.
What I build with SAP
The SAP integration work I most often take on. If yours sounds like one of these, we should talk.
S/4HANA & Business One
These are different products with different APIs, capabilities, and integration approaches. S/4HANA is the enterprise suite; Business One is aimed at smaller operations. I establish which one you run, and what it can actually do, before scoping the work.
Orders, Inventory & Pricing
Orders into SAP, stock levels and customer-specific pricing back out to your storefront, and invoices reconciled. The round trip is what matters: an order that reaches SAP but never reports status back is still a support ticket.
The Right Integration Path
OData services, the SAP Cloud Platform, BAPIs, or middleware, depending on your landscape. Choosing badly here is how SAP integrations become brittle and expensive to change. I pick the approach that fits how your SAP is actually deployed.
Monitoring & Reconciliation
Retries, idempotency, alerting, and reconciliation from day one. With a system as central as SAP, a silent sync failure is not a bug, it is a business incident, so it gets caught before anyone downstream notices.
A SAP integration built to last
The same approach behind every integration I ship, from the first conversation to the years of maintenance that follow.
Scope & map
We map exactly what needs to move between SAP and your store: orders, stock, pricing, customers, and where the awkward edge cases hide.
Build for redundancy
I build the integration around the failure modes: retries with backoff, idempotent writes, and reconciliation, so it holds up when the API has a bad day.
Test & reconcile
Tested against real data in a safe environment, with reconciliation reporting that proves SAP and your store actually agree before go-live.
Monitor & maintain
Monitoring and alerting from launch, so failures surface immediately, and the same developer who built it is the one who keeps it running.
Where SAP fits in
The services and platforms a SAP integration most often plugs into.

Laravel Development
Laravel is PHP's leading framework, and I've been shipping production Laravel since version 4 in 2013.
AWS Cloud Management
Amazon Web Services offers reliable, scalable, and inexpensive cloud computing services.
With SAP, the demo was never the hard part.
SAP integrations reward people who plan for the hard days and punish people who follow the happy path. I treat the integration as the heart of the project, because with SAP it genuinely is: it sits between your storefront and the system your business runs on, and it has to be engineered for the failures so it keeps running reliably for years.
A typical agency
Integration as an afterthought.
-
A junior follows an SAP tutorial, ships the happy path, and never accounts for how your specific SAP landscape is deployed.
-
No retries, no idempotency. A timeout mid-request duplicates an order or drops it entirely.
-
When a sync fails it fails silently, and with SAP that means a real operational problem before anyone notices.
Working with me
Integration as the specialism.
-
I establish which SAP product and deployment you run, pick the right integration path, and design for volume and failure from the start.
-
Idempotent writes and retries with backoff. A retry resolves to the same result rather than a duplicate or a gap.
-
Monitoring and reconciliation surface failures immediately. The same developer who built it is the one who fixes it.

Common SAP Integration Questions
Can SAP integrate with Shopify?
Yes. Orders, inventory, customer-specific pricing, and invoices can all flow between SAP and Shopify, Adobe Commerce, or a custom storefront. The shape of the work depends on whether you run S/4HANA or Business One and how your SAP is deployed, which is the first thing I establish.
What's the difference between SAP S/4HANA and Business One for integration?
They are different products aimed at different sizes of business, with different APIs and capabilities. S/4HANA is the enterprise suite and typically integrates via OData services and the SAP Cloud Platform. Business One is aimed at smaller operations and has its own service layer. An approach designed for one does not simply transfer to the other.
Do you use middleware or connect to SAP directly?
It depends on your landscape. Sometimes a direct API integration is cleanest; sometimes you already have middleware or an integration platform that it makes sense to work through. I choose based on how your SAP is actually deployed and what you already run, not on a fixed preference.
How long does an SAP integration take?
SAP integrations are typically larger projects than a Xero or MYOB integration, because the systems are bigger and the requirements usually more complex. A focused sync is measured in weeks; a full two-way integration with contract pricing and multi-location inventory is measured in months. The scope depends on how customised your SAP already is. Once that is defined, I can provide an accurate estimate.
