01
Inventory as one master
SAP S/4HANA owns stock; levels and cost prices propagate to every channel in near real time with per-channel buffer rules.
Outcome: oversells and safety-stock hoarding both fall.

SAP S/4HANA API integration and platform bridging
We connect SAP S/4HANA to the systems your business already runs on — accounting, ERP, warehouse, CRM and courier platforms — so that purchase orders, stock valuations and nominal codes move between them without manual intervention.
Fixed-scope engagements, delivered by UK-based integration engineers. Documentation and source code handed over on completion.
- ✓OData v2/v4 APIs
- ✓Event enablement
- ✓IDoc & BAPI bridging
What we can connect SAP S/4HANA to
SAP S/4HANA holds stock, orders, products and financial records. Every other system in the business holds a partial copy of the same data. Our role is to make one the source of truth and keep the rest aligned — through the SAP S/4HANA API, webhooks where they exist, and a bridging layer where the other system has no usable interface of its own.
Ecommerce and storefronts
Publish products, prices and stock from SAP S/4HANA to your sales channels, and pull orders and customers back into one order book.
Shopify, WooCommerce, Magento, BigCommerce
Accounting and finance
Where finance runs on a separate ledger, keep SAP S/4HANA and the accounts agreed on invoices, payments and nominal codes.
Sage, Xero, QuickBooks, Sage Intacct
Warehouse and 3PL
Send picks, putaways and shipments between SAP S/4HANA and the warehouse system, with confirmations and stock adjustments written back.
Mintsoft, Peoplevox, SnapFulfil
CRM and sales
Give sales live stock, pricing and order status from SAP S/4HANA inside the CRM, and push quotes and won deals back as orders.
Salesforce, HubSpot, Dynamics 365 Sales
Marketplaces
Consolidate Amazon and eBay demand into SAP S/4HANA with per-channel buffers and a single fulfilment pipeline.
Amazon SP-API, eBay
Bespoke, EDI and legacy systems
Production lines, EDI trading partners and older databases connected through a controlled layer that speaks both sides.
EDI (EDIFACT/X12), SQL Server, SFTP, SOAP
Common SAP S/4HANA integration use cases
Each is a defined, testable data flow rather than an open-ended development project.
02
Order ingestion pipeline
Orders from web, marketplace and EDI are normalised and created in SAP S/4HANA with allocation in payment order.
Outcome: one queue, consistent SLAs.
03
Product data publishing
Catalogue, variants, media and pricing maintained in SAP S/4HANA and pushed on change to the storefront and marketplaces.
Outcome: the catalogue is maintained once.
04
Finance handoff
Invoices, credits and payments move between SAP S/4HANA and the ledger against a field-level ownership map.
Outcome: a clean close, no double entry.
05
Warehouse round trip
Shipments, tracking and stock adjustments flow between SAP S/4HANA and the WMS or 3PL with idempotent confirmations.
Outcome: accurate stock and customer notifications.
06
EDI trading partners
Retailer EDI (orders, ASNs, invoices) translated to and from SAP S/4HANA documents with validation and acknowledgements.
Outcome: chargebacks from format errors removed.
How a SAP S/4HANA API integration is delivered
Four stages, fixed scope agreed before any code is written. Typical delivery for a single-system integration is two to four weeks.
Stage one
Discovery and data mapping
We document the systems involved, the direction of each flow, and every field that must move — including the awkward ones such as tax, discounts and multi-currency.
Output: written integration specification.
Stage two
Fixed scope and estimate
The specification becomes a fixed-price proposal with a delivery schedule and defined acceptance criteria. No time-and-materials open ends.
Output: costed scope for sign-off.
Stage three
Build and testing
Development against a SAP S/4HANA development or sandbox environment and a sandbox of the destination system, with your own data used for acceptance testing.
Output: tested integration and test evidence.
Stage four
Go-live and handover
Controlled cutover with monitoring in place, followed by handover of code, credentials and documentation, and a period of hypercare support.
Output: live integration, owned by you.

Request a scopeSAP S/4HANA API bridging when there is no direct connector
A generic connector works until the moment your setup differs from the demo — a custom field, a second warehouse, a system on the other end with no API at all. At that point the integration has to be built around your actual data, not a vendor's assumption of it.
In practice that means a queue that absorbs traffic spikes, retries failed calls against the SAP S/4HANA OData & SOAP APIs (API Hub) rate limits, and a log of every transaction so a disputed record can be traced end to end. When SAP S/4HANA changes its API, only the bridge needs updating — not every downstream system.
If there is no usable interface at all, the fallback is a flat-file exchange, a direct database connection, or a small REST wrapper we write and host ourselves — whichever fits what is actually there.
Included in every bridge we build
- →Error handling with alerting when a transfer fails
- →Automatic retries that respect the platform API rate limits
- →A transaction log for tracing any individual record
- →Idempotency so a repeated event cannot create a duplicate
- →Field-level mapping documentation you can hand to any developer
- →A staging environment that mirrors production
SAP S/4HANA integration FAQs
A single-direction integration between SAP S/4HANA and one business system is typically delivered in two to four weeks, including discovery, field-level mapping, build against a sandbox, acceptance testing with your own data and supported go-live. Multi-system programmes are phased.
You do. Source code, credentials, configuration and documentation are handed over on completion, and there is no licence fee for continuing to use it. Monitoring and change support are available under a separate agreement.
Platform APIs are versioned and change on their own schedule. Integrations under a support agreement are reviewed each release cycle and migrated ahead of deprecation dates; for handed-over work the version dependencies are documented so your team can plan.
Yes. Where the other side has no modern API we bridge it — scheduled file exchange over SFTP, a database-level connector, or a middleware layer that exposes a documented REST interface to SAP S/4HANA while speaking the legacy system's own protocol behind it.
Other platforms we integrate
Each platform has its own integration guide covering authentication, available endpoints and typical data flows.
