Enterprises & Integrations
Financial, ERP, tax-mandate and point-of-sale connectivity across the enterprise core.
What we do
XSIS Enterprises & Integrations removes the silos between ERP backbones, banking infrastructure, tax authorities and physical and digital commerce. We implement, customise and synchronise Tier-1 and composable ERPs, including SAP S/4HANA and BTP, Oracle Fusion and NetSuite, Microsoft Dynamics 365 and Odoo, with data integrity across orders, inventory and general ledgers.
Our financial integration specialists build host-to-host banking connectivity (SWIFT, EBICS, ISO 20022 pain, camt and pacs), automated multi-currency treasury reconciliation, and real-time POS, SoftPOS and Agent Payments Protocol (AP2) checkout pipelines, alongside compliance with national e-invoicing mandates across MENA, Europe and APAC.

How we build every connection
We connect ERP systems to banks, card networks, POS and third-party services. Each connection uses the standard its partner expects, is tested with that partner, and has a path for every failure.
Specify before building
Every interface starts as a written specification: fields, formats, timing, volumes and error codes, agreed with you and your partner.
Test with the real counterpart
We test against each bank’s, acquirer’s or provider’s test environment, and keep the evidence for your auditors.
No silent failures
A message that fails is retried, queued or handed to a person, with an alert. Nothing disappears.
Reconcile what moved
What left one system is matched with what arrived in the other, and every difference is shown to someone who can act on it.
Observable in production
Dashboards and alerts show volumes, delays and errors for each connection, so problems are found before your partners call.
Documented and handed over
Mappings, runbooks and test evidence come with every connection, so your own team can run it.

The ERP at the centre, every connection monitored
Banks, stores, payment networks and third parties connect to the ERP through one integration layer. Anything that fails lands in a queue with an alert, never in silence.

The flow in 10 steps
The flow, step by step
- From ERP to Integration layer: Orders, invoices and payment runs, over REST/JSON · OData · IDoc (primary flow).
- From Integration layer to Banks: Payment files, over ISO 20022 pain.001 · SFTP H2H (primary flow).
- From Banks to Integration layer: Statements, over camt.053 · MT940 (asynchronous).
- From POS and stores to Integration layer: Sales and returns, through an event queue, over REST/JSON (asynchronous).
- From Integration layer to POS and stores: Prices and stock, over REST/JSON (primary flow).
- From POS and stores to Payment gateway and acquirer: Card authorisation, over ISO 8583 (primary flow).
- From Payment gateway and acquirer to Integration layer: Settlement files, over SFTP (asynchronous).
- From Integration layer to Third parties: Customers, shipments and tax documents, over REST · SOAP · webhook (primary flow).
- From Integration layer to Monitoring and exception queue: Failed messages, to a dead-letter queue (exception path).
- From Monitoring and exception queue to Your operations team: Alerts and breaks to resolve (exception path).

Proof in production
We connected SAP S/4HANA to regional banks and tax authorities for a Tier-1 GCC bank and conglomerate. For a GCC retail group, we synchronised store terminals, storefronts and the ERP in real time.
Case studies
- 99.4% straight-through processing on automated camt.053 bank statement reconciliation
Automated ISO 20022 host-to-host treasury and real-time tax clearance engine
How a Tier-1 GCC commercial bank connected SAP S/4HANA to its banking rails over ISO 20022 and cleared every e-invoice with ZATCA and PINT-AE in real time.
- under 250 ms SKU inventory sync across 800+ POS terminals and the digital storefronts

How to start
The Mandate E-Invoicing and ERP Readiness Sprint is the quickest entry. A failing or undocumented integration starts with the Brownfield Diagnostic Bridge, and clear requirements go straight to a proposal.
What happens next
Pre-consulting session
A free 30-minute online pre-consulting session: we go through your goals, systems and constraints.
Readiness review
In a free 48-hour readiness review, a Principal Architect checks your project against the 6-point Definition of Ready and recommends the track that fits.
Choosing the track
Scope-ready projects receive a binding proposal within 3–5 business days. Concept-stage projects start in the Blueprint Studio. A live system that is failing, undocumented or needs integration starts with a diagnostic of 1–2 weeks. The Blueprint Studio and the diagnostic each have a fixed fee, quoted in the proposal.
Delivery in five stages
Mobilisation, sprints with live demonstrations, integration and hardening, acceptance and go-live, then managed services. After launch comes a warranty period, then optional support and maintenance.
Embedded specialists and strategic augmentation
Nearshore and on-site principal engineers and specialists, and embedded solution, transformation, PQC and integration architects.
Fixed-outcome projects and round-the-clock managed services
Fixed-scope, milestone-driven delivery with named delivery leads, and round-the-clock application managed services under SLA governance.
The quickest way in is the Mandate e-invoicing and ERP readiness sprint package, one of our rapid engagement packages.
Questions and answers
Why treat integration as a separate discipline?
Because most failures happen between systems, not inside them. A payment file a bank rejects, an invoice a tax authority refuses or a sale the ERP never receives costs money at once. We give every interface a contract, tests, monitoring and a path for every failure.
Which deadlines should we plan for?
The ones in your markets: Saudi ZATCA Phase 2 waves and the UAE e-invoicing programme in MENA, ViDA and digital product passports in the EU, banks' moves to ISO 20022, and the end of SAP ECC support. We map them against your systems in a readiness sprint.
Can you work with our ERP partner or middleware?
Yes. We often work beside the partner that implemented your ERP, and we build on the integration platform you already own. We agree who owns each interface, so nothing falls between two suppliers.
How do you make sure nothing is lost or posted twice?
Every write is idempotent and every failure goes to a dead-letter queue with a person responsible for it. The contract backs this with milestone acceptance gates and a post-launch defect warranty.
