System Integrator & Access Point Provider Services

Connect Your Business Systems to e-Invoicing Infrastructure - Properly.

Vi-M supports enterprises across the technical and compliance journey required to connect ERP, accounting and transaction systems to fiscal e-Invoicing workflows — from data mapping and integration through validation, transmission, exception management and post-go-live support.

System Integrator (SI) Connects enterprise source systems, data and business processes into the e-Invoicing implementation flow.
Access Point Provider (APP) Provides the secure connectivity layer used to exchange compliant invoice data within the fiscal e-Invoicing environment.
Vi-M's role Brings tax, finance, ERP, integration and operating-process perspectives together so the connection works beyond go-live.
Beyond accreditation

Implementation Depends on More Than Having Access to the Platform

A successful e-Invoicing implementation must connect the regulatory requirement to the way the business actually creates, approves, adjusts, records and reports transactions. That means understanding both the technology pathway and the accounting, tax and operational processes behind the invoice.

01

Business Process

How invoices, credit notes, debit notes, payments, cancellations and exceptions move through the organisation.

02

Systems & Data

How ERP, accounting, billing and operational systems produce the data required for structured fiscal reporting.

03

Fiscal Connectivity

How compliant invoice data is validated, transmitted, tracked and reconciled across the e-Invoicing chain.

Integration capability

What Vi-M Supports

Our implementation approach is designed around the full transaction and reporting lifecycle rather than treating e-Invoicing as a stand-alone technical connection.

A

ERP & Accounting Integration

Connectivity with source systems used to create and record invoice transactions.

B

Invoice Data Mapping

Mapping customer, supplier, item, tax, quantity, totals and other required fields into the structured invoice model.

C

Validation & Business Rules

Configuration and testing of required data, tax treatment, transaction logic and validation responses.

D

Adjustments & Invoice Lifecycle

Support for credit notes, debit notes, payment status, reversals and the relationship between connected transactions.

E

Secure Transmission

Structured connectivity, authentication, routing and controlled exchange of invoice data through the implementation environment.

F

Exceptions, Logs & Reconciliation

Visibility into transmission failures, validation errors, rejected transactions and post-submission reconciliation.

System Integrator services

Connect e-Invoicing to the Systems Your Business Already Uses

As System Integrator, the focus is not simply on sending invoice data. It is on making sure the business source systems, transaction processes and required fiscal data are correctly aligned before that data enters the e-Invoicing environment.

Typical SI Workstreams

  • Source-system and process discovery
  • Invoice-data mapping and transformation
  • API or middleware integration design
  • Tax and transaction-rule configuration
  • Sandbox testing and validation
  • Exception handling and reconciliation design
  • Production deployment and post-go-live support

What the APP Layer Must Support

  • Secure system-to-system connectivity
  • Structured invoice transmission
  • Authentication and access controls
  • Transaction status visibility
  • Error and exception reporting
  • Logs and traceability
  • Operational support for connected integrations

A Reliable Connectivity Layer Between Systems and the Fiscal Environment

The APP layer is part of the operational chain through which structured invoice information is exchanged. For enterprises and System Integrators, this requires more than a technical endpoint: connectivity must be secure, traceable and supportable when transactions fail or require investigation.

Choose the right pathway

Different Businesses Need Different Integration Models

The right implementation model depends on the maturity of your existing systems, transaction volumes, internal IT capability and how much of the e-Invoicing workflow you want to manage within your own environment.

Implementation lifecycle

From Discovery to Stable Operations

We structure implementation so that technical connectivity, business-process accuracy and fiscal reporting are tested together before production.

1 Readiness & Discovery

Review systems, invoice processes, data and internal responsibilities.

2 Mapping & Solution Design

Define fields, transaction flows, integration pathway and exception logic.

3 Build & Configuration

Develop or configure the required connection, transformations and controls.

4 Testing & Validation

Test invoice scenarios, adjustments, responses and error handling.

5 Go-Live

Move the approved integration into production with monitored deployment.

6 Operate & Support

Monitor transactions, resolve exceptions and maintain compliance continuity.

Governance by design

Connectivity Should Not Weaken Control

E-Invoicing introduces a new digital reporting layer into existing finance and transaction processes. Implementation should therefore preserve appropriate access, traceability, reconciliation and oversight.

✓

Access Control

Roles and permissions aligned with operational responsibilities.

✓

Audit Trail

Traceable transaction events, responses, changes and exceptions.

✓

Reconciliation

Ability to compare source-system records with fiscal transmission status.

✓

Operational Monitoring

Visibility into failed, pending, rejected and successfully processed transactions.

Strong integration begins with strong data.

If customer, supplier, item, tax or transaction data is inconsistent at source, integration can simply transmit the inconsistency faster. Data and control readiness should therefore be assessed alongside the technology. Explore Tax Data & Controls Review →
