Moving to e-Invoicing involves more than registering on a platform.
For many businesses, the real work begins with understanding whether existing invoice data, ERP systems, accounting software and internal processes are ready to connect to Nigeria’s e-Invoicing environment.
This is where implementation support becomes important.
Through Vi-M and eNvoice, businesses can move through the implementation process in a structured way, from assessing readiness to integration, APP connectivity, testing, training and ongoing operation.
1. Readiness Assessment
Every implementation should begin with the existing invoicing environment.
We review how invoices are currently generated and identify the systems, processes and data that will need to support e-Invoicing.
This can include:
- ERP or accounting software;
- customer and supplier data;
- tax and classification codes;
- invoice fields;
- credit and debit note processes;
- payment information; and
- existing approval and control workflows.
The objective is to identify gaps before integration begins.
2. System and ERP Integration
Businesses do not necessarily need to replace the systems they already use.
Vi-M supports the connection of existing ERP, accounting and invoicing environments to the e-Invoicing framework.
Depending on the organisation, this may involve ERP integration, accounting-software integration, APIs, middleware, batch uploads or another suitable implementation route.
The focus is to enable compliant invoice information to move from the organisation’s existing business systems into the required e-Invoicing workflow.
3. APP Connectivity
Implementation also requires the secure exchange of invoice information within the regulated e-Invoicing environment.
As an accredited Access Point Provider, Vi-M/eNvoice supports the connectivity required for invoice validation, signing, transmission, exchange, status tracking and related compliance workflows.
Businesses that already have their own internal technology or System Integration capability can also use eNvoice specifically for APP connectivity.
4. Testing Before Go-Live
Integration should not move directly from development into live operations.
The implementation process includes testing invoice data, mappings, validation rules, transmission workflows, responses and exception handling.
This helps identify issues before they begin affecting normal business operations.
Testing may include:
Create → Validate → Transmit → Receive Response → Correct Exceptions → Retest
The goal is to ensure that the complete invoice journey works reliably before full deployment.
5. User Training
Technology alone does not make an implementation successful.
Finance, tax, IT, billing and other relevant users need to understand how the new process affects their responsibilities.
Vi-M provides implementation and user training covering areas such as invoice processing, exception management, credit and debit notes, payment updates, status monitoring and relevant administrative controls.
This helps the organisation move from technical implementation to practical day-to-day use.
6. Moving Into Ongoing Compliance
Go-live is not the end of the implementation journey.
Businesses still need visibility over invoice transmission, exceptions, status updates and changes that may affect their e-Invoicing processes.
eNvoice provides a structured environment for managing these workflows while Vi-M supports the wider tax, regulatory, technology and enterprise considerations surrounding implementation.
One Implementation Journey. Multiple Entry Points.
Not every organisation starts from the same place.
A business may need:
Readiness Support | ERP Integration | Accounting Software Integration | API Integration | SI Support | APP Connectivity | SI + APP | Testing | Training
The appropriate route depends on the organisation’s existing systems and operational requirements.
The objective is not simply to “connect to e-Invoicing.”
It is to establish an invoicing process that is connected, compliant and workable within the organisation’s existing operations.
