What to validate
- Legal-entity mapping: Identify all in-scope invoicing entities and transactions.
- Master data: Review customer and supplier identifiers, addresses and mandatory fields.
- Invoice lifecycle: Identify invoices, notes, cancellations, corrections and rejections.
- Provider integration: Document API, file-transfer, connector and authentication requirements.
- Controls: Agree ownership of data quality, exception handling and reconciliation.
- UAT: Test normal and exceptional transactions with business stakeholders.
- Continuity: Establish backup processes for outages and operational support escalation.
Systems to include in scoping
SAP, Oracle, Odoo, Microsoft Dynamics, Zoho, Tally and internally developed applications all require solution-specific assessment. Inclusion here does not imply verified compatibility with any accredited provider.
A realistic implementation workstream
Document the current invoicing flow, assess mandatory data fields against the latest official specifications, shortlist integrators, run a proof of concept, establish exception-handling controls and conduct business-user signoff.
