The Client
The Romanian subsidiary of an international distribution group looking to implement the Standard Audit File for Tax (SAF-T) reporting requirement.
The Challenge
The Romanian entity operated within a centrally governed SAP environment configured with a global chart of accounts aligned primarily with IFRS reporting and internal management analytics. Transactional postings were automated through integrated modules covering procurement, sales and inventory processes.
While this setup ensured efficiency and consistency at group level, it introduced limitations in the context of SAF-T reporting. Local statutory classifications were not embedded in transactional logic, and fiscal reporting relied heavily on subsequent adjustments and reconciliations.
The Eurofast Solution
During the initial readiness assessment, the project team identified three critical risk areas: insufficient granularity of account classification for statutory reporting, inconsistent VAT configuration across business scenarios and weak data lineage between operational documents and accounting entries.
- Pilot extraction and reconciliation challenges
The first SAF-T pilot extraction was performed using a simplified mapping approach, whereby global general ledger accounts were aggregated into Romanian statutory account categories. Although technically feasible, this approach produced reconciliation discrepancies when comparing SAF-T journal entries with the local trial balance. The differences were not caused by system errors but by conceptual misalignment between global reporting logic and statutory accounting expectations.
- Redesigning the account mapping framework
To address these issues, the organisation implemented a layered mapping structure. At the first level, global accounts were mapped to statutory accounts. At the second level, additional analytical dimensions such as tax code classification, transaction type and partner category were incorporated into the transformation logic.
- Enhancing VAT configuration and transactional controls
SAF-T testing revealed configuration inconsistencies in VAT determination logic. The organisation implemented enhanced validation controls within SAP posting workflows and centralised responsibility for tax configuration maintenance.
- Strengthening data lineage and master data governance
Inconsistencies in supplier invoice references and customer transaction identifiers created challenges in populating SAF-T document fields. Master data fields were standardised and integration controls between operational modules and financial accounting were reinforced.
- Managing IFRS adjustments and reporting perimeter definition
A reconciliation bridge was established between consolidation adjustments and statutory ledgers to ensure SAF-T files reflected locally relevant accounting data.
- Technology architecture and implementation approach
The organisation adopted a hybrid architecture combining SAP data extraction with transformation and validation logic implemented in a reporting layer. This enabled iterative testing and reduced the need for disruptive ERP configuration changes.
- Project outcomes and finance function impact
Following implementation, the organisation achieved stable SAF-T submissions with significantly reduced manual intervention. Chart of accounts ownership was clarified, VAT controls were enhanced and collaboration between finance, tax and IT teams became more structured.
The Impact
This case study demonstrates various key technical lessons for finance and tax leaders, including:
- SAF-T readiness depends on conceptual alignment between global ERP logic and statutory reporting requirements
- Account mapping should be designed as a controlled governance framework
- VAT configuration discipline and posting validation controls are critical
- Strong data lineage reduces reconciliation complexity
- Scalable technology architecture enables sustainable compliance
Preparing for the future of digital tax reporting
The Romanian SAF-T experience demonstrates that organisations willing to invest in accounting translation, data governance and process integration can transform regulatory pressure into strategic advantage.
