TransArt v2 (expansion) and SAF-T D406: automating D300/D394 reconciliation, ROI 2026
SAF-T D406 requires reconciliation with D300 (VAT) and D394 (purchases/sales). How TransArt v2 (expansion) generates SAF-T and how SAF-T Reconciler reduces effort from 40h/month to 3h/month.

The SAF-T D406 Context in RO
SAF-T D406 (Standard Audit File for Tax) is the mandatory periodic tax filing for all large enterprises (since 2022) and mid-market companies (phased in 2023-2026). It contains detailed data on:
Chart of Accounts (Section 1)
Customers + Suppliers (Section 2)
Stocks + Items (Section 3)
Fixed Assets (Section 4)
General Ledger Transactions (Section 5)
Sales Invoices (Section 6)
Purchase Invoices (Section 7)
Stock Movements (Section 8)
How TransArt v2 (expansion) generates SAF-T D406
TransArt v2 (expansion) includes a native SAF-T module that:
1. Extracts data from GL, AR, AP, and Inventory modules
2. Maps the internal Chart of Accounts → RAS taxonomy of ANAF (the Romanian tax authority)
3. Generates the XML file according to the D406 schema
4. Validates against the XSD schema
5. Uploads to the ANAF SPV portal
The Real Challenge: D406-D300-D394 Reconciliation
ANAF performs automatic cross-checks between:
D406 (SAF-T) — the ultimate source of truth
D300 (Monthly VAT return) — total collected / deductible VAT
D394 (Domestic sales/purchases) — transaction list
If these three do not match → audit red flag. Companies currently allocate 40-60h/month of the Chief Accountant's time for manual reconciliation:
Exact match between SAF-T Section 6 (Sales) and D300 Collected VAT
Exact match between SAF-T Section 7 (Purchases) and D300 Deductible VAT
Match between SAF-T Section 5 (Transactions) and D394 domestic filings
Match between SAF-T Section 8 (Stock) and the end-of-period stock balance
Why native TransArt v2 (expansion) is not enough
TransArt v2 (expansion) generates each declaration separately, but does not perform cross-checks between them. The native module:
Generates D406 ✓
Generates D300 ✓
Generates D394 ✓
Does not reconcile them against each other ✗
Azuvio SAF-T Reconciler
The SAF-T Reconciler runs before the ANAF submission as a cross-check layer:
VIES/Tax ID validator (active / struck off / inactive status)
RAS taxonomy mapper (TransArt v2 (expansion) chart of accounts → ANAF codes)
Cross-check D406 ↔ D300 (VAT per rate)
Cross-check D406 ↔ D394 (domestic sales/purchases)
Stock-document linkage (stock movements ↔ Goods Received Note/Dispatch Note/Invoice)
Payment-invoice matching (receipts/payments ↔ invoices)
Discrepancy Dashboard with real-time alerts + suggested auto-fixes
ROI of SAF-T Reconciler for TransArt v2 (expansion)
For a company with 2,500 invoices/month:
Time before: 40-60h/month manual reconciliation
Time after Reconciler: 3-5h/month review + approval
Savings: 35-55h/month = €17-26k/year
Audit risk: drops dramatically (zero red flags)
Reconciler cost: ~€12-24k/year subscription
Year 1 ROI: 1.5-2.5x + reduced compliance risk
Verdict
TransArt v2 (expansion) generates the SAF-T file. Azuvio SAF-T Reconciler automates the cross-checks that the tax authority performs automatically — eliminating audit red flags and 40+ hours/month of manual labor.
