THE PROBLEM
The 2024 tax reform introduced new tax categories (IBS, CBS, IS) that had to be applied correctly to every electronic invoice — in a regulated environment where an invalid document has direct financial and legal impact.
THE APPROACH
A validation-first pipeline: invoices are parsed on intake, run through a rule engine encoding the new fiscal model, persisted to Oracle with a full audit trail, and reconciled against SEFAZ and MasterSAF endpoints.
ENGINEERING NOTES
- Validation rule engine for IBS / CBS / IS tax codes under the 2024 reform
- Handles a high daily volume of NF-e documents with compliance guarantees
- Integrated with SEFAZ and MasterSAF API endpoints
- Oracle pipelines with full audit trail and consistency checks
