AP Digital Services, a technology and consulting company specializing in digital services, is launching an Artificial Intelligence-based solution that reduces the time for changes to the National Registry of Legal Entities (CNPJ) by up to 98% (from 10 to 12 weeks to 2 to 6 hours), as stipulated in the Tax Reform, which will come into effect in January 2026.
Entitled ModernizeAI, the solution automates the identification, modification, and validation of CNPJ (Brazilian taxpayer ID) usage in legacy systems within a specified timeframe and ensures 100% compliance with new tax regulations, avoiding fines that can reach R$ 50 million.
“The new rules regarding the CNPJ format impose a complex technical and regulatory adjustment on corporate systems. Systems that are not prepared may experience operational disruption when the change takes effect, causing critical problems in processes,” says Luciana Miranda, COO and CMO of AP Digital Services.
Technology integrated into ModernizeAI
ModernizeAI offers an end-to-end automated solution, without manual intervention, using 16 Artificial Intelligence agents that work collaboratively to modernize companies' CNPJs (Brazilian corporate tax IDs):
- Analysis team: nine agents are responsible for secure repository cloning, configuration extraction, file discovery and prioritization, and architecture analysis.
- Implementation team: seven agents are responsible for implementation planning, automatic generation of modernized code, data migration, creation of automated tests, and final compliance validation.
“With automated identification of 100% of CNPJ usage points across heterogeneous database platforms, updated technical documentation, and constant post-implementation monitoring, ModernizeAI eliminates manual effort and increases company productivity,” highlights Luciana Miranda.
Measurable benefits of ModernizeAI
In addition to reducing the time for CNPJ change processes by up to 98%, other benefits provided by ModernizeAI include:
- Accuracy in pattern detection: the solution has a 95% accuracy rate in detecting CNPJ patterns, with no false negatives.
- Cost reduction: the solution reduces the investments required for CNPJ (Brazilian company tax ID) changes by up to 85%, including professionals and technical infrastructure.
- Security and control: the solution has features for automatic backups and versioning that ensure data traceability and recoverability.
“Our mission is to transform the digital future of companies, enabling them to adapt to new regulations efficiently and without risk during this time of great uncertainty surrounding the Tax Reform. Our goal is to give technology teams the predictability needed for the change of CNPJ (Brazilian company tax ID),” concludes the COO and CMO of AP Digital Services.
