AI-driven end-to-end tax compliance automation

Book a demo

Fonoa AI Agents are purpose-built AI agents that execute the full indirect tax compliance lifecycle autonomously. Humans set the rules and approve exceptions. Agents handle everything else.

Autonomous tax execution. Human oversight.

End-to-end workflow automation

Agents monitor transaction flows, trigger validations, submit invoices, prepare returns, and file — all without manual intervention.

Exception-based escalation

Agents handle routine compliance automatically and only escalate genuine exceptions to your team for review and approval.

Connected to your full tax stack

Agents operate across the entire Fonoa AI platform — Validate, Tax Engine, E-Invoicing, Returns, Knowledge, and Audit — as one unified system.

Configurable rules and guardrails

Your tax team defines the rules. Agents execute within those guardrails and learn from every decision your team makes.

Full audit trail on every agent action

Every action an agent takes is logged with full context. Complete transparency at all times.

Proactive compliance monitoring

Agents don't just execute — they monitor. They surface risks, flag anomalies, and alert your team before issues become problems.

The future of indirect tax compliance.

What Agents will do for you

Autonomous return preparation and filing

Agents collect transaction data, reconcile against e-invoices, prepare multi-country returns, and file — automatically, on schedule.

Real-time compliance monitoring

Agents continuously scan your transaction flows for anomalies, missing validations, and compliance risks.

Regulatory change deployment

When Knowledge detects a rule change, Agents automatically update the relevant workflows and flag any transactions that need review.
