About Finzo AI
Finzo AI is a financial intelligence platform that replaces manual financial operations with autonomous AI agents.
AI agents connect to your existing ERP and bank accounts and take over accounts payable, accounts receivable, GST and TDS compliance, bank reconciliation, concurrent audit, and month-end close — without changing how your team works.
Most AI finance tools are copilots — they suggest, a human re-verifies, and the headcount never goes away. Finzo AI is built differently. Every compliance verdict is computed by deterministic code, not inferred by a model. Every invoice is audited at submission, not at month-end. Every MSME payment deadline is enforced automatically before it becomes a tax disallowance.
