ChatGPT + accounting MCP
ChatGPT accounting agent for Swiss SMEs and fiduciaries
Give ChatGPT a governed accounting surface instead of raw exports, with Numezis controlling documents, VAT context and approval-ready actions.
ChatGPT / Numezis
ChatGPT accounting agent
ChatGPT is strongest in accounting when it can reason over structured business context without becoming the system of record. Numezis MCP lets ChatGPT inspect accounting documents, VAT-relevant records, journals, approvals and evidence while Numezis remains the governed source of truth. Accountants and fiduciaries can use the agent to prepare work faster while keeping validation, permissions and audit trail intact.

- Audit metadata remains attached to accounting decisions.
- The same control model works for SMEs and fiduciary users.
