The AI prepares the work; a person approves it before it posts. Zeno connects the AI you already use to QuickBooks, for one company or for a firm's clients. QuickBooks stays the ledger. Zeno holds the bank and card queue, the document inbox, the rules and facts each company has taught it, the plans, and the record behind every posting. ## How a write happens Every write Zeno makes follows the same steps, whether the company is on QuickBooks Online or QuickBooks Desktop: 1. The AI prepares a plan against the live ledger. 2. Zeno checks names, accounts, duplicates, and the company's rules. 3. A person reads the plan and approves it, or holds the lines they disagree with. 4. Zeno posts only the approved entries. 5. The run stays on record, with a way to reverse it. How a write happens ## Where it runs Use the firm workspace with QuickBooks Online. For a company file that stays on a Windows workstation, run Zeno locally with QuickBooks Desktop. Both follow the steps above. Two places Zeno runs One queue of bank and card activity, a document inbox, expense claims, review, company memory, and hosted QuickBooks Online connections, across every client. The same plan, approve, post, and record steps on the Windows workstation that holds the company file. ## Common starting points Connect the AI client you use, then add the first QuickBooks Online company. What happens at each step, and why Zeno may refuse to apply a plan. Claude, ChatGPT, Claude Code, or Codex on your firm's books over MCP. Statements and live connections on one queue, coded by rules and the assistant, matched against what the ledger already holds. Company cards as a lane of the queue: receipts, a cardholder's submission, a reviewer's approval before anything posts. Follow the Desktop workflow from proposal through approval, posting, and reversal. Every tool a connected AI client can call against QuickBooks Online, and what each one refuses to do. Check sign-in, client authorization, ledger sync, plans, and bank connections. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
