Connect Claude & ChatGPT to Zoho Books
Ask your AI which invoices are overdue, what a customer owes, or to draft an invoice or estimate in Zoho Books. It can record customer payments, create credit notes, and log vendor bills and expenses against the right accounts. It can also turn accepted estimates into invoices and email invoices and estimates to your customers.
Free plan, no credit card. Takes about a minute.
Try asking
“Which invoices are overdue, and who owes the most?”
The AI lists invoices with status overdue, with customer, due date and balance due.
“Create a draft invoice for Acme Ltd: 8 hours of design at 120 per hour, due in 14 days.”
It finds the customer and creates a draft invoice with one line item, date and due date. Nothing is emailed.
“Acme paid 960 by bank transfer today. Apply it to invoice INV-000231.”
It records the customer payment with date, amount and payment mode and applies it to the invoice, which lowers the balance due.

Questions
What can the AI do in Zoho Books?
The AI can read invoices, estimates, credit notes, customer payments, bills, expenses, contacts, items and the chart of accounts. It can create and update invoices and contacts, create estimates, credit notes, bills, expenses and items, record customer payments, convert estimates to invoices and email invoices and estimates, if you switch those tools on.
Does the AI see my Zoho Books credentials?
No. Your Client ID, Client secret and the access PipMCP gets from your Zoho login are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.
Can I control what the AI is allowed to do?
Yes. You choose which tools are switched on, so you can start read-only. Emailing an invoice or estimate goes out right away and cannot be recalled, and recording a payment changes what the customer owes. These actions can require your approval before they run, and every tool call is logged.
Does it work with ChatGPT?
Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.
What does it cost?
Zoho Books connects with OAuth, and OAuth connections need the PipMCP Pro plan or above. PipMCP also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own Zoho Books account.
Why do I need to create a client in the Zoho API console?
Zoho Books uses OAuth, so PipMCP needs a Client ID and Client secret from a server-based application that you create in your own Zoho account. You set its redirect URI to https://pipmcp.com/oauth/callback, paste the values into PipMCP and log in with Zoho to approve access. Pick the domain ending that matches your Zoho data center, for example eu or com.
