Try asking

  • “Which invoices are overdue right now?”

    The AI lists invoices with status overdue, with customer, due date and balance due.

  • “Invoice Acme Ltd for 12 hours of design work at 90 EUR.”

    It finds the customer and creates the invoice as a draft with one line item. It is only emailed if you ask it to send.

  • “Acme paid invoice INV-000231 by bank transfer today.”

    It records the payment against that invoice with date, amount and payment mode. No money is charged; the invoice is marked as paid.

What your AI can do

Invoices and payments

List and filter invoices by status or customer, create and update invoices, record payments and email invoices.

Estimates and customers

Create and email estimates, mark them accepted, and search, create and update customers with payment terms.

Items and expenses

Look up and edit products and services, record expenses, list recurring invoice profiles and email account statements.

  • “Send an estimate to Nordic Foods for the spring campaign.”

    It creates the estimate with line items, expiry date and terms, and emails it to the customer if you confirm.

  • “Email Acme a statement for the last quarter.”

    It emails the customer's account statement for the date range you give to the addresses you choose.

  • “How much did we spend on travel this month?”

    It lists expenses filtered by date and account, with amounts and reference numbers.

Questions

What can the AI do in Zoho Invoice?

The AI can read and search invoices, payments, estimates, customers, items, expenses, recurring invoice profiles and organizations. It can create and update customers, items and invoices, create estimates and expenses, record payments, mark invoices as sent and estimates as accepted, and email invoices, estimates and statements. It can also void or delete an invoice if you switch those tools on.

Does the AI see my Zoho Invoice credentials?

No. Your Zoho Invoice credentials 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, estimate or statement reaches your customer, and voiding or deleting an invoice changes what is owed. All of these can require your approval before they run. 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 Invoice connects with OAuth, and this OAuth connection needs the PipMCP Pro plan. 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 Invoice account.

Why do I need the Organization ID and domain ending?

Zoho runs separate data centers, so PipMCP needs your domain ending (for example com or eu) to reach the right one. One Zoho login can have several Zoho Invoice organizations, and the Organization ID tells PipMCP which one the AI works in.
