# Your Zoho Invoice. Paid on time.

Source: https://corespeed.io/integrations/zoho-invoice

Connect Zoho Invoice to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads your invoices, recurring invoices, estimates and payments received, and tells you which customers need a reminder. It uses your own Zoho login. Sending an invoice, a payment reminder or an estimate is a separate call that approvals can hold for a person.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Zoho Invoice after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## Know who is late. Remind only them

Let your agent read overdue invoices and recent payments in Zoho Invoice, so a reminder goes only to the customers who have not paid.

You ask your agent: "In Zoho Invoice, list the overdue invoices and the payments received this week. Tell me who still needs a reminder. Do not send anything."

It calls CoreSpeed:

- `zoho-invoice__list_invoices`: ok, 476 ms
- `zoho-invoice__list_customer_payments`: ok, 389 ms

It reads from: Zoho Invoice.

### Reminders: Two customers to remind.

Three invoices were overdue. Pell Street Gym paid this week, so two customers still need a reminder.

## Keep your agent. Bring your work

One CoreSpeed account, across compatible agents.

1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in.
2. **Connect Zoho Invoice**: Authorize the account and the content you need.
3. **Start with one task**: Ask for a summary, a brief, or a draft. Review the answer.

## Questions

### Can my agent send invoices and reminders?

Yes, when you ask. Emailing an invoice, an estimate or a payment reminder is a separate tool call that approvals can hold. How approvals work: https://corespeed.io/docs/approvals

### Can it change recurring invoices?

No. Your agent can list recurring invoice profiles and read each one's schedule, but CoreSpeed's tools do not change them.

### How is this different from the Zoho Books page?

Zoho Invoice covers invoicing only. Zoho Books adds bills and orders. Each has its own connection.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
