Email an invoice to the customer with the PDF attached.

MYOB MCP tools: https://cotlet.dev/docs/mcp/myob.md

MCP tool: `myob_write → send_invoice`

Access: write. Confirm: waits for the user's OK before it runs.

Sends the invoice from the Share menu, Email invoice, to the address on the customer card unless you pass to. Attachments total up to 25MB. If the customer has no email address and you pass none, the call fails and sends nothing. The invoice then shows Emailed in its activity history. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `invoice_number` | string | yes | Invoice number from list_invoices or create_invoice. |
| `to` | array | no | Email addresses. Default: the address on the customer card. |
| `cc` | array | no | Email addresses to copy. |
| `subject` | string | no | Subject line. Default: the MYOB email default. |
| `message` | string | no | Message text. Default: the MYOB email default. |
| `email_me_a_copy` | boolean | no | Send yourself a copy the customer cannot see. Default: false. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
