Send or resend an invoice to the customer by email or text with a message.

Housecall Pro MCP tools: https://cotlet.dev/docs/mcp/housecall-pro.md

MCP tool: `housecall_pro_write → send_invoice`

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

Sends an invoice by email, text or both, with a custom subject and message, to the customer or to extra email addresses. Text needs online payments enabled on the invoice and a number in the Mobile field. Resending an invoice restarts the automatic reminder cadence. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `invoice_id` | string | yes | Invoice ID from list_invoices or get_job. |
| `channels` | string[] | no | email, text or both. Default: ['email']. Text needs texting enabled on the account and a number in the customer's Mobile field. |
| `to` | string[] | no | Extra email addresses. Default: the customer's email. |
| `subject` | string | no | Email subject. |
| `message` | string | no | Message to the customer. |

## 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.
