Create an invoice from an estimate.

Method CRM MCP tools: https://cotlet.dev/docs/mcp/method-crm.md

MCP tool: `method_crm_write → convert_estimate_to_invoice`

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

Does what Create > Create Invoice does and saves the invoice. A deposit already received appears as a line item with your Deposit Item. The customer is not contacted; send_invoice does that. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `estimate_id` | string | yes | Estimate ID. |
| `wait_for_sync_approval` | boolean | no | Ticks "Wait for approval before syncing" so QuickBooks stays untouched until you untick it in Method. Default true. |
