Create an AR invoice for a customer with one or more lines. On Hold by default.

Acumatica API: https://cotlet.dev/docs/api/acumatica.md

`POST https://cotlet.dev/api/v1/acumatica/customers/{customer_id}/ar-invoices`

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

Creates an invoice in Invoices and Memos for one customer. With hold set to true, the default, the invoice is saved On Hold; with false it is saved Balanced and can be released. The total is the sum of quantity times unit price over the lines. Taxes follow your Acumatica setup. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `customer_id` | string | yes | Customer ID as shown in Acumatica, from list_customers. |
| `date` | date | yes | Document date. |
| `hold` | boolean | no | true saves the document On Hold so you can review it. false saves it as Balanced, ready to release. Default: true. |
| `lines` | array | yes | Objects with description (string), quantity (number) and unit_price (number). |
