# POST /api/v1/orders/from-estimate/{estimate_id}

> Create order from estimate

- **Tag:** orders
- **Operation ID:** `create_order_from_estimate_api_v1_orders_from_estimate__estimate_id__post`

## Description

Convert a draft or accepted estimate into a new draft order. The customer, currency, description, and line items carry over (every line billed as a one-time `flat` fee); an optional `project_id` in the body attaches the order to a project. The estimate is marked converted and linked to the order — converting it a second time (or converting it to an invoice afterwards) is rejected.

## Authentication

Required header: `x-business-id: <business uuid>`.

## Parameters

- `estimate_id` (path, string, required)
