# Bird sale

> Record grown birds sold to a trader — the final lifting transaction.

A **Bird Sale** records grown birds leaving a batch for a trader. It's usually created automatically when you **convert** a [lifting intent](/lifting-gc/lifting-intents), but you can also create one directly.

| Field                            | Notes                                     |
| -------------------------------- | ----------------------------------------- |
| **Farmer / Batch**               | The batch the birds come from.            |
| **Date**                         | The sale date.                            |
| **To Customer / Trader**         | Who's buying. **Leave blank for godown.** |
| **Reference No.**, **DC Number** | Document references.                      |
| **Status**                       | Leave as **Completed**.                   |
| **Remark**                       | Optional.                                 |

**Line items:** **Product**, **Unit**, **No. of Birds**, **Total Weight**, **Rate** (per kg), and a calculated **Amount**.

## Auto vs manual weight

How the **Total Weight** is filled depends on where the sale came from:

| Source                              | Weight source | Behaviour                                                                                              |
| ----------------------------------- | ------------- | ------------------------------------------------------------------------------------------------------ |
| **Converted from a lifting intent** | **Auto**      | Total weight is derived from the sampled average — the field is **read-only** so it can't be mistyped. |
| **Created directly**                | **Manual**    | You enter the weight yourself.                                                                         |

A **Weight Source** badge (Auto/Manual) appears in the bird sale list so you can see which sales were backed by sampling.

## What a bird sale affects

* **Reduces** the batch's remaining bird count and records the **total weight sold** and **sale revenue**.
* Provides the **birds sold**, **weight**, and **sale rate** that the [GC calculation](/lifting-gc/gc-calculation) and the [Lifting](/reports/gc-reports) report rely on.
* If it was converted from an intent, it **closes** that intent.

<Tip>
  Because the GC payment depends on birds sold, total weight, and sale rate, always create the sale by **converting the lifting intent** — that keeps the weight accurate and the intent reconciled.
