# How to Choose a Pick Rule

> Understand the different pick rules available -- FIFO, LIFO, Sell By Date, and Best Before Date -- and when to use each one.

## Understanding Pick Rules

Pick rules determine how stock is prioritised during the picking process. Choose the rule that best matches your business needs for efficient and accurate stock dispatch.

### Available Pick Rules

| Pick Rule                      | How It Works                                        | Best For                                                     |
| ------------------------------ | --------------------------------------------------- | ------------------------------------------------------------ |
| **FIFO** (First In, First Out) | Picks the oldest stock first                        | Perishable goods; ensuring older stock is dispatched first   |
| **LIFO** (Last In, First Out)  | Picks the most recent stock first                   | Products where newest stock should be prioritised            |
| **Sell By Date**               | Picks items closest to their sell-by date first     | Products with expiration dates                               |
| **Best Before Date**           | Picks items closest to their best-before date first | Products where freshness matters, even without strict expiry |

<Tip>Pick rules are applied at the account level, meaning you can customise them for different accounts. You can change the pick rule at any time through the account settings.</Tip>
