# Managing Sale State

**`close_sale<CURRENCY>(...)`** and **`reopen_sale<CURRENCY>(...)`**\
**Purpose**: Control the sale state. Closing a sale prevents further purchases; reopening it allows buying again.

**Close Sale Process**:

1. Verify the caller is the sale creator.
2. Ensure the sale is currently active.
3. Set `is_active = false`.
4. Emit a status change event.

**Reopen Sale Process**:

1. Verify the caller is the sale creator.
2. Ensure the sale is inactive.
3. Check that there are still NFTs available in the sale.
4. Set `is_active = true` and emit the appropriate event.

**Use Cases**:

* Temporarily pause sales for maintenance or to adjust prices and then reopen later.
* End the sale permanently once all desired NFTs are sold or no longer for sale.

By leveraging these functions and entry points, the SALE module offers a straightforward, flexible mechanism for launching NFT sales, adjusting inventory, and handling payment flows. Creators gain full control over their selling process, while buyers enjoy a simple, direct purchasing experience.
