# Note

Notes are crucial for sales, the Notes tab on the product detail page allows you to type any text you want to add to the product. For example, when a product category or unit does not match, you can add a note to provide information that the entered category or unit does not match, or perhaps when the product price rises, you can add a note to provide information about price changes.

The notes that have been successfully added will be entered on the **Timeline** tab and on this tab you can edit or delete notes that have been previously added.
