# 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 in this tab you can edit or delete notes that have been previously added.
