If you have a product that is deleted in Xero you need to manually delete the product in Onsight for it not to display in the app. This does not happen automatically. This is because the Xero API does not allow the product status information to be pulled out of Xero. To delete a product in Onsight, follow the following steps:

• Log in to the Onsight admin console at https://web.onsightapp.com/.
• Click on ‘Catalogue’ in the left-hand side menu.
• Click on the ‘Manage Products’ menu item.
• Click in the checkbox to the left of the product you want to delete. A checkmark should appear.
• Click on the ‘Delete’ button that appears at the top of the products list.
• Click on the ‘Yes’ button in the popup menu.
