The WooCommerce Delivery Slots plugin enables your customers to choose and reserve a delivery date and time for their order. As an admin, you are able to define available delivery days, as well as configure specific time slots. You can set a “lockout” number for each time slot; if you have a limited number of drivers each night, you can restrict specific time slots to a certain number of orders. On top of this, you can define days in the year where deliveries cannot be made; perfect for defining holidays and breaks.
