A bakery could publish available breads, sizes and the ordering deadline. Customers would select a pickup window and receive an order summary. Quantities would be grouped by product for production planning, while a menu change would not silently alter an order the business had already accepted and committed to preparing for that customer.
An illustrative example to adapt to your business. It does not represent a completed project in this municipality.
Should sold-out products remain visible?
They can stay with a clear status and the next ordering opportunity, when known. This explains the range without allowing customers to select an item that cannot be supplied.
How can pickup reminders avoid becoming excessive?
Send a useful reminder with the address, selected window and order number. Avoid repeated follow-ups when the customer has already confirmed that they will collect the order.
