We can go all Treitel if we want but this should cover what we are looking at:

After an order is placed

You must:

    confirm the contract as soon as possible and no later than when goods are delivered, a service starts or digital content is downloaded (for example, an email must be sent when content is downloaded even if it does not arrive at the same time)
    provide a copy of the contract on paper, by email or another format the customer can save for future reference
    deliver the goods within 30 days, unless you’ve agreed otherwise with the customer
