Hi,
HikaShop business have "order custom fields". It allows you to create new options, new data for the order during the checkout.
You can see some in our demo website :
* Additional information you would like us to know (text)
* Would you like you package delivered on a specific date ? (yes/no)
* Delivery date (date)
By selecting "yes" on the second, the last one (the delivery date) will be displayed.
This custom field ask for the customer to select a future date. This information will be stored in the order and you will be able to see it.
