Im having a issue where I have fulfilled an order and it was delivered to customer door step via drop off.
There’s no tracking number and have proof of the package been dropped off via picture of the house and also order confirmation # and details.
How could I fulfill this order correctly where the customer will have details
Hey AVDTech,
This help doc explains how to add tracking numbers to orders when you’re fulfilling them: https://help.shopify.com/en/manual/orders/status-tracking/add-tracking-numbers
There are also a number of ‘order tracking’ apps on the Shopify app store, which will allow you to have a page on your site where customers can enter their order number and email to view tracking progress: https://apps.shopify.com/search?q=order%20tracking
The most popular one is the AfterShip app: https://apps.shopify.com/aftership
Hope this helps! 
Cheers,
Stephen
