Creating a field that automatically increments itself when the file is
opened is not difficult.
The problem is that if people start making copies of the file, you will end
up with multiple versions having the same serial number, which I guess
should be unique.
One possible solution is to use random numbers instead of consecutive ones.

Which part don't you understand?
There are many ways and more information will be needed. You can create a form and connect to database control the serial numbering and keep it in sequentail order, but that is an advanced technique.
If only one person will be creating the serial numbered form then you can easily add from field that increment that time the form is opened, but the user must save the form to keep the serial number updated.
If you do not not sequential control of the serial number then you can apply random numbers or serial number created from the JS data time object.
