Online consultation: Should notes be ready right after the consultation?

We are building an online consultation app where in there's a consultant and a customer who can do a video conference over the phone / desktop computer.

On the consultant's side, we are planning to allow them to type notes while they are talking to the customer. However, this note-taking may be quite a lot and there's a time limit to the conference (say, 15 mins.)

Once the 15 mins. is over, the conference would end (the customer will see an "Appointment has ended!" page).

Now, it would be great that once the consultation is over, the customer can immediately read a summary of the consultation. However, there may be instances that this is not possible, since the consultant may need more time to write more notes.

Is this a good way to approach this?

  1. For those consultants who can type brief summary, then as per normal, the customer will receive the notes right after the conference ends. For those consultants who need more time, the customer will need to be further notified (via Push notification & email), that the notes are ready to view (which may take 5-10 minutes after the consultation).

OR

  1. Just make it notification-based. Meaning, every time a consultation ends, the customer would need to be notified when their notes are ready for viewing. That is so that they would have a consistent expectation after the call ends.
