This is interesting and it's key of good communication between you, and the clients. So here is what I found out in the internet.
"How to Refocus a Meeting After Someone Interrupts"
https://hbr.org/2015/04/how-to-refocus-a-meeting-after-someone-interruptsPrinciples to Remember
Do:
»Prepare an agenda ahead of time and ask colleagues for their input
»Listen to what the interrupter is saying and validate his points
»Redirect the conversation by restating the purpose of the meeting
For example you can say before the meeting starts that you can pause for them if you had to repeat what you've been said earlier and make it clearer, let them know that it's okay for you to be interrupted or not otherwise you can say you can only answer the other questions after the presentation.
Don't:
»Get upset and emotional about the interruption - stay calm and collected
»Be in a hurry to brush off an interruption - sometimes it's worth probing further to gather more information
»Scold your employee after the meeting - instead pose questions and listen
