cap off the meeting with a statement/final thought/proposal
To ‘cap off’ something means to conclude or finish something. You might ‘cap off’ a conference with a final address. You could ‘cap off’ a night out with something nice to drink. ‘To cap it all off’ can be used to preclude something final in a list, for example, “I had the worst day in work, my computer crashed, I lost all my work, I had to stay late and to cap it all off when I got to my car the battery was dead.” This is a phrase you will often hear in business contexts at the end of meetings and presentations..
