Sorry, can I just add something?
You ask for a short turn. "Just" makes it sound small, so people happily let you in.
Examples
Sorry, can I just add something? The client wants it by Friday, not Monday.
Sorry, can I just add something before you book it? I've got the order number here.
In a conversation
A: ...so I think we should keep the smaller room for the client.
B: Sorry, can I just add something? There are eight of them, so it'll be a bit tight.
Common mistake
Not: I want to say something.
Say: Sorry, can I just add something?
"I want to..." sounds like a demand in English. "Can I just" asks for a small turn, and it's just as clear.
