Hey Marcus, so about the deadline - I think we might need more time? The client keeps changing stuff and honestly it's getting kinda hard to keep up. Can we maybe push it back a week or so? Lmk what you think.
Hi Marcus, I wanted to discuss the project timeline. Given the recent scope changes from the client, I believe an extension would help us deliver higher-quality work. Would it be possible to push the deadline back by one week? I'm happy to walk through the specifics whenever works for you.
