Theoretical case: client suggests some non-optimal solution. How to offer another, better solution politely with indirect question? Is it ok to say "Don't you think doing it this way would be more efficient?" or using "Don't you think" implies that client might be incompetent in a way that he might have forgotten to consider the solution I offer?
P.S. I forgot to add – it's a written dialog, via Skype or email.

I would start with the word 'consider' as in:
...followed by supporting argument(s).
I would certainly avoid using you/me/I at all and personal opinion. Instead, listing the plus points should serve better.
