Business owners, what is your biggest daily hassle/problem/pain-point?

Would be interested in hearing what your biggest daily problems/challenges/hassles/pain-points/sticky issues/you-name-it are?

Have you tried whipping up ad-hoc solutions yourselves?

What would it mean to you if your problem could be solved?

How often does the problem recur?

Are you using established tools but they are falling short of meeting your needs?

Ulterior motive: fishing for SaaS ideas :)
