What’s the hardest part of managing freelance clients right now?

I’m building Freelancer Client OS, a Notion CRM for freelancers, and I wanted to ask the community what part of client management is most frustrating for you.

Is it keeping track of leads, following up with clients, staying organized across projects, or managing payments and deadlines?

I’d love to hear what’s most annoying so I can keep improving the system and focus on what actually helps real freelance workflows.
