Agency owners, what's your most annoying operational problem

Hey, I'm not an agency owner, just a regular SEO.

Just doing a research.

Not asking about getting leads or ranking client sites. I’m more curious about the internal side of running SEO work.

Things like:

• tracking what was actually done for each client
• keeping client work organized across tasks, docs, sheets, Slack, etc.
• reporting work clearly at the end of the month
• knowing who changed what and when
• making sure important SEO changes stay live
• managing multiple clients without everything becoming scattered

For people running SEO agencies or managing SEO teams, what part of the workflow is still messy even though you already have tools for project management, reporting, and SEO audits?
