How do you stay accurate/detail-oriented when juggling multiple deadlines?

I work in tax/professional services and lately I’ve been catching myself making small inattention errors (typos, minor inconsistencies) when I have too many files going at once. I know what to do (slow down, use a checklist) but I struggle to actually apply it when things feel urgent.

For people in similar high-volume, detail-heavy roles: what’s actually worked for you to cut down on these kinds of mistakes? Habits, tools, mindset shifts — genuinely curious what’s helped others.
