How do you all handle client reporting without losing half your week to it?

I run paid media and reporting is the part that quietly eats my week. Logging into every ad account, pulling numbers into a sheet, formatting it so the client actually gets it — it adds up fast.

The system I’ve landed on: I stopped rebuilding a report from scratch every time. One template, and I only update what changed since last week — spend, the two or three metrics the client actually reads, and a one-line “here’s what moved and why.”

Took it from a couple hours down to maybe 20 minutes.
Curious what everyone else does.
Living in Looker Studio?
Paying for one of the agency tools?
Still doing it by hand?

What actually saved you time vs. what just looked nice?
