How do you track Facebook ads when you're running other platforms too?

Running campaigns on Facebook, Google Ads, and TikTok. My issue is I can't see the full picture of what's working because all the data is split across different dashboards.

I'll think a campaign is doing great on Facebook, then realize Google is bringing way better ROAS with the same budget. Or I'll want to see which creative performs best overall, but I have to manually compare numbers from three different platforms.

Right now I'm exporting reports and putting everything in a spreadsheet, but it's tedious and by the time I'm done the data is already outdated. Plus I'm never 100% sure I'm comparing things correctly since each platform calculates metrics differently.

Is there a better way to see all your ad performance in one place? How are you guys handling cross-platform tracking and comparison?
