Questions

Why is ROAS calculated from totals?

Averaging daily ROAS over-weights quiet days. Superlytix divides total conversion value by total cost for whatever you're looking at, the same way the ad platform does.

Can I add other ad platforms?

Yes. Upload their exports too and ask for cost by platform; columns with different names are matched in plain words.

What if conversions have decimals?

That's normal with data-driven attribution. They're treated as counts, not money.
