Is ROAS the same as ROI?

No. ROAS compares revenue to ad spend. ROI compares profit to total investment.

Why does attributed revenue differ between platforms?

Ad platforms use different attribution windows and models, so their reported revenue rarely matches your store's own totals.

Understand it

A 4x ROAS means £4 of tracked revenue per £1 of ad spend. If your gross margin is 25%, 4x ROAS is exactly break-even before overheads.

Break-even ROAS is 1 divided by your contribution margin. Knowing that number turns campaign decisions from guesswork into arithmetic.
