Why your ad platforms disagree with Shopify
Meta, Google, and TikTok each claim credit for conversions using their own attribution windows and view-through rules. Add them up and you'll “sell” far more than Shopify actually recorded — because the same order gets counted two or three times.
These calculators give you a fast, transparent way to reconcile those numbers, find your true ROAS, and stop reallocating budget based on inflated platform reporting.
