Your ad data tells one story. Your Shopify tells another.

You can trust them within their own silo. Google's ROAS is accurate for what Google can measure. Meta's is accurate for what Meta can measure. The problem is both platforms report against a revenue figure that includes shipping and taxes — not your actual product revenue — and they each claim credit for the same sale.

We take the ROAS your platforms report, pull your actual Shopify net sales independently, and calculate the gap. That gap — the overclaim ratio — is what's distorting your budget decisions. Across accounts we audit, it typically sits between 1.8x and 4.3x. Most business owners are genuinely surprised by how large it is.

No — and we won't pretend otherwise. Perfect attribution is impossible. After iOS 14 removed cookie tracking, no tool can perfectly trace every purchase back to the ad that caused it. Anyone claiming otherwise is selling you false precision.

What we do is surface the discrepancy between what your platforms claim and what Shopify actually recorded — and tell you exactly how large that gap is per platform. That's not a perfect ROAS figure. It's an honest measurement of how far off your current numbers are, which is far more useful than a made-up precise number.

Most audit tools look inside one platform and report what that platform thinks is wrong. We look across Google Ads, Meta, and Shopify simultaneously — and use Shopify revenue as the final arbiter of what's actually working.

Every finding is specific to your account: named campaigns, named keywords, named ads, dollar figures calculated from your actual spend data. Not industry benchmarks. Not AI guesses. Things you can verify yourself in 30 seconds by opening your ad account.

Good catch — this is exactly what most tools ignore. We use Shopify Online Store channel net sales only, which excludes wholesale, POS, and draft orders. Refunds are factored in automatically.

This is also one reason the overclaim gap tends to be larger than people expect. Platforms report their claimed revenue against your gross order total — which includes shipping and taxes. Shopify net sales excludes both. So the platforms are comparing their inflated figure against a higher starting number, which makes the true gap wider once you normalise for it.

Possibly — but agencies are typically platform-native. They live inside Google or Meta and report using those platform numbers. They're not structurally incentivised to surface attribution inflation because it would undermine their own reported results. This isn't a criticism — it's how the industry works.

An independent tool reconciling against Shopify gives you a check on your agency's numbers that they genuinely cannot provide themselves. Several agencies use getquant to give their clients a more honest picture — and find it strengthens rather than undermines the relationship.

2 minutes to connect. 30 seconds to run. Connect Google Ads, Meta, and Shopify via OAuth — the same secure login flow you'd use for any app integration. No CSV exports, no spreadsheets, no setup calls required.

The audit report is written in plain language with a dollar figure attached to every finding. You don't need to understand attribution modelling to act on it. Most people find their first actionable finding within 5 minutes of connecting their accounts.

If you're spending $10K/month or more, the audit typically surfaces 10–25% in recoverable waste. At $10K that's $1,000–$2,500 per month — enough to justify the cost many times over.

The free audit tells you the exact waste figure for your account before you pay anything. If the findings don't justify the cost, don't upgrade. We'd rather you walk away with a useful free report than pay for something that doesn't move the needle for your account.
