Stop guessing why ROAS dropped. Sentrum surfaces what changed — creative fatigue, audience saturation, CPM spikes — before your numbers crater.
Built for e-commerce teams managing real spend on Meta. Get the diagnostic layer Ads Manager is missing.
These are the problems e-commerce & d2c teams face every week.
"I woke up and ROAS tanked and I have no idea why."
Spending $150K/mo. ROAS went from 4.2x to 2.1x overnight. Ads Manager shows nothing obvious.
"Our best creative just stopped working after two weeks."
Creative fatigue is invisible until it's too late. By the time CPMs spike, your winning ads are already dead.
"We scaled spend 30% and efficiency fell off a cliff."
Audience saturation hits different at scale. You need to know when you're hitting a ceiling, not after you've crashed through it.
"Meta says 200 purchases, Shopify says 140. Who's right?"
Attribution discrepancies make it impossible to know which campaigns are actually driving revenue.

Common questions about using Sentrum for e-commerce & d2c.
Sentrum pulls revenue and spend data from your Meta ad account daily and calculates ROAS at every level — account, campaign, ad set, and ad. When ROAS changes, Sentrum automatically decomposes the shift into its root causes: CPM changes, CTR shifts, conversion rate movement, and average order value changes. You see exactly which lever moved and why.
Yes. Sentrum monitors CTR trends, frequency, and efficiency curves for every active ad. When an ad's click-through rate begins declining — typically 3–5 days before it shows up as a CPM spike or ROAS drop — Sentrum flags it. This gives you time to prepare new creative before performance craters.
Sentrum currently pulls data directly from Meta's API. While we don't have a native Shopify integration yet, our diagnostics use Meta's conversion data to analyze ROAS, purchase volume, and cost per acquisition. A Shopify integration for reconciling attribution discrepancies is on our roadmap.
Ads Manager shows you what happened — Sentrum tells you why. When your CPA doubles overnight, Ads Manager shows the number. Sentrum decomposes that change into CPM shifts, CTR decline, conversion rate drops, and mix effects (like budget shifting toward less efficient campaigns). It's the diagnostic layer that Ads Manager is missing.
