Shopify says one thing.
Meta says another.
Xero says the truth.
Chartcastr joins Shopify, Meta Ads, Klaviyo and Xero into one daily pulse, so you stop trusting platform-reported ROAS and start running the store on actual contribution margin.
Strong revenue day, but blended margin dropped 6pts. Supplier price hike on the hero tee is eating most of the lift. Meta’s reported 4.2x ROAS is closer to 1.4x once COGS and returns are in. Consider repricing before the next ad push.
Meta says you’re winning.
Your bank account disagrees.
Every ad platform reports the ROAS that flatters it. Stripped of returns, COGS, shipping and payment fees, that 4.2x is often closer to 1.1x. The number that actually matters lives across three systems, and no one’s reconciling it.
One ROAS, three truths
Chartcastr shows you platform-reported, net-of-returns, and true contribution margin in the same Slack message.
Your store doesn’t stop.
Your team does.
Most ecomm catastrophes happen at the worst time to notice them: Saturday night ad bleeds, Sunday stockouts, refund spikes on a public holiday. Chartcastr watches the numbers when you can’t, and pings the right channel only when something actually moved.
The overnight ad bleed
Boost campaign tanks from 3.1x to 0.4x ROAS in six hours. Chartcastr pings #marketing at 8:02 am Sunday with the spend curve and the SKU mix. You pause it before brunch. Without us, you find out Monday — $4,800 lighter.
The silent stockout
Hero SKU velocity hit 18 units/day on the back of a Klaviyo flow. At 11 days cover and rising sell-through, Chartcastr flags it before your ops lead has to refresh Shopify for the fifth time. Re-order goes in same morning.
The quiet margin compression
Net new orders look fine. But your blended margin dropped 4pts week over week — supplier hike on one ingredient is eating the gain. The weekly pulse pulls it from Xero before it shows up in next month’s P&L.
