For online stores

Know every sale still reaches Google and Meta.

Your ad accounts learn from the purchases your site reports. We watch every one on real visits and email you the day it stops, or starts arriving worth nothing.

Sounds familiar?

  • “Ad spend went up. Reported sales went down.”

  • “We moved to a new theme and conversions quietly stopped.”

  • “The pixel fires, but Meta says the sale was $0.”

Hear about it the day it breaks, not at month end.

A theme update renames a button. A new app swaps your checkout. The tags still fire, so every report looks normal. We compare each purchase with the ones before it and tell you what changed.

  • One email when it breaks and one when it recovers. Never reminders.
  • A plain summary to copy straight to your developer.

Every purchase, and every tag it reached.

See which tags fired from each event and where each one sent it: GA4, Google Ads, Meta and the rest. A test tag or an old agency's pixel shows up the moment it fires.

Your sales, live.

Mark purchase, add to cart and sign-up as key events, and we watch them closest.

Purchase stopped arriving

TagSentry · 09:14 · to you

We haven't seen a purchase since 09:12. Your other events are still arriving, so a change to the checkout is the likely cause.

What a busy store pays.

Each site is priced by its own use, and moves up a level only as it grows. You get one email when it does.

Store owners ask us.

We're on Shopify. Does it see our checkout?

Not yet. Shopify's checkout pages don't run your theme's code, so our line doesn't load there. On your storefront it sees every event and the pixels in your theme, like product views, add to cart and sign-ups. On other platforms it watches the purchase itself.

What exactly do we get emailed about?

On every plan, the day an event like purchase stops arriving, or a new tracker appears. On paid plans, also the day a key event arrives empty or drops below its usual volume. One email when it breaks, one when it's fixed.

Will a cookie banner cost us sales data?

Less than most. Visitors in opt-out places like most of the US keep being counted until they say no. In ask-first places Google still gets cookieless signals it uses to fill the gaps.

Do you see our customers' order details?

No. We keep the shape of each payload, never its values: that value was a number and currency three letters, not what they were. Nothing that identifies a person leaves the browser.

Not quite you?
