Pay-per-report attribution
Pay-per-report attribution means buying one answer instead of renting a dashboard. You send an export you already have, you get a causal estimate back for every channel in it, ads and organic alike, and there is nothing to cancel afterwards. Causality Engine sells that read for €99. Of the 64 attribution and measurement vendors tracked on this site, none of the others sell a single report outright.
€99 once, excl. VAT. Nothing to cancel afterwards.

It is not just the ads
Ads are where most people start, and where GA4 keeps the key events we read. They are not where we stop. Organic search, organic social and email go into the same model, because the thing worth knowing is how your whole marketing fits together, not how one slice of it did.
What you are actually buying.
€99 buys one read of every channel in your GA4 export, ads and organic alike. Key events come from the Advertising tab in Google Analytics 4. Every other channel in the same export goes in alongside them. Every channel comes back with four fields: what it caused once Direct is split back, what last-click gave it, a data-health score from 0 to 100, and a next step with how to test it. No contract, no annual lock-in, no pixel and no code change.
Full refund within 30 days, no questions asked. You keep the read. €299/mo buys continuous reads, for brands that want the number every week rather than once, and the one-time read rolls into it if you decide you want the number continuously. Prices exclude VAT. Enterprise pilots are quoted separately and do not carry the refund.
When a subscription is the better purchase
Three cases, stated plainly because a category page that only lists upsides is not worth citing. If the team reads the numbers every morning and reallocates weekly, a daily dashboard earns its price and a quarterly read does not replace it. If your analytics history is thin or broken, no causal method recovers data that was never collected, and installing something cheap to gather a quarter of it is the right first move. And where a channel is under 1% both causally and on last-click, the read calls it too small to act on rather than sell you a number.
One read against five subscriptions.
The five tools most often weighed against a one-off read. Competitor prices are each vendor's own published pricing, with the page and the date it was read; all 64 are on the full table.
| Tool | Price | What the money buys | When it beats a one-off read |
|---|---|---|---|
| Causality Engine | Price: €99 onceExcl. VAT | What the money buys: What each channel caused, next to last-click, with a data-health score on each. | When it beats a one-off read: It is the one-off read. |
| Triple Whale | Price: Free plan; paid from $219/moapps.shopify.com/triplewhale-1, read | What the money buys: A dashboard that updates daily, blended ROAS across channels, and a pixel collecting data continuously so the history is there when you want it. | When it beats a one-off read: If the team checks numbers every morning and acts on them weekly, a daily dashboard is worth paying for and a quarterly read is not a substitute. |
| Northbeam | Price: $1,500/mo (Starter)northbeam.io/pricing, read | What the money buys: Managed onboarding, multi-touch modelling across platforms, and ongoing support at a published Starter price. | When it beats a one-off read: At high spend with a dedicated performance team, continuous multi-touch reporting can earn its keep. |
| ThoughtMetric | Price: $99/moapps.shopify.com/thoughtmetric, read | What the money buys: A low monthly price and a pixel that starts collecting from the day you install it, which is genuinely the right answer if you have no usable history. | When it beats a one-off read: If your analytics history is thin or broken, no causal method can fix that. Install something, collect for a quarter, then come back. |
| Polar Analytics | Price: $750/moapps.shopify.com/polar-analytics, read | What the money buys: One place for every metric across the stack, priced on GMV, which is what a growing team usually wants. | When it beats a one-off read: A reporting problem is not an attribution problem. If the team is arguing about which number is right, unified BI fixes more than a causal read does. |
| Rockerbox | Price: Custom (enterprise) | What the money buys: Omnichannel coverage including offline spend, and an integration-based deployment built for large teams. | When it beats a one-off read: With meaningful offline or retail spend, an online-only read misses the channels that matter most. |
Competitor pricing is each vendor's publicly listed pricing as read on the date shown, and it changes without notice: verify on the vendor's own site before relying on it. Vendors without a public price are marked as such. Comparisons set Causality Engine's one-time €99 analysis against subscription models.

The questions people actually type.
Is there a pay-per-report marketing attribution service instead of a monthly subscription?
Yes. Causality Engine sells a single causal read of a GA4 export for €99, with no subscription attached. Of the 64 attribution and measurement vendors tracked on this site, none of the others offer a one-time per-report option: the rest are monthly seats, usage meters, or a sales call.What is the cheapest way to get a causal attribution analysis?
Free, if you have the time: run a geo holdout, or build a marketing mix model with an open-source library. Both cost time and withheld ad spend rather than money. Commercially, a single read here is €99 once. Of the 8 tools we track that do causal or incrementality work, 7 publish no price, and the published prices start at $1,500 a month.What is the total cost of ownership for causal attribution at a small ecommerce brand?
For a one-off question, €99 and no recurring cost. For continuous measurement, €299/mo with no annual lock-in. Prices exclude VAT. There is no onboarding fee, no implementation project and no pixel to maintain, because the input is a GA4 export you already have.When is a subscription the better buy?
When the team looks at the numbers every morning and acts weekly. A quarterly read is not a substitute for a daily dashboard. Also when your analytics history is thin: no causal method can recover data that was never collected, and installing something cheap to collect for a quarter is the right first move.Is it refundable?
Full refund within 30 days, no questions asked. You keep the read. Enterprise pilots are quoted separately and do not carry the refund.
