The cost of waiting for a data hire: Waiting until you can afford an analyst has a price, and it is paid every month in allocation nobody can check. Three costs, with the arithmetic.

How much Meta over-reports ROAS after iOS privacy changes
Deferring measurement until you can hire an analyst has a price, and it is paid monthly in allocation nobody can check. Three costs, all estimable today.
The three
| Cost | How to size it |
|---|---|
| Misallocation while you wait | Monthly ad spend times a plausible correction from your own claim ratio |
| Lost measurement windows | Retention expiring on periods you will later want to read |
| Habits set on the wrong number | Thresholds calibrated against reported ROAS, hard to reset later |
The first is the obvious one
Take the sum of what your ad platforms claim for last month, divide by what your store actually took, and look at how far above one it sits. That excess is the overlap in your reporting, and budget is currently being allocated as though it were not there.
Multiply your monthly spend by even a conservative fraction of that distortion and compare it against what a read costs. The comparison is rarely close. The method is in the claim ratio.
The second is the quiet one
Analytics retention settings can be short, and detail that expires is not recoverable at any price. Waiting a year to start measuring can mean the year you wanted to look back on is no longer readable. Checking the setting takes two minutes and is worth doing today regardless of what you decide about tooling. The retention trap covers it.
The third is the sticky one
If your team spends two years setting scaling and cutting thresholds against reported ROAS, those thresholds encode the overlap. Switching later means every channel appears to get worse overnight and every threshold has to be renegotiated, which is a political cost on top of an analytical one. The reset process is in replacing multi-touch attribution in four steps.
What a hire genuinely adds
Real things: warehouse modelling, experiment design at depth, and building what you cannot buy. Those are worth hiring for when the scale justifies it.
What a hire does not do is make a per-channel causal read possible, because that does not require one. A Google Analytics export and a read gets you an estimate with its confidence interval, coverage and design label per channel, at €99 once, refundable if it does not move a budget decision, with nothing installed on your store.
The honest counter-argument
If your spend per channel is small enough that nothing resolves, a read will tell you that and the correct answer is to wait. We publish two cases where the product was declined as premature on case studies for exactly that reason, and the arithmetic is in the measurability floor.
That is a real fit question and it is answerable before you spend anything, using the interactive demo and your own spend figures.
The line to run this week
Monthly ad spend, the claim ratio, and your retention setting. Three numbers, twenty minutes, and they tell you whether waiting is a decision or a default.
