Does Meta not do this for free with automated rules?
Partly, yes. Meta and Google can both pause and change budgets automatically, at no cost. What they do not do is enforce a volume or significance threshold: you set a rule yourself and it fires on the raw numbers you give it. That is exactly how you end up pausing ads that happened to have a bad week, and scaling on three coincidental conversions. The difference is the calibration against your real order value, and keeping it maintained.
What does it cost?
The diagnostic is 3,500 euro and the installation 4,500 euro, both one off. Monthly monitoring is 2,500 euro or 7 percent of the managed ad budget, whichever is higher, plus a share of revenue growth above a baseline we agree before the start. At forty thousand euro of spend a month you land on the floor of 2,500 euro.
What if it does not work?
On the diagnostic: if we find no fivefold room to improve, you do not pay. On the monitoring we agree a gate together in week two, for instance that no ad runs more than fourteen days above its cost threshold without an intervention. If that gate stays shut through something on my side or the system's, the monthly fee does not run until it is resolved.
Does the system touch my budgets by itself?
No. It measures, judges and proposes; I decide and execute. Two components may switch an ad on or off inside fixed limits, and those limits are written down: never below two live ads per ad set, never your best ad, at most one swap per ad set at a time. The system never touches budgets on its own.
What happens to my data?
Before the first call you sign one page setting out what I will not do: copy nothing, keep nothing, change nothing, and no sub-processor touches your data. If an engagement starts, a full data processing agreement follows with the sub-processor list in it. The working files hold aggregated figures only, never names or addresses of your customers.
Do you replace my current agency?
Not necessarily. At many brands this runs alongside as a second, independent layer: you get a number you can read back instead of a report you have to believe. If that shows the agency could do better, that is your conversation and not mine.
