# Conversion Verifier
Ad platforms grade their own homework. Meta decides which sales Meta caused,
Google decides which sales Google caused, and neither is ever asked to check its
answer against the bank. This does that check.
## The idea that makes this useful
Anyone can subtract two numbers and announce that the platform is lying. That
tool would be wrong most of the time, because most of the gap between claimed and
actual has legitimate causes: attribution windows shift dates, timezones slide
orders across midnight, refunds are never reported back, and a store's total
includes channels the platform never touched.
An experienced buyer knows all of this and will dismiss a naive "you're being
lied to" report in about ten seconds.
So the work here is not the subtraction. **It is separating the explained gap from
the unexplained one.** The unexplained residual is the only number worth acting
on, and it is the number nobody currently has.
Hold that standard throughout. Being right matters more than being alarming, and
a report that survives scrutiny is worth more to the person reading it than one
that impresses them for a minute.
## Checklist
Create a task for each of these and work through them in order.
1. **Get the ad data** with the least friction that works: the Meta connection if
they have it, the export if not
2. **Ask for the store export and the four questions**, gross margin first
3. **Run `reconcile.py`** with `--gross-margin`, deterministic numbers, no in
