# Map a Google Ads account hierarchy

> Tier: recipe. Operating recipe: real tool sequence, core rules, known traps.

The account hierarchy under a manager, with account details and currencies per node.

**Intent.** The MCC tree with names, so nobody works on IDs.

## When to use

- Agency onboarding.
- Before cross-account reporting.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: Google Ads

## Preconditions

- The account is ticked in the dashboard, confirmed via list_accounts.

## Inputs

- `window`: Analysis window. Default: last 30 days.

## Procedure

1. Walk the hierarchy from the manager. — tools: `google_ads_get_account_hierarchy`
2. Pull details, currency and timezone per account that matters. — tools: `google_ads_get_account_details`

## Decision rules

- **When** Accounts under the MCC differ in currency or timezone → **conclude** Every future merged table must convert or label: record it now, in the map.

## Evidence requirements

- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.

## Human approval boundary

- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.

## Failure modes

- Manager access does not equal ticked access: the gateway answers only for ticked accounts, and the map must say which.

## Output

- **Readout**: The figures, with windows and accounts named.
- **Flags**: What deserves a deeper skill or a human decision.
