What the audit covers
A martech stack audit answers four questions in writing: what do you actually run, what does each platform cost against what it delivers, where is the overlap, and where is the gap.
1. Inventory
Every platform in the stack, contract terms, renewal dates, and who inside the org actually owns and uses it day to day.
2. Integration mapping
How data actually moves between systems today - not how the architecture diagram says it should move. This is usually where the surprises are.
3. Gap and redundancy analysis
Where two tools are doing the same job (redundancy, a cost problem) and where a needed capability has no owner at all (a gap, a risk problem).
4. A prioritized fix list
Ranked by effort and impact, not just a list of everything wrong - with which fixes are a configuration change and which require a new platform.
What triggers an audit
The most common triggers we see: a vendor renewal coming up with no clear justification, a merger or acquisition merging two stacks, attribution numbers that stopped reconciling, or a new martech leader inheriting a stack nobody fully documented.
What you get at the end
A written report: the inventory, the integration map, the gap/redundancy findings, and the prioritized recommendations - in a format built to survive being handed to a CFO or a board, not just a slide deck for the marketing team.
