What Is a Single Source of Truth?
A single source of truth (SSOT) is one authoritative system where a given piece of data lives and is trusted across the whole organization. In RevOps it usually means the CRM: every team reads and writes customer data in one place, so reports don't disagree.
Key takeaways
- An SSOT is the one trusted, authoritative place for a piece of data.
- It eliminates conflicting numbers from siloed tools and spreadsheets.
- For most revenue teams, the CRM is the single source of truth.
Why it matters
When Marketing, Sales and Finance each keep their own version of “pipeline” or “customers,” every meeting starts with arguing about whose number is right. A single source of truth ends that: one definition, one system, numbers everyone trusts.
How to maintain one
- Integrate tools into the CRM rather than letting data fork.
- Enforce data hygiene — dedupe, validation, governance.
- Agree shared definitions for key objects and metrics.
