What Is a Single Source of Truth?
A single source of truth (SSOT) means each fact your business depends on lives in one system, and everything else reads it from there. When two systems both hold the same fact, they eventually disagree, and someone has to decide which one is right.
It does not mean one system for everything. It means one home per fact.
Which System Owns What at an IT MSP?
| Fact | Its home |
|---|---|
| Deals, stages, amounts, and close dates | The CRM, such as HubSpot or Salesforce |
| Contacts, companies, and sales activity | The CRM |
| Tickets, agreements, technician time, and invoices | The PSA |
| Quotes | The PSA or a separate quoting tool |
The two meet at the close. The deal is won in the CRM, and the new client is set up in the PSA before service starts.
Why Does the CRM Stop Being the Source of Truth?
Usually because keeping it current is extra work that nobody has time for. Calls happen and never get logged. A deal moves forward in an email thread while its stage sits where it was a month ago. A rep keeps the real forecast in a spreadsheet.
Then the pipeline report and the reps tell two different stories, and the pipeline meeting turns into reconciling them. That gap is a data silo between the conversation and the CRM.
How to Keep the CRM Worth Trusting
- Decide which system owns each fact, and write it down.
- Keep the required deal fields few: amount, stage, close date, and next step.
- Log activity where it happens, without anyone retyping it.
- Review stale deals every week, not every quarter.
