Definition
“Closed-won” signals the transition from selling to serving. The baton passes from sales to customer success, onboarding begins, and the customer relationship enters its long-term growth phase.
Closed-won vs. closed-lost
In CRM systems like Salesforce or HubSpot, deals are usually categorized as either:
While closed-lost triggers post-mortem analysis, closed-won should trigger activation and retention planning.
Why “closed-won” matters beyond celebration
For SaaS companies, the sale is, in fact, the starting line for revenue realization. Marking a deal as closed-won has ripple effects across the org:
- Finance: Recognizes ARR or MRR and forecasts cash flow.
- Customer Success: Initiates onboarding and adoption tracking.
- Product: Gains insights from use cases and customer feedback.
- Marketing: Captures testimonials or case study opportunities.
What happens right after a deal is closed-won
High-performing SaaS teams follow a process:
- Customer handoff: Sales shares context—pain points, goals, stakeholders—with the success team.
- Onboarding kickoff: Customer success sets expectations, milestones, and usage targets.
- Internal review: Sales updates CRM with key notes and lessons learned.
- Recognition: Celebrate wins, but document learnings for replicability.
- Post-sale engagement: Marketing captures early stories and feedback.
This structured follow-through ensures customer satisfaction starts on Day 1.
Mistakes to avoid while tracking closed-won
- Prematurely marking deals closed-won: Deals should move only when contracts are signed and legal/finance confirms.
- Weak handoffs: Lack of context between sales and success leads to rocky onboarding.
- No win analysis: Teams celebrate but never study what worked.
- Ignoring early churn risk: The first 30 days after closed-won determine long-term retention.
