At-a-Glance Comparison
| Copilot | Price | Use Case | Audience |
|---|---|---|---|
| Microsoft 365 Copilot | $30/user/mo | Productivity (email, docs, meetings) | Every knowledge worker |
| Copilot for Sales | $50/user/mo standalone, $40 with M365 | Sales-CRM workflows | Sales reps |
| Copilot for Service | $50/user/mo standalone, $40 with M365 | Customer service agent assist | Service reps + field |
| Copilot Studio | $200/mo + consumption | Custom agent building | Business analysts + devs |
| Security Copilot | $2,920+/month (1 SCU min) | SOC + incident response | Security analysts |
EPC Group Decision Framework
1. M365 Copilot first. Every Copilot rollout starts here. Foundation.
2. Add Copilot for Sales if Dynamics 365 Sales OR Salesforce + dedicated sales force exists. Without an active CRM workflow, Copilot for Sales is wasted.
3. Add Copilot for Service if Dynamics 365 Customer Service OR ServiceNow OR Salesforce Service Cloud is the primary service platform.
4. Add Copilot Studio if 5+ custom agent use cases identified. For 1-2 custom agents, M365 Copilot extensibility is sufficient.
5. Add Security Copilot if SOC team has 5+ analysts and mature Sentinel + Defender deployments. Below that, the consumption cost is hard to justify.
