Copilot Custom Summaries: Turn Every Teams Sales Call Into a Deal Brief

The transcript of your last sales call knows more about the deal than your CRM does. It knows which competitor came up, who in the room actually owns the budget, and which objection went unanswered. Most of that intelligence evaporates because nobody has time to mine a transcript between meetings.

Copilot was already in that call. With one reusable custom prompt, it can hand your reps a structured sales brief the moment the recording ends, and this guide shows exactly how we set that up.

Why the stock recap is not built for sales#

Picture an account executive running 6 to 8 Teams meetings a day: discovery calls, demos, follow-ups. Every conversation carries intelligence that could move the deal forward:

• Who the real decision maker is
• Which competitors came up in conversation
• Whether the deal feels real or quietly at risk

Most of that lives in the rep's head and disappears before the next meeting starts.

Copilot's default meeting summary captures a general overview and some follow-up tasks, which is useful. But it is a generic template applied to every meeting regardless of context. For a sales team, that is not enough.

How to build a custom sales summary, step by step#

You need Teams Premium or Microsoft 365 Copilot, and the meeting must be recorded and transcribed.

1. Open the Custom Summary tab#

1. Click into a meeting that was recorded
2. Go to Recap, then Custom Summary
3. Click + Create Template

This is where you paste or build your own prompt instead of relying on the default template.

2. Start with a basic prompt#

A simple starting point:

You are a sales leader reviewing this meeting. Extract: top insights, company profile, competitors mentioned, deal risks/objections, and a confidence-based win rate with a closing action plan.

Copilot formats each section automatically and pulls from the actual transcript. No manual note-taking required.

Clicking Preview shows a sample output before you commit:

3. Add specificity to sharpen the output#

The more context you provide, the sharper the results. Instruct Copilot to:

• Extract specific company profile fields: team size, location, number of customers under management, tools currently in use
• Focus competitor mentions only on direct competitors, not internal tools the prospect happens to reference
• Return a numerical win rate with justification based on signals from the transcript, not assumptions

Here is the fuller prompt we use on our own sales calls:

You are a sales leader looking to get expert insights from this call. You want to pull out details on:
Top Insights - Keep these to concise bullets
Company Profile Info - Include: Team Size, Location, Users/Customers under management, and how they heard about us
Competitors Mentioned - Make sure you focus on competitors they mention directly to CloudCapsule, not tools they use internally.
Risks & Objections - Highlight deal risk and concise bullets on top objections.
Win Rate - A realistic confidence score based on signals, not vibes. For the win rate, outline what the rep needs to do to get the call closed and potential risk for the deal being lost. You should be more pessimistic here.

Plan to test your prompt across 5 to 10 different calls before finalizing it. Gaps and false positives surface quickly, and a few iterations tighten the output significantly.

4. Save it and reuse it everywhere#

Once you are satisfied, click Save and Apply and give the template a name like "Sales Discovery" or "Deal Review." It appears as a persistent tab inside your meeting recap view, ready to run on any future call automatically.

Three caveats before you roll this out#

• No recording, no summary. The meeting must be recorded and transcribed for Copilot to generate anything, default or custom.
• Demand pessimism explicitly. Win rate outputs work best when the prompt insists on pessimistic, signal-based scoring. Vague prompts produce vague confidence scores.
• Templates are per-user as of May 2026. Custom summaries are reusable across meetings, but they save on an individual basis. There is no org-wide template a whole team can see, so circulate the prompt text and have each rep paste it in once.

What this changes in practice#

That account executive from earlier ends the meeting, opens the recap, and a structured brief is already waiting: company profile, deal risks, competitor flags, and a confidence-based closing plan. Twenty minutes of note-writing disappears, the CRM update drops straight in, and the follow-up email practically writes itself.

That is not just a time save. That is a structural advantage in every deal cycle.
