How to Use Copilot Custom Prompts and AI Builder in Dynamics 365 Sales

This blog builds on our previous article, How to Configure and Use the Prompt Column in Dataverse, which you can read here. While that post focused on the setup and core concepts of the Prompt column, this article delves into how you can boost sales efficiency using Copilot custom prompts and AI Builder inputs.

Sales teams today face increasing pressure to deliver personalized, timely, and accurate communication.

According to industry studies, sales reps spend up to 30% of their time on administrative tasks instead of engaging customers.

To reduce that burden, Microsoft Dynamics 365 Sales introduces Copilot in the Prompt column, empowering teams to generate tailored content with custom prompts and AI Builder inputs.

This blog explores how to use these features to boost

  • Sales efficiency
  • Customer engagement
  • CRM automation.

Why Copilot with Custom Prompts Matters

Sales professionals often need:

  • Quick summaries of opportunities.
  • Consistent follow-up emails.
  • Tailored content generation.

With Copilot custom prompts, users can instantly generate context-aware outputs, saving time and improving accuracy.

Example Sales Scenario

A Sales Manager preparing for a client meeting wants a quick overview:

  • Opportunity Name: 5 Café BG-1 Pro Grinders for Northwind Traders
  • Estimated Close Date: July 17, 2025
  • Description: Supply coffee machines for their new building.

Instead of searching across multiple fields, Copilot can instantly create a summary or even draft an email, ensuring the Sales Manager focuses on the client conversation—not data entry.

  1. Open the Copilot panel in Dynamics 365 Sales.
  2. Click the three dots (⋮) → Select Clear Prompt.
  3. Open Settings → adjust as needed → Close Settings.
  4. The Copilot tab appears at the bottom → enter your custom prompt.

💡 Pro Tip: Specify an output format (text, JSON, or document) when writing your prompt, and Copilot will automatically generate the response in that format.

  • Text Inputs: Customer details, deal information, notes.
  • Image/Document Inputs: JPG, PNG, PDF (up to 25 MB).
  • Dynamic Values: Power Fx formulas for logic-driven inputs (e.g., dates, calculated fields).
