A Close-to-Home Example: How CRM Works in a Software Company

In a SaaS company, the CRM system tracks a customer’s journey from the first contact to product use and ongoing customer support. Engineers often need to ensure that CRM and product data are tightly integrated to provide a comprehensive view of the customer.

Imagine a software development company that sells a SaaS product:

  1. The company uses a CRM system to track potential customers (leads), monitor their interactions with the product, and nurture them through the sales funnel. 
  2. When a lead expresses interest in a demo, the CRM captures this data and triggers an automated email campaign to guide the lead toward purchasing.
  3. Once the lead becomes a customer, the CRM continues to track their usage, preferences, and issues, providing valuable data to customer support and product teams. 

That’s why engineers are often involved in integrating the CRM with the product to provide insights that drive product enhancements or user experience improvements. They get to:

  • Build APIs that synchronize product usage data with the CRM. For instance, when a user logs in, their profile in the CRM should update, and the product team should receive data on feature adoption.
  • Implement webhook functionality that triggers notifications in CRM systems based on product milestones (e.g., a customer hits a new usage threshold, prompting a follow-up email or in-app message).
  • Store user activity logs in a centralized database that both product and CRM systems can query to assess customer engagement.

This close integration of CRM with the product and service ensures that customer data flows seamlessly, offering a holistic view of the user journey.
