Salesforce is a powerful platform for lead qualification and scoring, as it centralizes all lead, contact, and account information. By building a lead scoring process within Salesforce, users can enhance data with demographic attributes and include sales activity in scoring formulas. It is recommended to start with a basic model and gradually refine it based on the ideal customer profile and predictive activities, especially in the B2B SaaS market. Integrating tools like Clearbit can enrich Salesforce records with personal, social, and company information, facilitating the creation of a custom lead score using a custom field and Apex code. This process, which is simple to set up, significantly improves the quality of leads sent to sales representatives, ensuring that only the most relevant leads are pursued, thus saving time and resources. The setup involves creating a custom formula field and modifying pre-built Apex code to accommodate specific requirements, enabling effective lead routing, prioritization, and reporting.
