Best Practices:

• Apply human judgment to strategic decisions
• Maintain personal touch in relationship building

Integration Complexity

Connecting AI models to existing sales tools requires technical expertise. Start with platforms offering pre-built integrations before attempting custom development.

Cost Management

While AI reduces labor costs, model usage fees add up quickly. Monitor spending by:

• Setting usage limits per team member
• Optimizing prompts to use fewer tokens
• Choosing the most cost-effective model for each task
• Caching common queries when possible

Deeper CRM Integration: Native AI features in major CRM platforms will eliminate the need for separate tools.
