How to Build a Call Center Knowledge Base

Step 1: Identify Common Customer Queries

The very first step is finding the customers' queries and issues. You can start by collecting data from:

• Call recordings
• Chat transcripts
• CRM notes
• Agent interviews

Always look for patterns. What questions keep coming up? These should be your first content priorities.

• Troubleshooting
• How-To Guides
• Billing & Payments
• Policies & Procedures

• Problem statement
• Step-by-step resolution
• Visual aid (screenshot or video)

• Infographics for step-by-step guides
• Videos for feature walkthroughs
• Decision trees for complex troubleshooting
