Start with the questions you already receive
Read through recent support emails or messages. Look for the questions people ask more than once: delivery timing, returns, billing, opening hours, and account changes. Group similar questions together, but keep different policies separate. A delivery estimate and a delivery guarantee are not the same thing.
Write one answer that stands on its own
Give each question a direct answer. Start with the decision or action a customer needs, then add conditions and exceptions. Replace “soon” with a specific timeframe when you can support one. Explain when that timeframe starts. Avoid sending customers through a chain of links just to understand a basic policy.
Make ownership part of the document
Each policy should have an internal owner who can confirm it is current. Keep a reviewed date where your team can find it. When a policy changes, update every place that repeats it. Conflicting copies create conflicting answers, regardless of how capable your search or AI system is.
Separate public answers from private information
A public support knowledge base should not contain customer records, passwords, API keys or internal-only notes. Create a public version of a document instead of assuming a tool will reliably hide sensitive passages. If a question requires identity verification, write a safe route to human support rather than including account-specific instructions.
Test the question, not just the document
Ask someone who did not write the policy to find an answer. Try the language customers actually use, including short or incomplete questions. Check whether the answer still makes sense without surrounding context. Treat a failed search as a useful signal: rewrite the heading, add a common phrase, or clarify a missing condition.
Keep the first version small
Begin with your most common, stable questions. Review them when your business changes and when customers show you a gap. A short, maintained knowledge base is a better support foundation than a large collection of uncertain information. The goal is not to document everything—it is to make reliable answers easy to find.
