# Internal Documentation

Internal documentation is everything your agency knows about itself. **It's the stuff you'd need to onboard a new co-founder**—not the marketing site, not the client work, but the real understanding of how the business actually runs. Which clients pay on time. Why you stopped using a particular vendor. How you handle the edge case that comes up twice a year.

The problem with internal documentation isn't that agencies don't write anything down. Most do. What gets written down is almost always the wrong thing. The welcome packet is polished. The process doc is detailed. But the **actual running understanding of the business**—the notes that explain why, the context that tells new hires what to avoid—tends to live in people's heads and leave with them.

Good internal documentation isn't formal. It's the Slack thread where a senior strategist explained the reasoning behind a pricing decision, captured before it scrolls away. It's the voice note an account manager recorded after a difficult client call. It's the retrospective observation that never made it into a doc because nobody had time to write it up cleanly. **The most useful internal knowledge is the messiest**—caught in the moment, not reconstructed later.

heykiku treats internal documentation as a capture problem, not a writing problem. Speak a thought and it becomes searchable knowledge. Upload a messy retrospective and it becomes answerable queries. With role-based access, sensitive internal context—pricing logic, partner disputes, client frustrations—stays visible to leadership while general process knowledge reaches everyone who needs it. **Documentation becomes a byproduct of the work, not a task you owe yourself.**
