Most small businesses run on what's in a few people's heads. It works fine until one of those people is out sick, retires, or leaves. Then everyone discovers how much was never written down.
I've been on the receiving end of that. At one company, the administrator who held all the knowledge of how the business and its finances ran was stepping back. My job was to capture it before it walked out the door. We wrote what the team called “the bible”: how the business actually runs, step by step, and built processes where none had existed.
If it only lives in one person's head, it isn't a process. It's a risk.
You don't need a binder that nobody opens. Start with the tasks that would hurt most if they stopped. Write them click by click, test them with someone who has never done the job, and treat every conversation with staff as a training moment.
