Every small business has one.
The person who knows how billing actually works. Not the official version
the real one. Which client needs the PO on the invoice line. Which portal breaks if you upload before noon. Who to email when a payment posts to the wrong account.
None of it is written down. All of it is load bearing. And then that person takes a vacation. Or gets sick. Or gives notice.
I've watched a company lose two weeks of cash flow because one person was out and nobody else knew the workaround for a single client portal.
Documentation isn't bureaucracy. It's insurance.
If your operation would stumble when one specific person is unreachable, you don't have a process. You have a dependency.
Write it down. Then make it findable.
