The usual signal is a backlog. Invoices go out late, claims sit unchecked, and the person who runs the business spends evenings rekeying data between systems. Hiring an admin is the obvious fix, and sometimes it is the right one. The trouble is that a lot of admin scales with volume, so every new customer adds the same fixed block of work, and the hire you make this year becomes two hires the year after.
The better question is which parts of the admin need a person at all. Answering phones, chasing a difficult debtor and calming an upset customer need someone who can read the room. Matching an invoice to a purchase order, checking a claim against a budget and copying a booking into the accounts system do not.
