What the week is actually made of #

What to do before you advertise #
The question is not whether to hire. It is what the person will be doing on a Tuesday afternoon in March. Two things are worth doing first, and both take less effort than writing the advert:
-
Count the week you are about to buy
Write down the jobs this role would pick up, how long each takes and how often it happens. The cost of admin time calculator adds it up and puts a cost on it.
-
Separate the pattern from the judgement
If most of the hours sit in the first list above, a hire will absorb the pressure rather than remove it, and the same pressure returns when the business grows again.
Plenty of businesses do both: automate the repeated half, then hire someone to do the half that needs a person, often part time or at a level that keeps them interested. That is a better job than the one the advert usually describes.
Where this role usually sits #
This job turns up most often in trades and installers , cleaning and facilities , logistics and haulage and wholesale , and the admin around it looks different in each.
