WHY DEFINING IT MATTERS
Without a boundary, clients ask for everything and you absorb it.
HOW TO STATE IT
Plainly, in your terms and on your site.
WHAT TO SAY WHEN ASKED FOR SOMETHING OUTSIDE IT
"That is outside our hosting support, and I can quote for it separately."
Kind, and clear.
WHAT NOT TO DO
Absorb chargeable work to keep a client happy.
That establishes the expectation permanently.
