Put in your own real numbers — nothing here is a guess or an "average client" claim, since we're a new consultancy and don't have those yet. This just does the arithmetic honestly.
Quoting, booking, chasing invoices, answering the same questions — anything that isn't the actual skilled work.
What you'd pay someone to do it, or what your own time is worth doing something else instead.
Used only to point you at the right pricing tier below.
