I’m not sure why, but clients seem to be more comfortable with odd numbers and specific amounts.

A project fee of $1730 sounds like it’s based on some calculations or considerations.

A project fee of $1600 sounds like a number you just made up.

A day rate of $1150 is somehow easier to swallow than a day rate of $1000.  Which sounds like a nice round figure that you feel like making.

When my auto mechanic charges me exactly $600 for my front brakes, I feel suspicious.  But I’ll gladly write the check for $731.45.
