My experience with customers has been that nothing mattered except 
getting the system delivered.
In the specific projects I'm working on it's even sensible that way. It 
is business programming with non-critical data, like sales personnel 
reports and similar stuff. The cost to get the bugs out of the system 
can surpass the cost of experiencing an occasional bug.
Depending on the type of bug, of course. I'm aware of one case where a 
report got lost due to a bug in badly-designed and 
less-than-thoroughly-tested software. The company may have lost a 
contract worth a few million ("may" because the company might not have 
gotten it anyway).

Regards,
Joachim
