Consultant not getting paid

[CoolRich59]

for those of you in the know about these things, is all the time he has to spend fighting for his payments billable on his time invoices?

In my experience, no. Normally, only project work is billable. I have seen travel time as billable, but that's pretty rare.

The assumption is that the hourly rate includes "administrative" stuff like time keeping and invoicing. (Of course, that is also based on the assumption that the invoices are being paid in a timely manner.)

I had one consulting firm send me a nice note telling me that, going forward, they'd be adding 5% to their invoices to cover their administrative costs. I told their client manager that we'd strike it from the invoice. I didn't hear any more about it.
