I actually sat in a meeting a few years back as a consultant - with 6-7 other consultants and 1 or 2 employees of the company we were assigned to - all billing $150 to $500/hr - as we discussed which cost center we could bill the $35/month SAAS tool we needed to use for the project we were developing. We probably spent 3-4 years with of those SAAS fees in that one 45 minute meeting discussing which cost center should be billed. Client (a fortune 50 company) didn't see any issue with this.
