Ex-Accenture here. Software devs (at the grunt level at least) would almost never work for another client at the same time as your main client. I only ever met one person who worked for two clients simultaneously, and IIRC they were management/admin level. As far as I know, they didn't file double-time as described in your comment. Internally, the hour billing tracker (disgusting old thing) would limit you to 8h per day total anyway, so you couldn't just bill 8h to Project 1 and another 8h to Project 2, because it would scream at you that you're trying to file for unapproved overtime (which would cost ACN money). It's anyone's guess how this data would be presented externally to the client, but I like to think that they wouldn't bill for 8 hours externally when the internal record shows only 4 hours was worked.
