You change partners, but that usually means it's the same partner working in the same group and so all know each other really well. Also, that doesn't mean anything since the team can stay the same. Partners would question the work and can look at it, but rarely any partner would bother to go into the bank statement and make sure the work is tied out. They are too "above" that. That responsibility falls onto the senior and managers, and in many instances incompetence or laziness from those staff will let things go through. It's very tedious work, and it's annoying to do the same thing for 8+ hours a day for a month or two. In the end, the team just want things to tie out, and make whatever documentation is necessary to make sense of things. No need to upset the client or partner and lose the potential business.
