A WIP report answers a specific question across every open job at once: are we billing ahead of the work (over-billed) or behind it (under-billed)? It's a standard financial control in construction accounting precisely because job costs and billing rarely move in lockstep.
Pulling one manually means reconciling percent-complete estimates against every pay app across every active job — the kind of task that gets described as needing to be 'semi-automated' because doing it by hand every month doesn't scale past a handful of jobs.
Example
A GC's WIP report shows a $500,000 job at 70% cost-complete but only 55% billed — $75,000 of earned revenue sitting unbilled, which explains a cash crunch that would otherwise look like the company just isn't profitable.
