A report finished on site can go to the client or general contractor the same afternoon, which means the invoice goes with it. Documentation that waits for a slow evening at the office is an invoice that waits with it, and a job you finished in May that bills in July. What a Site Record Actually NeedsStrong job documentation, on paper or in an app, carries the same things every time:A location. Most don't, because the manual version is slow, and slow documentation is the first thing to go on a busy week. I spent 15 years engineering HVAC and plumbing systems, and I hit the documentation problem on every job; my co-founder handles the software.
