A tech discovers extra scope on-site — a corroded pipe, an unplanned material upgrade, an additional hour of labor. He calls it in verbally. The customer nods. The invoice comes out two weeks later with line items nobody recognizes. Zero Double Entry means scope changes captured in the field flow directly to the invoice with a digital approval trail.
Key Finding: Independent workflow analysis indicates that unresolved change order management issues in Security Systems Installation operations hinder efficiency. Research shows that Contractors write off up to $15,000 annually in unbilled scope changes due to missing on-site digital signatures and approval trails [1].

Security system techs install and service systems where a single undocumented programming change or an incomplete UL inspection record can void a customer's insurance coverage. Paper as-built drawings, test result forms, and access change logs that don't make it back to the office leave the contractor unable to defend their work when a system fails or an insurance claim is disputed.
Objective third-party statistics and research benchmarks relative to change order management and security systems installation workflows.
A security tech running a camera cable discovers the conduit path requires an additional junction box not in the original design. He calls the project manager. Verbal authorization given. The $240 extra is on the invoice. The general manager disputes it at final billing.
Field design change orders on security installation projects are disputed on 20–35% of final billings when no signed change order is in the project file — especially at commercial accounts with procurement controls.
Undocumented change orders are the #1 source of invoice disputes. The average disputed amount is $1,200–$4,000 per incident. At 5 disputes per month, that is $72K–$240K/year in contested revenue.
These tools are great at what they do — but they don't eliminate the change order management gap. That's what we build.
We study exactly where change order management happens in your security systems installation operation — the forms, the handoffs, the re-entry points.
Not a demo. Not a slide deck. A real, functional prototype that eliminates the pain point and works with your existing tools.
You test the prototype on a real job. If it doesn't eliminate the change order management problem, you don't pay.
