SYNTHETIC PROOF WALKTHROUGH

Block a subcontractor application that exceeds the supplied commitment

A synthetic construction AP preflight over supplied commitment, change-order, retainage, and project evidence.

NO KEY · NO UPLOAD · NO CUSTOMER DATAThis demonstration runs entirely in your browser using the visible synthetic fixture below.

THREE STEPS

Put the control before the consequential action.

Projected billed-to-date is 1,200.00 USD against an approved supplied commitment of 1,100.00 USD.

  1. 01

    Supply the project packet

    The caller provides the application, commitment, approved changes, billed-to-date, retainage, and supplied compliance status.

  2. 02

    Evaluate fixed controls

    The API computes projected commitment and retainage while checking supplied schedule, work, waiver, and insurance evidence.

  3. 03

    Block the overrun

    A projected commitment overrun returns BLOCKED with both calculated amounts for project and AP review.

WHAT THIS PROVES

Evidence for a stop point—not permission to act.

The control does not connect to construction software, validate a waiver or insurance policy, approve a change order, certify work, or route payment.
