Thirty minutes on a fictional project at your GMP size.

We open the nine modules in order, show the month the contractor's fund runs out, and show what the first monthly report would contain. No slides. Then you ask the security and pricing questions.

A person reads every message that arrives here and answers within 48 hours on working days. What you write is stored on our own server and is never sent to an external AI service.

What happens on the call

We open a fictional project at your GMP size and contract form. Baseline first, then the contingency ledger and the exhaustion month, then the change order register with its causes, then buyout, allowances, anticipated final cost and shared savings. We end on the monthly report and the one pager. You keep the sample PDF.

Under $5 million

Below that size the setup costs more than the exposure it protects, so the subscription is not offered. Write anyway if you have a contract question. The free tools and the articles are for you.

Owner's representatives

Say how many owners and projects you manage. The portfolio view and the per owner report are the first things we show. Read the page for reps.
