Construction finance tools

Why these tools exist

Pay-application math and lien deadlines are the two places where money quietly leaks on a construction project. A G702 with a transposed retainage figure or a misapplied stored materials line carries forward draw after draw until someone reconciles it, and by then the payment chain is six weeks downstream. A missed preliminary notice or a lien deadline counted from the wrong trigger date can erase a sub's right to claim altogether. We built these calculators because every general contractor, owner, and subcontractor we talk to needs them, no one wants to gate them behind a sales call, and the spreadsheets floating around the industry are wrong often enough to be dangerous.

The Pay App Calculator verifies AIA G702 summary math: original contract, change orders, completed-to-date, retainage, stored materials, and balance to finish. Paste in your numbers and the calculator will flag arithmetic that does not reconcile against the schedule of values. The Lien Deadline Calculator covers all 50 states and the District of Columbia: select your state, enter your project trigger dates, and you get preliminary notice windows, mechanics lien filing deadlines, and enforcement deadlines. We update the statute references as they change.

If a tool returns a number that conflicts with what your attorney or controller has, trust them, not us. These are reference calculators built for speed, not legal advice.
