Open Book Billing


Open Book Billing is a unique aspect of Piper Construction that offers significant benefits to you as a customer. In essence it means that you only pay for the exact work performed and materials used, and all the financial information regarding your job is available for your review. No more subjective estimates and no more wondering, with no explanation, what exactly you are being charged for.


Along with Open Book Billing we are committed to earning your trust by putting all of the surprise or sticker shock of your job at the beginning when you’re still making decisions about the job and none at the end. We will be honest with you at the outset regarding all job related costs, and there will be no surprises at the end of the job.

How We Bill Our Customers

How Does Open Book Billing Work?


1) You will receive a Guaranteed Maximum Price (GMP) Estimate. This estimate will specify all work to be done and provide a cost estimate that will be the most you would have to pay at the end. (Note: Any subsequent changes, additions, abatement, or unforeseen conditions not specified in estimate may cause the cost to exceed the GMP estimate.)


2) Accurate records of material cost, subcontractor cost, and hours of labor during construction will be maintained by Piper Construction.


3) Upon completion of work you may be provided with copies of all receipts and records of hours worked.


4) You will be billed for actual material cost + actual hours worked + business overhead+ 20% coordination cost, not to exceed your original GMP Estimate.
