Whetstone embeds senior operators inside contractors, engineering and AEC firms to control change orders, protect cash flow, and keep projects on schedule and budget — so thin margins survive contact with the field. Business-side only: we never touch engineering sign-off or site safety.
Thin margins die by a thousand cuts — overruns, missed change orders, trapped cash. We find the operational wounds and close them.
Keep projects on time and budget; kill overruns before they compound.
Capture every change and bill it — stop revenue bleeding on the job.
Free trapped cash: retainage, WIP and slow pay-apps.
Tighten buyout, vendor spend and sub coordination.
Make Procore, Sage and your stack give one reliable version of the job.
Our operational practice examines all 8 business systems to treat root causes — with fixed scope, fixed price, zero vendor commissions, a 30-day defect-fix window, and a 90-day follow-up.
"Where does it hurt?" Free consultation.
Diagnostic across all 8 systems.
Written findings & ROI — yours to keep.
