HVAC Flat-Rate Pricebook & Margin Guard

Build an owner-controlled HVAC flat-rate pricebook from your real business costs—and keep pricing risk visible.

Model labor, overhead, materials and direct costs, then use margin, freshness and component-exposure controls to surface service rows that need review before they are treated as ready.

Best for: solo and small HVAC owners who want to own their service definitions and pricing assumptions instead of relying on a generic market-rate list or managed catalog.

Boundary: this is not a prebuilt OEM task catalog, supplier-price feed, market-rate authority, accounting system or automatic price-setting engine. Published sell prices remain owner decisions.

The strongest private R&D successor is v2.57.1 — Aging Exposure + Version Identity Hardening. v2.57.1 is not yet the file delivered with purchase; real repeated-use/accessibility, real successor support/update burden and buyer/WTP evidence remain open.
