Build a Cost Library Your Team Can Trust
Construction Cost Database Software
Create a shared construction cost library for labor, materials, equipment, services, and assemblies. Erro helps contractors turn consistent pricing inputs into estimates, proposals, and documented revisions.
Solving Real Problems for Your Team
Our platform is designed to address the unique challenges faced by owners, managers, estimators, sales teams, and clients—empowering everyone to achieve better outcomes, together.
Start with a usable library structure
Organize the items your team quotes most often by trade, service, or project phase. Give each item a consistent description, unit of measure, direct cost source, and review date before trying to build a database for every possible scenario.
Standardize descriptions and units
Group items by trade or scope
Separate labor, materials, equipment, and services
Record the source and review date for important costs
Turn recurring work into assemblies and templates
Bundle the labor, materials, equipment, and assumptions that commonly appear together, then use those assemblies as the starting point for repeatable estimates. Estimators can adjust quantities and job conditions without recreating the underlying scope.
Create reusable sales assemblies
Use templates for common job types
Adjust quantities for the project at hand
Preserve the assumptions behind each estimate
Set a clear process for price updates
A cost library stays reliable when someone owns updates. Define who can change an item, what evidence is required, which costs need frequent review, and how the team communicates a meaningful update before it affects new estimates.
Assign an owner for library maintenance
Review supplier, labor, and equipment inputs on a schedule
Document why a material price or assumption changed
Confirm job-specific quotes before sending high-risk bids
Keep cost inputs separate from pricing decisions
Direct cost is only one part of a selling price. Keep delivery, waste, labor burden, site requirements, overhead, risk, and target profit visible so an update to a supplier cost does not erase the logic behind your price.
Review fully loaded labor costs
Apply allowances and waste deliberately
Document overhead and risk assumptions
Use estimate reviews before issuing a proposal
Move cost data into the work your team sells
A cost database should reduce duplicate entry, not become a separate maintenance project. Use it as the starting point for estimates, preserve revisions when scope changes, and create client-ready proposals from the approved pricing.
Build estimates from shared library items
Keep estimate revisions visible
Generate connected proposals
Test the workflow with a real recent estimate
