About

B2W Estimate software for heavy civil construction estimating and bidding designed to enable contractors to bid with speed, accuracy, and strategy. Users can pre-populate a centralized database with cost data and structures for labor, tasks, materials, and equipment and use these building blocks to complete bids. B2W Estimate boasts enterprise-class performance and scalability in combination with a Windows look and feel and construction logic. Pay-item, WBS, or hybrid bids can be completed, and multiple estimators can work on a bid simultaneously. Additional features include mobile estimating, vendor and subcontractor management, and cross-bid analysis and reporting. Within the B2W Software ONE Platform, the B2W Estimate can communicate detailed job information directly to B2W applications for scheduling and field tracking. The software also integrates with DOT electronic bidding systems and more than 30 accounting/ERP platforms.

About

Stairkey is an all-in-one business management platform for small construction, trades, and contracting companies. It combines estimating, invoicing, project management, accounting, and CRM in a single web app, so contractors can run a job from first quote to final payment without juggling separate tools. Build detailed line-item estimates and convert them in one click into invoices and fully scheduled projects — complete with tasks, subtasks, material and tool lists, and job costing. Track actual costs against budget, issue change orders, and coordinate crews and clients through a mobile portal. Built-in double-entry accounting handles sales tax, reconciliation, and financial reports. It also offers scheduling with route and weather planning, contact management, and an optional AI assistant connection via the Model Context Protocol.
