Oxflow™

Construction Cost Management Platform

Phase 1 Milestone Plan — Prepared for Oxcon

Following our initial workshops and presentation, this document outlines the complete Phase 1 plan for Oxflow™ — a purpose-built construction cost management platform designed to replace Benchmark Estimating and integrate with your existing Workbench environment.

Oxflow brings together estimating, forecasting, variation management, and AI-powered reporting into a single modern web platform — built specifically for the way Oxcon operates. The detailed function list at the end of this document provides a complete inventory of every feature included in Phase 1.

Future Roadmap — Phase 2

Cost Management

Scope and timeline to be defined during Phase 1 workshops

Goal — Replace Workbench with integrated cost management and accounting

FeatureDescription
AP ApprovalsPurchase order workflow with approval tiers
Invoice ProcessingInvoice upload, matching, and coding
SubclaimsSubcontractor payment claim management
Cost CodingReal-time cost capture and allocation
Xero IntegrationBi-directional accounting sync
Tender CRMPipeline tracking, win/loss analysis
End State — Workbench is fully replaced. Oxcon runs entirely on Oxflow™ for estimating, forecasting, cost management, and accounting integration.

Estimated investment: ~$53,000 (approximate — final scope, timeline, and pricing to be confirmed during Phase 1 workshops).
