Construction Project Costing & Cash Flow System in Excel | BOQ | WIP | Job Costing | 13-Week Cash Flow

Description
The Construction Project Costing & Cash Flow System is a professional Excel-based management model designed for contractors, subcontractors, property developers, engineering firms, quantity surveyors, project managers, cost controllers and construction finance teams.

The system connects the complete commercial and financial lifecycle of multiple construction projects in one structured workbook. Users can maintain clients, projects and construction cost codes; prepare original and revised BOQ budgets; record change orders; monitor purchase orders and subcontract commitments; capture supplier costs and loaded labour costs; manage client billing and collections; calculate work in progress; prepare rolling cash-flow forecasts; and review project and portfolio performance.

The BOQ module provides project and cost-code level visibility over original budgets, revised budgets, commitments, actual cost, remaining commitments, estimate to complete, estimate at completion and budget variance. Change-order and commitment registers support better control over approved variations, supplier obligations, invoicing, payments and future project exposure.
The WIP module connects contract values, costs, commitments, completion percentages, earned revenue and amounts billed. It supports Manual, Cost-Based and Physical completion methods, enabling users to review under-billing, over-billing, forecast final revenue, forecast final cost, forecast gross profit and forecast gross margin.

A rolling 13-week cash-flow forecast summarizes expected project receipts and payments, closing cash balances, minimum cash requirements, cash surpluses and potential funding gaps. Project and executive dashboards present key performance indicators, risk tables and charts for management review.

The professional package includes an 18-worksheet Excel workbook, a detailed 35-page User Manual, an 11-page Quick Start Guide and a 20-page Product Preview. The workbook is 100% formula-driven, contains no VBA and has no external workbook links. It is designed for Microsoft Excel 2019 and Microsoft 365.
All included records and financial figures are fictional demonstration data and must be replaced before operational use. This workbook is a management planning and project-control model, not a statutory accounting ledger, ERP system or certified quantity-surveying application. Users must validate all data, assumptions, accounting policies, contract terms and outputs before making business decisions.
