Managing multiple projects in the construction industry requires financial oversight and real-time performance tracking. The Work-In Progress (WIP) schedule is a critical tool for a contractor to understand how their projects performed or are performing, management decision-making, financial reporting and to ensure the company remains profitable.
There are contractors that believe the AIA document that is sent monthly helps to manage projects. Although the AIA is great for tracking billing, this document does little to support the actual management of a construction job. The AIA document does not provide insight into cost performance, productivity, remaining cost to complete, or project profitability and can be misleading if billings are ahead of or behind actual performance.
We have seen in practice where WIP schedules are not periodically prepared, or the contractor uses some other form of tracking (AIA form or cash in bank), to find out at year-end that a job or several jobs have job-fade, break even or lose money. This does not bode well for the owner, if bonding is involved, or there are bank covenants for outstanding loans.
Contractors that use WIP schedules regularly can identify issues early and make informed decisions before problems grow. Projects that show margin erosion/cost overruns, underbillings, or inconsistent remaining costs to complete signal the need for immediate attention. Management can determine whether corrective action is needed, such as adjusting subcontractors or the company’s manpower, address productivity issues, pursue change orders, or consider revising project forecasts. The WIP schedule also helps contractors evaluate backlog, which for any contractor, if there is no backlog, there is likely no future for the construction company.
For project managers or superintendents, the WIP schedule reinforces accountability. It highlights variances between estimated and actual costs, forces regular reviews of remaining cost projections, and percentage of completion tracking. When project teams understand how their forecasts affect company results, they are more likely to manage more proactively. This ongoing monitoring helps contractors avoid surprises at project closeout and supports consistent project management.
Cash flow is a constant concern for contractors, and the WIP schedule plays a direct role in managing it. When tracking overbillings and underbillings properly, contractors can identify billing opportunities or potential cash shortfalls. Accurate WIP schedules ensure revenue, costs and profit are properly recognized, reduce the risk of overstated earnings or unexpected losses, and essential for maintaining strong relationships with bonding companies/sureties and lenders, who rely on this information. In addition, the WIP schedule is essential for preparing accurate financial statements.
For contractors, the WIP schedule is not just an accounting exercise, it is a critical management tool. When used consistently and reviewed honestly, it supports better decision-making, stronger project control, and more reliable financial reporting. Contractors who treat the WIP schedule as an operational asset, rather than a monthly requirement, are better positioned to manage risk, maintain cash flow, and deliver profitable projects.
