Work in progress (WIP) schedules are used in construction accounting to track the status of ongoing projects. They record the costs incurred and work completed on a project that has not yet been finished. WIP schedules provide accurate financial reporting of project health, help control costs by identifying overruns, and assist with cash flow management by forecasting revenue. They are created by gathering project data, calculating costs and revenue, and determining the WIP value. WIP schedules are then used for financial reporting, cost analysis, auditing, and management decisions to improve project performance and business success.
