How does poor expense management affect WIP reporting in construction?

Key takeaways

• Unrecorded field expenses create gaps in WIP schedules, understating costs-to-date and distorting percent-complete calculations.
• Manual, delayed coding means WIP reports rely on outdated information, reducing their usefulness for project decision-making.
• Miscoded expenses assigned to the wrong job or cost code make WIP reporting unreliable and require time-consuming reconciliation.
• Incomplete expense data delays monthly close and creates compliance risk during audits of over-billing or under-billing positions.
• Vergo captures transactions in real time and proposes coding by inference from your accounting structure, ensuring WIP schedules reflect all project costs as they occur without manual delays.

Why construction expense management creates WIP reporting problems

Construction expense management is uniquely challenging due to distributed job sites, disconnected field and office workflows, and reliance on manual, paper-based processes. Superintendents often purchase materials at local suppliers and lose the receipts, never getting those expenses back to the office. ERP systems struggle to capture all field-level spending in a timely manner, leading to incomplete data that flows into WIP schedules. The disconnect between when costs are incurred and when they appear in accounting means WIP reports reflect only a partial picture of project status, making percent-complete calculations and over/under-billing positions unreliable until reconciliation catches up weeks later.

The consequences for financial reporting and compliance

Inaccurate WIP reporting stemming from poor expense management has serious consequences for construction companies. Distorted job costing and profitability analysis make it difficult to identify problem projects before they erode margins. Unreliable forecasting of project completion dates undermines cash flow planning and resource allocation. Compliance issues emerge during audits when reported costs-to-date do not match actual spending, creating risk around revenue recognition and over-billing positions. Delays in monthly financial close and reporting extend the time finance teams spend reconciling discrepancies instead of analyzing results. These gaps also reduce visibility into cash flow, making it harder to manage working capital across a portfolio of projects with different billing schedules and payment terms.

A practical example

A superintendent purchases lumber and fasteners at a local supplier for an urgent repair on a commercial build. The receipt sits in his truck for two weeks before making it to the office, where accounting codes it manually and enters it into the ERP. By the time the expense appears in the general ledger, the monthly WIP report has already been prepared and distributed to project managers and ownership. The report shows the project at seventy-eight percent complete based on incomplete cost data, suggesting healthy margins. When the missing expenses finally post the following month, the true percent-complete drops to eighty-two percent with costs exceeding the original estimate, requiring an explanation to the bonding company and triggering a review of all outstanding field purchases across the portfolio.

How Vergo handles this

Vergo captures transactions the moment they happen, with no waiting for clearing, so WIP schedules reflect current project costs in real time. Employees handle everything by text message, including receipt submission, so field teams document purchases on-site without app downloads or portal logins. Vergo proposes the coding by inference from your accounting structure and history, assigning job number and cost code on first sight of a new vendor, and every coding shows why it was chosen so reviewers confirm in seconds instead of re-coding by hand. Approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project, or skip approval flows entirely and let policy flags catch only what breaks a rule. Card spend, employee reimbursements, and AP invoices run through one coding model, creating one reconciliation process and ensuring WIP schedules include all project costs regardless of payment method. Connecting your existing cards involves no card applications, no re-issuing, and no banking change, and once transactions clear they sync into your accounting or ERP software.
