Fixing Construction’s Margin Visibility Problem With ERP

The construction sector is facing the headwinds of economic turbulence, with factors from the rising cost of specialist materials to increases in business rates threatening margins and project timescales.

Global supply chain disruptions are also reshaping how construction professionals plan projects and negotiate with subcontractors. As external pressures mount, what might appear to be small internal cracks within large construction companies are becoming harder to ignore. These include strained enterprise resource planning (ERP) systems to disconnected workflows between departments.

For large construction businesses, which often operate multi-entity structures, manage multiple contract types and coordinate large subcontractor ecosystems across long project programs, the business impact of operational slip is clear: Margin exposure increases across complex, live projects.

These challenges create a growing demand for timely, reliable visibility of procurement, plant, supplier and project costs so decisions can be made with confidence, before commercial risk becomes financial reality.

One of the most effective ways to address this is with a system designed around the actual workflows it manages. A construction-specific ERP platform connects commercial, finance, procurement, supply chain and site workflows. It ensures approved records, evidence and decisions stay connected from the back office through to billing, payment and reporting.

While ERP platforms are not new to construction, the value comes from how they are applied. Systems built around construction workflows can give teams live cost-to-date visibility, support cost value reconciliation (CVR). This helps ensure valuations, variations and supplier records move together as one continuous process, which protects margin while maintaining commercial control.

Where Margin Starts Slipping

In large-scale construction projects, the challenge is delivery often leads and commercial control follows. Site teams make rapid decisions to maintain progress, such as instructing variations, while valuation, rate agreement and client approval are addressed later, creating a structural lag between action and financial control.

This report highlights this disconnect in construction workflows. Just 17% of construction organizations report almost all cost data is entered once and flows through to finance without duplication, meaning manual handling remains built into day-to-day operations.

In practice, a site manager may instruct a variation to keep work moving based on a verbal agreement. The commercial process follows after, but often without a clear audit trail attached to the original instruction.

For contractors, this creates timing gaps where work is completed before it is formally valued. Costs begin to accrue, but revenue is not recognized. Across a live project, that disconnect can distort margin position and weaken reporting confidence.

A similar challenge can occur for housebuilders managing large, multi-phase developments. Groundworks, infrastructure and vertical build activities overlap, with different subcontractors operating simultaneously. Keeping cost-to-date aligned with valuation across these moving parts becomes more difficult. This is especially true where approvals and supporting records are not consistently captured.

Developers rely on accurate, up-to-date financial information to manage funding, appraisals and investor reporting. When records lag behind site activity, the risk extends beyond individual projects to wider portfolio performance and reporting confidence.

Disconnected workflows become most visible when variations occur. Design changes, unforeseen ground conditions and client-driven amendments all generate additional work. The commercial risk is not the change itself, but how accurately it is captured, valued and approved with evidence attached.

In practice, variations are often recorded late. Site teams prioritize delivery, while commercial teams reconstruct events after the fact. Approval cycles slow, and the link between instruction, valuation and billing becomes harder to evidence.

All the while, costs continue to build. Subcontractors expect payment, materials are consumed and labor is committed. Without aligned records, revenue recognition can lag by weeks or months, increasing margin exposure.

Supplier Costs and Subcontractor Management Implications

Supplier and subcontractor management remains a critical pressure point in large construction organizations. Contractors often oversee multiple subcontract packages and each has its own valuation and payment cycle.

Applications for payment, valuations and invoices are often misaligned. Where subcontractor applications do not reflect actual site progress, or where invoices are delayed, finance teams are forced to rely on accruals and assumptions rather than verified records.

Accruals can bridge the gap, but they rarely provide full confidence. Across a large project portfolio, small inconsistencies can compound and erode margin before it becomes visible.

For housebuilders, this effect is amplified by scale and repetition. A minor discrepancy at plot level can multiply across hundreds of units, making it harder to maintain a clear view of committed versus actual cost.

Reporting That Falls Behind Site Activity

The cumulative effect of these gaps is a reporting cycle that trails behind the reality of a moving project.

Monthly valuations and cost reports remain central to construction finance. Yet by the time data is compiled, checked and circulated, the underlying position may already have shifted.

This creates a familiar risk. Project teams may believe they are operating within budget based on the latest report, while in reality costs have already moved on and margin exposure is building.

Our recent report shows this trend where construction companies often rely on reconciliation to understand current financial positions. While 30% report full confidence in their ability to see true cost-to-date positions during a live project, 55% describe moderate confidence and often require manual checks to validate committed spend.

The consequence is not just slower reporting, but delayed decision-making. Opportunities to address emerging issues such as re-sequencing work, tightening cost control or recovering value through variations can be missed because the issue is not yet visible in the numbers.

This is where a construction-specific ERP platform, connecting procurement, subcontractor management, valuations and financial reporting in one environment, changes the dynamic. Instead of rebuilding records from spreadsheets and emails, teams work from a single, connected set of approved records, where cost, value and evidence move together.

Finance teams can see live CVR positions, reflecting actual cost-to-date against delivered value, with approvals and supporting documentation attached to the job record. This strengthens reporting confidence and reduces reliance on retrospective adjustments.

Forecasting in a Moving Environment

During live construction projects, forecasting is only as strong as the records behind it.

For contractors, accurate forecasting underpins cash flow management and resource planning. For developers and housebuilders, it informs funding decisions, land strategy and build-out rates.

Yet, forecasting becomes unreliable when key elements sit outside the core workflow. Unapproved variations, delayed subcontractor applications or incomplete cost capture can all sit outside the visible position.

A project may appear to be tracking its target margin, while underlying cost or value movements remain unrecognized. When these are eventually recorded, the forecast often shifts late in the project lifecycle when recovery options are limited.

Only 13% of organizations report completed work is reflected as coded cost data in finance systems on the same day, according to data from our report.

For finance teams, this reduces confidence in reported figures. Questions start coming up including:

• Are all variations captured?
• Are subcontractor costs fully reflected?
• Are current valuations supported by invoice-ready evidence?

In a sector where margins are tight and external pressures continue to rise, the ability to base forecasts on live, connected records rather than reconstructed data is becoming critical.

Closing the Gap Between Site, Finance

Addressing the problem requires closer alignment between what happens on site and how it is recorded.

In practical terms, that means capturing cost, change and progress data at source, and ensuring it flows through commercial and finance workflows with traceable approvals attached.

A construction-specific ERP platform, connecting these workflows from back office to site and through to billing and reporting, enables that flow. This keeps systems from relying on handoffs between systems, records move together from requisition and goods received note (GRN) through to valuation, invoice and payment.

The result is not just faster reporting, but stronger control. Approved records, evidence and decisions stay connected throughout the project lifecycle, reducing the need for rekeying, reconciliation and retrospective validation.

[subhead] A Growing Priority for the Construction Sector

When systems do not reflect how large, complex construction organizations actually operate, risk increases and margin protection becomes harder.

Infrastructure schemes, large residential developments and mixed-use projects all involve multiple entities, contract forms and supply chain relationships. In that environment, control depends on how well information moves across the business.

Margin erosion rarely appears as a single event. It builds gradually in the gaps between site activity, commercial processes and financial reporting.

Closing those gaps by ensuring cost, value and evidence move together is becoming a priority for construction leaders looking to protect margin, strengthen reporting confidence and maintain control across the full project lifecycle.
