The Payment Trail That Holds Up in a Dispute

The Problem

Payment disputes in UK construction are costly, time-consuming, and increasingly common. When they arise — whether through adjudication, mediation, or litigation — the outcome often turns less on the merits of the case than on the quality of the documentation.

Most teams discover this too late. The dispute arrives. The adjudicator requests the payment record. And the evidence is spread across spreadsheets, email attachments, and shared drive folders that haven't been consistently maintained.

The result is a weakened position — not because you were wrong, but because you can't prove you were right.

What Claims Defence Requires

A credible payment claim or defence rests on a clear, chronological record of five things:

1. What the contractor applied for — the payment application for each interim period, with supporting breakdown
2. What was certified — the payment certificate, issued on time, showing the assessed amount
3. What was withheld — any pay less notice, issued before the contractual deadline, with the reason for withholding
4. What was paid — the actual payment, on what date, against which certificate
5. What the variation position was — instructed variations, their agreed values, and their inclusion or exclusion from the interim assessment

In a well-managed project, this record exists as a natural byproduct of the commercial management process. In a spreadsheet-managed project, it has to be reconstructed — and reconstructed evidence is always vulnerable to challenge.

How FlowMetrics Supports Claims Defence

Contract-Aligned Payment Records

FlowMetrics tracks every interim valuation cycle in a structured, timestamped record. Each period shows: application received, assessment made, certificate issued, pay less notice (if issued), payment received, and any outstanding balance.

This is not a report generated for the dispute. It is the living record of how the project was managed.

Variation and Change Order Tracking

Every variation instructed on the project is logged against its contract mechanism (AI under JCT, PMI under NEC), valued, and linked to its assessment status. When a contractor claims for unvalued variations, FlowMetrics shows what was instructed, what was assessed, and what the current agreement position is.

Pay Less Notice Management

FlowMetrics tracks the payment notice deadlines for each interim period and alerts the team before they pass. Every pay less notice issued is stored within the platform, timestamped to the date and time of issue, with the stated reason.

This eliminates the risk of a missed deadline — and creates a contemporaneous record that is far harder to challenge than a document retrieved from an email archive.

Withholding Documentation

When a withholding is applied, FlowMetrics records the reason, the amount, and the period to which it relates. This documentation forms the basis of your response if the withholding is challenged.

Exportable Evidence Package

When a dispute is notified, FlowMetrics generates a complete payment history package: all interim certifications, all pay less notices, all payment records, and the full variation position — ready to be handed to your legal team or included in an adjudication referral.

Who Uses FlowMetrics for Claims Defence

Cost consultants and QS firms — maintaining an independent payment record on behalf of the employer, building the audit trail that supports their client's position in any future dispute

Employers' agents — administering the contract and maintaining the official payment record for the developer, with full documentation of every certificate and withholding

Property developers — tracking payments across one or more live build contracts, with confidence that the payment record is complete and defensible

Main contractors — maintaining their own payment record alongside the employer's assessment, identifying discrepancies early, and building the documentation for a payment claim if needed

The Cost of Not Having This

In a payment adjudication, the referral period is 28 days. That is 28 days to assemble and present the payment record for what might be an 18-month project.

In a spreadsheet environment, this means 28 days of frantic document recovery, version reconciliation, and evidence assembly — while also managing a live project and preparing a substantive legal response.

In FlowMetrics, it means exporting the payment history and handing it to your legal team on day one.

The platform cost of FlowMetrics is insignificant compared to the cost of a single adjudication. The document preparation cost alone — in management time and professional fees — will exceed an annual subscription.
