Late payments and the fragile logistics base

Across the UK’s logistics base, cash rarely moves with the same urgency as goods. Pallets can be delivered overnight, urgent components can be moved across borders under pressure, and a haulier can absorb a late change to a delivery slot, yet payment for completed work can still sit unresolved weeks after the service has been delivered.

That gap between operational speed and financial delay is now moving into harder regulatory territory. The Small Business Protections Bill, formally known as the Commercial Payments Bill, was introduced to Parliament on 19 May 2026 with proposals for a 60-day cap on payment terms for large companies paying smaller suppliers, mandatory interest on late payments at 8% above the Bank of England base rate, and stronger powers for the Small Business Commissioner to investigate poor payment practices, adjudicate disputes, and fine persistent late payers.

Overdue invoices are not simply an accounts payable nuisance for companies operating inside supply chains. They sit beneath the capacity of regional hauliers, specialist warehouse operators, customs intermediaries, fulfilment providers, maintenance contractors, and subcontracted delivery businesses. These companies are expected to absorb changes in fuel, labour, insurance, rent, compliance, and vehicle costs, while still providing the flexibility larger customers increasingly require.

Government commissioned research published by the Office of the Small Business Commissioner estimates that late payments cost the UK economy almost £11bn each year and contribute to 14,000 business closures annually, equivalent to 38 businesses every day. More than 1.5m businesses, or 28% of UK businesses, are affected each year, while £26bn is owed in late payments at any given time.

Inside logistics networks, those figures become decisions that rarely appear on a customer dashboard. A delayed payment can push back a maintenance decision, restrict agency labour cover, slow investment in routing software, or leave an operator carrying higher costs until contract renewal. Where margins are thin and cash conversion is slow, the supplier meeting today’s service levels may still be losing the financial room needed to remain dependable.

Payment terms enter the resilience debate

Supply chain resilience is often discussed through alternative suppliers, buffer stock, transport visibility, and regional sourcing. Payment behaviour belongs in the same conversation, although it has usually sat with finance teams rather than operations.

When a buyer asks a logistics partner for contingency capacity, it is asking that business to hold headroom. Extra vehicles, trained staff, usable space, system capacity, and trusted subcontractor relationships all carry cost before they are called upon. If the same buyer then extends payment terms, raises invoice queries late, or leaves smaller suppliers to chase money for completed work, the requested resilience is being carried by the supplier’s balance sheet.

The research behind the late payment reforms found that 22% of surveyed businesses spent staff time chasing overdue invoices, with affected businesses losing an average of 86 hours a year to the task. Across the economy, that equates to 133m staff hours. For a smaller logistics business, those hours are not surplus administration. They are taken from planning, customer service, compliance, recruitment, and operational improvement.

Payment behaviour can also reduce supplier choice before a sourcing exercise begins. The Government’s consultation response found that 15% of surveyed businesses had avoided working with specific customers because of their payment practices. In logistics, the loss of good suppliers often appears gradually, through fewer regional specialists willing to bid, a thinner carrier base, less appetite for tailored service levels, or higher prices from operators that have learned to price payment risk into the contract.

A procurement process that treats extended terms as a commercial saving can miss the fragility it creates. The buyer may gain a short term cash advantage, but the supply base responds over time. Some suppliers walk away, while others raise prices or limit the flexibility they are willing to provide. Those that remain may have less room to invest in the systems, equipment, and people that customers expect them to have available when disruption arrives.

The Government’s consultation response links late payment to weaker cashflow, pressure on companies’ ability to pay staff and suppliers, and reduced investment in technology, innovation, and training. That connection lands heavily in a market being asked to modernise quickly. Logistics operators cannot improve digital integration, emissions reporting, fleet performance, and labour productivity while overdue invoices remove the cash needed to make those changes.

A governance issue, not a back office problem

Under the proposed reforms, persistently late paying large companies would face greater pressure to explain their performance. The Small Business Commissioner says the Bill includes a requirement for boards or audit committees of any persistently late paying large company to publish commentary on why payment performance is poor and what actions are being taken to fix it.

That change could alter internal ownership of supplier payment. Once payment performance sits in board commentary, it becomes harder to leave the issue buried in accounts payable workflows, disputed invoice queues, or procurement terms that look efficient only from one side of the relationship.

Procurement leaders already assess supplier risk through credit checks, insurance certificates, service history, and financial statements. The weaker point is often the buyer’s own behaviour. A logistics partner under cash pressure may still meet today’s delivery target, but its ability to invest for tomorrow falls when working capital is repeatedly trapped in overdue invoices.

Prompt payment does not remove cost inflation, driver shortages, property constraints, or border friction. It does, however, improve the chances that smaller providers can retain staff, service vehicles, upgrade systems, meet compliance requirements, and remain available when customers need additional capacity. In a market where resilience is routinely demanded from the supply base, payment discipline is one of the least complicated ways to protect it.

The Bill will not remove every payment dispute. Some invoices are genuinely contested, some contracts are poorly written, and smaller companies also need strong billing discipline of their own. Even so, late payment is moving into the same territory as supply continuity, governance, and responsible procurement.

In a supply chain still dealing with volatile costs, shifting trade conditions, and pressure for faster delivery, using smaller suppliers as a financial shock absorber looks increasingly dated. Resilience cannot be demanded indefinitely from companies being paid late for work already completed. A supply chain that wants dependable capacity has to fund the businesses providing it.
