Vendor Management

Why vendor management is critical

The downside is priced, and it is not small. Surety industry data puts the cost of a subcontractor default at 1.5 to 3 times the original subcontract value, once completion costs, delay and re-procurement have all landed. In a recent AGC/FMI survey, 70% of general contractors reported rising subcontractor distress, with roughly half suffering project disruption from an actual default.

The macro picture explains why. Construction is persistently the highest-insolvency sector in every economy that publishes the data — in the UK, around 17–18% of all company insolvencies, with specialist trade subcontractors worst hit. This is not a bad year. It is the shape of the industry.

And the cascade risk is the lesson of the last decade’s collapses. When a major contractor fails — Carillion, ISG — owing very large sums to its supply chain, the secondary insolvencies ripple outward through everybody’s approved vendor list at once. Capacity vanishes at exactly the moment re-tendering demands it, and the firms you would have turned to are the firms that were owed the money.

The fraud angle is quietly procurement-shaped too. Corruption — kickbacks, bribes, related-party dealing — features in roughly half of construction fraud cases. Which is why a vendor master needs ownership declarations and cross-checks against your own employee records, and not merely a trade licence scanned into a folder.

The role of vendor management in performance

• Prequalification checks capacity, not just paperwork. Financials, licences, HSE history, current workload, bonding capacity — the questions that actually predict whether the work gets delivered. In the Gulf, add the regulatory layer: a valid trade licence with the correct activity codes, municipal classification grades, and ICV certificates, which carry a 14-month validity tied to audited financials. Track those expiries exactly as you track insurance, because working with a lapsed licence can invalidate the contract you are relying on.

• The loop that is almost always broken: scores feeding awards. Most contractors score vendors at closeout, if at all, file the score, and then the next tender committee never sees it. The performance system only works if the enquiry workflow surfaces prior scores and active suspensions at the moment of shortlisting — in the screen, in front of the people deciding. A rating nobody consults at award time is not a control. It is a diary.

• Distress monitoring beats annual refresh. The prequalified-then-collapsed pattern is well documented: major failures have passed framework checks weeks before their insolvency. An annual refresh cannot catch that, because the information it needs did not exist a year ago. Continuous triggers can: payment-application slowdowns, labour thinning on site, sub-tier suppliers calling you about unpaid bills, insurances lapsing, a bank declining to renew a bond. Every one of those signals already exists somewhere in your project data. The trick is having systems connected enough to read them together.

• Duplicate vendor records mask risk. “ABC Electromechanical LLC” and “ABC Electro Mech” are the same company and two records. Between them they split the performance history, dodge the suspension, understate your concentration exposure — and drive duplicate payments: recovery-audit data traces roughly 30% of duplicates to duplicate vendor records. Sometimes the second registration is innocent. Sometimes it is not. Either way, master-data hygiene is risk management wearing an admin costume.

• Blacklisting needs due process. Distinguish a time-boxed, cause-coded suspension with a review date from permanent removal. Document the cause. Ad-hoc blacklisting creates legal exposure, and it quietly shrinks the bidder pool that your pricing depends on — which means the punishment lands partly on you, some months later, in a tender you did not connect to the decision.

• Concentration is a project-level number. One MEP subcontractor carrying 40% of a project’s subcontract value — or holding five live packages across your portfolio — is an exposure that no company-level score will ever reveal. A vendor can be excellent and still be too much of your risk. Measure concentration where it actually bites: per project, and across the portfolio.

What happens without vendor discipline

Weak prequalification, so a distressed subcontractor wins on lowest price — and the price was low precisely because they were distressed. They default mid-structure. The replacement costs up to triple the money, plus months of delay, plus your own liquidated-damages exposure upstream.

Fragmented records, so a suspended vendor is re-awarded under its second spelling, by people who genuinely did not know.

No expiry tracking, so a subcontractor is on site with lapsed insurance on the day of the incident — and the uninsured claim lands on the main contractor, which is to say on you.

And scores never consulted, so the same underperformer wins again. Not because anybody defended them. Because price was the only data on the table.

How Zepth runs vendor management

One vendor master across every project: registration, prequalification documents with expiry alerts, categories and ratings, and a performance history fed by live project records — purchase orders, deliveries, inspections, NCRs, payment behaviour — rather than by recollection at closeout.

Status controls that the tendering workflow actually enforces: active, suspended, blacklisted, with cause and review date. The suspension is not a note in a file; it is a gate at shortlisting.

And concentration and exposure visible per vendor across the portfolio — because the question that matters is rarely “is this vendor good?” It is “how much of us are they carrying?”
