What are the early warning signs of subcontractor default?
Six of them, and none requires a forensic accountant. Labour thinning on site. Sub-tier suppliers calling you about bills your subcontractor has not paid. Requests for advance payment. Insurances lapsing. Quality and safety metrics sliding. And a bank declining to renew a bond. Surety data prices the outcome at 1.5 to 3 times the original subcontract value — so the signals are very much cheaper than the event.
The tell that arrives first
It is usually the phone call from somebody you have no contract with. A sub-tier supplier, ringing the main contractor because your subcontractor has not paid them and they have worked out who actually has the money.
That call means the subcontractor is already choosing which bills to pay. By the time they are choosing, the decision about your project has usually already been made — they simply have not told you yet.
The rest of the pattern
Labour deployment thinning while the programme still demands it. Requests for advance payment, or for payment terms to be accelerated. Insurances quietly lapsing and not being renewed. Quality and safety metrics sliding, because a firm under financial stress cuts supervision before it cuts anything visible.
And the one that should stop a commercial meeting dead: a bank declining to renew a bond. The bank has seen the accounts. You have not.
Why watching is rational
A subcontractor default typically costs 1.5 to 3 times the original subcontract value — retendering, remobilisation, programme impact, the premium you pay whoever picks up an abandoned scope mid-way.
Detection sixty days earlier changes what you can do about it: a managed handover instead of a walk-off, a negotiated exit instead of a termination. Which is the whole argument for having these signals in a system that correlates them, rather than scattered across the memories of the four people who each saw one of them.
