One fake invoice can wipe out a job’s profit.
Payment fraud is the #1 cyber threat to contractors: spoofed supplier invoices, hijacked payment instructions, and fake GC emails. Meanwhile GCs and insurers increasingly require proof of security before you can bid or bind coverage.
What's actually at risk
Supplier invoice fraud
Attackers watch a real email thread, then send a "updated bank details" note from a lookalike domain. The money leaves and doesn’t come back.
GCs now require security
Bigger general contractors are pushing cyber requirements down to subs: no proof, no bid. It’s becoming as standard as insurance certs.
