Commercial protection
for UK contractors
for UK contractors
ShadowQS reads your project emails to surface payment risks, undocumented variations and overdue retention — before they become disputes.
Early warning, not late surprises
Variations, payment delays and verbal instructions flagged the day they appear — not weeks later when the window has closed.
Retention you can actually track
See exactly what's held, what's overdue, and when it should be released —
across every live project in one view.
Read-only. UK-hosted. Revocable.
Project emails only — personal, HR and finance threads filtered out. We never send or modify. GDPR-aligned. Disconnect anytime.
"We had a variation confirmed on site but the main contractor never copied us in commercially.
ShadowQS flagged the instruction in our emails and we got it valued and agreed before the final account closed."
