No change to your current process
Nothing to migrate · nothing to learn · your team keeps working exactly as they do today.
An email lands: "Morning mate — client wants the extra ductwork doing on level 3, crack on and we'll sort the paperwork after." Sounds friendly. It's an unconfirmed verbal instruction — the kind that gets denied at the final account. Shield read it, flagged it and told you why — before you'd replied.
Every email, WhatsApp message and site record, the moment it arrives. Not summarised — read line by line against every commercial risk trigger a QS would recognise: variations, time-bars, pay-when-paid, contra-charges, EOT events, tone shifts.
The risky sentence highlighted in the original message. The clause it touches, cited. The severity, explained. You're never asked to trust a score — you're shown the evidence.
A drafted reply is waiting — clause-cited, protective, ready to review and send. The confirmation you'd write if a QS read every message over your shoulder, on every job at once.
No other tool in construction reads your communications as they happen. Everything else is a filing cabinet. This is a QS at the letterbox.
An AI that reads your inbox for danger, not a summary — trained on JCT and NEC subcontract language. See how the engine reads →
Most directors find out which job is bleeding money at the final account. Shield ranks every live project by money at risk — the riskiest job is the first thing you see on Monday. And it shows the risk your managers are carrying, so you can back them while it's still a conversation, not a write-off.
A project that's gone quiet gets flagged too — silent drawing revisions and unanswered notices are how disputes start. The weekly report tells you which jobs need a phone call.
Click any risk on the board and you're reading the exact email that raised it, with the risky sentences highlighted and the suggested reply alongside.
When a main contractor leans on your site manager, you'll see it in the traffic — and your manager gets a clause-cited reply to send instead of a problem to carry alone.
Everyone stores emails. Procore stores them. Aconex stores them. Shield is the only one reading every line as it arrives and saying "this is a verbal instruction — you're exposed; here's the reply you should send." By the time you need the evidence, it's already organised.
One forwarding address per project. Set a Gmail filter or Outlook rule once and every email from your main contractor arrives in Shield automatically.
Every message read the moment it lands — money, time, action-needed and safe, sorted as it arrives. Every trigger a QS would recognise, none of them missed.
One click and you get a tamper-proof PDF your solicitor can rely on — cover page, evidence timeline and integrity statement. The thing your solicitor actually wants, without the days of inbox archaeology.
Real screens from the product — not mock-ups. The full walkthrough is on the features page.

Chasing by phone gets promises. Shield attaches the statutory wording a QS recognises on sight: 8% interest above the Bank of England base rate plus fixed recovery costs — your automatic right under the Late Payment of Commercial Debts (Interest) Act 1998. No contract clause needed. Your evidence trail goes with it.
Every overdue invoice states your legal right to interest and recovery costs, plainly. Not a threat — a fact, backed by an Act of Parliament.
The invoice defence pack links the payment application to the instructions, variations and milestones behind it. "We never agreed that" stops working when the agreement is attached.
Every invoice tracked against its payment terms on the same board as your risk. You see "approaching overdue" before your cash flow does.
Every project ships with the full toolkit — contract scanner to board reports, eight tools in one workspace. See the toolkit →
Frankie Rayner runs OD Restoration, a specialist building contractor. Shield exists because he spent years watching good firms — his own included — lose money they'd already earned: the verbal instruction that got denied, the variation that was never confirmed, the contra-charge that landed six months after the job. Every trigger in Shield's AI comes from something that actually happens on site.
"I didn't build Shield to sell software. I built it because I needed it."
