One fake invoice can wipe out a job's profit. Let's catch it before the money moves.

For contractors, builders and the trades

You're the owner or office manager who runs bids, payroll and payments. When an invoice looks off, your team at KDS is the call to make.

What could go wrong

Contractors move real money on thin margins: progress draws, supplier invoices, payroll every week. Criminals know it. They get into a supplier's or sub's email, wait for a real invoice, then send 'updated' bank details. Meanwhile the estimates, bids and job files sit on a laptop nobody's backing up... until the morning it won't start.

Ransomware can freeze the estimating computer the week a bid is due.

Here's what we do about it.

A dedicated contact who knows your systems, and managed security on every computer at the level you pick.

  • One phone call to a number you already have stops bank-change fraud.
  • Bids and job files stay safe if a laptop dies.
  • Every computer is patched and protected.

That call is the habit we help you set. Level 2 adds email security against phishing, spoofed vendors and fake invoices, and your dedicated contact is who you ask when an invoice looks off. Your team at KDS also applies the patches, and Level 3 adds cloud backup of every computer, the estimator's laptop included.

Level 1 covers patching and protection on every computer. Level 2 and Level 3 add managed detection and response.

What it costs and how to start

Three levels of protection for office desktops and field laptops, Windows or Mac, priced per computer, so you pay for exactly what you have.

The levels and prices are further down.

Three questions to answer before your next draw goes out

  1. If a supplier emailed new bank details today, who would catch it?
  2. If the estimating laptop died tonight, would Friday's bid go with it?
  3. If someone got into your email on a Friday night, how would you find out?

If the honest answer is "I'm not sure"... that's the answer.

Not sure where you stand? Let's talk.
