The money moves by email. So do the thieves.
Your office is wherever the job is. Plans live on laptops and tablets, bids move by email, crews coordinate by phone — and the money moves by wire, which is exactly where construction firms get robbed. We keep builders and contractors connected, organized, and protected, from the main office to the job-site trailer.
Six bottlenecks we walk into, over and over
The “updated wiring instructions” email
The construction-specific scam works like this: someone compromises an email account — yours, a vendor’s, a title company’s — watches the payment threads, then sends a convincing change of wiring instructions at exactly the right moment. The money goes, and it doesn’t come back. There is no version of this where the bank undoes it next week.
Bid day, wrong drawing set
Drawings, specs, submittals, change orders — and three versions of each, in four places, with the crew building off the wrong one and the estimator pricing off another. The version problem isn’t a software problem. It’s that nobody ever made one managed home for the current set.
The trailer with a hotspot and a prayer
The job-site trailer runs on a personal phone hotspot, the superintendent pulls plans from the truck, and sync fails quietly until the day the plan set on site is two revisions old. Connectivity improvised per job means every job starts with the same fight.
The bid package lives on one laptop
Estimating files, takeoff history, the accounting system — on the one machine that also goes home in the owner’s truck. It works, right up until that machine dies during a deadline week, and the backup turns out to be a hope instead of a restore.
Subs and ex-employees still inside the files
Finished subs, departed estimators, last year’s office help — still holding logins to email, file shares, and the plan room. Crews change constantly in this business; access almost never changes with them.
The owner is the IT department
Most contractors’ IT grows the way the company did — one piece at a time: a second entity here, a new office there, project files split between the office server, the owner’s laptop, and somebody’s personal cloud account. It works until a bid goes missing, a payment gets diverted, or the one computer with everything on it dies.
One phone call stops the most expensive scam in construction
The technical half matters — MFA on every mailbox, email authentication (SPF, DKIM, DMARC) so your domain can’t be spoofed, monitoring that flags a mailbox being quietly forwarded. But the habit that breaks the scam completely is the payment call-back drill: any change to payment instructions gets verified by phone, on a number already on file — never a number from the email asking for the change. We put the technical half in place, verify it, and help you make the drill a firm rule nobody gets in trouble for following.
Office, trailer, and field — run as one system
Estimating and accounting run the business side of every job. We keep the workstations, network, and backups behind them maintained and monitored — including multi-entity setups as firms grow — and coordinate with your software vendors when an issue is on their side.
Job-site connectivity and field devices get set up on purpose: trailers connected, crews’ phones and tablets enrolled, secured, and accounted for — so a lost phone is a replacement, not a data problem.
Texas SB 2610 (Business & Commerce Code Chapter 542, in force since September 1, 2025) covers Texas businesses under 250 employees holding sensitive personal information — payroll and client data count. A documented, framework-based program is the safe harbor if a breach ever happens.
What “organized” looks like
- One managed home for plans and bids — the current set is the one everyone sees
- Estimating and accounting backed up, with restore tests on the calendar
- MFA on every mailbox; SPF, DKIM, and DMARC verified on your domain
- The payment call-back drill written down and followed every time
- Access created and closed as crews and subs change
- Field devices enrolled, secured, and accounted for
That’s the standard our managed plans are built to — and the checklist below shows you where your firm stands against it.
Grade your own firm in about ten minutes.
A working checklist, not a brochure — fronted by the payment call-back drill, the one habit that stops diversion fraud cold, then the job-site and office checks we run on site: trailer connectivity, plan control, and backups that have actually been restored.
- The payment call-back drill, written out step by step
- Mailbox & domain checks that stop impersonation (MFA, SPF, DKIM, DMARC)
- Job-site checks: trailer connectivity, current plan set, field-device control
The $495 Network & Risk Assessment
We don’t guess about a network we haven’t looked at, and we don’t do free audits that are really sales calls. For a fixed $495, we examine your network, email security, backups, and who has access to what — and deliver a written findings report: what’s solid, what’s exposed, and what to fix first.
The report is yours either way — hand it to whoever you choose. If you sign a managed agreement within 30 days, the full $495 is credited toward your onboarding, so the assessment costs you nothing.
What the report covers
- Email security — SPF, DKIM, DMARC, and MFA coverage
- Endpoint protection status on every computer
- Backup coverage — and when a restore was last tested
- Access review — including accounts of people who’ve left
- A prioritized fix list in plain business language
Sales line: (361) 315-0017, Mon–Fri 8am–5pm CT.
Signs your firm has outgrown “call a guy when it breaks”
- Payment instructions move by email with no verification step — and no technical controls behind them
- Nobody’s certain which drawing set is current, or where it lives
- Project files and bids sit on one machine, and the backup has never been test-restored
- Ex-employees and finished subs still have access to email or files
- Multiple entities or offices, each improvising its own IT
- The owner or office manager has become the IT department

Frequently asked questions
How does payment-diversion fraud actually happen — and what stops it?
An attacker gets into an email account (often with a phished password), watches real payment conversations, then sends a believable message changing the wiring instructions. What stops it: MFA so a stolen password isn’t enough, email authentication (SPF/DKIM/DMARC) so your domain can’t be impersonated, mailbox monitoring for hidden forwarding rules, and a firm habit of verifying any payment change by phone. We put the technical half in place and verify it.
Can you support our job sites and field crews?
Yes — trailer connectivity, field laptops, phones, and tablets are part of the environment we set up and secure. Most support is handled remotely; on-site help is available across the Coastal Bend.
We run multiple entities / offices. Is that a problem?
No — it’s common as firms grow, and it’s usually where the file and access chaos starts. We organize accounts, files, and backups across entities so each company’s data stays straight and protected.
Do you work with our estimating / accounting software?
We support the environment those systems run in — workstations, network, backups, and access — and coordinate with your software vendors when an issue is inside their application.
What does the $495 Network & Risk Assessment involve?
We review your network, email security, backups, and account access, then deliver a written findings report with a prioritized fix list — yours to keep either way. For contractors it includes a specific look at your payment-email exposure. Sign a managed agreement within 30 days and the full $495 is credited toward onboarding. Call (361) 315-0017 to schedule.
What is the payment call-back drill?
It’s a standing firm rule: whenever payment instructions change — new bank, new account, new wiring details, by email or message — the person paying stops and verifies by phone, calling a number already on file for that vendor or client, never a number supplied in the message requesting the change. It takes two minutes, it works even when the request came from a genuinely compromised mailbox, and nobody at the firm ever gets in trouble for doing it. The checklist on this page writes the drill out step by step.
