Why contractors call us

Five things that go sideways in a growing trade business — and how we fix them.

If any of these are on your mind right now, we have probably already built the playbook for it.

1

Dispatch goes down and the trucks stop ServiceTitan, Housecall Pro, or your dispatch board freezes and the coordinator is calling the carrier from a parking lot. We monitor the integrations and connectivity proactively.
2

Field tablets and phones managed by hope Tablets get lost, dropped, handed to a subcontractor, sometimes walked off the job. We deploy MDM so a missing device is not a data exposure or a customer-PII problem.
3

Onboarding and offboarding done by group text A foreman leaves and their email is active for six months. A new hire spends three days waiting for shared-drive access. We make hire-day and last-day a documented process: account, MFA, M365 license, and shared access closed out the same day.
4

GC prequal asks for security documentation you do not have The bigger the GC, the longer the questionnaire. We maintain MFA enforcement, EDR, backup records, and written policies so a prequal lands on Tuesday and gets answered by Wednesday.
5

Phishing emails trying to change vendor payment instructions Construction is one of the most-targeted industries for business email compromise. We deploy email security, enforce MFA, train staff on payment-change scams, and lock M365 down the way an attacker tests it — not the way the defaults ship.

One honest note before you call.

If you already have a full-time IT person on staff, we are probably not the right fit and we will say so on the first call — we will not waste your time selling around it. If you have nothing in place today, or you have a part-time relative handling it, that is exactly who we are built for.
