Construction & Job Site Management
Payments, permits, and communication for job sites in cellular dead zones
The Problem
Construction projects frequently operate in areas with poor or no cellular coverage — new developments in rural areas, infrastructure projects along highways, remote site preparation, and vertical construction where building materials block signals. Subcontractors need to submit invoices, crews need to report time, material deliveries need to be confirmed, and safety incidents need to be communicated in real time. When the job site is in a dead zone, all of this operational communication waits until someone drives to cell coverage — introducing delays that cascade through the project timeline. Payment delays are particularly acute: subcontractors who can't submit invoices from the job site face 60-90 day payment cycles instead of 30 days, creating cash flow pressure that small contractors absorb disproportionately. Safety reporting delays in dead zones can result in OSHA compliance issues and, more importantly, delayed emergency response when injuries occur.
How M6:6 Solves It
M6:6 turns any smartphone on the job site into a satellite-connected business terminal. The Mite POS processes subcontractor payments, material purchase confirmations, and equipment rental charges without internet connectivity. The SMS bridge enables real-time communication between the job site, the office, and subcontractors — schedule changes, material delivery coordination, and inspection scheduling all happen in real time regardless of cellular coverage. P139 Safety provides automatic fall detection, no-movement alerts, and emergency messaging with GPS coordinates — critical for construction sites where falls, equipment accidents, and medical emergencies occur. Mustard Chain provides tamper-evident documentation of material deliveries, inspection completions, and safety incidents — creating a cryptographically verified project record that supports dispute resolution and compliance auditing.

Frequently Asked Questions
Can subcontractors use their own phones?
Yes. Subcontractors can submit invoices, confirm material deliveries, and report time through a web interface served from the site supervisor's M6:6 device — no app installation required. For payment receipt, subcontractors receive confirmation via SMS when they return to cell coverage.
How does this handle OSHA safety reporting requirements?
Mustard Chain creates tamper-evident records of all safety incidents, inspections, and training completions with timestamps and GPS coordinates. These records are cryptographically verifiable and resistant to retroactive modification, providing strong documentation for OSHA compliance. Reports can be transmitted in real time via satellite, eliminating the communication delay that often complicates incident reporting in dead zones.
What's the cost for a typical construction site?
One satellite modem accessory ($300-500) covers an entire job site. M6:6 has no monthly subscription. Satellite message costs are $0.01-0.15 per message, and payment processing is 2.5% per transaction. For a typical site with 20 daily operational messages and 5 weekly payment transactions, the total cost is under $100/month.
