The problem with construction SMS
Personal phones, group chats, and email chains are not a reliable project record. By the time you need them, they're missing, scattered, or hard to retrieve, verify or rely on.
"I never received that instruction."
You gave a direction to proceed by text from your personal phone. No central timestamp. No project context. No reliable record. Now a $220,000 variation claim is riding on whether it happened.
EOT time-barred. Again.
Your subcontractor's 28-day window closed. They didn't notice. You didn't notice. The contract is clear. That delay is now on them — except your insurer wants proof you notified them properly.
Discovery: 4,000 unorganised messages.
Claims review next Tuesday. Your solicitor needs every relevant SMS from the last 18 months. Sorted by contract. Retrievable. Organised. Defensible. Good luck.
Every feature built for contract-critical messaging
Not a generic SMS tool with tags bolted on. Purpose-built for construction contract administration from the ground up.
Notice Classification
23 construction-specific categories. Formal notices, SOPA statutory, operational instructions — every message classified at send time.
Contract Linking
Link each message to a project and contract. Clause references, counterparty details, and contract numbers travel with every SMS.
Overdue Notice Alerts
Response deadlines calculated automatically. Dashboard warnings when notice periods expire with no reply recorded.
PDF Evidence Pack
One-click export of all project SMS as a verified PDF evidence report. SHA-256 integrity hash on the cover page. SOPA pack variant available for claims review.
Immutable Timestamps
ISO 8601 sent timestamps stored server-side. Carrier message IDs preserved. Records cannot be edited after send.
Team Roles
Owner, Contract Administrator, Site Team, Legal. Control who can send formal notices. Full audit trail of who sent what.
Notice Chains
Show Cause → Response, Payment Claim → Payment Schedule. Parent-child notice relationships tracked automatically.
Black Box Audit Trail
Every message is permanently logged with delivery status, sender role, recipient role, and classification decision. Always on.
SECURITY OF PAYMENT
SOPA deadlines don't move.
Under the Security of Payment Act, payment claims, schedules, and adjudication notices must be served within strict timeframes. Miss a window and your right to claim lapses — sometimes permanently.
SMSuni's SOPA Pack export collects every payment claim, payment schedule, notice of dispute, and suspension notice for a project into a single SHA-256 verified PDF — organised for rapid review and submission preparation.
Get SOPA-readyACMA COMPLIANCE · JULY 2026
New SMS sender ID rules are coming.
ACMA's new SMS Sender ID Register takes effect July 2026. Businesses sending commercial SMS from personal phone numbers or unregistered sender IDs will face increased deliverability problems and potential compliance exposure.
SMSuni sends through the Telnyx carrier network with registered Australian sender IDs. All messages travel through compliant pathways — with full audit trails to document delivery and message history.

What construction teams say
“We used to manage all our site instructions over personal phones. SMSuni gave us a proper record for the first time. When the dispute came up, we had everything.”
Project Manager
Commercial Builder, Queensland
“The SOPA pack export alone is worth it. I used to spend hours pulling messages out of three different phones before a claims review.”
Contract Administrator
Civil Contractor, NSW
“Overdue notice alerts saved us from missing a show cause response. That could have been a termination.”
