The Problem

Sound familiar?

Every subcontractor knows the feeling. You do the extra work. You forget to log it. The invoice goes out short.

01

Forgotten variations

Site manager asks for something extra. You do it on the spot. By the time you're home writing invoices, it's gone from your head.

02

Evening admin nightmare

Two or three hours every evening on paperwork. Invoices, daywork sheets, purchase orders — built from scratch after a full day's work.

03

Material order chaos

Workers ask for materials on site, you say you'll sort it, and half the time it slips through. Job stops. Everyone waits. You lose money.

How It Works

Simple as sending a text

No app to learn. No forms to fill in. Just WhatsApp — the tool you already use every day on site.

Step 01
📱

Text or voice note

Send a message to SubSync on WhatsApp. Speak naturally — exactly like you'd text a mate on site.

Step 02
🧠

AI understands it

SubSync classifies your message — variation, daywork, material order — and saves it tagged to the right site.

Step 03
📄

Documents generated

Say "generate variations for Site X." Branded PDFs land in your WhatsApp in seconds — ready to send.

Step 04
✉️

Send to client

Review on your dashboard, hit send, and the PDF goes straight to your client. Done in under a minute.

"I used to spend three hours every Sunday doing paperwork. Now it takes ten minutes on the dashboard. The lads just WhatsApp everything as it happens."
