Sound familiar?

The margin killers every specialist sub knows.

M&E subcontractors typically lose 15–22% of potential profit to admin gaps, unclaimed VOs and late payment chasing.

Laggers on the wrong floor — again
Engineers turn up to the wrong zone, WhatsApp 400 messages deep, half day lost. No written record for delay costs.
✓ Contraq Diary assigns to zones, logs restrictions, builds the paper trail.
Payment applications going nowhere
ValApp 4 submitted 6 weeks ago, no pay less notice, 5% retention from three jobs unclaimed.
✓ Tracks every application, flags missing notices, chases retention dates.
Quotes buried and spec revisions missed
Quote based on NBS Rev B, they issued Rev D, you find out on site and eat the cost.
✓ Links quotes to spec revisions, flags superseded drawings, timestamped records.
Knauf short-delivered and nobody told you
3 pallets instead of 5, lagger runs out Monday morning, Mace charges you for the delay.
✓ PO register logs deliveries against orders, flags shortfalls before they hit site.
VOs going uninvoiced until it's too late
Spec changed from Class O to Class 1 mid-job, no VO raised, 22% margin job finishes at 11%.
✓ Journal logs every instruction, one-tap VO drafting before the right to vary expires.
CSCS card expired — turned away at the gate
Best lagger turned away at 7am, Gold Card expired last Tuesday. Day's production lost.
✓ Tracks every cert with 30-day and 7-day expiry warnings across your workforce.
