The unrecorded verbal
Foreman gets told “crack on,” but nothing is logged. By the time QS asks, the labour and materials are already sunk and the instruction can’t be priced properly.

Meta description: Capture WhatsApp photos and voice notes, generate CVIs and variation claims fast, and stay JCT/NEC compliant with Varify.
Variation software for UK subcontractors
Stop leaking margin on variations.
Foremen send WhatsApp notes. Varify turns them into priced, contract-compliant variation claims in minutes.
Built for JCT & NEC sub-contracts. Works in WhatsApp.
Profit leakage
Variations aren’t lost on site — they’re lost in the admin gap.
Verbal instructions, late notices, and end-of-job arguments quietly strip margin. The damage is commercial, measurable, and avoidable.
Most subcontractors leak 1–3% of turnover.
On a 5% margin, that’s up to half your profit, gone.
The missed notice window
NEC and JCT notice periods are tight. Miss the window and the claim is weakened or dead — even when the work is valid and completed.
The “sort it at the end” trap
Final account turns into a fight. Evidence is thin, rates are argued down, and cash is delayed. Margin evaporates when the leverage is gone.
Protect margin with real-time, contract-ready evidence
Varify captures the instruction at source, timestamps it, and turns it into a compliant VI/CVI before the notice clock runs out. You recover profit early, reduce final account pain, and keep your margin where it belongs.
Stop leakage: every variation logged, priced, and issued before it’s forgotten.
Recover profit sooner: stronger interim apps reduce the end-of-job squeeze.
Defend margin: notices issued on time, evidence aligned to JCT/NEC rates.

ROI Snapshot
The maths your finance director will love
A £5M drylining subcontractor on 5% margin typically leaks ~£75,000 a year. Varify recovers a conservative £45,000, the profit equivalent of winning £900,000 of new turnover, for a tool costing around £8k.
