Proof. Deadline. Paid.
1 in 6 UK insolvencies is a construction firm. Most were owed money they couldn't prove.
SIGNOFF closes the evidence gap before it becomes a payment gap.

Why SIGNOFF?
Payment disputes rarely start at payment. They start when site work is not properly recorded.
Evidence lives in too many places
Photos on phones, dockets in vans, instructions on WhatsApp. The information exists — it just is not linked to the job it belongs to.
Verbal instructions are easy to lose
Extra work gets agreed and done immediately. Without a captured record, questions arise later — not from bad intent, but because no one wrote it down.
Approvals involve different people
The person who saw the work and the person who approves payment are often not the same. Both need different information, at different times.
Documents expire without warning
Insurance certificates, CSCS cards, plant inspections — all with different renewal dates. One expiry can hold up an operative, a machine, or a whole job.
What SIGNOFF Does
A complete evidence-to-approval toolkit built for subcontractors.
Evidence Pack Builder
Upload photos, dockets, timesheets, and instructions into a single structured pack linked to the variation.
Variation Instruction Trail
Record who instructed the work, when, and how — even if it was verbal. Create an auditable chain.
Shareable Review Link
Generate a secure link for the Main Contractor to review. No login or account required.
Two-Step Approval
Separate site verification from commercial approval so everyone knows exactly where the claim stands.
Status Tracking
See in real time when your pack is viewed, verified, and approved. No more chasing.
AI Evidence Completeness Checker
Our AI reviews your pack before you share it and flags anything missing — photos, timestamps, signatures.
AI Auto-Summary
Automatically generates a plain-English summary of the variation and evidence for faster reviewer decisions.
Audit Trail PDF Export
Download a timestamped, tamper-evident PDF of the complete evidence pack and approval history.
Document Expiry Alerts

The “Two Approval” Clarity
By separating Site Reality from Commercial Entitlement, SIGNOFF removes the “I didn't know work was done” excuse that delays payments.

Variation: Additional Drainage — Block C
“I spoke to construction professionals across the UK before building anything. The same problem came up every time — work done, proof missing, payment delayed. SIGNOFF exists to close that gap.”

Never Get Caught by an Expired Document
CSCS cards, insurance certificates, and plant inspection records all have expiry dates. One lapsed document can delay an entire claim.
CSCS Cards
Track operative competency cards and get alerts before they expire, so no one is turned away from site.
Insurance Certificates
Monitor public liability, employer’s liability, and professional indemnity renewal dates in one place.
Plant Inspections
Keep plant and equipment inspection records current. One lapsed certificate can ground an entire machine.
