Ledger
Commercial assurance for variations, delays, and disputes.

The problem
The Friday Afternoon Phenomenon
It's 4pm Friday. The main contractor's site manager faces a blocked critical path. He turns to your foreman: "Move that containment so the ductwork fits. We'll sort the paperwork next week."
Your foreman faces an impossible choice. Demand a formal instruction and risk being labelled "obstructive." Proceed without written confirmation and create commercial exposure.
The work gets done. The paperwork never materialises. Three months later, when the QS reviews the final account, there's no evidence—and you absorb the loss.
Ledger closes this gap by making contemporaneous evidence the default, not an afterthought.

How it works
Three steps to protected revenue.
Capture
Foremen photograph and log work on site—even offline. Timestamps and quantities are captured alongside the record for clear context.
Verify
Supervisors approve via a simple link—no app install. Digital signature capture with timestamps and an audit trail for commercial clarity.
Protect
Office teams bundle approved records, apply rates, and generate dispute-ready documentation with full audit trails.
Built for UK construction
Financial Firewall
Field captures quantities. Office controls valuation. Keeps evidence capture and commercial assessment clearly separated.
Offline-first
Works in basements and tunnels. Syncs automatically when connectivity returns.
Audit trail
Key actions timestamped and logged to support commercial review and dispute resolution.
Revenue risk calculator
Calculate how much revenue is exposed when variations, delays, and disputes are not fully substantiated.
This is an estimator to help you sanity-check impact — it is not a quote or a promise of savings.

Ledger helps preserve this value when disputes arise.

What is Ledger today?
Ledger is an early-access workflow we are validating with UK construction teams. It focuses on contemporaneous evidence capture and commercial approvals—not a fully self-serve product yet.
Who is it for?
Subcontractors and commercial teams dealing with variations, delays, and final account disagreements—especially where evidence is fragmented between site and the office.
Does it replace daily site records or timesheets?
No. Ledger is positioned for commercial certainty when it matters (instructions, valuations, disputes). It is not intended to replace your operational diary, programme, or payroll tooling.
What happens after I join the waitlist?
You will be asked a few questions and we may follow up to understand your workflow. Early access is limited while we iterate, and we will be clear about what is (and is not) included.
