The problem

Margin doesn’t vanish. It’s disputed away.

The variation nobody wrote down. The notice that went in late. The proof that isn’t there.

How it works

Read. Register.
Review. Report.

One subcontract, from the first read to the finished pack.

  1. Read

    It reads all sixty pages, and the schedule of amendments behind them.

  2. Register

    Every term that decides money, quoted and placed.

  3. Review

    Anything uncertain is held back.

  4. Report

    The file is ready for the final account.

  • The subcontract
  • Z-clauses
  • Particular Conditions
  • Schedules of amendments
  • Scanned PDFs

It reads the subcontract and every amendment behind it.

The subcontract as it was issued, however long it runs, together with whatever the other side attached at the back: Z-clauses, Particular Conditions, the lot. Scanned copies are read too.

Notice / time-bar …notify within 8 weeks… 61.3 · p.22 FLAGGED
Retention 3%, half released at completion… X16 · p.18 CITED

Each term is quoted word for word and cited to its clause and page.

It pulls out payment, retention, notices, obligations, evidence and risk. Each one is quoted word for word and cited to its clause and page, then rated, so the dangerous terms surface first instead of sitting unread on page fifty-one.

Derived and date-dependent items are held before they enter the register.

If the words cannot be found in the document, the item does not go in the register. Anything derived, date dependent or unusual is held back rather than assumed; nothing enters the register by guesswork.

Word and Excel, stamped DRAFT. Your team finishes it.

One click turns the finished register into a branded pack: an editable Word report and a sixteen-sheet Excel workbook, stamped DRAFT with its caveats built in. Your team finishes it.

Contract tools explain the contract. Project platforms hold what happened on the job. Senedra puts the clause, the change, the evidence and the payment position in one register.

Who it's for

It’s built for subcontractors and their QSs first. Main contractors and employers run the same registers on the same job.

Everything in the register comes straight from the contract.

Every line is quoted word for word and cited to its clause and page. No quote, no row.

Pilot places

See it on your own contract.

Send one contract, closed job or live, and see the register it produces. No pitch, no commitment.

We’re inviting a small group of commercial teams to run Senedra against their own contracts. No customer logos yet, by design; we’d rather earn them than borrow them.

Questions

Asked on every call so far.

How long does it take?+

The read takes a couple of minutes; going through the result takes an hour or two, far less than reading 60 pages cold.

Which contract forms does it read?+

It reads NEC4 (validated on a real package), plus JCT and FIDIC, and it's tested against contracts we marked up by hand. The changes the other side made to the standard form (Z-clauses, Particular Conditions) are read and cited too.

Where does my contract go?+

The read runs on our own machines and your contract text is never sent to a third-party AI model. Where documents and registers are stored, they are held encrypted in the UK or EU, never used to train anything, and deleted or returned at the end of the engagement, or sooner if you ask. During the pilot we ask you to redact first.

What does the pilot involve?+

You send one subcontract, real or anonymised. We run it, show you the register, and tell you honestly if it fits. No pitch, no commitment.
