Contract Management AI Agent

Unpack a signed portfolio into a register of duties, each one citing the clause it came from and dated to when it falls due, and hold that register for a named commercial owner.

What this agent does

Registers the obligation, never waives it

In
01

A contract is loaded, and the duties it creates are written out as lines, each with an owner and a date.

02

A schedule nobody has reopened since signature is read alongside the body it hangs off.

Reason
03

An obligation falls due, and it is dated from the clause that set the date, not from the filing date.

04

A duty runs toward the supplier, and the one running the other way is registered in the same pass.

05

A clause carries its exception in a second sentence, and the exception travels with the summary.

Decide
06

An amendment, side letter or change order is bound to the contract it altered before either is read.

07

A rebate, credit or price review has to be claimed, and the claiming is what the register dates.

Out
08

A clause resists extraction, and that resistance is recorded as a finding rather than left as a blank.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

Reading, extraction and dating belong to the agent. Meaning belongs to a named commercial owner, who decides what a clause obliges and acts on it.

Example workflow

One contract, signature to register

AgentHuman
1Signed contract receivedExecuted agreements, schedules, amendments, side letters or change orders
2Obligations extractedThe duty, the party who owes it, the date it falls due and the clause it was read from
3Register entries raisedEach obligation, its owner, its due date and the extraction confidence
4Controls appliedClause-citation checks, amendment checks, date checks and extraction confidence
No human action required

Stages 1 to 4 run unaided, and nothing is waived or served at any of them — the agent is extracting, and the owner lane opens at the confidence gate.

5DecisionSplits at the extraction gate
Clause cited cleanly

Goes to the commercial owner to confirm.

Anything unreadable

Adds a contract-manager read first.

Commercial review

The obligation is held with its clause, its due date and the confidence it was read at.

7Outcome evaluatedClause-citation accuracy, amendment coverage, owner corrections and what review found
Corrections

Each commercial-owner correction is counted in the evaluation.

Example output

One obligation, annotated

Our contract review agent reads a draft for legal risk before signature; this is the obligation register after it, and below is one entry exactly as the agent leaves it.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every obligationFrom the contract that created it
03Evidence

Where the evidence is used

Where an obligation was missed and the date has already gone by, the owner records what was forfeited against the clause, the entry reopens with its extraction attached, and the case joins the suite.

01Approved path

The clause outlives the deal

Negotiation ends and the file closes, but the duties it created run on for years, in schedules nobody has reopened since the day of signature.

02Human review

What was checked, and not found

No repository examined here states a duty. A contract repository stores documents, versions them and controls who may open them; a register of obligations is a different artefact, stating what is owed, by whom and by when, with a named owner against each line. Almost every company has the first and believes it has the second. Nothing in a signed document records whether the duty was performed, so the register holds what was extracted and what was not, and performance is asserted by the owner rather than read off the page.

04Build an evidence trail

The obligation, the clause it came from and the owner who holds it stay together.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

How Nestack evaluates it

Evaluate the whole extraction — not only the register that comes out.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Affected slices

Rebate clauses absorb the corrections

A type-level extraction figure can read clean while rebate and credit clauses carry most of the entries an owner had to correct. Nestack reports the correction rate by obligation type, not only in total.

Evidence-linked improvement

What an unread schedule costs

A cycle closes when the missed obligation is a regression case. That suite is what the next contract loaded is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Correction rate rises on rebate and credit clauses.

02Diagnose

The obligation buried in a schedule to a contract nobody has opened since signature is worked backwards until one cause is left standing.

03Improve

Number the change; the contracts that drove it are filed beneath it.

04Verify

One contract case still failing holds the entire release back.

05Learn

It is retained permanently, and the extraction rules move with it.

Learn → DetectThe return edge. The next contract is measured against a suite one case longer.

Typical build scope

Next step · Procurement AI agent

Build a contract management agent around the obligation your last portfolio never registered.

Show us one contract you signed and the schedule nobody has opened since. Not a repository of documents. A register of duties, each with an owner and a date against it. An obligation the company owed and forfeited by silence comes back as a finding.
