Collections & Payment-Arrangement AI Agent

What this agent does

Chases the balance, not the connection

Where the balance sits, read it from supported billing, CRM or payment sources.

When the records disagree, normalise the ageing and the payments applied, and carry each figure with its source.

Reason

Where an arrangement is due, assemble the arrears position and offer one from the carrier's approved set.

When a contact is proposed, apply the frequency, time-of-day and channel rules configured for that account's state.

Where a figure is put to a customer, bind it to the billing record it was read from.

Decide

When a dispute, Lifeline, hardship or medical-necessity signal appears, mark the account and stop the arrears path on it.

Where the account needs a decision the agent may not take, route it to the named collections adviser.

Out

Retain the contacts attempted, the arrangement offered, the adviser's decision and the outcome against the account.

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

→ Product statement

The agent works arrears in the carrier's own name; a named collections adviser decides suspension, restoration and any hardship claim.

No human action required

Stages 1 to 4 run unaided, and no line is suspended at any of them — the agent is arranging, and the adviser's lane opens at the confidence gate.

5DecisionBranches at the confidence threshold

High confidence

Goes to the collections adviser to agree.

Low confidence

Adds a hardship-team read first.

Adviser approval

The account is held with its arrears position, its flags and the confidence.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items

Suspending, restricting or restoring a service.

Agreeing a plan outside the carrier's approved set.

Contacting past the frequency configured for a state.

Deciding a hardship or medical-necessity claim.

Automation boundaryAgent acts unaided

✓Assemble the arrears position from the billing and payment record.

✓Offer an arrangement drawn from the carrier's approved set.

✓Apply the contact-frequency rules configured for that state.

✓Mark disputes, hardship and Lifeline signals, and hold the account.

Any write happens inside the boundaries agreed at implementation, never ahead of approval.

Using any name for the agent but the carrier's own.

Referring an account onward to a collection agency.

Enrolling a customer in recurring auto-debit.

Changes to contact, arrangement or suspension rules.

Work from the record

Draw on the ageing, the payments applied and the contact rules configured for that state.

01Approved path

Arrange it, do not pressure it

Routine arrears positions and approved arrangements arrive already assembled.

02Human review

Send review to the hard accounts

Disputes, hardship and Lifeline flags are marked, so the adviser's time starts where the risk sits.

04Build an evidence trail

The contact, the arrangement offered and the adviser who agreed it stay on the account.

How Nestack evaluates it

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

Affected slices

A healthy total can sit on one bad cohort

Flagged customers are the population an aggregate under-counts — too few to move the total, and the source of most adviser amendments. Nestack reports the amendment rate by slice, not only in total.

Slice performance — reported separately, not only in aggregateIllustrative example

Slice	Failure rate	Lift	Status
Accounts with an open dispute	5.5%	3.8×	Review
Lifeline and social-tariff lines	3.5%	2.4×	Review
Repeat and broken arrangements	2.5%	1.7×	Watch
Straightforward first arrears	0.9%	0.6×	Normal

Evidence-linked improvement

A cycle ends in a test, not a note

A cycle is done when the miss has become a test the next release has to survive. That suite is what the next account in arrears is measured against.

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

01Detect

Adviser-amendment rate rises in an arrears slice.

02Diagnose

The collections adviser who picked it up walks the contacts and the account back until one cause is left.

03Improve

Version-stamp the change and attach the contacts that exposed it.

04Verify

The affected cases run again, and a fail stops the release.

05Learn

It becomes a standing test, and the contact rules change with it.

Learn → DetectThe return edge. The next cycle starts against a longer suite than this one did.
