Retrieve the bill and the filed tariff sheet that priced it, explain the charge against that sheet, surface the escalation route, and leave the arrangement itself to a billing adviser.
Ingesting the account, the disputed bill and the tariff schedule in effect from supported billing, CIS or meter-data sources.
02
Normalising rate codes, meter reads and charge lines, and carrying each one forward with its source.
Reason
03
Explaining each charge against the filed sheet that priced it, line by line.
04
Applying the jurisdiction, rate class and tariff version configured for that account.
05
Citing the tariff sheet and its effective date rather than paraphrasing a rate.
Decide
06
Flagging a meter doubt, a high-bill enquiry or a hardship signal as a dispute, not an enquiry.
07
Routing arrangements, adjustments and disconnection questions to a billing adviser.

08
Retaining the enquiry, the sheet cited, the adviser's answer and the escalation offered against the account.
09
Executing write actions only inside the approval boundaries agreed during implementation.
→Product statement
The agent explains and cites; a billing adviser decides what is charged, adjusted or arranged, and the utility answers to the regulator for the tariff.

High confidence
Goes to the billing adviser to release.

03Explanation
Read the sheet that priced it
Draw on the filed tariff, the meter reads and the back-billing and notice rules configured for that jurisdiction.
01Approved path
Read the tariff, not around it
Routine charge explanations arrive already cited to a sheet.
02Human review
Put advisers where the dispute is
Dispute signals and low-confidence answers are marked, so the adviser's read starts where the exposure sits.
04Build an evidence trail
The answer, the tariff sheet behind it and the adviser who released it stay on the account.

Break the correction rate down by rate class before you trust it. A small number of billing cohorts absorb most of the rework, so Nestack reports the adviser-correction rate by slice, not only in total.

Evidence-linked improvement
A cycle ends in a test, not an apology
The loop shuts when the miss is a case in the suite, not when it has been explained. That suite is what the next bill enquiry answered is measured against.
Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect
Adviser-correction rate rises in a rate class.
02Diagnose
Pull the enquiries and the sheets cited behind them until the cause narrows to one.
03Improve
Whatever changes ships against a version, with the enquiries that prompted it attached.
04Verify
Nothing ships until the affected cases pass a second time.
05Learn
The suite grows by one case; so does the tariff mapping.
Learn → DetectThe return edge. The next detection is measured against a longer suite than this one.
Typical build scope
