What this agent does
Assembles the worksheet, not the certification
In
- 01
A revenue line is classified, and the classification is held with the system and the as-at date behind it.
- 02
A projection is reasoned, because 47 CFR 54.711(a) wants a good-faith estimate from your own procedures.
Reason
- 03
A quarter closes, and the Form 499-Q projection limb is the one with no system of record to point at.
- 04
A revision would decrease a contribution, and that window shuts on 31 March of the following year.
- 05
An upward correction stays owed after the same window, so the clock runs in one direction only.
Decide
- 06
A due date lands on a weekend, and it shifts — a form counts as filed when USAC receives it, not before.
- 07
A de minimis year arrives, and the annual Worksheet is still owed; the other fund and fee duties have no exemption.
Out
- 08
A registration detail changes, and the Worksheet instructions give one week to report the change.
- 09
Execute write actions only inside the approval boundaries agreed during implementation.
Product statement
The agent assembles and traces; a named officer examines the Worksheet, certifies it and files it, and the filer answers.
Example workflow
One revenue line, source to filing
- 1Revenue records receivedBilling, rating and general-ledger extracts, each with its as-at date
- 2Line coverage assembledProduct, jurisdiction, customer class and the system each figure was taken from
- 3Worksheet assembledThe annual blocks, the quarterly projection and the reasoning behind each
- 4Controls appliedProvenance checks, true-up checks, revision-window checks and completeness confidence
No human action required
Stages 1 to 4 run unaided, and nothing is certified at any of them — the agent is assembling, and the regulatory lane opens at the completeness gate.
Goes to the certifying officer to sign.
Adds a regulatory counsel read first.
Regulatory review
The assembly is held with its provenance, its projections and its gaps.
Certify and file · Append provenance · Send to counsel
Filed — by a named officer

- 7Outcome evaluatedProvenance completeness, true-up variance, counsel corrections and what audit found
Corrections
Each counsel correction is counted in the evaluation.
What should not run autonomously
Human approval stays in control

8 items
- Certifying a Worksheet under the 18 U.S.C. § 1001 warning.
- Signing or filing the annual or quarterly Worksheet.
- Deciding a revenue line sits in the contribution base.
- Judging a projection to be a good-faith estimate.
Automation boundary
Agent acts unaided
- ✓Trace each revenue figure to the system and the as-at date behind it.
- ✓Bind each worksheet line to the product and jurisdiction it reports.
- ✓Hold the reasoning behind each revenue projection.
- ✓Track the revision window and the true-up against.
Nothing is certified or filed except by a named officer, inside agreed boundaries.
- Claiming de minimis status for a filing year.
- Telling a customer what a surcharge recovers.
- Electing the Block 6 confidentiality certification.
- Changes to classification rules or projection method.
Example output
One revenue line, annotated
Our billing and revenue-assurance agent reconciles these records; the revenue it reconciles is the revenue this page classifies.

Why no base call here
Base membership is an officer call under 47 CFR 54.711(a), not a model output.
What the score decides
Below the configured threshold the assembly picks up a counsel read before.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Every revenue line
From the system that billed it
Same fund, opposite end
Our E-Rate bidding and certification agent stands on the applicant side of universal service; this page is the contributor side, and the money runs the other way.
A one-way clock on corrections
The Form 499-A instructions shut a decreasing revision on 31 March of the year after the filing was due; an upward correction stays owed after it, and delinquency draws interest and a remedial collection charge.
What the Court decided, and did not
FCC v. Consumers’ Research, decided 27 June 2025 and not unanimous, reversed the Fifth Circuit en banc ruling of 24 July 2024; it left tax versus fee undecided and reaffirmed the intelligible-principle test.
Build an evidence trail
The revenue line, the system it came from and the officer who certified stay on the worksheet.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls
Six filters between the model and the worksheet
Six filters in series, each finer than the last. Whatever survives is set out in the map below.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether an assembly may stand
- L3
- Puts the certification in a person's hands
- L4 – L5
- Keep the line and the system behind it
- L6
- Holds the worksheet unfiled when signals degrade
How Nestack evaluates it
Evaluate the whole assembly — not only the worksheet that comes out.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the worksheet an officer certifies
- E1Final-output evaluationDid the assembly name the system behind each revenue line?
- E2Step-level evaluationDid the agent read the right period, the right jurisdiction and the current extract?
- E3Tool evaluationDid it read and write the correct revenue record and the correct filing period?
- E4Confidence calibrationDo low-confidence assemblies actually attract more counsel corrections?
- E5Slice evaluationHow does performance change across specific revenue categories?
- E6Business outcomeHow many assemblies needed a correction before the officer certified?
Floor — the outcome the filer answers for
Failure modes
Where each failure originates in the agent
Seven failure modes, each placed where it starts inside the agent.

Affected slices
One revenue category absorbs the corrections
A category-level revenue-provenance figure can read clean while one category carries most of the corrections. Nestack reports the counsel-correction rate by revenue category, not only in total.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Bundled and packaged services | 8.6% | 3.7× | Review | |
| Interconnected VoIP revenue | 6.1% | 2.6× | Review | |
| International end-user revenue | 3.8% | 1.6× | Watch | |
| Interstate end-user voice | 2.2% | 0.9× | Normal |

Evidence-linked improvement
What an untraceable revenue line costs
A cycle ends when the missed revision window is a standing case. That suite is what the next worksheet assembled is measured against.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Counsel-correction rate rises in one revenue category.
- 02
Diagnose
The revenue category that was right for the invoice and wrong for the worksheet is read back until one cause remains.
- 03
Improve
Changes leave numbered, and the revenue lines behind them travel attached.
- 04
Verify
A single failing revenue case is enough to stop the release.
- 05
Learn
The case is kept, and the classification rules are rewritten alongside it.
Learn → Detect
The return edge. The next worksheet is measured against a suite one case longer.
Typical build scope

Next step · Telecom AI agent
Build a USF contribution agent around a revision window that shuts one way.
Show us how a revenue line reaches Form 499 today and who certifies it. Which way does your revision clock run — one way, because a decreasing revision expires on 31 March of the year after and an upward one does not. Red-light status under 47 CFR 1.1910 reaches the agency.
