California public works · Certified-payroll compliance
Public work, held to a provable standard.
Aeternus Dynamics runs the certified payroll and prevailing-wage compliance that decides whether California public projects get paid. Every filing is checked against the rules that withhold money, and nothing is submitted until it passes.
Why it matters
One wrong wage determination, a missed fringe, a slipped apprentice ratio, or a late eCPR filing, and the awarding body holds your money.
Most of these errors are invisible on a read. They surface months later, at audit, as withheld progress payments, penalties, and in the worst case debarment.
The work is not hard. It is unforgiving. That is exactly the kind of work a system should never get wrong.
Capabilities
One firm for the paperwork that governs public work.
The mandated filings, the advisory around them, and the business development to win more of the work. Certified payroll is where we start.
Certified payroll & prevailing wage
Weekly certified payroll to DIR eCPR and WH-347: wage determinations locked to the bid date, base and fringe verified, overtime and classification checked, apprentice ratios and DAS-140/142 tracked. Plus IRA clean-energy prevailing wage and apprenticeship, so developers keep the full 5× energy tax credit.
How we do the workProject & labor
Payment & registration
The pre-flight gate
Nothing files unless it is provably correct.
Certified payroll is due weekly through DIR eCPR. Before any filing leaves, it runs a pre-flight check against the exact rules that get contractors penalized. If a single check fails, it does not submit.
We also run retroactive audits and pursue withheld-payment recovery, and we file on your existing setup. A compliance firm, not a law firm.
Audit my last filingThe standard
Provably correct is the whole product.
Most compliance services check their work by reading it. We engineered the reading out. Each filing reconciles against the printed determination and the statutes that carry penalties, and it is blocked the moment a number does not add up.
The work
Across California infrastructure, energy, and public buildings.
How it works
From exposed to audit-proof in three moves.

Handled every week
We prepare, gate, and file each week, and grow with you across every regulated line as you scale.
A determination that cannot be proven is not a determination. It is a liability waiting for an audit.The Aeternus standard
The firm
Built to be trusted with the filing.
- A gate, not a promise.
Filings are verified against the rules and reconciled to the determination before they leave. Correctness is enforced, not asserted.
- We file on your setup.
No forced software switch. We work inside the tools and eCPR account you already use.
- A compliance firm, not a law firm.
We handle preparation, verification, and filing. Legal disputes stay with your counsel; our scope is stated plainly in every engagement.
Proof
Proof, not adjectives.
We are building our public client roster deliberately, one engagement at a time. Until those names are ours to share, here is the proof that does not depend on a logo wall.
Every determination checked against its own math
Each filing re-adds the base rate and every fringe line and confirms it equals the total the determination prints. If it does not reconcile, it does not file.
Eleven failure modes, zero permitted
Wage determination, base-plus-fringe, apprentice ratio, overtime, classification, and active registration, checked before submission rather than after.
On your setup, on the record
We file through the eCPR account you already use, quantify exposure in dollars, and stand behind the work as a compliance firm, not a law firm.
Founding public-works clients get the free audit, priority onboarding, and a locked first-year rate.

Straight answers
Questions contractors ask first.
Do you only do certified payroll?
No. It is the flagship, but we run the full slate: clean-energy prevailing wage and apprenticeship, DBE/MBE reporting, preliminary notices and liens, registration and licensing, OSHA, SWPPP, worker classification, I-9/E-Verify, insurance tracking, construction consulting, government contracting, advisory, and business development. One team across every line.
Do you give legal advice?
No. We are a compliance and advisory firm, not a law firm. We handle preparation, verification, and filing. Disputes, appeals, and debarment defense belong with licensed counsel.
How fast can you start?
This week. We begin with a free audit, onboard your active projects, and take over the weekly filing from there.
What does it cost?
The audit is free. Ongoing compliance is a flat monthly fee per active project. Recovery, federal, and advisory work is scoped per engagement.
Do I have to switch payroll tools?
No. We operate on your existing setup and file to DIR eCPR directly. If you have no tool, we handle that too.
