Construction Certified Payroll Automation With Human Certification

Start with the job, not the software

Before building a workflow, define the filing scope for the specific project. Record:

• the contract and project identity;
• the funding source and responsible agency;
• the governing jurisdiction;
• the wage determination and revision;
• the project clauses and applicable instructions;
• the current form or portal version;
• the filing route and deadline;
• the correction process; and
• the people authorized to review, certify, sign, and submit.

Do not let a prior project's setup become the default just because it already exists in a spreadsheet or software template. A workflow should stop when a required governing record is missing, stale, or disputed. It should send the issue to the named reviewer rather than filling the gap with a guess.

The U.S. Department of Labor publishes the [WH-347 form and supporting resources](https://www.dol.gov/agencies/whd/forms/wh347), including an [annotated guide](https://www.dol.gov/sites/dolgov/files/WHD/davis-bacon/wh347-annotated-guide.pdf). Those resources are a starting point, not a substitute for the contract, agency instructions, current legal guidance, or qualified review.

Build a source-of-truth map

A reliable process identifies which record owns each field and which records are only copies, exports, or generated outputs.

| Record | Authoritative source or owner to define | Allowed workflow action | Action that stays blocked | Evidence to retain | |---|---|---|---|---| | Clock events | Approved field-time source | Import and match to worker, project, and date | Change an original clock event without an approved correction | Original event, source ID, timestamp, correction history | | Approved timecards | Named field supervisor or approved timekeeping process | Freeze the approved weekly version | Treat unapproved hours as final | Approval, approver, version, cut-off time | | Worker identity | Approved worker or HR record | Match approved identifiers | Invent or merge identities automatically | Source ID, match rule, exception record | | Classification and apprentice status | Qualified reviewer using the governing records | Display the approved value and flag conflicts | Select or change status based on a model guess | Source document, revision, reviewer, decision date | | Payroll register | Payroll system and authorized payroll owner | Compare hours, rates, deductions, gross pay, and net pay | Rewrite posted payroll silently | Register version, payroll number, export receipt | | Fringe record | Approved payroll or benefit record | Compare the approved treatment to prepared output | Decide legal treatment or eligibility | Source record, calculation support, reviewer decision | | Wage determination | Governing project record and qualified reviewer | Lock the approved version to the project | Choose applicability or revision automatically | Document, revision, effective date, approval | | Certified-payroll report | Controlled preparation workflow | Generate a clearly labeled draft for review | Label the draft certified, signed, submitted, or accepted | Generated version, source snapshot, validation log | | Statement of Compliance | Authorized certifier | Present the final package for human action | Apply a signature or certification without that person | Signed record, signer identity, date, authorization evidence | | Agency submission | Authorized submitter and agency portal | Prepare the approved package for submission | Use credentials or submit without approval | Submission receipt, portal status, submitted version | | Corrections | Named correction owner | Create a new linked version | Overwrite the original filing or evidence trail | Reason, owner, timestamps, prior and new versions |

The map should also define a field dictionary. At minimum, cover project and contract IDs, payroll number, worker ID, work classification, journeyworker or registered-apprentice status, daily and weekly hours, rates, fringe credits or cash in lieu, deductions, gross pay, net pay, and certification fields.

Every field needs a name, format, source, owner, allowed values, transformation rule, and exception route. If two systems use different meanings for the same label, document the difference instead of forcing a match.

Freeze the weekly source package

Set a weekly cut-off for approved source records. The freeze should capture:

• the source system or document;
• the exact version or export;
• the owner who approved it;
• the approval time; and
• any open exceptions.

Late changes should not slide into the package unnoticed. Route them into an exception queue, record who made the change and why, and decide whether the prepared payroll must be regenerated and reviewed again.

This gives the reviewer a fixed package. It also makes a later correction traceable. Without a source freeze, people can end up reviewing one version while the workflow quietly builds another.

Route disagreements instead of hiding them

A useful workflow does not merely check whether a field is filled in. It looks for contradictions across records and stops the affected item for review.

Common exception routes may include:

• a worker identity that does not match across time and payroll records;
• hours tied to multiple projects or classifications;
• a missing or disputed apprentice-status record;
• daily or weekly hours that do not reconcile;
• a stale or unapproved wage-determination revision;
• a rate or fringe conflict;
• deductions that differ between the prepared record and payroll register;
• duplicate or skipped payroll numbers;
• a signature attached by an unauthorized person;
• a rejected submission; or
• a correction that supersedes an earlier version.

Each route needs an owner, required evidence, permitted action, escalation point, and closure rule. "Flagged" is not a complete status. The record should show who reviewed the issue, what evidence they used, what decision they made, and which version became current.

Keep preparation separate from certification

Preparation, review, certification, signing, submission, portal acceptance, and final reconciliation are different states.

A generated draft is not certified. A reviewed package is not signed. A signed package is not submitted. A submitted record is not necessarily accepted. A portal receipt does not prove that every underlying classification, hour, rate, fringe, or deduction was correct.

Use plain status labels that make those boundaries visible:

• source records collected;
• source package frozen;
• exceptions open;
• draft generated;
• human review complete;
• authorized certification complete;
• authorized signature complete;
• submitted;
• receipt captured;
• correction required;
• corrected version resubmitted; and
• final reconciliation complete.

Automation may move records between approved preparation steps. Human authority must remain visible at every decision, certification, signature, and submission gate.

Preserve every correction

Certified-payroll corrections should create new, linked records. Do not overwrite the original package.

Preserve the original, corrected, resubmitted, accepted, superseded, and archived states. For each change, retain the reason, owner, timestamp, affected fields, prior version, new version, review record, and any submission receipt.

That history matters when a payroll number changes, a classification is corrected, hours move between projects, a rate or fringe record is updated, or an agency requests a revised filing. The goal is a chain someone can follow without reconstructing it from email, memory, and overwritten spreadsheets.

Reconcile the full chain

The weekly process is not finished when a file uploads successfully. Reconcile the final chain across:

• approved field time;
• the payroll register;
• benefit or fringe records;
• the prepared certified-payroll output;
• the signed and submitted version;
• the portal or agency receipt;
• any correction and resubmission records; and
• relevant payment evidence.

Document every unresolved difference. Portal acceptance should be recorded as an event, not treated as proof that every underlying fact or legal conclusion was correct.

Test the workflow before live use

Use a synthetic test set before connecting worker, payroll, or agency data. Include made-up projects, workers, classifications, hours, rates, fringes, deductions, payroll numbers, signatures, submissions, rejections, and corrections.

The test should cover:

• missing and conflicting records;
• split projects and classifications;
• stale versions;
• duplicate identifiers;
• unauthorized actions;
• privacy and access controls;
• system outages and manual fallback;
• rollback and re-run behavior;
• correction history; and
• final owner acceptance.

The workflow should abstain when it lacks an approved source or authorized decision. A confident-looking guess is still a bad record.

A practical implementation checklist

Before any live rollout, the project owner should be able to answer these questions:

• Which contract, funding source, agency, jurisdiction, and instructions govern this project?
• Which wage determination and revision has a qualified reviewer approved?
• Which system or record owns each critical field?
• Who approves the weekly source freeze?
• Which conflicts stop preparation?
• Who reviews each exception?
• Who may certify, sign, and submit?
• How are credentials kept out of the preparation workflow?
• How are original and corrected versions preserved?
• What evidence closes each exception?
• What is the manual fallback when a system is unavailable?
• Which synthetic tests must pass before live data is allowed?

If those answers are unclear, adding automation will make the confusion move faster. Map the authority and evidence first. Then automate only the bounded preparation work that the owners have approved.
