The project record matters
Certified payroll needs job, contract, wage determination, classification, and worksite information tied to the employee's hours.
Davis-Bacon records for contractors and subcontractors
Certified Payroll and Prevailing Wage Guide
Certified payroll is not a form-filling exercise. It is the final proof that a contractor paid the right worker, in the right classification, on the right project, for the right hours, at the right rate, with fringe benefits handled correctly.
What changed for employers
The DOL Davis-Bacon page explains that Davis-Bacon and Related Acts apply to contractors and subcontractors on federally funded or assisted contracts over $2,000 for construction, alteration, or repair of public buildings or public works.
The same DOL page notes that the 2023 Davis-Bacon final rule took effect on October 23, 2023, while a June 24, 2024 nationwide preliminary injunction affects three specific provisions. DOL states that the remainder of the final rule remains in effect.
DOL's forms page points contractors to the WH-347 certified payroll form and instructions. In practice, the form is only as reliable as the time, classification, project, fringe, overtime, and deduction records behind it.
Classifications drive rates
The same worker may need different rates when performing different classifications on a covered project.
Fringes need evidence
Cash fringe, bona fide benefit plans, and deductions must be handled with clear payroll and benefits support.
A certified payroll evidence framework
A public works contractor should build the certified payroll file before the first week of work. Waiting until the first WH-347 is due creates pressure to reconstruct job codes, classifications, overtime, and fringe calculations from incomplete field notes.
The best workflow starts at project setup. Payroll, estimating, project management, and field supervisors should agree on contract identifiers, wage determinations, job classifications, cost codes, overtime rules, fringe handling, subcontractor responsibilities, and who approves weekly payroll.
Set up the covered project
Create project, contract, funding, prime/subcontractor, wage determination, and reporting fields before any employee clocks time to the job.
What to document: Contract number, wage determination, project code, reporting owner, and approval routing.
Map classifications to tasks
Translate field work into wage classifications supervisors can apply consistently. Avoid using generic labor categories when the wage determination requires specificity.
What to document: Classification matrix, supervisor guide, and employee assignment rules.
Capture daily time by project and classification
Track hours by employee, day, project, cost code, classification, and worksite. Splitting hours correctly is essential when workers perform multiple classifications.
What to document: Daily timecards, job transfer records, approvals, and field notes.
Calculate rates, fringes, and overtime
Apply the prevailing wage, fringe treatment, overtime, deductions, and any cash-in-lieu or benefit credit rules before payroll is certified.
What to document: Rate table, fringe calculation, payroll register, and benefit support.
Archive the weekly certified package
Keep the certified payroll report, statement of compliance, time records, wage determinations, approvals, corrections, and subcontractor submissions together.
What to document: WH-347 package, signed certification, time detail, and correction log.
Certified payroll risk matrix
Prevailing wage problems usually come from weak project setup or weak daily classification records.
| Risk | Why it matters | Payroll consequence | Control |
|---|---|---|---|
| Worker performs two classifications in one day | Each classification may require different prevailing rates. | Underpayment if all time is paid at the lower rate. | Daily classification split and supervisor approval. |
| Fringe benefit credit is unsupported | Benefit credit must be tied to bona fide benefit costs or cash equivalents. | Back wage exposure and reporting correction. | Fringe worksheet, benefit invoices, and payroll register support. |
| Subcontractor submits late or inconsistent payroll | Prime contractors often need to manage downstream documentation. | Project payment delays, audit pressure, and compliance gaps. | Subcontractor submission calendar and validation checklist. |
| Overtime is calculated from the wrong base | Overtime on covered work may interact with prevailing wage and CWHSSA requirements. | Incorrect overtime premium and possible back wages. | Overtime test payroll and weekly review. |
| Field supervisors choose vague job codes | Vague codes do not prove classification accuracy. | Rejected certified payroll package or classification dispute. | Field classification guide and job-code restrictions. |
How to audit your own payroll data
A useful review starts with the records the business already owns. Do not begin with abstract policy language. Begin with the employee, the pay period, the schedule, the time record, the manager approval, the payroll calculation, and the source document that explains the exception.
The review notes below turn the risk matrix into a practical audit path. They are written for payroll and HR teams that need to brief managers, accountants, executives, or outside advisors without losing the operational facts.
Worker performs two classifications in one day
Start with the source record. Pull the timecard, schedule, employee profile, payroll register, approval history, and any manager notes that explain why this issue appeared. The goal is to prove what happened before the pay period closed, not to reconstruct the story weeks later.
What the signal usually means: Each classification may require different prevailing rates. That does not always mean the employer made a payroll mistake, but it does mean payroll should slow down, review the facts, and avoid treating the issue as a routine exception.
Why the business should care: Underpayment if all time is paid at the lower rate. A clean process uses daily classification split and supervisor approval. so the same issue is handled consistently by different managers, locations, and payroll administrators.
Fringe benefit credit is unsupported
Start with the source record. Pull the timecard, schedule, employee profile, payroll register, approval history, and any manager notes that explain why this issue appeared. The goal is to prove what happened before the pay period closed, not to reconstruct the story weeks later.
What the signal usually means: Benefit credit must be tied to bona fide benefit costs or cash equivalents. That does not always mean the employer made a payroll mistake, but it does mean payroll should slow down, review the facts, and avoid treating the issue as a routine exception.
Why the business should care: Back wage exposure and reporting correction. A clean process uses fringe worksheet, benefit invoices, and payroll register support. so the same issue is handled consistently by different managers, locations, and payroll administrators.
Subcontractor submits late or inconsistent payroll
Start with the source record. Pull the timecard, schedule, employee profile, payroll register, approval history, and any manager notes that explain why this issue appeared. The goal is to prove what happened before the pay period closed, not to reconstruct the story weeks later.
What the signal usually means: Prime contractors often need to manage downstream documentation. That does not always mean the employer made a payroll mistake, but it does mean payroll should slow down, review the facts, and avoid treating the issue as a routine exception.

What the signal usually means: Vague codes do not prove classification accuracy. That does not always mean the employer made a payroll mistake, but it does mean payroll should slow down, review the facts, and avoid treating the issue as a routine exception.
Why the business should care: Rejected certified payroll package or classification dispute. A clean process uses field classification guide and job-code restrictions. so the same issue is handled consistently by different managers, locations, and payroll administrators.
30-60-90 day implementation plan

| Days 31-60 | Configure job costing, classification capture, supervisor approvals, rate tables, fringe tracking, and weekly certified payroll review. | Payroll, PMO, field supervisors | Configuration notes, test timecards, payroll test, and supervisor guide. |
| Days 61-90 | Run two certified payroll cycles with QA, validate subcontractor packages, archive support, and create correction procedures. | Payroll compliance owner | QA checklist, certified packages, subcontractor log, and correction register. |
How TimeTrex fits the workflow
TimeTrex job costing is especially relevant for certified payroll because public works payroll depends on where labor happened and what work was performed. A generic clock-in is not enough when a worker moves across projects, departments, tasks, or classifications.
TimeTrex can support time and attendance, job costing, scheduling, payroll, reports, and document workflows that help contractors keep project records closer to payroll. That matters when a weekly certified payroll package needs to show the source behind the number.
The customer value is not just compliance. Better certified payroll records reduce payment delays, project disputes, rework, audit stress, and the cost of reconstructing job histories after a project closes.
| TimeTrex area | Why it matters | Relevant page |
|---|---|---|
| Job costing | Tracks labor by project, task, department, branch, and cost center for project-level payroll evidence. | TimeTrex Job Costing |
| Time and attendance | Captures daily hours and approvals that feed certified payroll. | TimeTrex Time and Attendance |
| Payroll | Processes rates, deductions, pay stubs, tax reports, and payroll records. | TimeTrex Payroll Software |
| Document management | Helps organize supporting records, forms, and approvals. | TimeTrex Document Management |
Make the payroll record easier to trust
TimeTrex helps employers connect scheduling, time tracking, approvals, leave, job costing, payroll, reporting, and employee self-service so the record behind every paycheck is easier to review before it becomes a correction, notice, or employee dispute.
Reports and manager routines to build
Payroll controls work only when managers can use them during a real workweek. A policy that requires payroll expertise at every decision point will fail in restaurants, clinics, shops, field crews, construction sites, and remote teams. The better model is a short manager routine supported by reports.
For this topic, managers need three habits: capture the fact while it is fresh, route exceptions before payroll closes, and avoid informal promises that conflict with payroll or legal requirements. Payroll then reviews the exception report, tests the calculation, and keeps the evidence.
Employee communication matters too. Employees do not need a legal memo; they need to know how to report a missed punch, disputed balance, location change, interrupted meal, tip issue, classification concern, or payroll deduction question. A simple self-service path reduces hallway conversations and protects the record.
| Routine | Manager behavior to reinforce | Payroll reason |
|---|---|---|
| Routine 1 | Contract number, funding source, and covered project fields are configured. | Review before payroll is approved so errors are corrected while managers and employees still remember the facts. |
| Routine 2 | Wage determination and classifications are stored with the project record. | Add the control to manager training so the rule is followed during daily operations, not only during year-end review. |
| Routine 3 | Supervisors have a plain-language classification guide. | Review before payroll is approved so errors are corrected while managers and employees still remember the facts. |
| Routine 4 | Employees can allocate time by project and classification. | Add the control to manager training so the rule is followed during daily operations, not only during year-end review. |
| Routine 5 | Fringe benefit treatment is documented before payroll runs. | Review before payroll is approved so errors are corrected while managers and employees still remember the facts. |
| Routine 6 | Overtime rules are tested before the first covered payroll. | Add the control to manager training so the rule is followed during daily operations, not only during year-end review. |
Certified payroll mistakes
Certified payroll errors are rarely isolated. One weak field in setup can ripple into every weekly report.
Using one rate for mixed work
A worker who performs multiple classifications may need hours split by classification.
Better move: Make classification selection part of daily time entry and supervisor approval.
Treating fringes as an afterthought
Fringe treatment can affect hourly wage, cash in lieu, benefit credit, and overtime review.
Better move: Build a fringe worksheet before the first payroll run.
Letting field notes live outside payroll
If field records are not connected to payroll, the certified report may be hard to defend.
Better move: Use job and classification fields in the timekeeping workflow.
Ignoring subcontractor QA
A prime contractor can be surprised by late or inconsistent subcontractor records.
Better move: Set weekly submission deadlines and review subcontractor packages against project rules.
Waiting until audit to archive support
Documents become hard to find after employees, managers, or subcontractors move on.
Better move: Archive the complete weekly package as part of payroll close.

FAQ
What is certified payroll?
Certified payroll is a payroll report and certification used on certain public works or government-funded construction projects to show workers were paid required wages and benefits.
What is the WH-347 form?
WH-347 is a DOL certified payroll form used by contractors and subcontractors, with instructions, for Davis-Bacon and related work.
Does every construction project require certified payroll?
No. Requirements depend on the contract, funding, jurisdiction, and applicable prevailing wage laws. Employers should review the contract and official wage requirements.
Why is job costing important for certified payroll?
Certified payroll often requires proof of which project, classification, and hours were worked. Job costing helps connect labor time to that project evidence.
Can one employee have multiple rates in one week?
Yes. If the employee performs different covered classifications, hours may need to be split and paid according to the correct classification and rate.
How can TimeTrex help?
TimeTrex can connect time tracking, job costing, payroll, reports, and document workflows so weekly certified payroll packages are easier to support.
