When to Keep Certified Payroll In-House (and When to Bring in Support)

Last Updated: October 2026

Certified payroll reports are due every week a job is active, on every active job. Union reporting runs on a separate schedule that varies by local. Both usually land on the same person, alongside running payroll, closing the month, and answering general contractor questions about last week’s submission. At some point most contractors ask whether to keep doing this in-house or bring in help.

Most in-house payroll vs. outsourcing advice answers a different question: who cuts the checks. Certified payroll and union reporting are compliance obligations that run through payroll. The deadlines, the documentation requirements, and the risk are all different, and so is the decision.

There are also three options rather than two: fully in-house, in-house with purpose-built software, or partner-led support. 

Key Takeaways

✓  There are three options: fully in-house, an in-house team supported by purpose-built software, and partner-led support through Managed Services.

✓  None of the three removes your involvement. You own the data, you verify the reports, and you sign off.

✓  In-house works well in a single state, at a low project volume, on federal-only work, with documented expertise held by more than one person.

✓  Growth is the most common trigger for reevaluating. More prevailing wage and union projects mean more rate sets, more reporting formats, and more hours. Turnover in the payroll seat is second.

✓  Calculate the real cost first: weekly labor hours, rework, coverage during PTO or a resignation, audit exposure, and the projects you can't bid without back-office capacity.

How Certified Payroll and Union Reporting Differ From Standard Payroll

Standard payroll is a process. Certified payroll is a process plus a proof burden: documentation, in a specified format and on a specified schedule, showing that the right rates were paid to the right classifications and that fringe benefits were funded correctly. Union reporting carries a second proof burden with separate rules.

Six differences account for most of the added workload

• The cadences don’t align. Payroll departments are generally built around a biweekly or semimonthly cycle. Certified payroll reports are due weekly per active job. Union reporting often runs monthly and varies by local. One payroll period can feed three reporting deadlines with no shared timing.
• Fringe benefits follow separate rules. Cash fringe payments and bona fide plan contributions report differently, and annualization applies. Union agreements add their own contribution rates, funds, and reporting formats.
• Federal requirements are the baseline, not the ceiling. The WH-347 covers federal work and is sufficient for contractors working federal-only. State and local requirements stack on top: separate forms, separate portals, separate submission rules.
• Union rules vary by local. Rates, fringe contributions, and fund reporting requirements differ from agreement to agreement, including within the same trade. There is no single union reporting standard.
• Obligations differ by role on the job. General contractors are often responsible for collecting and reviewing subcontractor reports before submission to the awarding agency. Subcontractors submit into the general’s process on the general’s timeline. Contractors working both ways run both processes.
• Classifications and apprentice ratios require judgment. Determining a worker’s classification and staying within apprentice-to-journeyworker ratios depends on understanding the work itself.

The question isn’t whether your team can run payroll. It’s whether your team can defend this payroll in an audit two years from now, on every job, under every agreement, in every jurisdiction you work in.

In-House Payroll Reporting vs. Outsourcing: The Three Real Options

Option 1: Fully In-House and Manual

Your payroll staff sources rates, pulls hours, applies classifications, calculates fringes, and builds reports, typically using your existing payroll system plus spreadsheets developed over time.

The cost is hours rather than a line item, and it concentrates process knowledge in one or two people. For a meaningful number of contractors this is still the right answer.

Option 2: In-House Team, Purpose-Built Software

Your team retains ownership of the process. The software stores the rates your team maintains, calculates wages and fringes against them, and generates the WH-347 along with state and local forms.

Rate sourcing stays with your team. The software makes rates and forms manageable in-house rather than manual, which suits a payroll person who knows what a correct report looks like but doesn’t have twelve hours a week to assemble one by hand across six jobs.

Option 3: Partner-Led Support

Our Managed Services team partners with you on rate sourcing, building and maintaining rate tables tailored to your business, monitoring for rate changes, generating certified payroll reports, and managing submissions.

You own the data, provide project and payroll inputs, verify that reports are correct, and sign off. Partner-led reduces manual assembly work. It does not remove your review.

This fits when the constraint is bandwidth or expertise rather than tooling: your team doesn’t have the available hours, you’re growing faster than you can hire, or you’ve taken on work in jurisdictions or under agreements nobody on staff has worked with.

The Case for Keeping It In-House

Points North sells software and managed services. Even so, plenty of contractors should keep certified payroll in-house.

In-house holds up when most of the following are true:

• One state, one broad project type, no union agreements layered on top.
• Prevailing wage work is a modest share of revenue, and you’re not bidding to grow it.
• Expertise exists on staff and isn’t held by a single person.
• The process is documented well enough for someone else to pick up in a week.
• Your team has the capacity to track rate changes and wage determination updates without displacing other work.

Cost discipline is a legitimate reason. If the process works, the audit history is clean, and the hours are hours you can afford, in-house is defensible. The question is what would have to change for that answer to flip.

Six Signals It’s Time to Bring in Support

These conditions generally indicate in-house management has stopped working.

1. Project count is growing and each new project adds a rate set. Certified payroll effort scales with active jobs, not revenue. Each additional prevailing wage or union project brings its own rates, agreement terms, and reporting requirements. This is the most common trigger we see.
2. You’re managing union agreements. Multiple locals mean multiple rate structures, multiple sets of fringe rules, separate fund reporting, and separate cadences. Add prevailing wage on the same jobs and the reconciliation work compounds. Manual processes break here most often.
3. You’ve moved beyond federal requirements. Federal-only work on the WH-347 is manageable for most teams. State and local requirements multiply the effort: new forms, new portals, new submission rules, new determinations to track. A process built for federal work rarely extends to a new jurisdiction unchanged.
4. One person is the whole process. If reports go out because one specific person makes them go out and there’s no documented backup, that’s a dependency rather than a process. It typically surfaces the week after a resignation.
5. Compliance reporting consistently costs overtime. Reports built on Saturdays, or a month-end close slipping because payroll is buried in WH-347s and fund reports, means the cost has moved beyond the payroll department.
6. You’ve had a correction, restitution request, or withheld progress payment. Withheld payments turn a compliance problem into a cash flow problem. Catching up on corrections while producing current reports is difficult with the same team that fell behind.

How to Calculate What In-House Compliance Reporting Costs

The cost is distributed across people who don’t bill for it, which is why it’s routinely underestimated. Seven inputs:

• Fully loaded labor. Hours per weekly cycle × loaded hourly rate × 52. Six hours a week at a loaded rate of $45 is roughly $14,000 a year before anything goes wrong. Track actual hours for two weeks rather than estimating; the real figure usually runs higher.
• Opportunity cost. What those hours would otherwise produce: job costing, cash flow forecasting, a faster close.
• Bid capacity. If back-office capacity is the reason you’re passing on prevailing wage or union work, or bidding cautiously on it, the cost includes revenue not pursued. People and systems in place are what make bidding on that work realistic.
• Rework. Corrections, resubmissions, and back-and-forth with agencies, funds, and general contractors.
• Exposure. Restitution, withheld payments, and internal time spent responding to an audit, which falls on senior staff.
• Coverage risk. The cost of one week of PTO in the payroll seat, and the cost of a resignation.
• Existing budget. Tooling, training, and continuing education belong on the in-house side of the ledger.

Questions to Ask a Partner Before Handoff

These questions apply to any provider, including us and including our competitors.

• How do rate changes and new wage determinations get caught mid-project?
• What happens during an audit? Who produces the backup documentation, and how quickly?
• How do you handle states we haven’t worked in yet?
• What does the transition actually look like — timeline, parallel run, historical data migration?
• What stays inside our systems, and what leaves them?

On transition risk specifically, the highest-risk window is the first four to six weeks, when historical data is being migrated, and nobody has fully absorbed the new process, ask for a parallel run.

A Simple Decision Framework

Seven criteria, and where each one tends to point.

Landing in more than one row is common, and generally points to a combination of software and partner support rather than either extreme.

Frequently Asked Questions About In-House vs Outsourced Certified Payroll

Making the Call

Certified payroll is a compliance obligation with a weekly deadline, and for many contractors union reporting sits alongside it with separate rules and a separate calendar. The right approach depends on how many jurisdictions you work in, how many agreements you manage, how deep your in-house expertise runs, and how much risk you’re willing to carry.

For contractors working in one state on federal jobs with a documented process and a clean audit history, in-house is the answer.

For most contractors we talk to, the answer is neither extreme. Keep your team, your data, and your oversight, and stop doing by hand what doesn’t need to be done by hand.
