Certified Payroll Software for Indiana Contractors

7 min read · Updated July 31, 2026

If certified payroll is a person plus a spreadsheet plus hope, that is a configuration problem with a known fix.

Certified payroll is not a report you generate. It is a sworn statement, and the signature carries real liability.

What certified payroll actually requires

Certified payroll is not a report you generate. It is a sworn statement. Under the Davis-Bacon and Related Acts, contractors and subcontractors on covered federal projects submit weekly payrolls plus a signed statement of compliance, and the signature carries real liability. The U.S. Department of Labor publishes the requirements and the optional WH-347 form most agencies expect.

The form itself is where generic systems fall apart. Each row needs the worker, their trade classification, hours worked by day on that specific project, the prevailing wage rate for that classification, gross pay for the project against gross pay for all work, itemized deductions, and net pay. Fringe benefits have to be shown either as payments into approved plans or as cash paid in lieu.

Now put a real week on top of that, the kind I see on our clients' jobs every month. One carpenter works Monday and Tuesday on a school addition at one wage determination, Wednesday on a private job at your standard rate, and Thursday and Friday back on the school as a foreman at a different classification. That single employee produces three pay rates, two classifications, and one project split across two reporting periods.

A system that cannot model that will not produce a correct WH-347. No amount of clever spreadsheet work fixes it, because the underlying time data was never captured with the job and classification attached.

Where generic payroll software breaks

Most contractors do not discover the gap during a sales demo. They discover it during the first audit, or the first time an awarding agency rejects a submission and holds progress payments.

In my experience the failures cluster in five places, and I see the same five almost every time.

Job and classification are not on the time record. If a crew clocks in against a company, not a cost code and a trade, the certified payroll report has to be reconstructed after the fact. Reconstruction is where errors enter.

Fringe benefits are treated as a single deduction. Certified payroll needs fringes itemized and attributed. A lump health insurance line will not satisfy a reviewer who has to see whether the fringe portion of the prevailing wage was actually met.

Multiple wage determinations cannot coexist. Plenty of systems support one pay rate per employee, sometimes two. Prevailing wage work needs a rate that changes by project, by classification, and sometimes mid-week.

Apprentices are handled as regular employees. Registered apprentices are paid a percentage of the journeyman rate tied to their step, and the ratio of apprentices to journeymen on site is itself regulated. A system with no apprentice step logic gets this wrong quietly.

Reporting is generic, not statutory. Exporting hours to Excel is not the same as producing the WH-347 with a statement of compliance. Some agencies also require their own state or municipal format on top of the federal one.

What to look for in certified payroll software

Here is the checklist I actually use with contractors, in the order that matters.

Capability	Why it matters	The question to ask a vendor
Job-level time capture	Certified payroll is impossible to produce accurately after the fact	Can a worker clock in against a job and a trade classification, from the field, offline?
Multiple wage determinations	One employee routinely spans several rates in one week	Show me one employee, three classifications, two jobs, in the same pay period.
Fringe benefit attribution	Reviewers must see the fringe portion met, itemized	How are fringes shown on the WH-347, plan payments or cash in lieu?
Apprentice step logic	Apprentice rates and ratios are regulated	Does the system hold apprentice steps and flag ratio problems on site?
Native WH-347 output	An export is not a submission	Generate a signed WH-347 in front of me, not a spreadsheet.
State and local formats	Indiana agencies may require their own layout	Which additional formats ship as standard?
Union reporting	Fringe remittance and dues follow the same time data	Can union fringe reports come out of the same source?
Audit trail	The signature carries liability	Who changed a time record, when, and can I prove it?

If a vendor answers my WH-347 question by describing a report builder, I treat that as a no. You are being sold the raw material and asked to do the manufacturing.

The cost of getting it wrong

Payroll penalties are not rare. Roughly 40% of small businesses pay an IRS payroll tax penalty in a given year, averaging $850 to $1,000 per occurrence. Certified payroll adds a second exposure on top of the tax side, because prevailing wage findings can mean back wages, withheld progress payments, and in serious cases debarment from future federal work.

The cost I see hurt people most is labor. A payroll administrator spending a day a week rebuilding certified payroll reports is a real salary line, and that person is usually the only one who understands the workaround. When they leave, the knowledge leaves.

How this works in UKG Ready

Axiom is a UKG Ready Preferred Partner and Authorized Reseller, so I will be direct about where the value sits. The reason UKG Ready fits prevailing wage contractors is that time and payroll share one record. The job, the cost code, and the trade classification are captured at the clock, not stitched on afterward, which is the single thing that makes certified payroll reliable rather than reconstructive.

Configuration is the part nobody warns you about. Wage determinations, apprentice steps, fringe plans, and union rules all have to be built to match how your projects actually run. Mid-market UKG Ready implementations typically run 8 to 16 weeks, and certified payroll work sits inside that window. A platform configured by somebody who has never seen a WH-347 will produce a technically working system that still fails an audit.

That is most of what we do. Our team of 24 supports 571 client organizations, largely in construction, manufacturing, healthcare, and long-term care, in the 50 to 2,000 employee range. Pricing for a technology-only package runs $5 to $10 PEPM. Managed Payroll Services runs $30 to $50 PEPM, which is where most contractors land when they want the certified payroll produced and reviewed rather than just possible.

If you want the broader picture first, our payroll services overview covers the mechanics, and the industry pages show how the same configuration questions show up outside construction.

Frequently Asked Questions About Time, Attendance & Labor Compliance

Is certified payroll software required by law?

No. The reports are required on covered projects. Nothing obligates you to use specific software.

Does the WH-347 form have to be used?

The WH-347 is optional in form but the required information is not. Many awarding agencies expect that layout.

Can a standard payroll service handle certified payroll?

Only if every input is already correct. If time is not captured by job and classification, the report cannot be right.

How are fringe benefits shown?

As contributions to approved plans or cash paid in lieu, itemized so a reviewer can confirm the fringe portion was met.
