A five-minute tour of Prevail.

This walks you through a real book of certified payroll — a drywall subcontractor in Knoxville, ten people, two federally funded jobs, eleven weeks of history, and one week that does not add up. Open each screen and see for yourself. It takes about five minutes and you do not need to talk to anyone.

A certified payroll is not a form you fill in once the week is over. Every figure on it is load-bearing: raise a cash fringe to close a wage shortfall and you have just moved the overtime floor and the gross. The form is where the errors surface — it is not where they are made.

Log in first

One shared demo account. Nothing you do here affects anything real — the data resets every night.

  1. Start with the money that is already at risk

    The overview answers three questions: what is late, what is wrong, and what it would cost if it went out as it stands.

    Look at: $472.88 of back wages exposure across 8 findings — sitting on a payroll that has not been filed yet. That is the whole idea. The restitution figure is computed before submission rather than by an investigator two years later, when it also carries interest and a debarment conversation. Open the overview →

  2. Open the week that does not add up

    Go to Payrolls and open #7, Fort Hill Elementary Modernization. It is still a draft. Four kinds of error, eight findings — and each one is the kind that gets contractors written up rather than the kind a spell-checker finds.

    • Marisol Guerrero is $1.32/hr short on fringe. The determination asks $9.15; her plans credit $7.83, because her pension contribution is lower than the rest of the crew's. Nothing on a timesheet shows this. It is only visible if something compares each worker's actual credits against the schedule for that classification.
    • A $1.10/hr credit taken against "Tool & uniform allowance." A reimbursement is not a bona fide fringe benefit plan, so it may not be credited at all — which means every hour it was claimed on is wrong, not just the rate.
    • Overtime paid below time and a half on the basic rate.
    • Two apprentices to too few journeyworkers — and it is five findings, not one. The ratio is tested per day, not averaged over the week. A crew that comes out right on Friday was still out of ratio on Tuesday, and each day is its own violation.

  3. Now fix one of them, and watch two more appear

    Still on payroll #7. Find Marisol Guerrero's row, type 1.32 into the Cash fringe column, and save. You have just paid the shortfall in cash, which is exactly what most people would do.

    Look at: the shortfall closes — and two findings you did not have before appear. Cash paid in lieu of fringes counts toward the regular rate, so the overtime floor moved the moment you typed it; and the project gross now exceeds the week's gross for all jobs. A contribution to a bona fide plan would have done neither of those things. This is the entire argument for the product, in one keystroke: the fields are not independent of each other, and a spreadsheet has no way to know that.

  4. Then the form itself

    From the payroll, open WH-347.

    Look at: the Statement of Compliance underneath it, and the 4(a) / 4(b) / 4(c) choice — which is a legal assertion about how the fringe obligation is discharged, not a formatting preference. Print preview is laid out for letter landscape, so it comes out of the printer looking like the form the agency expects. There is also a flat-file export for the primes and agencies that want an upload rather than a PDF.

  5. Finally, what the general contractor sees

    Go to Projects, open Fort Hill Elementary Modernization, and find Reviewer link. Copy it and open it in a private window — that is what Blackwood Construction sees.

    Look at: no account and no password. They see the weeks that were actually filed, and can accept one or return it with a reason — there is a returned week in there, where Sandhu was taping on Tuesday and Wednesday while classified as a hanger, which is the one thing no engine can catch for you. Then notice what is not there: the draft with the eight findings is invisible to its own reviewer. Nothing reaches a prime until it certifies clean, and the server refuses the submit — not just the button. Open projects →

What it does not do

It is not a payroll processor: no tax filing, no direct deposit, no bank connection. It does not pull wage determinations from SAM.gov — you enter the classifications and rates per project, because they change per project and per modification. It does not import from QuickBooks, ADP or Foundation; the week is entered or pasted in. It produces the federal WH-347 and a flat file, but not state supplemental forms — California's A-1-131 and its equivalents are not in this build. There is no e-signature; you sign the certification the way you sign it today. And it cannot tell you that someone was working out of classification — if a hanger spent two days taping, only your daily reports know that, which is exactly what the returned week in the demo is about. All of it is scopeable, and I would rather you read it here than find it later.

If you want it on your own domain

$4,800 one time. No subscription. First working version in five working days.

For comparison: LCPtracker and eMars are what the prime usually mandates, they are priced per project per month on an annual contract, and the subcontractor ends up paying to feed someone else's system. This is paid once and runs on your own instance, and the reviewer portal means the prime gets a link from you rather than the other way round.

You get a perpetual licence to use and modify your instance, and a dedicated one — your data is never pooled with another customer's. Hosting and nightly backups are included for the first 30 days; after that either I keep it running for $99 a month, or I hand you the database, the source and the setup notes to run it anywhere. No lock-in either way. Reply with one question about your own payrolls and you will get a straight answer the same day, including if this is not the right fit for you.

If you run compliance for other people's payrolls

Accounting firms, payroll bureaus and labour compliance practices are buying something different: not one instance, but the whole practice on it. Same system, your branding, your client list, my name nowhere on it, and you keep the code.

$5,000 one time, white label. Not per seat, not per client.
