The real cost of DIY payroll

Running payroll in-house is a liability, not merely a task

Payroll feels like a back-office chore until the day it isn't. Here is what it quietly costs.

One mistake costs more than the time saved

A single misfiled tax deposit or blown deadline can trigger IRS and state penalties that dwarf what you thought you were saving by keeping payroll in-house.

The rules never stop changing

Wage and hour law, multi-state withholding, new local taxes. If you hire across state lines, the compliance surface grows faster than any small team can track.

Your best people are doing data entry

Every pay run your controller or office manager babysits is time not spent on the work that actually grows the business.

When something breaks, no one picks up

Big providers route you to a call center and a ticket number. A wrong paycheck erodes employee trust fast, and "we are looking into it" does not fix it.

HRO, not PEO

Outsource the work. Keep the control.

DIY software leaves you on your own. A PEO takes over your employees and locks you in. Humareso runs payroll for you while you stay fully in charge of your business.

Onboarding is the easy part

From first call to your first clean pay run

Keep your current platform or let us move you off a bad one. Most clients are live within two to three pay cycles, without a single missed paycheck.

01

We audit what you have

A payroll specialist reviews your current setup, pay schedules, tax accounts, and prior filings. You get a clear picture of risks and gaps before anything changes.

02

We take it over, on your platform

Happy with ADP or Gusto? We run it for you, no switching required. Want off a system that is failing you? We migrate you cleanly with data verification and parallel runs. Either way, mid-year is routine.

03

We run it, you approve it

Every pay run is processed and checked by your dedicated specialist. You approve in minutes. We handle deposits, filings, and year-end. You stay in control without the busywork.

FAQ

Questions we hear from owners and controllers

Straight answers. No sales pitch.

With a PEO you enter co-employment: the PEO becomes the employer of record, files under its own tax IDs, and bundles you into its plans. With Humareso HRO, you keep your own EIN, your own accounts, and full control. We run payroll for you as your partner, not your co-employer, and you only pay for the services you need.

Yes. We are platform-agnostic and run payroll on ADP, Paychex, Gusto, isolved, Paycom, Paycor, UKG, Paylocity, and more. If you like your current system, keep it. If it is the problem, we will recommend and migrate you to a better fit.

Switching mid-year is routine for us. Our implementation team verifies your data, runs parallel checks, and sunsets your old system so your year-to-date totals and filings stay clean. Most clients move without a single missed or incorrect paycheck.

Yes. We handle federal, state, and local tax deposits and filings, including multi-state withholding for distributed teams, plus year-end W-2 and 1099 processing. Keeping up with changing wage, hour, and tax rules is our job, not yours.

We process complex pay structures every day: tip credits and tip reporting for restaurants, commission and spiff plans for dealerships, shift differentials for healthcare, and bonus or equity events for startups. If it can be paid, we can run it correctly.

You get a dedicated payroll specialist who knows your account by name, with a named backup so coverage never lapses. No ticket queue, no starting over with a new rep every time you call. That responsiveness is the main reason clients leave the big providers for us.

Pricing is scoped to your headcount, pay frequency, and complexity, and you only pay for the services you turn on, with no long-term contract. Tell us about your business and we will send a tailored quote, usually within one business day.

Most clients are live within two to three pay cycles. We audit your current setup, verify and import your data, run a parallel check, and then take over. Switching mid-year is routine; your year-to-date totals and filings stay clean.

Payroll data is encrypted in transit and at rest, with strict role-based access controls and audit logging. Your data stays yours and is never sold. (Ask us about our current security certifications and we will share details for your review.)

Yes. For construction and trades we handle Davis-Bacon certified payroll, prevailing-wage rates, union fringe tracking, and job-cost-ready reporting. If your work involves public contracts or union agreements, tell us the details and we will scope it.

That is the point. Payroll is often the first step. Our award-winning HRO plan and consulting services let you add benefits administration, leave management, compliance, and recruiting whenever you are ready, with the same team that already knows your business.

Payroll should be the part you never worry about.

Tell us your headcount and current setup. We will show you exactly what working with us looks like and what it costs, usually within one business day. No pressure, no obligation.

You keep full control of your company. We just make payroll disappear from your to-do list.
