Overview: Payroll Services
Payroll is the one back-office job where a mistake shows up immediately and personally. Somebody's pay is short. A deduction was missed. A deposit went in late and the notice turns up weeks later with interest attached. Payroll companies exist because the arithmetic is simple and the compliance wrapped around it is not.
The service usually covers the pay cycle itself, withholding calculations, tax deposits, the filings that follow, new hires and terminations, year-end forms, and record keeping. Timekeeping normally sits beside it, since hours are where most errors begin. Garnishments, benefit deductions and employees working across state lines are the extras that separate one quote from another.
Ask three questions before signing. Who carries the cost if a filing is late or wrong, and will the provider pay the penalty? What happens at year end, and is it inside the fee? How do you get your data out if you leave? Then ask about support, because a named contact against an anonymous ticket queue is what clients complain about most.
Each listing reflects what a company publishes about its services, the systems it runs and the industries it serves. The state and city lists lead to providers near you, and each city page shows which are based in that city.
What does payroll service cost?
Compare full payroll processing with tax filing, using the same headcount. These monthly examples assume 10 paid employees in one state at regular, non-promotional prices. You may still need to enter hours and approve payroll.
| Service or situation | Estimated cost or fee basis | Scope and conditions |
|---|---|---|
| Payroll platform with tax filing: 10 employees | $87–$109/month | Monthly plans with unlimited payroll runs and year-end tax forms. Wages, employer payroll taxes and benefits premiums are separate. |
| Payroll platform plus time tracking: 10 employees | $113–$169/month total | The same headcount with integrated employee time tracking. This is a package total, not a charge to add to the first row. |
| Payroll run for you by a service team | Monthly or per-run quote | Agree who enters data, handles changes and responds to notices. Per-run pricing makes pay frequency part of the annual cost. |
| Setup and historical payroll transfer | Included in some plans; otherwise separately quoted | Confirm employee setup, year-to-date balances, state accounts and transition work. Fixing old filing errors may be a separate engagement. |

Ask before hiring
What is the first-year total at our headcount and pay schedule, and who is responsible for submitting, approving and correcting payroll?
Weekly payroll does not itself raise an unlimited-run monthly fee. It can increase the bill under per-run pricing.
Frequently asked questions
What does a payroll company actually handle?
The pay cycle, withholding and employer taxes, the deposits, the periodic and annual filings, new hires and terminations, garnishments, benefit deductions and year-end forms for your staff. Most also provide employee self-service and timekeeping. Human resources advice, benefits brokerage and employment law are separate services even when the same company sells them.
Who is liable if a payroll filing goes in late?
You are, in the eyes of the tax authority, because the employer remains responsible for its own filings. Many providers offer a guarantee that covers penalties caused by their error, but the wording varies and some exclude anything traced back to data you supplied late. Read that clause before you sign, not afterward.
How are payroll services usually priced?
Usually one of two ways: a monthly base fee plus an amount per employee, often with unlimited pay runs, or a charge per pay run plus an amount per employee. Under per-run pricing, paying weekly costs more than paying twice a month for the same headcount; under an unlimited-run plan it may cost the same. Year-end forms, garnishments and additional states are often billed separately. Ask what is excluded, what happens when you hire, and whether implementation carries a one-off charge.
Do we need timekeeping as well as payroll?
If you pay hourly staff, overtime or shift differentials, yes, and integrating the two removes the rekeying that causes most errors. Salaried offices with fixed hours often manage without it. The audit trail matters too: when someone disputes their pay, an approved timesheet settles it quickly.
What should we ask before switching payroll providers?
Where the historical data goes and in what format, whether year-to-date figures transfer correctly, who handles filings for the part-year already run, whether parallel runs are included, and what the implementation timetable looks like. Switch at the start of a quarter or a year if you can. Mid-year moves are the ones that go wrong.
