Full-service payroll vs payroll software

Quick comparison: who does what

Payroll in the US generally includes: calculating wages and pay dates, running pay runs, withholding payroll taxes, filing required tax forms, paying employees (often by direct deposit), and handling year-end forms like W-2s and 1099s.

Below is how “full-service payroll” and “payroll software” typically split responsibilities. Your exact included steps can vary, so you should confirm the scope in writing before you choose anything.

• Full-service payroll: A provider runs payroll for you and handles many compliance tasks (like tax filings) based on your inputs.
• Payroll software: You (or your bookkeeper) usually runs pay runs using the software, while the software helps calculate and generate filings; you still decide whether filings are submitted by you or by an add-on service.

RunWise Pay is a FREE matching service that helps small businesses connect with payroll service providers. We do not run payroll, file taxes, or give payroll/accounting/tax/legal advice.

• Confirm in writing what tax filing includes (and who is responsible) before you sign.

Option A — Full-service payroll

With full-service payroll, you send the needed information (often hours, salaries, schedules, and employee details) and the provider handles the rest—running pay calculations and pay runs, withholding, and commonly the tax filing and payments.

This option is often best when you want “someone else to handle the payroll paperwork” or when you’re new to US payroll rules. It can also help if you’re busy, have multiple employees, or don’t want to spend evenings on deadlines.

Cost usually depends on headcount, pay frequency (weekly/biweekly/semimonthly/monthly), and what’s included. As a rough range—not a quote—many small businesses see monthly costs that can start around a few dozen dollars and go higher with more employees and added features. Some providers charge a base fee plus an employee-per-month style fee; others structure differently. Always ask for a clear written breakdown.

Before you choose, verify:
1. Who files payroll tax forms and makes payments to the government.
2. What happens if a correction is needed (late payroll, wrong pay, missed deadline).
3. How support works when there’s an urgent issue before payday.

• Great fit for busy owners, teams that want fewer steps, and first-time US payroll setups.

Option B — Payroll software

Payroll software helps you run payroll yourself. It usually calculates wages and payroll taxes and can produce reports and forms. Depending on the product and setup, tax filing may require you to submit filings, or it may be offered as an additional service.

This option is often best when you (or your accountant/bookkeeper) already manage payroll processing and understand US payroll timing and compliance. It can also fit if you prefer a hands-on approach and you have consistent payroll data each pay period.

Costs vary widely. As a rough range—not a quote—software subscriptions can start at a low monthly amount and increase with add-ons, number of employees, and features like direct deposit, time tracking integration, contractor management, or year-end forms support. In some setups, you may also pay extra for filing support, deposits, or corrections.

A common risk with software is the “you are the operator” part: if you miss a deadline, enter data incorrectly, or don’t submit filings as required, the burden to fix it may land on your business.

Before you choose software, verify:
1. Who submits payroll tax filings (you vs provider add-on).
2. Whether it includes help for corrections and how those are handled.
3. The exact process for W-2s and 1099s at year-end.

When each option makes sense (no winner-take-all)

Neither option is automatically “better.” The right choice depends on your team size, pay schedule, how complex your payroll is, and how much time you want to spend managing deadlines.

Full-service often makes the most sense if:
- You want fewer steps and clearer responsibility for filings.
- You’re new to US payroll and want guided support.
- You’ve had payroll mistakes before (or worry about them) and want a provider to help fix issues.
- You need reliable support around pay dates and tax deadlines.

Payroll software often makes the most sense if:
- You (or your payroll/bookkeeping helper) will run it every cycle.
- You have steady, accurate payroll inputs and understand the rules.
- You prefer controlling the process and can manage compliance deadlines.
- You only need basic payroll tasks and want predictable tools.

Whatever you choose, confirm the “handoff points” in writing:
1. Where you provide inputs.
2. What the system/provider calculates.
3. Who submits and pays taxes.
4. How corrections are requested and processed.

• If you’re unsure, think in terms of time you want to spend vs responsibility you want others to take on.

Payroll red flags to watch for (either way)

Whether you pick full-service or software, be cautious with anything that is vague about compliance, support, or pricing. Payroll is time-sensitive and rules change by state.

Common red flags:
- Vague pricing with “surprise” fees later (ask for a full written breakdown).
- No clear statement on who files taxes and who is responsible for tax deadlines.
- No clear process for corrections when something is wrong.
- Weak or slow support right before payday.
- Pressure to sign quickly without time to review what’s included.

Also be careful with marketing that implies outcomes are guaranteed. You still need correct inputs, and tax rules depend on your state and your situation.

Best practice before you sign:
1. Ask for a written scope: what they do each pay run, what they file, and what you must do.
2. Ask for a written pricing summary: base fee, per-employee fee (if any), and any filing/correction fees.
3. Confirm the year-end process for W-2s and 1099s.
4. Confirm which state rules they support, since payroll is not one-size-fits-all.

3. Choose who to hire—staying in control of the final decision.

RunWise Pay doesn’t run payroll or file taxes, and we can’t provide tax or legal advice. For your specific deadlines and tax rules, confirm with a qualified payroll provider and/or accountant, and check current IRS and your state requirements.
