Outsourcing Payroll for Small Business: Software or Full-Service?

You already know the benefits of outsourcing payroll. Now you're choosing your path. With fewer than ten employees, that decision comes down to two options: work with a full-service firm or accountant, or use payroll software that automates calculations, filings, and deposits. Both give you a payroll operation that runs consistently.  

The cost, the control, and the level of involvement are different.

SurePayroll By Paychex is built for small business owners who want the software model done right: automated calculations, tax filings, and direct deposit. No firm required.  

What outsourcing payroll services means for a small business

Software is outsourcing. When payroll software automates your federal and state taxes, you are not doing that work. Both paths outsource payroll. The decision is which one fits your business.

Full-service outsourcing means working with a firm or accountant. You supply the data: hours worked, new hire details, any employee changes. They calculate wages, file taxes, process deposits, and handle year-end forms.

Payroll software automates the same tasks without a firm or accountant in the middle. You enter hours or approve a payroll run. The software calculates paychecks, applies withholdings, files with the IRS and state agencies, and deposits pay directly to your team. ‍

How full-service outsourcing payroll works: what it includes and what it costs

For a lean team with straightforward payroll, you typically pay more than you need with a full-service payroll provider.

This option costs $150 to $200 or more per month. A firm or accountant manages all payroll tasks: calculating wages, making tax payments on your behalf, generating pay stubs, processing direct deposit, and producing year-end tax forms: W-2s for employees and 1099-NECs for independent contractors. You supply current employee data each pay period.

Your cost increases with team size, payroll complexity, and benefits administration. Pricing covers professional expertise.

Choose full-service outsourcing if you operate across multiple states. State tax obligations are genuinely complex: different rates, different filing schedules, different rules for local tax withholdings.  

If you pay yourself a salary as an S-corporation owner, consulting with a payroll professional familiar with IRS requirements for owner compensation is a sound investment.  

If your independent contractor mix raises employee classification questions, professional insight works to your advantage.

Payroll software vs. full-service outsourcing payroll: how to choose

For a team under ten with standard payroll, an automated payroll service is the right call. With an online payroll service, you pay $40 to $80 per month: a flat base fee plus a per-employee charge.  

If you have fewer than five employees, that difference adds up to $1,000 or more per year.  

The professionals who know your business best agree. According to a 2023 SurePayroll survey, 79 percent of CPAs, bookkeepers, and financial professionals refer their small business clients to online payroll software rather than full-service firms.

You approve each payroll run, see filings as they go out, and stay on your timeline. For a small team, this usually takes under ten minutes per pay period.

‍

Small business owners spend an average of 20 hours per year just managing federal payroll taxes, according to NSBA's 2024 Small Business Taxation Survey. For a team under ten, that time rarely creates value; it's pure compliance overhead.

Payroll software changes that equation. Businesses that switch from manual methods save an average of 120 hours per year and reduce their payroll costs by up to 80 percent, according to a 2022 Paychex survey.

What to look for in a payroll software provider

Confirm six specifics before you commit. Not all payroll solutions are cost-effective for a small team, and the differences matter in ways that are not always transparent.

Automatic tax calculation and tax filing: federal, state, and local

Payroll software automates tax calculations and filing for you. Confirm that any payroll service provider you are considering covers not just federal employment tax and Social Security withholdings but also state tax and local tax filings. Some providers or plans calculate taxes but leave the tax filing to you.  

‍

Direct deposit speed

Two-day direct deposit is standard, but payroll errors and holiday-adjacent pay periods can delay paychecks. Confirm whether same-day and next-day options are available before you need them.

Real support when something does not look right

During setup and early payroll runs, you might have questions: a withholding amount that looks off, a new hire whose state tax elections need clarification. Access to a real person by phone matters.

"SurePayroll is definitely the way to go. I have had both ADP and QuickBooks in the past, but this onboarding experience has definitely been second to none." — Mark, Google review

Transparent pricing at your team size

A base monthly fee plus a per-employee fee is standard.  

Watch for costs that inflate the real payroll cost: per-run fees, year-end form fees for W-2s and 1099-NECs, and setup charges. Ask for an annual total at your current number of employees, not just the base rate.  

Support for employees and independent contractors

If you pay both employees and independent contractors, confirm the payroll system covers both on one dashboard and generates year-end W-2s and 1099-NECs automatically. Managing separate systems for the same business adds work and increases the risk of errors.

"SurePayroll is easy to set up and use. After setting up your account, you can easily run a Payroll in under 3 minutes." — Sudesna L., G2 review

Time tracking

If you pay hourly employees or track paid time off, look for integrations with your time tracking system. Entering hours manually every pay period introduces risk. The right software works with your existing setup.

SurePayroll is built for teams under ten. Employees and independent contractors in one system. Taxes filed automatically. Year-end W-2s and 1099-NECs generated on schedule. When setup raises questions, you reach a real person.

Get started with payroll software

Before you process your first pay period, gather:

•       Your EIN (Employer Identification Number), required for all payroll tax filings

•       Completed W-4s for each employee and W-9s for independent contractors

•       Bank account and routing numbers for direct deposit, yours and each employee's

•       State tax account numbers for every state where you have employees

Your payroll records and employee files have most of the information you need. If you are setting up employer payroll for the first time because you hired your first employee, register for a state tax account before you process your first payroll.

‍

Once you've set up your account and added your employees, ongoing payroll management is straightforward. You review payroll, verify hours for hourly staff, approve. The software automates withholding calculations, makes tax payments, submits filings, and completes direct deposit every pay period.

SurePayroll is built for a team your size

Your payroll operation runs on your timeline, not a firm's schedule. SurePayroll processes the calculations and filings automatically. You approve each run and keep visibility.

You see every filing before it goes out. Nothing moves without your approval.
