The Cost of Payroll Outsourcing

Outsourcing payroll trades dollars for time, headache, and tax-penalty risk. The question is what those dollars actually look like once the contract is signed and a year of paychecks have run. The simple answer for most small service businesses today is $80 to $250 a month for a full-service plan covering 10 to 25 employees, but the spread inside that range depends on the provider, the plan, and a stack of add-ons that do not show up on the headline price.

Here is the current pricing landscape, what is actually included at the headline rate, what gets added on, and the math that decides whether outsourcing is worth it for your shop.

Pricing Models

Most modern payroll providers price the same way: a monthly base fee plus a per-employee fee. Industry-standard ranges:

• Base fee: $17 to $80 per month for the lower tiers, $80 to $150 per month for the higher tiers with HR or benefits added.
• Per-employee fee: $4 to $12 per active employee per month.
• Contractors: usually $4 to $6 per active 1099 contractor per month, billed only for months the contractor is paid.

A 10-employee shop on a mid-tier plan runs about $100 to $150 a month. A 25-employee shop runs about $200 to $300 a month. The math gets less favorable as you scale because the per-employee fee compounds.

Provider Picks

Six providers cover most of the small-and-mid service business market:

• Gusto. The default modern pick for service businesses under 50 employees. Simple plan structure, transparent pricing, strong benefits and HR add-ons. Around $40 base plus $6 to $12 per employee depending on tier.
• QuickBooks Payroll. The natural pick for shops already running QuickBooks for accounting. Three tiers from Core ($45 + $6 per employee) up to Elite ($125 + $10 per employee). Tight integration is the main reason to pick it.
• OnPay. The all-inclusive single-tier option at $40 base plus $6 per employee. No upcharges for multi-state, benefits administration, or year-end forms. A favorite for owners who hate add-on math.
• ADP RUN. The legacy enterprise name available for small business. Custom-quote pricing, typically higher than Gusto or OnPay at the same headcount. Worth considering if you also want bundled benefits administration and HR consulting.
• Paychex Flex. Similar profile to ADP RUN, custom-quote pricing, mid-market and enterprise leaning. Strong for shops that anticipate scaling past 50 employees.
• Rippling. The newer all-in-one HR, payroll, IT, and benefits platform. Per-employee-only pricing starting around $8 plus modules. Best for tech-forward shops that want one console for everything.

Square Payroll at $35 base plus $6 per employee is a respectable seventh option for shops that already run Square for point-of-sale.

What's Included

The headline price for most providers covers:

• Paycheck calculation, federal and state tax withholding, and tax filing.
• Direct deposit to employee bank accounts.
• Employee self-service portal for pay stubs, W-2s, and benefit enrollment.
• New-hire reporting to state workforce agencies.
• Year-end W-2 and 1099 generation.
• Standard customer support during business hours.

Direct deposit fees, which the original generation of payroll services charged per paycheck, are now bundled into the base plan at almost every provider. If a salesperson tries to add per-paycheck direct deposit fees, walk.

Hidden Costs

The headline price is not the bill. The line items that quietly add up:

• Multi-state payroll. An extra fee per additional state, usually $10 to $25 per state per month. Real for service shops that cross state lines.
• Year-end forms. Some providers charge $5 to $15 per W-2 or 1099 mailed. Others bundle it.
• Time tracking. A separate module at most providers, $4 to $10 per employee per month on top of payroll.
• Benefits administration. $4 to $8 per employee per month, on top of the actual benefit premiums.
• Garnishments and child-support orders. Sometimes free, sometimes $5 to $10 per garnishment per pay period.
• Off-cycle payroll runs. Bonus payments, corrections, and final paychecks outside the regular schedule. Often $10 to $25 per off-cycle run.
• Setup fees. One-time charges that range from waived to $200, depending on provider and how hard you negotiate.

Get every one of these on the quote before you sign. A "$60 a month" plan can become $300 a month with three add-ons that did not feel optional.

When to Outsource

The honest math, for a service business:

• Under 5 employees. Doing payroll yourself in QuickBooks Online with the basic payroll add-on works fine and runs about $50 to $75 a month total. Outsourcing is more peace of mind than time savings.
• 5 to 25 employees. The sweet spot for outsourcing. The cost is small, the time savings are real, and the IRS-penalty insurance starts to actually mean something. The IRS estimates that around one-third of small businesses pay a payroll-related penalty in any given year. The cheapest way to never be one of them is to outsource.
• 25-plus employees. The scale at which the per-employee fee becomes the larger line item. Worth pricing both outsourced and bringing payroll in-house with a dedicated person, especially if you also have HR needs that the same person can absorb.

The other variable is your time. If running payroll takes the owner four hours a week, outsourcing buys back 200 hours a year. If those 200 hours go into chasing bigger jobs, the outsourcing fee pays for itself many times over.

Wrapping Up

Outsourced payroll is mostly a solved category today. The pricing is transparent enough, the providers are stable enough, and the time savings are real enough that the question for most service shops is which provider, not whether. Pick on integration with your accounting software, all-inclusive pricing if you can find it, and a contract that does not punish you for changing later.
