Three payroll paths exist for a small employer, and the invoice is the least useful way to compare the three. Handling payroll inside the business looks free until owner hours, deposit deadlines, and worker classification get priced honestly. A payroll service converts most of that work into a predictable monthly fee, while a professional employer organization goes further by sharing employer-of-record status and bundling human resources support, compliance help, and pooled benefits access. In Clark County the comparison tilts harder than the national version, because Nevada prohibits applying tips as a credit toward the minimum wage and most national payroll templates assume the opposite. The path that fits at nine employees is frequently the wrong path at twenty five.

Quick Answer

In-house payroll carries no vendor invoice but consumes owner hours every pay period and concentrates deposit, filing, and worker-classification exposure on one person.
A payroll service charges a monthly base fee plus a per-employee fee and removes most filing and deposit work, while wage policy and worker classification stay with the business.
A PEO uses co-employment to become the employer of record for payroll tax and benefits purposes, which pools many small employers and can reach benefits pricing a single small business cannot.
Las Vegas raises the stakes on the in-house path, because Nevada prohibits applying tips as a credit toward the minimum wage and operates a two-tier minimum wage structure.
The right answer moves with headcount and belongs on a re-run at every growth stage rather than treated as a permanent decision.

Every payroll decision is a bet about what an owner’s time is worth and how expensive a mistake will be. The invoice is the visible part, and it is the least interesting number on the page.

The comparison that decides whether a business is quietly bleeding includes the hours, the exposure, and the recruiting weight of benefits. Here is the whole board.

What does each payroll path actually cost?

Three costs exist on every path: the fee, the owner hours, and the exposure. Only the first one arrives as a bill, and it is usually the smallest of the three.

	In house	Payroll service	PEO
Visible cost	Software subscription, often minimal	Monthly base fee plus per-employee fee	Percentage of payroll or flat per-employee-per-month, highest
Owner hours	Hours every pay period	Minutes	Minutes
Tax filings and deposits	Owner’s responsibility	Included	Included
HR policy and handbook	Owner’s responsibility	Owner’s responsibility	Substantially covered
Worker classification	Owner’s responsibility	Owner’s responsibility	Shared, with guidance
Benefits access	Whatever a small group can reach	Whatever a small group can reach	Pooled across the PEO client base
Workers’ compensation	Sourced separately	Sourced separately	Frequently bundled
Error and penalty exposure	Highest	Low on filings, unchanged on policy	Lowest overall
Exit friction	None	Low	Real, since employer of record changes back

The in-house row deserves its own paragraph. Payroll penalties are not exotic and they are not reserved for careless operators. Late deposits, misclassified workers, and inaccurate tip reporting are the ordinary failure modes of a busy owner running payroll at 11pm on a Sunday. The IRS publishes its employer guidance on the health care law and related employer obligations for exactly the businesses that assume none of it applies to them. Free payroll that produces one penalty notice and consumes four owner hours a month is among the most expensive products a small business can buy.

What is a payroll service actually removing?

A payroll service removes the calculation, the deposit, and the filing calendar. It does not remove judgment calls, and judgment calls are where most real money is lost.

The division is cleaner than most owners expect. The service takes hours in and produces accurate paychecks, correct withholding, on-time deposits, and quarterly and annual filings. That is a genuine transfer of work and it happens at a predictable monthly cost that scales with headcount.

What stays behind is everything upstream of the data. Whether a worker is an employee or a contractor. Whether a role is exempt or non-exempt. Whether overtime was calculated on the correct regular rate once a nondiscretionary bonus is in the mix. Whether tips were reported before they were withheld on. A payroll service files precisely what it is given, which means bad inputs produce clean, timely, wrong filings.

There is a timing dimension too. A payroll service compresses the work but does not eliminate the calendar, and deposit deadlines still arrive whether or not the hours got approved on time. An owner who submits late is buying an on-time filing with bad data, which is the least useful combination available. The habit that separates a smooth payroll from a fragile one is closing the pay period a day early rather than at the deadline, and no vendor can install that habit for a business.

For a business with salaried office staff and no tipped employees, that residual risk is small and a payroll service is usually the correct answer. For a business with tipped staff, seasonal surges, or a mix of employees and contractors, the residual is the whole problem. The threshold question is worked through in when should a business outsource payroll.

What is a PEO really selling?

A PEO sells pooling, and co-employment is the mechanism that makes pooling legally possible. The employer of record for tax and benefits purposes changes; control of the business does not.

Under co-employment, the professional employer organization becomes the employer of record for payroll tax and benefits purposes while the owner keeps complete control of hiring, firing, scheduling, pricing, and every operational decision. The structure is explained more fully in what is co-employment.

What that unlocks is scale a nine-person Las Vegas company cannot manufacture on its own. Inside a PEO, that nine-person business buys as part of a client base numbering in the tens of thousands. Health plans, workers’ compensation rates, and retirement options that no nine-person group qualifies for alone start pricing like something a much larger employer would get.

The honest caveat

The bundle costs real money, and a business that does not need the HR layer or the benefits story is paying for shelf space it will never walk into. A PEO priced as a percentage of total payroll also scales in a direction that is not always intuitive: as average wages rise, the fee rises with them whether or not the service consumed rose too. Pricing structures are broken out in how much does a PEO cost, and the full scope of what a PEO handles is in what does a PEO do.

Exit deserves more attention than it gets during the sales process. Leaving a PEO means re-establishing state accounts, re-sourcing benefits, and moving employees onto plans that will not be priced the way the pooled plans were. It is entirely doable and it is not a weekend project. The mechanics are covered in can a business leave a PEO.

How does the answer change as a business grows?

Under roughly five employees with simple payroll, in-house or a low-cost service is usually rational. Past that, the error rate and the owner-hour cost start climbing faster than headcount does.

From five to about fifteen employees, particularly with tipped staff, contractors, or the first real benefits conversation, two things happen at once. The in-house path gets meaningfully worse, because the number of distinct rules in play multiplies. And the PEO math gets meaningfully better, because benefits access starts carrying recruiting weight the business can actually feel. What that benefits weight is worth is the subject of the small business benefits playbook.

Past fifteen, the paths diverge by strategy rather than size. Some businesses stay in a PEO indefinitely for the benefits leverage. Others build an in-house HR function with a payroll service underneath it and reclaim the margin. Neither is wrong. The signals that a business has outgrown its current setup are listed in the HR warning signs checklist, and the tasks most commonly handed off first are in what HR tasks can be outsourced.

The pattern worth internalizing: this decision is not permanent, and re-running it at every growth stage is the actual best practice. Most businesses that end up badly served did not choose wrong. They chose correctly in year two and never revisited it in year six.

There is also a version of this decision that gets made by default, which is the worst version. An owner who has never priced the alternatives is not running payroll in house because in-house payroll fits the business. That owner is running payroll in house because switching requires an afternoon nobody has scheduled. The cost of that afternoon has been paid several times over by the time anyone counts it.

Why is the Las Vegas version of this comparison different?

Nevada prohibits a tip credit. An employer may not apply tips as a credit toward payment of the minimum wage, and Nevada operates a two-tier minimum wage structure. That one rule breaks most national payroll setups.

Almost every payroll template, franchise handbook, and piece of national small-business advice assumes tipped employees can be paid a reduced cash wage with tips making up the difference. The Department of Labor maintains a state-by-state table of minimum wages for tipped employees showing which states permit that and which do not, and its fact sheet on tipped employees under the FLSA covers the federal framework. In Nevada, a setup built on tip-credit math is wrong from the first paycheck, and back-wage exposure compounds every pay period it runs uncorrected.

Layer on tip reporting, which the IRS covers in its tip recordkeeping and reporting guidance, plus the service-charge distinction that catches banquet and convention operators constantly, and the in-house row of that table gets materially worse in this valley than it does nationally. The specific failure modes are catalogued in tipped payroll mistakes Las Vegas businesses keep making.

Nevada does have one simplifying feature worth naming. There is no state income tax, so the withholding stack is shorter here than in most states. That is real, and it is not enough to offset a tip-credit error.

An illustrative example

Consider an eighteen-person banquet and event staffing company off Paradise Road. Twelve tipped event staff, four kitchen, two in the office. Headcount swings by fifty percent between a heavy convention month and a quiet one, and the owner runs payroll personally on Sunday nights.

Using illustrative figures only, call it five hours per pay period across data entry, corrections, deposits, and chasing down missing tip reports. At twice-monthly payroll, that is roughly 120 hours a year. Price the owner’s time at whatever the next hour of sales work is worth to that business and the in-house path is already not free, before a single error.

Now add the variable that only exists in a business like this one: service charges on banquet contracts are not tips, and coding them as tips changes withholding, overtime math, and credit eligibility all at once. One misconfigured earnings code repeated across a convention season is not a rounding error. That is the exposure a fee schedule never shows.

The hours and the framing above are invented to illustrate the shape of the decision, not measurements of any real business.

What questions decide this, once the logos are gone?

Four, and each one has a number attached that most owners have never calculated.

How many owner hours per month does payroll currently consume, priced at what that time earns elsewhere? Not what the owner pays themselves. What the next hour of selling, hiring, or operating is worth.

What did errors, penalty notices, corrections, and near-misses cost over the last two years? Including the amended filings nobody counted as a cost because they were fixed quietly.

Is benefits access part of the next hiring push? If two open roles have gone unfilled for four months, the benefits leverage inside a PEO stops being an abstraction. The broader landscape is in the small business health insurance guide, and the size thresholds that determine what is even available sit in how many employees are needed for group health insurance.

What does the workforce look like in eighteen months? A business heading from nine to twenty five people is answering a different question than one that has been stable at nine for six years.

A business that answers all four honestly has usually already made the decision. The decision framework in the ProtectHealth buyer’s guide walks the same ground with the benefits side attached.

We are insurance nerds, not tax professionals. Payroll tax exposure, credit eligibility, and worker classification all carry tax consequences, and a licensed tax professional belongs in the room before any of those get restructured. Anyone taking insurance advice in this state can verify a producer license through the Nevada Division of Insurance first.

The product should serve the strategy, not become the strategy. A PEO is not a status upgrade and in-house payroll is not discipline. Both are tools, and the one that fits is whichever one buys back the hours and the exposure a specific business cannot currently absorb.

Frequently Asked Questions

What does a payroll service typically charge?

Payroll services generally bill a monthly base fee plus a per-employee fee, with tax filing, deposits, and direct deposit included. Pricing scales with headcount and with add-ons such as time tracking, benefits administration, or multi-state filing, so a quote depends on the roster rather than on a published rate.

What is co-employment in a PEO relationship?

Co-employment means a professional employer organization becomes the employer of record for payroll tax and benefits purposes while the business keeps full control of hiring, scheduling, supervision, and daily operations. That shared status is the mechanism that lets a PEO pool many small employers for insurance and benefits pricing.

At what headcount does in-house payroll stop making sense?

Strain usually appears past roughly five employees and multiplies with tipped staff, contractors, multi-state workers, or a first benefits offering. The trigger is more often a specific event, such as a penalty notice or a hiring push, than a headcount number on a chart.

Does outsourcing payroll remove employer liability?

Not entirely. A payroll service files and deposits based on the data supplied, so worker classification, wage and hour policy, and recordkeeping remain the employer's responsibility. A PEO absorbs a larger share of that work through co-employment, though core employer obligations still sit with the business.

Why does Las Vegas change the payroll comparison?

Nevada prohibits a tip credit, so tipped employees receive the full applicable minimum wage in direct wages before tips, and Nevada operates a two-tier minimum wage structure. National payroll templates built on the federal tipped cash wage produce back-wage exposure in Nevada from the first pay period.
