What Should Payroll Really Cost for a Construction Company? A Transparent Breakdown

Payroll pricing for a construction company is generally driven by a handful of factors: how many employees you have, whether you need ITIN worker processing, whether you're adding time and attendance, and whether you want HR support or an employee handbook. As a real example: a 10-employee construction company adding 3 ITIN workers and time and attendance, with no HR Experts or handbook, might land around $116–$139 per payroll for payroll processing and $16–$19 per payroll for time and attendance, with one-time implementation fees and a first-year total in the range of $1,500 before settling into a lower ongoing monthly cost. Actual pricing depends entirely on your specific setup, which is why it's worth running your own numbers rather than relying on an industry-wide average.

Why Payroll Pricing Feels Like a Black Box

Ask most construction owners what they actually pay for payroll, and you'll get a rough guess, not a real number. Not because owners aren't paying attention — because payroll pricing is often deliberately hard to pin down. Line items on an invoice can shift month to month. New fees get added quietly. And when you call to ask why the bill went up, the answer isn't always straightforward.

That vagueness isn't an accident in every case. Some providers rely on it. If you don't know what a fair price looks like, you don't know when you're being overcharged.

What Actually Drives Your Payroll Cost

Rather than a flat, one-size-fits-all price, payroll cost is generally shaped by a specific set of factors:

• Number of employees — the core driver of your ongoing per-payroll fee
• ITIN workers being added — since processing workers without a Social Security Number involves additional setup
• Time & attendance — whether you need digital time tracking, and how many physical clocks (if any) across your job sites
• HR Experts support — handbooks, compliance guidance, and policy documents, priced as an annual fee if added
• Employee handbook — whether one needs to be created or maintained
• Overtime — whether your crew regularly works overtime, which can affect calculation complexity
• Payroll frequency — how often you run payroll

A Real Example

Here's an actual estimate, pulled directly from Baron's Instant Price calculator, for a construction company with:

• 10 employees
• 3 ITIN workers being added
• Time & Attendance: yes
• HR Experts: no
• Employee handbook: no
• No regular overtime
• 0 physical time clocks
  
  

Notice how much of the first-year cost is front-loaded into one-time implementation and training — and how the ongoing monthly cost afterward drops significantly. This is a common pattern worth watching for when comparing quotes: a provider that only shows you an ongoing monthly number, without the first-year implementation costs, isn't giving you the full picture.

Your own numbers will differ based on headcount, ITIN workers, whether you need physical clocks, and whether you add HR Experts or a handbook — which is exactly why running your specific setup through a calculator matters more than any industry-wide average.

The Fees That Tend to Catch Owners Off Guard

A few costs that might not show up clearly on an initial quote, but tend to appear later:

• Setup or implementation fees when first switching providers
• Year-end filing fees charged separately from the regular per-payroll cost, often billed as a surprise in December or January
• "Support" fees for phone or email assistance beyond a basic tier
• Off-cycle payroll run fees if you need to issue an off-schedule check or correction
• Price increases tied to headcount changes that aren't clearly explained when a seasonal crew grows or shrinks

None of these are automatically unreasonable on their own. The issue is when they're not disclosed clearly upfront, so an owner has no way to compare providers on an apples-to-apples basis.

How to Actually Evaluate a Payroll Quote

A few questions worth asking any current or prospective provider directly:

1. "What's included in the base fee, and what's billed separately?"
2. "Is there a fee to add or remove employees during the year, especially for seasonal hires?"
3. "Are year-end tax filings included, or billed as a separate charge?"
4. "If I need to run an off-cycle payroll, what does that cost?"
5. "Can you add ITIN workers to payroll, and is there an additional charge for that?"

If a provider can't answer these clearly and immediately, that's worth treating as useful information on its own.

Frequently Asked Questions

How much does payroll typically cost for a small construction company? It depends heavily on headcount and which services you add. As one real example, a 10-employee construction company adding ITIN workers and time and attendance landed around $1,500 for the first year (including one-time implementation) and roughly $80 a month ongoing after that — but your own number could look different depending on your setup.

Why is the first-year cost higher than the ongoing monthly cost? Implementation and training are typically one-time fees charged in year one to get your payroll and time and attendance systems set up correctly. Once that's done, the ongoing monthly cost reflects only the recurring per-payroll fees going forward — which is why comparing quotes based on "monthly cost" alone can be misleading if implementation fees aren't factored in.

Does adding ITIN workers or time and attendance increase the cost? Yes, both are typically priced as add-ons to the base payroll fee, since each involves additional setup and ongoing processing. The specific increase depends on how many ITIN workers you're adding and whether you need physical time clocks in addition to digital tracking.

Does adding seasonal workers significantly increase payroll costs? It can, since pricing is generally tied to active employee count — which is why it's worth understanding upfront how a provider handles pricing during seasonal headcount changes rather than being surprised by it later.
