Payroll Services vs. DIY: An Honest Cost Comparison for Houston Small Businesses

A solo plumber in Katy ran his own payroll for four years with a single W-2 employee (his nephew) using a spreadsheet and an accountant he called once a year. His annual payroll tax cost outside of wages: about $3,100. His time investment: roughly two hours per biweekly pay period, 26 periods, 52 hours per year.

At his billable rate of $95 per hour, those 52 hours represent $4,940 in potential service revenue he spent doing payroll instead. He was paying a hidden cost of $4,940 to avoid a $75/month service.

He didn’t see it that way until we laid it out on a whiteboard.

That’s not an argument that everyone should outsource payroll. It’s an argument for actually running the numbers before deciding.

The DIY Payroll Stack

When you run payroll yourself, your costs fall into three categories: software, your time, and penalties.

Payroll software. Most small business payroll software runs between $30 and $100 per month. QuickBooks Payroll Core starts at about $50/month plus $6 per employee. Gusto Simple starts at $40/month plus $6 per employee. These prices cover the software but not your time.

On a team of three employees, QuickBooks Payroll Core costs about $68/month, or $816 per year.

Your time. This is the cost nobody writes down. Running payroll for three hourly employees with varying hours takes about 90 minutes per pay period when you include collecting hours, verifying calculations, submitting direct deposit, and confirming EFTPS deposit. On a biweekly schedule: 26 periods x 90 minutes = 39 hours per year.

If your time is worth $50 per hour (a conservative figure for a business owner), that’s $1,950 per year in time cost.

Penalties. If you make mistakes, miss deposits, or miscalculate withholdings, you absorb the penalties. These aren’t theoretical. IRS late deposit penalties run from 2% to 15% per occurrence. One missed quarter can cost more than a year of payroll service fees. See our breakdown of Texas-specific payroll tax penalties for the full picture.

Your DIY total for 3 employees (biweekly):

• Software: $816/year
• Your time (39 hours at $50/hr): $1,950/year
• Penalty risk: variable (one miss can cost $300-$3,000+)

The Outsourced Payroll Stack

A Houston payroll service like EZQ Group for three employees runs $75/month flat, $900/year. That covers every step: collecting hours from you, calculating pay, running direct deposit, making EFTPS deposits, filing Form 941 quarterly, submitting the TWC wage report, and producing W-2s at year-end.

Your time per pay period: about 15 minutes to review and approve.

On a biweekly schedule: 26 periods x 15 minutes = 6.5 hours per year.

Outsourced total for 3 employees (biweekly):

• Service fee: $900/year
• Your time (6.5 hours at $50/hr): $325/year
• Total: $1,225/year

DIY total for comparison: $2,766/year (before any penalties)

The payroll service costs $1,541 less per year than DIY at this scale, once time is factored in.

Where DIY Actually Makes Sense

The plumber’s situation was real, but it was also relatively simple: one employee, fixed salary, no overtime, no tipped wages, no varying hours. Here’s when DIY payroll can work:

One employee on a fixed salary. No overtime calculations. No varying hours. The FICA, federal withholding, and EFTPS deposit are the same every period. If you’re careful and disciplined about the EFTPS deadline, a fixed-salary sole employee is DIY-manageable.

You have an accounting background or run your own books closely. Business owners who already reconcile their books monthly and understand tax deposits have the foundation to run payroll without missing the pieces. The issue isn’t complexity; it’s knowing what the pieces are.

You’re in the first three months of hiring. When you first bring on employees, doing one or two payroll runs yourself can teach you the process. Once you understand what a payroll service is doing, you’re better positioned to verify their work.

Where DIY Stops Making Sense

Three or more employees with hourly pay. Overtime calculations multiply your error surface. Miscalculating one week of overtime for three employees means three corrected checks or three adjustments next period. The calculation time goes up faster than the employee count.

Tipped employees. Restaurant and bar staff in Houston require tip reporting, allocated tip calculations, and FICA tip credits. These create additional IRS forms (Form 8846) and require precise tracking to claim the credit. DIY payroll software handles this but requires setup knowledge most business owners don’t have.

Contractors mixed with W-2 employees. If you have some employees and some 1099 contractors, payroll gets more complex. Worker classification becomes a live question. Any misclassification discovered later creates back taxes across all affected periods.

You’ve already missed a deposit. Once you’re behind, catching up creates reconciliation issues on Form 941. Getting current requires understanding the penalty abatement process. At that point, professional help pays for itself in the first interaction.

The Real Comparison Table

Scenario	DIY Annual Cost (time + software)	EZQ Payroll Annual Cost	Difference
1 salaried employee	$650	$900	-$250 (DIY cheaper)
3 employees (biweekly)	$2,766	$900	+$1,866 (service cheaper)
5 employees (biweekly)	$3,900	$1,380	+$2,520 (service cheaper)
10 employees (biweekly)	$6,500	$1,800	+$4,700 (service cheaper)

Time valued at $50/hour. DIY includes software at $68-$100/month depending on employee count. Service pricing based on EZQ Group flat rates.

The crossover point is around two employees for most Houston businesses. One employee with fixed pay: DIY has a case. Two employees with variable hours: the math already favors a service.

What the Numbers Don’t Show

The table above doesn’t capture three things that matter:

Penalty risk. One missed EFTPS deposit at $5,000/month costs $250-$750 in penalties. One missed Form 941 filing costs more. One worker misclassification discovered in an audit costs years of back taxes. The penalty risk isn’t a given, but it’s real and asymmetric: it only flows in one direction.

The cost of switching mid-mess. Businesses that hire us after accumulating penalties spend two to three times more in cleanup than they would have spent on prevention. The IRS penalty abatement process is available, but not guaranteed, and it requires documentation.

What you do with the time. The plumber’s 52 hours per year converted directly to service revenue. A restaurant owner’s 52 hours per year might mean time with their family, better vendor relationships, or simply less stress during an already demanding week.
