A thread on r/smallbusiness this week started with a simple question: "What payroll software are you actually using and do you like it?"
By the time it finished, it had turned into something more useful than a software review. Owner after owner started doing the math - and the number that kept coming up wasn't the subscription fee. It was the time.
Here's what emerged: for small businesses running payroll manually, the administrative overhead - fixing timesheets, catching overtime errors, dealing with PTO miscalculations, handling one-off corrections - runs about 5-7% of total payroll. The software subscription is almost an afterthought.
What That Looks Like in Real Numbers
If you have 4 employees averaging $3,500/month each, your payroll is $14,000/month.
Five percent of that is $700.
If your payroll software costs $80/month, the total you're actually spending - including the time you or your manager spends wrangling errors - is closer to $780. Every month. For four people.
Scale that up to 10 employees at the same average, and the hidden overhead reaches $1,400+ a month. That's before you've processed a single invoice or taken a single meeting.
Where the Hidden Cost Actually Lives
People in the thread broke it down into four buckets:
1. Timesheet corrections. The most common culprit. An employee clocks in wrong. Someone forgets to punch out. You catch it two pay periods later. Fixing it takes time you didn't budget.
2. Overtime miscalculations. Particularly painful for hourly workers. One missed calculation - especially in states with daily overtime rules, like California - can trigger a correction that ripples backward.
3. PTO tracking errors. Accruals that don't match what employees think they have. Arguments about rollover. "I thought I had 3 days left." The back-and-forth is rarely 10 minutes.
4. State tax filings. If you have employees in more than one state, even just one remote worker, payroll complexity roughly doubles. Several owners in the thread said they didn't realize they needed to register in a second state until they got a notice.
The Software People Are Actually Switching To
Gusto came up more than any other tool. The recurring praise wasn't about features - it was about state tax handling. Owners who moved from ADP or QuickBooks Payroll said Gusto "just handles it" in a way that eliminated most of the correction cycles.
OnPay was a close second for price-sensitive owners - around $6 per employee per month on top of a $40 base, which for a 4-person team works out to $64/month. Less automation than Gusto, but cleaner reporting.
ADP Run kept coming up in complaints, specifically around customer service when something went wrong and incorrect state tax filings that the software filed without flagging the error.
The Real Question to Ask Before You Switch Tools
Don't ask "What does this software cost?"
Ask: "How does this software handle errors, and what happens when it makes one?"
That's where the hidden 5-7% either stays or goes away. A tool that proactively flags overtime anomalies before you process is worth more than one that files state taxes correctly 98% of the time.
One Quick Win If You're Not Ready to Switch
Set a recurring 15-minute calendar block the Friday before every pay period. Not to process payroll - just to audit it. Run through timesheets. Cross-check PTO. Look for anything unusual.
Owners who do this consistently report catching 80-90% of errors before they hit. The 5-7% overhead shrinks substantially when you catch mistakes before you have to correct them retroactively.
