5 Costly Payroll Mistakes SMEs Make (and How to Avoid Them)

If you're running an SME, you're probably used to spinning a lot of plates managing people, keeping customers happy, and staying on top of cash flow, all while making sure everyone gets paid correctly and on time. 

Payroll might seem like a straightforward process. After all, it’s just calculating wages and paying Revenue, right? But in reality, it’s one of those things that seems simple until it suddenly isn’t. 

We've seen it time and again: small mistakes in payroll can snowball into major problems, affecting everything from employee morale to your bottom line. The good news? Most of these mistakes are avoidable if you know what to look out for. 

 

1. Paying Employees Late (Even by a Day) 

It happens - someone’s off sick, the system crashes, or the person who runs payroll is on annual leave. But for your team, a late wage packet isn’t just a hiccup. It can lead to missed bills, unnecessary stress, and a breakdown in trust. And if it becomes a pattern? You could lose great people. 

 

2. Getting Tax or PRSI Calculations Wrong 

Irish payroll is no stranger to complexity. With PAYE Modernisation, pensions, BIK, and ever-changing thresholds, even the most diligent in-house team can make a mistake. Unfortunately, Revenue won’t always take a kind view - errors here can lead to interest, penalties, and audits. 

 

3. Misclassifying Workers 

Hiring a contractor when they really should be an employee (or vice versa) is a surprisingly common slip-up. It may seem harmless, but getting it wrong could land you with a tax liability, not to mention back payments. If you’re scaling or using flexible staffing, this is one to watch. 

 

4. Relying on Spreadsheets or Manual Processes 

We’re big fans of Excel for lots of things - but running payroll on a spreadsheet? That’s a risky game. One wrong formula or missed cell and you’ve got a problem on your hands. Manual processes are also more time-consuming and leave little room for scalability. 

 

5. Choosing a Provider That’s Not Right for You 

Sometimes the biggest mistake is picking a payroll provider that doesn’t actually fit your business. Maybe they’re too rigid, too expensive, or just not familiar with Irish legislation. You might end up spending even more time on payroll this way, just in managing the service. 

 

The Fix? Start Asking the Right Questions 

If any of the above sounds a bit too familiar, you’re not alone and you’re not stuck. The key to avoiding these common mistakes is making better decisions from the start. That begins with asking the right questions when choosing a payroll partner.
