Avoiding Common Summer Accounting Mistakes

Summer feels like the season to let things slide a little—but if that includes your accounting, you're setting yourself up for a rude awakening come fall. Whether it’s payroll errors caused by time-off confusion, cash flow assumptions that miss the seasonal swing, or simply falling behind on record-keeping during vacation season, the summer slump can lead to more than just a sunburn.

Straight Talk CPAs works with businesses across all industries to catch and correct summer accounting issues before they spiral. From keeping cash flow steady to tightening up payroll procedures and staying on top of documentation, let’s walk through what can go wrong—and how to keep your finances from melting down.

The Hot Weather Trap: Why Summer Sparks Mistakes

Here’s what’s happening behind the scenes:

• Payroll processors go on vacation. So do employees. And somewhere in between, someone forgets to update hours or process a bonus.
  
• Sales slow down—but expenses don’t. Many businesses face a seasonal dip in revenue during the summer, but bills keep coming.
  
• Owners unplug. Taking time off is healthy, but it also means decisions might get delayed or financial blind spots appear.
  
  

Add in a touch of overconfidence—“We always bounce back in Q4”—and it’s the perfect storm for accounting mishaps. Let’s break down the big three.

Mistake #1: Making Faulty Cash Flow Assumptions

Summer is notorious for messing with cash flow. Some industries (like HVAC or tourism) see a spike, while others (like B2B services or education vendors) dip hard. The worst move? Assuming the trend will fix itself.



What to watch for:

• Delayed receivables: Clients take vacations, too, and payment processing often slows.
  
• Over-ordering inventory: A spike in early summer doesn’t mean demand will last.
  
• Neglecting forecasts: Mid-year is the perfect time to refresh projections—not ignore them.
  
  

What to do instead:

• Use a rolling 13-week cash flow model to stay on top of dips and spikes.
  
• Set up automated invoice reminders to keep receivables on track while your team’s out.
• Review seasonal patterns from prior years—your P&L is trying to tell you something.
  

Mistake #2: Payroll Errors in Vacation Season

Summer PTO can turn payroll into a jigsaw puzzle—especially with manual processes or unclear policies. If someone misses a timecard deadline, doesn’t log PTO properly, or if your temp workers’ hours aren’t calculated correctly, the errors can snowball fast.

What we see often:

• Overtime miscalculations when teams are stretched thin
  
• Temporary employees misclassified or not entered into payroll at all
  
• Bonuses or summer stipends forgotten or doubled up
  
  

Smart moves to prevent it:

• Integrate your time-tracking software directly with payroll
  
• Double-check employee classifications, especially for seasonal or temp hires
• Set calendar reminders for upcoming pay runs (and make sure backup staff are trained)
  
  

Mistake #3: Falling Behind on Record-Keeping

It’s tempting to “deal with it later” when everyone’s in and out on vacation. But by the time August ends, you’re left staring at a pile of receipts, bank statements, and missing invoices—and your books are a mess.



Red flags:

• Credit card charges not categorized
  
• Vendor bills sitting unpaid or paid late
  
• Reconciling accounts only once at summer’s end
  
  

Better approach:

• Schedule weekly check-ins (even 30 minutes!) to keep your books current
  
• Use cloud-based accounting tools that let your bookkeeper handle things while you relax
  
• Set up rules for recurring expenses so they’re automatically categorized
