5 Common Accounting Mistakes Small Business Owners Make (And How to Avoid Them)
Starting your own business is exciting—but managing your books? Not so much. At Pillar Accounting & Business Services, we’ve seen how even the most passionate entrepreneurs can trip up on the numbers. The good news? Most accounting mistakes are preventable with the right systems and support.
Here are five of the most common missteps—and how to keep your business on solid financial ground.
1. Mixing Business and Personal Finances
Why it’s a problem: It makes tracking expenses a nightmare and can raise red flags with the IRS.
How to avoid it:
Open a separate business checking account and use a business credit card. Treat your business like the entity it is—distinct from your personal finances.
2. Falling Behind on Bookkeeping
Why it’s a problem: Delayed recordkeeping leads to costly errors, missed deductions, and cash flow confusion.
How to avoid it:
Schedule a regular bookkeeping day or outsource it to a trusted professional (hi, that’s us). Staying consistent saves time and stress down the line.
3. Not Saving for Taxes
Why it’s a problem: Many first-time business owners are surprised when tax season rolls around—and unprepared for the bill.
How to avoid it:
Set aside 25–30% of your income for taxes throughout the year. A tax savings account can be a real lifesaver when April hits.
4. DIY-ing Without Understanding
Why it’s a problem: Tools like QuickBooks can be powerful—but if used incorrectly, they can give you a false sense of security.
How to avoid it:
If you’re managing your books solo, invest in a bit of training. Better yet, work with someone who can review your records and ensure accuracy.
5. Skipping Financial Reviews
Why it’s a problem: You might be earning—but are you growing? Without regular check-ins, you won’t know what’s working (and what isn’t).
How to avoid it:
Make time to review your financial statements monthly. Look at trends, spot inefficiencies, and adjust accordingly. Better decisions start with better data.
