Top 3 Small Business Accounting Mistakes
June 20th, 2022 | 5 min. read

Some small business owners want a more affordable accounting option. However, what you pay for is what you get – and cheap or "DIY" accounting can often result in record inaccuracies, a short-term focus, and fear of change. Don’t even get us started on missed opportunities!
Working with small businesses in Minneapolis and beyond for more than 50 years, we’ve seen our fair share of accounting mistakes by owners and operators. Most of these small business accounting mistakes are simple to correct, but even easier to avoid (once you’re aware of them).
Cut out mistakes before they happen! This article touches on the top three accounting mistakes made by small businesses (and a bonus mistake to avoid at the end).

1. Failing to Reconcile Bank Accounts
Reconciling bank accounts means matching up your accounting software to your bank statements. This is essential for small businesses to ensure that all transactions have been completely and accurately captured in the accounting record on an ongoing basis.
Failure to reconcile bank accounts is one of the most common risks that small businesses face. Most small businesses who handle this on their own are doing it once per quarter – or whenever they get the chance. We recommend reconciling your bank accounts monthly.
If you don’t reconcile your bank accounts each month, it puts the business at risk for the following:
- Misappropriation of cash
- Increased risk of basic accounting errors
- Inaccurate financial and tax reporting
- Loss of deposited funds from bank errors
- Various penalties and fees with NSF checks or overdrafts
2. Only Focusing on the Short Term
With the day-to-day hustle of running a small business, it’s easy to fixate on the short term. Accounting, however, is not just about keeping track of today’s numbers. You need accounting practices that forecast future potential and identify any financial risks ahead.
If you don’t know where to start with looking to the future, consider looking into complete tax planning and getting tax projections done for your business. Year-round tax strategy goes beyond what an annual tax accountant can provide for you since they’re only in your books once per year.
3. Not Letting Go
If you're handling your own accounting, it’s tough to admit that you need help, but there are situations when resisting professional help is a major mistake. You likely started your business with a great idea that had nothing to do with accounting. That’s where your focus should be.
While you won’t be able to tell when an accountant can help you most of the time (such as when you owe more in taxes than you should, accounting items are incorrectly coded, etc.), be aware that an accountant should help you with large financial decisions where there can be repercussions for doing them incorrectly, such as:
- Buying equipment
- Taking out a loan
- Considering offering a new product or service line
- Selling something when you have little knowledge of sales tax
Most likely, you're concerned that having an expert do the work will cost you an arm and a leg. However, record inaccuracies can result in penalties and interest down the line or make you miss out on reimbursable expenses. Not to mention, going through an audit will take up a lot of the time that you could have put toward making profits.
How can you tell if your bookkeeping is getting mixed up? Start by taking a look at your financial statements. Here are some common red flags.
Bonus Mistake: Hiring the Wrong Accountant
Whether it’s a family member or an inexperienced part-time accountant, the wrong hire can create financial problems that go beyond just making uninformed decisions. It can haunt your small business for many years to come.
