If you’re not making smart financial decisions as a business owner, you’re going to find that this impacts your bottom line sooner rather than later . Poor financial decisions show in different ways, from poor cash flow, fines for incorrect tax filings, money being tied up in investments or lost, or excessive debt repayments.

But there’s more than one way to make a bad financial decision, and this post is going to look at some decisions that will cost you more than you might realise.

Taking on Debt With No Clear Repayment Plan

Borrowing to grow your business is a legitimate strategy, that’s not the issue here. The problem is when you borrow without a clear repayment strategy.

Before you commit to borrowing for your business, you need to know how the repayments will impact your cash flow each month, and what it looks like compared to your actual revenue.

Because the loan amount and the interest are only part of the picture here. You need to know how it impacts your business in real terms, how the repayments will affect you when revenue is low, and how you’re going to manage this additional expense.

The main problem here is that many businesses lend against best-case scenarios and don’t account for periods when things aren’t at their best and don’t go to plan. So match the repayment plan to your actual cash flow, assess the lean months against the profitable pens nad assing a repayment strategy before you take on business debt, not after.

Missing Personal and Business Finances

You need a separate account for both your business and your personal income. This means separate bank accounts, separate credit cards, and separate spending pools used explicitly for the intended purpose.

Because once this line blurs, and you cross the line, tax reporting and balancing the books become instantly more complicated. And if you make one small error, you’ll be compounding this year after year.

So don’t cross that line initially, and if you have stopped now, separate everything and detangle your finances for improved cash flow and reporting moving forward.

Missing Depreciation and Tax Strategies on Property

This is a big one that many business owners can lose money on.

When your business owns commercial property, real estate depreciation is one of the most valuable tax positions available and also one of the most consistently under, used too.

The standard depreciation schedule is 39 years. A cost segregation engineering-based analysis that reclassifies components of the building into shorter depreciation schedules of 5, 7, or 15 years can accelerate those decisions. Recent changes mean that for qualifying assets placed in service in or after January 29th, 2025, components identified through a cost segregation study can now be fully expanded in the first year.

The result is lower tax liability rather than it being spread over 4 decades. And don’t worry, it’s a legally recognised IRS strategy typically used by larger corporations. However, a cost segregation study can help you identify tax savings you can make on commercial property as a small business owner, too.

Leaving Insurance Gaps

There is a gap between the type of insurance coverage your business needs and a standard policy. There will be different types of liability exposure for different businesses, es and these gaps,aps such as liability exposure, equipment, cyber risk, or business interruption, tend to stay hidden until they’re not, and your gap is exposed.

The resolution here is to review your coverage regularly and align it with a risk assessment or know vulnerabilities within your business and sector as a whole. This way, you cover the needs of the business instead of waiting until you need to make a claim to find out you don’t have the coverage you thought you did.

Waiting Too Long To Bring In The Right Advisors

The thing with bringing in advisors is that you get more value from them and their expertise when you bring them in before you need them. Using accountants, attorneys, or financial specialists before problems arise, not after, means you can avoid certain problems and make more informed decisions within your business.

An accountant can help you avoid tax issues down the line, and an attorney can steer you clear of legal mistakes like contract disputes or copyright breaches long before they land you in legal trouble. Because advice then narrows your options and will be more expensive than having the right advice beforehand, so you can make alternative decisions and align them with the best interests of your company.
