5 common accounting mistakes (and how to avoid them)

Anna Stubbs • May 29, 2024

Starting a business can be a challenging experience, especially when it comes to managing your numbers and staying on top of your financial management.



Unless you’ve got some experience in finance, the bookkeeping and accounting requirements can be quite daunting. And even with today’s helpful cloud accounting platforms and fintech apps, there’s always the possibility of making a simple accounting mistake.


So, what are the most common accounting mistakes made by business owners? And what can you do to avoid these pitfalls and keep your finances looking healthy and shipshape?

The top five accounting mistakes to avoid


‘Doing the books’ is unlikely to be your favourite part of running a small business. But the better your accounting know-how and skills, the more oversight you have over the financial path (and future success) of your company. It really is that simple.


But there are plenty of traps that a newbie owner can fall into – and even a few hurdles that the more experienced business owner may trip over from time to time.


Let’s take a look at the five most common accounting mistakes:


1. Mixing your personal and business finances – when you don’t separate your personal and business transactions, this blurs the lines and makes it difficult to track your income and expenses accurately. It can also lead to personal spending being counted as business deductions, causing tax issues later on.


Solution: Open separate business and personal bank accounts and keep them entirely separate and distinct.


2. Skipping the record-keeping process – if you fail to keep receipts, log your invoices and keep proper records this can be a major problem further down the road. Detailed records are crucial for tax filing, budgeting and identifying spending trends.


Solution: keep digital copies of all receipts and be sure to keep your bookkeeping up to date and well-managed.


3. Miscategorising your expenses – throwing all your expenses under ‘miscellaneous’ makes it far harder to analyse your spending and cashflow. With every item of expenditure logged under a specific code from your Chart of Accounts, you can quickly run reports, review your spending and look at ways to improve budgets and cashflow.


Solution: Categorise your expenses properly (rent, marketing, supplies etc.) to understand where your money goes.


4. Winging it when filing your taxes – Taxation is complicated and it’s easy to make costly mistakes if you’re not prepared and organised. Don't wait until tax season to sort everything out and make sure you’re aware of all your business tax liabilities.


Solution: Set aside funds for taxes throughout the year, and consider consulting an accountant or tax adviser to ensure you're filing correctly and taking advantage of all potential government deductions and tax incentives.


5. Failing to get proper accounting advice – if managing your finances becomes overwhelming, don't be a hero. Cloud accounting software can automate some of the key tasks, and a bookkeeper can handle day-to-day record-keeping.


Solution: think about outsourcing and partnering with an experienced accounting firm to get real peace of mind and improved financial management.

In 1961, President John F Kennedy famously announced his goal of landing a man on the moon and returning him safely to Earth before the decade was out. As we know, in July 1969, Neil Armstrong and Buzz Aldrin became the first people to walk on the moon, and were brought back to Earth safely, achieving JFK’s goal.  At a time when most people hadn’t even been on an aeroplane, landing on the moon would’ve felt unachievable and overwhelming. However, such a massive goal united people with a purpose; the story goes that even a cleaner mopping the floor at the space station said his job was to help put a man on the moon. So, how did they make the goal achievable? They broke it down into milestones, with each one taking them closer and closer to achieving their ultimate goal. The first milestone was to achieve lift off. So, they set about resolving this challenge. The next milestone was to reach orbit, so they had a team working on this milestone. Then, they had to reach the moon’s atmosphere, land safely on the moon, take off from the moon, enter Earth’s atmosphere and land safely back down to Earth. You can see how breaking the goal down into milestones gave everyone a more achievable objective to focus on which was less overwhelming. Those milestones were then broken down into the actions which needed to be completed. Each action was essentially a small step towards reaching the ultimate goal.

Are you undercharging for your services? It can be hard to tell, particularly if you’re in a niche industry or you’re a contractor. Costs have been rising, so it may be time to rethink your own pricing.

For your business to make money, you need to generate revenue. You produce revenue through your usual business activity, by making sales, getting your invoices paid, or taking cash from paying customers. So, the better you are at selling your products/services and bringing money into the business, the higher your revenue levels will be. But what actually drives these revenue levels? And how do you get in control of these drivers?
