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.

Having adequate access to adequate funding is fundamental for any startup. In the early stages of getting your enterprise off the ground, you need working capital to reach the all-important minimum viable product (MVP) stage, rent premises and hire staff. But where does this initial funding come from? Let’s look at the UK Government's Start Up Loan scheme and the funding options it offers.

Question: “Can cost-saving measures in the business truly be a key driver of profits?” Running a profitable business is one of your key goals as an owner. Without profits, there’s no capital to reinvest in the business, no funds to grow the company and no money for your own dividend payment at the end of the financial year. So, is cost-saving the answer in these challenging economic times? Answer: “Careful management of costs is a fundamental way to improve your profit margins and profitability as an enterprise” Cost-saving measures will have a direct and measurable impact on your profits. This is usually achieved via two main mechanisms. Firstly, reducing your variable costs (like raw materials or direct labour) increases your gross profit margin. This retains more revenue from each sale you make as a business. Secondly, lowering fixed overheads (such as rent or software licenses) directly reduces the total expenses on your profit and loss statement, leading to a higher net profit. This immediate bottom-line improvement makes you a more financially healthy prospect to investors and lenders – which, in turn, can often make it easier to access funding and grow the business.
