Taking care of your business accounting expenses can be challenging and carries a great deal of responsibility that can make or break your growth.

Outdated depictions of accounting, such as complex spreadsheets and towers of crumpled receipts, no longer reflect how modern businesses operate. Today, every business relies on accurate expense accounting and efficient financial practices to thrive.

In this blog, we’ll cover what accounting expenses are, how to categorise them, avoid common mistakes, and track them effectively.

What is expense accounting?

Expense accounting is the process of recording, categorising, and managing your business’s spending. It ensures your financial records are up-to-date and compliant with HMRC, while giving you a clear view of where your money is going. With well-managed expense accounting, you can forecast better, reduce tax liabilities, and make smarter financial decisions.

To understand how expense accounting works, you first need to know what accounting expenses are and what types your business might deal with.

Accounting expenses: What are they?

Accounting expenses, by definition, are money spent (or costs incurred) by a company in pursuing revenue.

An important distinction to make here is the definition of an ‘expense’ as opposed to a ‘cost’.

• Expense: Fixed expenditures, such as rent or utilities, that appear in your business taxes or balance sheet.
  
  
• Cost: Production and operations fees that estimate the amount a business pays for goods or services.

Example:

Let’s say you need to buy a car for your pizza delivery business. The purchase price is a cost. The petrol used for deliveries? That’s an expense.

Getting this distinction right is key to effective expense accounting and accurate profit reporting. After all,

                                              Revenue – Expenses = Total Net Profit

Now that we’ve highlighted the difference between costs and expenses, let’s run through some examples of the business expenses that are likely to crop up in your expense accounting process:

Types of accounting expenses

Direct expenses vs. Indirect expenses

An expense is considered direct or indirect based on its purpose and the stage at which it arises in your business operations.

• Direct expenses are directly related to the core operations of your company, typically linked to the purchase or production of goods and services.
  
  
• Indirect expenses are necessary to keep the business running but are not directly tied to revenue-generating activities.

Operating vs. Non-operating expenses

• Operating expenses refer to selling and general administrative costs, including anything related to delivering goods or services, such as staff salaries and paid advertising.
  
  
• Non-operating expenses, on the other hand, are not connected to operating revenue. For example, if your company has an interest-based bank loan, the repayment fee would be classed as a non-operating expense.

Fixed vs. Variable expenses

• A fixed expense is one that does not change over time, or changes only marginally. Examples include monthly rent or insurance for your workspace.
  
  
• Variable expenses, however, change from month to month. These are typically a company’s largest expenses and may include freelance staff payments or overtime salaries.

What is an expense account?

An expense account is where you record all the business expenses that keep your company running. It’s a key part of expense accounting, helping you track, organise, and manage your spending so you always know where your money is going.

Most businesses divide their expense account into sub-accounts, such as rent, utilities, salaries, travel, and software costs. These expense account categories make it easier to monitor where money is going and create more accurate budgets.

That’s why accurate expense tracking is essential. If sub-account balances are incorrect, it can distort your total expense balance and lead to errors in your financial reporting.

Types of company accounts

Expense accounts are just one piece of the puzzle when it comes to managing your business finances. Here are the other key types of accounts you’ll want to keep an eye on:

• Income accounts – Track how your business earns money from sales, services, or other revenue sources.
• Asset accounts – Show what your business owns, like cash, inventory, or equipment.
• Liability accounts – Reflect what your business owes, including loans and unpaid bills.
• Capital accounts – Reveal your business’s net worth at a specific point in time, after debts are accounted for.

Methods of recording business expenses

Now that you understand what an expense account is and how it fits into your overall accounting system, let’s look at the two main ways used in expense accounting to record business costs. These are: Accrual accounting and Cash accounting.

1. Accrual accounting

Accrual accounting records expenses when goods or services are received, even if the payment is made at a later date. This method provides a more accurate picture of your business’s financial position by matching expenses to the time they are incurred.

For example, if you receive materials in March but pay the invoice in April, you would still record the expense in March using the accrual method.

2. Cash accounting

Cash accounting only records expenses when the money has actually been paid. It is a straightforward method that reflects your actual cash flow, which is why it is commonly used by startups, sole traders and small businesses.

Using the same example, if you are following cash accounting, you would record the expense in April when the payment is made, not in March when the goods were received.

What are allowable expenses?

Allowable expenses are the essential costs that keep your business running. These costs can be deducted from your total income to work out your taxable profit, which means you do not pay tax on them.

However, it can sometimes be unclear what counts as an allowable expense and what does not. Claiming something that is not eligible can lead to complications, so it is important to be confident about your records.

Examples of allowable expenses include:

• Staff wages and salaries
• Business insurance
• Office rent and utility bills
• Equipment and supplies
• Software and subscriptions
• Advertising and marketing costs

If you are ever unsure, it is a good idea to check with an accountant to make sure you are claiming correctly and staying compliant with HMRC.

Tips for managing business expenses the right way

Once you understand the basics of expense accounting, it’s just as important to manage your costs effectively. Here are a few things to watch out for:

• Keep business and personal spending separate
• Record even the small day-to-day purchases
• Claim all the allowable deductions you are entitled to
• Keep your records organised throughout the year, not just at tax time
• Double-check that every expense is in the correct category

Avoiding these common mistakes helps keep your records accurate, simplifies tax returns, and gives you better control of your cash flow.
