Business Planning

What financial documents should every business owner understand?

Running a business requires more than just a good idea of how to provide your products or services. You also need a good grasp on the financial side of things, which means understanding all the essential financial documents that help you to keep track of your business’ performance, stay compliant and plan for the future.

A lot of business owners either ignore financial documents or depend on accountants, without really knowing what the numbers mean. But, if you want to succeed as a business owner and grow your business, you need to know the difference between a balance sheet, accounts payable and a P&L statement.

Do You Know The Difference Between These Documents?

Profit and Loss (P&L) Statement

A P&L statement shows your business’ financial performance over a set time. It details the business’ income, the cost of goods sold (COGS), gross profit, running costs, and net profit or loss. Your P&L statement tells you if your business is really making money, enabling you to keep an eye on performance over time, determine your operating costs, decide how much to charge and how much to invest. It also makes it easier to see which parts of your business make the most money.

Balance Sheet

Your balance sheet provides an insight into how much money your business has at a specific moment. It includes your assets, liabilities and your equity. With a balance sheet, you can figure out how stable your finances are, how much debt your business has and whether you’re able to meet your upcoming financial commitments.

Cash Flow Statement

A cash flow statement shows how much money comes in and goes out of your business. It’s divided into various activities, covering operating, investing and money-making. Cash flow is what keeps your business going from day to day, helping you to plan for future costs, handle seasonal fluctuations and avoid running out of cash. If you don’t handle your cash flow well, you run the risk of going out of business, even if you are technically making money.

VAT Returns

If your business is registered for VAT, you have to send VAT returns to HMRC. This includes both output VAT and input VAT. By understanding how VAT returns work, you can make sure your reporting is correct, your pricing is right and you’re managing cash flow well. It also helps you to avoid making mistakes that could cost you further down the line.

Corporation Tax Return

Based on taxable profits, this financial document details how much corporation tax your business owes, factoring in allowable expenses, non-deductible costs and tax relief. It allows you to plan for tax liabilities, take advantage of available reliefs and avoid a surprise at the end of the year.

Accounts Payable and Accounts Receivable

Accounts receivable and accounts payable – which refers to the money that people owe your business, and the money that your business owes – help you to manage your working capital, monitor payment cycles and maintain a healthy cash flow.

Annual Accounts

Companies House requires limited companies to make and file annual accounts, including a balance sheet and P&L statement. Annual accounts are key for legal compliance, transparency and building stakeholder trust. They also give you a full picture of how your finances did over the year, which is important to know as a business owner, especially if you’re hoping to grow.

Payroll Reports

Payroll reports show how much each of your employees makes, alongside how much is deducted from their salary. This includes gross wages, PAYE, NICs and pension contributions. Understanding payroll reports means you can make sure staff get paid the right amount, you’re reporting accurately to HMRC and you’re on top of your legal obligations.

Don’t Understand Financial Documents?

Not understanding your business’ financial documents doesn’t just make things confusing when it comes to working out how much you can spend and how much money you’ve made, it also makes you vulnerable.

  • You Could Face Compliance Issues – You could get in trouble with HMRC, pay fines or penalties, or face legal complications. These are costly, stressful issues that can be avoided by better understanding key financial documents.
  • You Might Make Poor Strategic Decisions – You might trust your gut instead of the facts, which could lead to you making mistakes in pricing, spending too much or investing money in the wrong places.
  • There’s a Chance of Cash Flow Problems – If you can’t see how much cash is coming in and going out of your business, you might not be able to pay your employees, suppliers or tax, even if your business seems to be making money. There’s always a risk of you accidentally overspending if you’re not completely sure on what you have to spend.
  • You Might End Up Relying Too Much on Others – Accountants are important, but if you don’t understand your business’ numbers and financial documents, your control is limited.
  • You Increase Your Risk of Failure – A lot of businesses fail, not because there isn’t enough demand for their offerings, but because they don’t handle their money well. It’s much harder to see warning signs early if you don’t understand the information in front of you.
  • You Could Miss Out On Growth – If you don’t have accurate financial information to refer to, you might miss out on chances to grow, invest or make operations smoother. This could hold your business growth back.
