How to Set Up a Profit and Loss Statement

How to Set Up a Profit and Loss Statement

Let's talk about one of the most important tools in your business – the profit and loss statement (P&L). If you've ever wondered whether your business is truly making money, your P&L will give you the visibility you need to take action. Don't worry if numbers aren't your thing; we're going to break this down into bite-sized pieces that actually make sense.


What's a P&L?


Think of your P&L statement as your business's financial story. Just like any good story, it has a beginning (your revenue), a middle (your costs and expenses), and an end (your profit or loss). It's basically telling you whether you're making or losing money over a specific period. 


Revenue


First up is Revenue – that's all the money flowing into your business. Whether you're selling products, providing services, or both, this is where you capture every penny earned.


Cost of Goods Sold


Next comes the Cost of Goods Sold, or COGS as we like to call it. These are the direct costs of providing your products or services. In the construction industry, these are all your direct project costs – think materials like timber, concrete, and steel, subcontractor labour costs, equipment rental for specific jobs, and even those essential site-specific permits and insurances. For example, if you're working on a house extension, your COGS would include everything from the foundation materials to the roofing supplies, plus the direct labour costs of your team working on that specific project.


Gross Profit


When you subtract your COGS from your revenue, you get your Gross Profit. Think of this as your first checkpoint – it tells you how much money you're making before all those day-to-day running costs come into play.


Operating Expenses


Speaking of running costs, let's talk about Operating Expenses. These are all those necessary costs that keep your business ticking along – rent, utilities, marketing, insurance, etc. These are things which you need to pay for regardless of whether or not you make any sales.

When you subtract these from your gross profit, you finally reach your Net Profit or Loss – the real story of how your business is performing.


Making It Work for You


Now, you might be wondering how to actually put this all together. The good news is that you don't need to be a mathematical genius. Start by picking a time period you want to track – monthly is usually a good place to start. Then, gather all your financial records. Yes, all those receipts you've been stuffing in a drawer (we've all been there!) need to come out.


Modern technology is your friend here. There are brilliant accounting software options like Xero and QuickBooks that can do a lot of the heavy lifting for you. They can automatically pull in your bank transactions and help you categorise everything neatly. Trust me, your future self will thank you for embracing these tools!


If this all sounds a little overwhelming, here at Bluebells Bookkeeping we can produce these reports for you and ensure that they are fully understood.

Staying on Track


The key to a useful P&L is keeping it up to date, think of it as maintenance. Try to set aside some time each week to update your records. This way, you'll always have a clear picture of how your business is performing, and you won't face that dreaded end-of-year scramble.


When Things Get Tricky


Sometimes, despite our best efforts, things can get a bit complicated. Maybe you're not sure how to categorise certain expenses, or perhaps you're planning some big business changes and need to understand their financial impact. This is where having a bookkeeper in your corner can be invaluable. There's no shame in asking for help – in fact, it's often the smartest business decision you can make.



Your P&L statement doesn't have to be intimidating. Think of it as your business's financial health check – a way to keep your finger on the pulse of your success. When used regularly, it becomes an invaluable tool for making informed decisions about your business's future.


If you're feeling a bit overwhelmed with all this financial talk, don't worry – you're not alone. At Bluebells Bookkeeping, we love nothing more than helping business owners get to grips with their numbers.
