Hey there, fellow tradespeople! We get it, invoicing might not be the most exciting part of your job, but it's crucial to keep the wheels of your business turning. So, we're here to break it down for you in a fun and friendly way – think of it as a chat over a cuppa. Ready to learn all about invoices? Let's dive in!

What Should a Basic Invoice Look Like?

Imagine your invoice as a handy map to get you paid, and like any good map, it needs clear markings. A basic invoice should include:

Header: Your invoice begins with the header, where you'll want to feature:

  • Your Business Information: Your business name (or your name if you're a sole trader), address, and contact information.
  • Client Details: Ensure you include your client's name, their address, and their contact information. This part helps you and your client to know who's who.

Description of Services or Products

This is where you describe the services or products you've provided. It's not the place for cryptic clues! Be specific and itemise if you need to.


Quantity and Price

If you've provided multiple services or items, you'll need to show the quantity and the price for each. This gives your client a clear view of what they're paying for.



Calculate what's owed for each line item by multiplying the quantity by the price. These subtotals help break down the overall cost.


Total Amount Due

This is where the magic happens. Sum up all the subtotals, and you'll get the grand total that your client needs to pay.


Payment Terms

Clearly specify your payment terms. Let your client know when the payment is due, and if you're feeling generous, you can mention any discounts for early birds and penalties for late payments.


Payment Instructions

Help your client pay you by providing clear payment instructions. Whether it's bank details for bank transfers, information for cheques, or other accepted payment methods, make it straightforward.


VAT Info (if applicable)

If you're VAT-registered, you'll need to include your VAT number and any applicable VAT amounts. This is a must to keep things legal.


Legal Bits

Last but not least, make sure your invoice complies with the law. Cross those 't's and dot those 'i's to avoid any legal complications.


Feeling overwhelmed? Don't fret! In this digital age, you have tools at your disposal that make invoicing a breeze. You can use professional invoice templates or accounting software to ensure your invoices are both accurate and professional. Need a reference point? Check out a sample invoice here for inspiration.
