How to Invoice Someone
Do you need to issue a sales invoice but don’t know the best method? You’re in luck! This article will discuss different ways of issuing an invoice and what to include on an invoice.


First, we will look at the information required in a sales invoice. It will vary depending on the country you are billing in, so it is best to consult with your local accountant or tax authority. However, invoices generally include some standard items.
We will then look at the different ways to issue an invoice. You can use accounting software or create an invoice template in Excel or Word.
What is a Sales Invoice?
A sales invoice is a document that records a sale transaction. It includes information about the sale, the date, items sold, and the price of each item. It also provides information about the buyer and seller, such as their contact information.
The purpose of a sales invoice is to provide a record of the sale transaction so that both the buyer and seller can refer to it if needed. It also serves as a bill for the buyer to pay for their purchased items.
If you’re a small business that’s VAT registered, you’ll need a vat invoice that includes sales tax, your VAT number, and the total amount to pay.
How to Invoice Someone with Professional Looking Invoices
Creating professional invoices is essential for your business brand. It means using a logo, company brand if you have one and company colours. Having a handwritten invoice does not look good in a business, even if you are a sole trader.
What does a sales invoice include?
The information required on business invoices will vary depending on your billing country. Including as much information and precise payment details will help get paid faster.
However, some general items are:
Your Business address and Name
Including your company name and address on an invoice is essential for two reasons. First, it helps to identify the sender of the invoice. It can be helpful if there are any questions or disputes about the invoice. Second, it provides contact information for the buyer if they need to get in touch with you.
It is best practice to include your company name and address at the top of the invoice and any contact details, including phone number, email address and website.
If you’re a limited company with a different registered address, include it on the invoice. Also, have the company registration number.
The customer’s business name and address
When you invoice someone, you’ll want to include their business name, address and contact person. Including the full details will help ensure that the invoice is delivered to the right person and easily pay the bill.
The invoice date
The invoice date is the date on which the invoice is issued. It is essential as it is the date for the payment terms and also if there is a return or warranty period.
Unique Invoice Number
An invoice needs to have a unique invoice number to track the document easily. This number can be assigned by the accounting software you are using or create a numbering system in Excel.
Having a unique identification number allows easy tracking of the invoice, and the customer will quote it when paying.
The invoice number is a good reference to use if there is a query on an invoice.
Purchase Order Number or Reference
If the customer has provided a purchase order number or reference, ensure this is added to the invoice.
Details of the goods or services
When you issue a sales invoice, you’ll want to include a detailed description of the sold goods and services. It will help ensure that both the buyer and seller are clear on what was purchased.
Include the following information
- A full clear description of the goods or services sold
- Quantity of each item
- The unit price of each item
- Discount, if any
Supply Date
Provide the supply date the goods or services were provided.
Payment Terms
There are a few things you should keep in mind when it comes to payment terms.
You should always be clear about the payment term when you issue the invoice and any sale agreement. This will avoid any confusion or disputes later on.
Charge interest on late payments. Charging interest will help to ensure that you receive payment on time or early.
Try to get payment in full when the invoice is issued. This will reduce the time and energy you need to spend chasing payments.
Below is a list of different payment terms that a business might use:
- Immediate payment
- 7 Days
- 14 Days
- 30 Days
- Net Monthly – payment is due at the end of the following month of invoice. An example of this is an invoice issued in June that is due for payment on 31st July.
Some small businesses will ignore the payment date and include it in their payment run; that might only be a monthly process.
Always ensure that the payment date is clear on the document.
Payment Due date
Adding the payment due date clarifies to the customer when they should make payment.
Ways to Pay the Invoice
To receive payment, you might also want to offer a few different ways to pay the invoice and make them clear.
Some of the most common payment methods are:
- Cash – typically used if paid for in person
- Cheque – due to the processing time
- Credit card
- PayPal
- Bank transfer – A popular payment method, ensure to add the business bank account details
- Direct Debit
- Standing Order
- Integration in accounting software – the customer can create an account and pay through the account. It is an excellent way to get paid faster.
Total Amount
When you issue a sales invoice, it’s essential to make sure that the total amount is clear. This will help avoid any confusion or disputes about how much the customer needs to pay.
VAT Invoices
If you are a VAT registered business, you will need to issue a VAT invoice clearly showing the sales tax rate, VAT amount and registration number. This will help to ensure that the buyer is aware of how much tax they need to pay and enter in their records.
The VAT invoice is used to determine how much VAT must be paid to HMRC.
