What Is an Invoice?
An invoice is a request for payment for itemized goods and services that is sent from a seller to a buyer. Invoices are used by a person or company (offering goods or services) to tell a buyer that payment is now due.
A basic invoice should include the following details:
- Seller: person or company offering goods or services
- Buyer: person or company purchasing the goods or services
- Description: detail of each item sold or service provided
- Due Date: when payment is expected, either in 30 days or by a certain date
- Payment: whether the buyer should pay by check, money order, or other means
- Purchase Order Number: a unique identifier used to keep track of orders
As a reference, this type of document may be referred to as a:
- Bill of Sale
- Itemized Bill
- Purchase Invoice
What Is an Invoice Used For?
As a commercial document, an invoice is needed whenever a business transaction involves paying for goods or services. Invoices are used to track inventory, accounts receivables, and expenses. The seller can send one to the buyer once a transaction is completed or within 14 days of the transaction.
An invoice can be sent to the buyer immediately or within 14 days of the business transaction.
How Do Invoices Work?
Invoices work by providing those in a business relationship with a formal account of all goods and services rendered as well as a statement of the total sum owed. Once sent to the buyer, an invoice acts as an official record of the transaction.
Without a written invoice, the seller has no written proof that a business transaction occurred. After the seller provides goods or services, the buyer could simply not pay if an invoice isn’t sent. Practically speaking, invoices also serve as a professional reminder that payment is still due. Legally, they’re enforceable in court if the buyer continues to not pay or the seller provides bad goods or services.
|Seller’s Preventable Consequences||Buyer’s Preventable Consequences|
|Loss of Money||Loss of Money
|Loss of Time||Loss of Time
Once payment has been received and/or processed, the seller can issue the buyer a receipt.
A properly sent invoice will address the following basic questions:
- Who are the seller and buyer
- What item or service is being purchased, including a description
- Where the items should be delivered or service performed
- When the payment is due (i.e. 30 days from the invoice date or before a certain day)
- How the payment should be made (i.e. check or money order)
Who Needs an Invoice?
If you want to get paid for goods or services provided, you should send an invoice. Freelancers, businesses, and service providers of all shapes and sizes use invoice templates or specialized apps to collect payments from clients.
Here are just a few of the professionals who may need one:
|Attorneys/Lawyers||Advertisers||Computer & IT Service Providers|
|Photographers||Shipping and Package Providers||Landscapers|
|Technical Writers||Traders||Pet Sitters|
What’s the Difference Between a Purchase Order and an Invoice?
An invoice is a payment request sent to a client from a vendor after the order has been fulfilled. It details the goods or services involved and the amount of money that is owed. A purchase order (PO) records a business transaction between two parties, typically large orders between a buyer and a seller.
Purchase order vs invoice – key differences:
|Request for payment sent from a vendor to a client||Indicates the intent for purchase to take place|
|Created by the vendor after an order is fulfilled||Issued by the buyer when large purchases are made|
|Details the confirmation of sale or service||Defines the terms of a purchase|
|Acts as a payment reminder and prevents duplicate or overpayment||Helps prevent overstocking of inventory|
How to Fill Out an Invoice?
Filling out an invoice is a fairly straightforward process, made even easier by using a template or our step-by-step builder which includes all the important details:
Step 1 – Company Name and Contract Details
Start off by including your business name so your clients can easily identify you. Follow up with the contact details of your business, including address, phone number, and email address.
Step 2 – Client Contact Details
Next, you’ll want to include the client’s contact details. Ensure you’re billing the correct client, whether an individual or another business. Include the client’s name, address, phone number, and email address.
Step 3 – Invoice Number
Use a unique invoice number so you can easily refer back to it when you’re doing recordkeeping for your business or if you need to refer back to a specific invoice. If it’s your first invoice you can simply label it as invoice 1 and then increase the invoice number as you create more.
Step 4 – List the Goods or Services
Provide an itemized list of the goods or services provided. If you’re selling goods you need to list each specific item with the amount and the price. If it’s a service, you should document the number of hours worked and the hourly rate charged (alter as necessary if charging a day or project rate). Don’t forget to include the total cost.
Step 5 – Billing Information
Include details regarding your accepted payment options, such as cash, credit, or debit card, and payment terms. You could include a payment link if you have one available – if not, don’t forget to include your account or bank information. If required, you can include an invoice due date at the top or bottom of the page to try and get paid faster.

What is an invoice number?
