What are the parts of an Invoice? Invoice checklist

Chances are you’re going to stumble across an invoice at some point in your professional career. When enterprises conduct trade among one another, invoices are the standard way to pay for an order. Understanding what you’re looking at when handling invoices will help you pinpoint ways to streamline your payments process, creating a more efficient and cost-effective business. In this article, we’ll break down the parts of an invoice, so you can confidently process payments from your customers. 

What is the purpose of an invoice?

An invoice is a way for companies to track payments for orders and monitor their cash flow. Invoices serve as a record of sale and set payment terms that organizations both agree to adhere to to ensure payment for orders and services. They grant a way for both parties to track:

  • The sell date of the good or service
  • How much the organization is being charged for the good or service
  • Outstanding balances the organization owe

The other purpose of an invoice is to protect your enterprise in the event of an audit. Invoices provide a receipt of transactions. When properly filled out, invoices can provide a detailed description of your cash flow and where it originates. 

When it comes to documentation, the invoice amount is entered as Accounts Payable on the buyer’s end. On the seller side, the invoice amount is entered in the Accounts Receivable column. 

What are the parts of an invoice? 

There are five parts to an invoice that are all crucial for creating an accurate invoice. Put together; these things provide a detailed overview of the entire transaction, including the order, payment terms, and total amount due. These five sections include: 

1. The invoice number 

For every invoice you issue, you should assign an invoice number. This creates a trail of information for you and your customer’s tax and accounting records. Normally, invoices are not due right after they are issued. There are various payment terms you can set up to provide flexibility to your customers, which we’ll dive deeper into in a moment. 

Pro Tip: Use a sequential order system when assigning invoice numbers to keep things organized. Make sure every new invoice you issue is one number higher than the last. 

2. The date

The date on the invoice refers to the day the seller officially recognizes it as the transaction date. This date is the same as the date the seller bills the customer. A crucial piece of information, the invoice date, helps to define the payment due date and credit duration clearly. 

Did you know? Most commonly, the due date is listed as 30 days after the invoice date. But, based on your specific transactions and needs, this time can be changed.

3. Contact information for the business

This information is very important for ensuring organizations can contact one another in case of questions or troubles. Commonly, both the buyer’s and seller’s information will be included in the contact information area. Typically, this information includes:

  • The business name
  • The business address
  • A phone number for contacting the business
  • An email address for communicating with the business

4. A description of the goods or services

For every product or service you provide a customer, you need to add it as a line item on invoices. This helps create a detailed explanation of the products and services for which the customer is being charged. On each line item, include the price and quantity associated with it. At the bottom of your invoice, add a subtotal of all the above line items, list any tax charges the customer will be charged, followed by the full amount owed. 

5. Payment terms

For accurate records for both parties, the terms of payment need to be clearly stated. These are the terms and conditions the buyer agreed to pay within, specifying the time period the customer has to complete payment. Often, it is a strong strategic move to create payment terms that strongly encourage early payments to increase the likelihood of being paid. Additionally, payment terms dictate how late payments will be handled. 

Common invoice payment terms include:

  • Payment in advance (PIA) — means you ask customers to pay the full amount before the good or service is delivered.
  • Cash in advance (CIA) — like PIA, cash in advance means you expect a full payment, in cash, before the good or service is delivered.
  • Upon receipt — means once the customer is billed and receives the invoice, they are expected to pay in full immediately.
  • Net XX — “net” refers to the number of days you expect to receive full payment after billing the customer. Often, 30 days is used as a due date, which means that after 30 days from receiving the invoice or Net 30,  the seller expects the entire payment. 
  • End of month (EOM) — this means that the seller expects full payment by the end of the month listed on the invoice date
