Summary

  • An invoice is an itemized request for payment
  • It serves as a legal record of a sale and payment obligation
  • It also helps businesses track revenue

If you own a business or have made a major purchase from one, you might have a basic familiarity with invoices. But what is an invoice, and why does your business need one? Let’s look a little closer.

Understanding Invoices and Their Purpose

You might wonder: What is an invoice for? An invoice is an itemized document that serves as a sales record and formally requests payment. Businesses typically send invoices to customers when payment is expected at a later date.

Creating invoices also establishes a clear sales record for the business, making taxes and revenue tracking easier.

Key Elements Every Invoice Should Include

When deciding what to include on an invoice, start with the basics. Usually, an invoice should at least include the following:

  • Contact information
  • Individual invoice number
  • Date of the invoice
  • Due date
  • Date of service
  • Detailed individual line items
  • Amount of money due for each line item
  • Payment terms
  • Accepted payment methods

Detailed invoices reduce confusion and show customers what they’re really being billed for.

Even when you promptly send invoices, though, you may still struggle with collecting payments on time. That’s why invoice payment terms are so important. Payment terms let the client know exactly how long they have to deliver payment. Here are some examples of common terms:

  • Net 30/60/90: Payment is due within the stated number of days from the invoice date.
  • End of Month (EOM): Payment is due at the end of the month in which the invoice was sent.
  • Due Upon Receipt: Payment is expected as soon as the client receives the invoice.

Your invoice should also specify any late payment penalties. To discourage late payments and avoid cash flow problems, some businesses choose to offer early payment discounts.

Common Types of Invoices Explained

You might wonder: What is an invoice for, exactly? That depends on the type of invoice. Invoices are used across virtually every industry. Consider these common types:

Invoice vs. Bill vs. Receipt

Invoices, bills and receipts aren’t exactly the same, and knowing how an invoice differs from a receipt can help keep your records straight:

  • Invoices are sent to request payment, usually at some point in the future.
  • Bills are sent to request immediate payment.
  • Receipts are issued to confirm payment.

Although this isn’t always the case, invoices are common in business-to-business transactions. Bills are often sent to individual customers.

How Invoices Are Used in Business Operations

Invoices aren’t just bills. They’re used to request payment, create a sales record and track your revenue. A custom invoice makes it easier to keep track of your money, and the right one can help you protect yourself. Thankfully, it’s easy to find professionally reviewed legal forms when you turn to ConsumerShield.
