What is an invoice?

An invoice is a request for payment for goods and services, usually itemizing each one and offering explanations for every amount. It also includes fees, penalties, discounts, or other elements that can affect a total amount or subtotal. It usually informs a customer or recipient how and when to pay for said goods or services.


An invoice is distinct from a receipt, which documents and itemizes payment for goods or services.

When to use an invoice.

Vendors use invoices to inform their customers about payments and also to document transaction details. Invoices can help set and manage expectations for the time and manner of payments.


Digital invoices can help businesses and other vendors save time and money. Electronic invoicing, especially mobile invoicing, can make the entire payment process faster, smoother, and easier.

How to write an invoice.

When you create an invoice, align it with your existing accounting and tax filing needs. Familiarize yourself with regulations or laws in your jurisdiction or that of the recipients, and create your document accordingly. Also keep in mind how clients usually pay or prefer to pay, with payment options for debit or credit card, bank transfers, or using a third-party app like PayPal, depending on the norms and preferences of your industry.

Make payments easier for everyone with electronic signatures.


Invoices sometimes require the recipient’s signature, acknowledging that they have received the document and agree to pay. Electronic signatures can help speed up that process. E-signatures are legal and binding in every state and territory of the U.S. and in many other countries around the world.
