For an invoice to be rec­og­nized by the tax office as an official business document, you must comply with several formal re­quire­ments. Invoice templates can assist you in ensuring all necessary details are included.

What is an invoice template?

Invoice templates are sample invoices that contain all the required com­po­nents and can be used to map out new invoices. Instead of starting from square one and tediously as­sem­bling all of the elements on your own, such a template provides you with a complete example of an invoice with place­hold­er in­for­ma­tion that you just have to exchange for the real data.

Templates for invoices can basically be divided into text-based and tabular solutions. If only a few services need to be billed, then the former is almost always the more suitable choice. The more complex the billable services are, the more likely it is that a tabular invoice template will come in handy. This gives you the advantage of being able to arrange in­di­vid­ual prices and the overall price much more clearly. A template can also help you calculate certain values, such as the amount of sales tax if the ap­pro­pri­ate functions are installed.

What does a pro­fes­sion­al invoice template look like?

A pro­fes­sion­al invoice should be both clear and com­pre­hen­sive. On one hand, it must be visually appealing and easy to read so that customers can quickly find all relevant details. On the other hand, it must include all necessary in­for­ma­tion to ensure com­pli­ance with tax and record-keeping re­quire­ments. In­com­plete or in­ac­cu­rate invoices can cause issues during audits and may even impact tax de­duc­tions.

General invoice re­quire­ments in the United States

Unlike some other countries, the U.S. does not have a federally mandated standard for invoicing in general business trans­ac­tions. However, a well-struc­tured invoice should typically include the following elements:

  • Seller in­for­ma­tion: Business name, address, and contact details
  • Buyer in­for­ma­tion: Client’s name and address
  • Invoice number: A unique iden­ti­fi­er for tracking
  • Invoice date: The date the invoice is issued
  • Due date: The deadline for payment
  • De­scrip­tion of goods or services: A detailed breakdown of what is being billed
  • Quan­ti­ties and prices: Itemized list with unit prices and total amounts
  • Total amount due: The final sum, including any taxes or ad­di­tion­al charges

Special case: import invoices

For invoices related to imported goods, the U.S. Code of Federal Reg­u­la­tions (Title 19 §141.86) specifies ad­di­tion­al legal re­quire­ments. In these cases, the invoice must also include:

  • Port of entry and final des­ti­na­tion
  • Country of origin of the mer­chan­dise
  • All rebates, drawbacks, and bounties itemized sep­a­rate­ly
  • Any ad­di­tion­al costs (e.g., shipping, insurance)
  • Types of currency used (e.g., U.S. dollars, euros, etc.)
  • Any goods/services related to pro­duc­tion not included in the invoice price (e.g., molds, tools).

Be sure to check that the listed in­for­ma­tion is complete and accurate—es­pe­cial­ly if you are using a template solution for your invoices.

How to customize the invoice template step by step

After down­load­ing the free invoice template as a PDF, Excel, or Word file, you only need to customize it to meet your in­di­vid­ual re­quire­ments. Simply follow our in­struc­tions:

  1. First and foremost, enter your address in­for­ma­tion or the company address data in the top left corner. Directly un­der­neath, enter the customer’s address in­for­ma­tion.
  2. On the right side, you will find another place­hold­er for your own address in­for­ma­tion, along with ad­di­tion­al contact details such as a phone number or email address. If you do not offer this kind of support, simply remove the cor­re­spond­ing lines from the invoice template.
  3. Next is the invoice subject, which you can phrase freely. Instead of the simple “Invoice” that’s written in the template, you can, for example, also include the invoice number or any other agree­ments or con­di­tions.
  4. Below the subject, you will find three place­hold­ers for the invoice number, the customer number (optional), and the invoice date. Be sure to replace the example numbers here and don’t forget to enter the current date.
  5. The next line is des­ig­nat­ed for the header text, where you directly address the customer. Typically, you use this space to thank them for using your services or making a purchase and to provide a brief tran­si­tion in­di­cat­ing that the following section lists the invoiced costs.
  6. After ad­dress­ing the customer, the most important part of the invoice follows: the list of items (products or services). A table is available for this purpose, which you can expand or shorten by adding or removing rows as needed. The columns should include the item de­scrip­tion, quantity, unit price, and total price for each item.
  7. Below the table, you must specify the total amount due before sales tax as well as the total invoice amount including sales tax. Please note that the sales tax amount differs depending on the state.
  8. At the end of the invoice, there is another text area for ad­di­tion­al in­for­ma­tion, such as notifying the customer of the date the service was provided, or the goods were shipped. It is also common to specify the payment deadline for the amount due.
  9. The last section of the invoice template is the footer text. Here, you provide your contact details once again, along with the following bank account details, which the customer needs for the payment transfer:
  • Company name (to be used on checks)
  • Company address
  • Bank account in­for­ma­tion (if ap­plic­a­ble)
  1. Depending on the nature of your business, you may also need to include your tax iden­ti­fi­ca­tion number (TIN or EIN) if you are selling goods or services in­ter­na­tion­al­ly. VAT applies in many foreign ju­ris­dic­tions, but U.S. busi­ness­es typically do not charge VAT. Small busi­ness­es may qualify for ex­emp­tions, so it’s essential to check state-specific tax laws as well as the reg­u­la­tions of any country where you conduct business to ensure com­pli­ance.
  2. Now you can save and print your invoice template. It’s also possible to save the invoice as a PDF file so that you can send it as an email in the future.
