As a small business owner, you probably have to create, send, and pay hundreds of invoices every month.

Now, depending on your industry, clients, and products or services, these invoices will differ from one another.

If you’re shipping products internationally, for example, a regular sales invoice won’t do the job. You will need to learn how to issue a commercial invoice, which includes extra details such as shipping costs and transport fees.

Don’t worry, though!

By the end of this guide, you will know everything about the different types of invoices, along with the ones that best fit your small business accounting.

9 Main Types of Invoices [with Examples]

To better understand the different types of invoices you can use, here are the nine main types of invoices small business owners deal with during their day-to-day business life:

1.  Pro-forma Invoice

Invoices are typically issued after the delivery of products and services. However, there are situations where buyers want to know what to expect from a purchase before doing it.

That’s when the proforma invoice comes to play.

A proforma invoice is a preparatory bill sent before work is finished. It details the payment just like the standard invoice would, but it’s not the official demand for cash. It only serves as an estimate of a sale, so the client can get an idea of how much the products and services will total.

And because it’s just an estimate and may be subject to change, a proforma invoice is not recorded as accounts receivable in the company books.

Usually, though, it still represents a more or less accurate total the customer has to pay in the end.

Here’s an example of what a proforma invoice looks like:

2.  Interim Invoice

The larger a project is, the more you have to spend on supplies, labor, and other operating expenses. To help with cash flow when dealing with these big and time-consuming projects, businesses use interim invoices.

An interim invoice, also known as a progress invoice, divides the total amount of a project into multiple smaller payments.

For example, let’s assume you take on a project that will last around 8 months. To cover some of the costs you could invoice your client 8 times in total, on a specific date, for every month of work.

This way, you also reduce the risk of not getting paid back and having to throw months of work down the drain.

3.  Final Invoice (Standard Invoice)

Just as the name suggests, the final invoice is the invoice you send after a project is done. This is what’s also known as a standard invoice.

In simple terms, it lets the customer know work is finished and includes the total amount owed, due date, payment methods, and an itemized list of all services.

Here’s an example of a final invoice:

4.  Recurring Invoice

Are you a subscription-based business? Or maybe you offer specific services for a monthly fee?

If the answer is yes to any of those questions, recurring invoices are the best billing option for your business.

Recurring invoices charge clients the same amount regularly, for repeated services. With cloud-based accounting software, you can set up recurring invoices so they get sent automatically at a fixed interval of time (e.g: once a month).

A recurring invoice looks the same as a standard invoice. The only difference is that it’s repeated every month.

5.  Commercial Invoice

A commercial invoice is issued by a business to request payment for products sold internationally. It includes extra details needed for shipment across the border such as:

  • Country of origin
  • Country of destination
  • Shipper and consignee
  • Weight and volume of product
  • Packaging format
  • Shipment terms
  • Authorized signature

Invoicing software like Deskera offers multi-currency support, which automatically calculates exchange rates to help you work seamlessly with international clients, and not worry about exchange rates or losses.

6.  Timesheet Invoice

Businesses or employees who charge by the hour use timesheet invoices to ask for payment.

Some of the most common jobs that use hourly billing include freelance programmers or designers, attorneys, counselors, psychologists, accountants, and business consultants.

As far as formatting goes, a timesheet invoice will usually have these distinctive elements:

  • Hourly rate
  • Total hours worked
  • Days and date of the days worked
  • Administrative fees

7.  Past Due Invoice

No one appreciates late payments, but there will be times your clients miss the payment date.

In those cases, the immediate answer is to issue a past due invoice.

A past due invoice serves as a reminder to the client to pay up an invoice that has passed the due date. It includes all of the prior invoice information, along with any appropriate late fees or interest charges.

8.  Credit Invoice

A credit invoice, also known as a credit memo, is an amendment to a previously issued invoice. It is used to recognize that your business owes the buyer money.

This is necessary for situations when:

  • Your business doesn’t follow through with delivering goods and services issued on an invoice
  • Products sent are damaged
  • The wrong products get delivered
  • There is a pricing error
  • The client wants to return the product

For any of the above reasons, a credit memo gets made with a negative total number, to reverse the previous incorrect invoice.

So, if you owe a client a $100 refund, the total of the credit invoice would be - $100.

9.  Debit Invoice

On the other hand, the debit invoice (or debit memo) is used to increase the charge against a client. There could be scenarios where you underbill them which you can correct by issuing a debit invoice.

For instance, if you end up spending more hours on a project than recorded on an invoice, you can send a debit invoice for these extra hours.

Both of these two types of invoices are used to make adjustments for accounting and bookkeeping purposes.

10.  E-invoice

An e-invoice refers to all invoices that get issued and delivered electronically, no matter the specific type or purpose of the invoice. This digitized method of invoicing is growing more and more popular by the day since it’s a faster and easier alternative to standard paper invoices.

An e-invoice allows you to get paid faster.

No need to print and mail the invoice. All you have to do is save it as a PDF, and send it via email.

Alternatively, you could also use invoice management software to send e-invoices with a single click directly from the software (or via sharing link).

The Essential Elements Every Invoice Should Include

While there are many distinctions between these invoices, there are some standard elements consistently displayed in every type.

The essential details every invoice should include are:

  • A header with the word “Invoice”
  • A unique invoice number
  • The billing date and due date of payment
  • Business and client contact information (name, email, phone number, and billing address)
  • A list and description of products sold or services rendered
  • Cost per unit, and the total amount owed
  • Other expenses such as taxes or fees
  • A clear description of the payment terms
