16 Different Types of Invoices For Your Business

1. Standard Invoice

A standard invoice, also known as a regular invoice, is the most common type of invoice used by businesses.

It includes essential details such as:

This type of invoice is versatile and can be used across various industries and billing cycles.

Example: A graphic designer completes a logo design for a client and sends a standard invoice for the service provided.

2. Proforma Invoice

Whether you bake cookies, manage social media accounts or change truck tires, your customers will likely want to know how much your service costs. That’s where the pro forma invoice comes in.

A proforma invoice is a preliminary bill of sale sent to buyers before the delivery of goods or services. It outlines the estimated costs and terms of the transaction but is not a demand for payment.

Proforma invoices are often used in international trade to declare the value of goods for customs purposes.

Example: A manufacturer sends a proforma invoice to a buyer detailing the cost of custom machinery before production begins.

3. Interim Invoice

Interim invoices are used for large projects that require partial invoice payments at different stages of completion.

This type of invoice helps maintain cash flow during long-term projects by allowing businesses to bill clients incrementally rather than waiting until the project is fully completed.

If you know when you’ll get paid, it’s easier to plan and cover your expenses.

Example: A construction company bills a client monthly for ongoing work on a building project.

4. Final Invoice

A final invoice is issued at the end of a project or after the delivery of goods or services.

It includes all the details of the work completed and the total amount due, minus any interim payments already made. This invoice signifies the conclusion of the business transaction.

Example: A marketing agency sends a final invoice after completing a six-month campaign for a client.

5. Recurring Invoice

Recurring invoices are used for ongoing services or subscriptions that require regular billing, such as monthly software subscriptions or utility services.

That type of invoice usually contains the same information about the product or service, and the same amount of money required, and it’s sent on a regular basis. Because of that, you can simplify recurring invoicing by using automated billing software.

8. Mixed Invoice

Mixed invoices combine both credit and debit charges on a single invoice. The total amount can be either positive or negative, depending on the net balance of the credits and debits.

This type of invoice is useful for businesses that need to adjust multiple charges in one document.

Example: A service provider adjusts a client’s bill by adding extra charges and providing a discount on another service.
