What Is a Proforma Invoice?

A proforma invoice is a preliminary sales document issued to the customer before the completion of the work. In simple words, a proforma invoice is:

  • A commitment of goods or services that are yet to be delivered;
  • Providing you with the lists of the work to be completed;
  • Allowing you to input the quantity and the price you're charging for the products or services.

Proforma invoice is not being used for any accounting purpose. It means that you cannot demand or request any payment using a proforma invoice.

A Quick and Easy Guide to Proforma Invoice

Key Points

  • 01Proforma invoices are preliminary documents sent before work completion or delivery
  • 02They serve as price quotes or estimates but are not legally binding
  • 03Cannot be used for accounting purposes or payment requests
  • 04Help customers prepare budgets and obtain approval before final invoices
  • 05Speed up payment by giving customers advance notice of costs

Why is Proforma Invoice Created?

A proforma invoice does not carry an invoice number. We can say that it's one type of uncompleted invoice, and so is not legally binding. Therefore, it doesn't have much importance, like a proper sales invoice created for the sales process. Every invoice that is recorded or serves an accounting purpose should carry an invoice number. When you invoice a proforma bill document, it can be likened to purchase orders, a quote, or an estimate of goods and services the seller has committed for the business process.

A proforma invoice is created before the job is completed, just a quote has been sent, or before the goods get delivered. With the quotes, companies can make sure that the client is well-informed about the estimated cost. So, that they can be prepared for the estimated cost for the particular project.

A proforma invoice is sent to the client to affirm that they and the seller are dealing with the same figures and agreement. The proforma invoice includes the price and quantity of goods and services and gives the customer a direction of where sales are going or where the job has progressed to.

Best Practice

Use invoicing software like InvoiceOwl to ensure your proforma invoices are well-formatted and labeled correctly. Simply fill in the details, save, and send or print.

What is the Purpose of a Proforma Invoice?

The proforma invoice template from any invoicing software serves as a record to follow up on the goods and services. When the template is sent to the customer, they have to agree on the price or the value included following the purchase approval process. The next step that the small business owners need to perform is to send the customers with the goods or offer your services in the ways as agreed.

Aside from this purpose, here are other valid usages of the proforma template of invoice:

Common Uses for Proforma Invoices

  • Gives customers an overall idea of the value of expected goods for stress-free delivery and customs purposes
  • Provides cost estimates when all details of a commercial invoice are incomplete
  • Serves as a record for customers to obtain purchase approval internally
  • Required for international trade transactions or customs documentation

Difference Between Proforma Invoice and Invoice

Can Payment be Requested Using a Proforma Invoice?

The accounts payable section of a corporation the vendor is selling to may send an upfront payment on receiving an invoice proforma. After payment in advance, the seller knows how much to expect when he sends the actual invoice templates. When the goods and services have been completely delivered, the actual invoice is referenced to avoid double payment by the firm.

Important to Note

While proforma invoices aren't legally binding payment requests, some businesses use them to arrange advance payments. The actual invoice must still be sent after delivery to serve as the official accounting record.

Does a Proforma Invoice Help You Get Paid Quicker?

When you sell any product or service to the customer, they need to pay the bill within a specific time frame. In some countries, the default due date is 28 days after the original invoice is issued or a customer receives their products or services. The proforma invoice makes it easier for you to set the terms and get paid quickly.

The invoice due date is usually mentioned in the final invoice, but the proforma invoices can speed up the payment process by letting your customers know how much they owe. Proforma invoices give your customers time to make their minds and necessary arrangements for the payment.

In some companies, they have to take the permission of the managers and higher authorities, if they have received a proforma invoice prior to the actual invoice, they can take the payment permissions in advance. Such steps help businesses in getting paid through faster-invoicing processes.
