Proforma Invoice: What It Is, When to Use It, and Free Template

A proforma invoice looks like an invoice but isn't one — not legally, anyway. Understanding the difference can save you from accounting mistakes and client confusion.

What Is a Proforma Invoice?

A proforma invoice is a preliminary document sent to a buyer before goods are delivered or services are performed. It outlines:

  • What will be provided
  • The estimated cost
  • Payment terms
  • Delivery timeline

Think of it as a detailed quote in invoice format. It says "this is what it will cost" rather than "you owe this amount."

Proforma Invoice vs. Regular Invoice

| | Proforma Invoice | Regular Invoice | |---|-----------------|-----------------| | Purpose | Estimate / proposal | Payment request | | Legally binding | No | Yes | | When sent | Before work/delivery | After work/delivery | | Recorded as revenue | No | Yes | | Can be modified | Yes, freely | Only via credit note | | Used for tax | No | Yes |

When to Use a Proforma Invoice

1. International Trade

Proforma invoices are standard in import/export. Customs authorities often require them to:

  • Assess duties and taxes
  • Process import permits
  • Verify the declared value of goods

2. Client Approval Before Starting Work

Send a proforma invoice when:

  • A client requests a formal cost breakdown before committing
  • You need written approval of scope and pricing
  • The project is large enough to justify a formal proposal

3. Securing a Deposit

Use a proforma invoice to request an upfront payment before starting work. Once the deposit is received, convert it to a regular invoice.

4. Internal Budget Approval

Large companies often need a proforma invoice to get internal budget approval before issuing a purchase order.

What to Include on a Proforma Invoice

A proforma invoice contains the same elements as a regular invoice, plus:

  1. "PROFORMA INVOICE" header — Clearly labeled so it's not confused with a real invoice
  2. Validity period — "This estimate is valid for 30 days"
  3. All standard fields — Sender, client, line items, totals
  4. Terms and conditions — Scope limitations, revision policy
  5. Estimated delivery date — When the work/goods will be delivered

Terms: 50% deposit required to begin work.
       Balance due upon project completion.
       This is a proforma invoice and not a
       request for payment.

Converting Proforma to Final Invoice

Once the client approves and work begins:

  1. Keep the same line items and pricing
  2. Change the document type from "PROFORMA INVOICE" to "INVOICE"
  3. Assign a real invoice number (INV-001, not PRO-001)
  4. Update the date to the current date
  5. Set actual payment terms and due date

Common Questions

Is a proforma invoice the same as a quote?

Similar but not identical. A quote is less formal and may not include all invoice-like details. A proforma invoice follows the invoice format exactly, making it easier for the client's accounting department to process.

Can I use a proforma invoice to collect payment?

Technically no — it's not a legal payment request. However, many businesses use it to request deposits with the understanding that a final invoice will follow.

Do proforma invoices need sequential numbers?

Yes, for your own organization, but they should use a different prefix (PRO- instead of INV-) to avoid confusion with real invoices.
