What is an invoice and what is it for?

An invoice is a mandatory document that companies must issue when making a transaction for goods or services.

Key features of an invoice

  • Mandatory: Formalize a sale or provision of services.
  • It contains key data: Names, NIF, concepts, amount, taxes and dates.
  • It allows you to deduct VAT: It is essential for the accounting of companies and the self-employed.

What is a pro forma invoice?

A proforma invoice is an informational document that details the conditions of a sale before it is made.

Key Features

  • It is not an accountant: It has no fiscal value, but it does have legal value.
  • It includes basic information: Prices, taxes and conditions of sale.
  • Main function: Inform the customer of the details of a potential transaction.

EXAMPLE: If you're negotiating with a customer, you can send them a proforma invoice to agree on terms before issuing the final invoice.

What is a quote?

A budget is a document that indicates to the customer the estimated cost of a good or service.

Key Features

  • Conditional validity: It is only valid when the customer accepts it by signing it.
  • Contractual obligation: Once accepted, prices cannot be changed except by mutual agreement.
  • It makes planning easier: It helps both parties to be clear about costs and scope.

Key difference: Unlike the pro forma invoice, the quote is not legally valid until it is signed.

What is a waybill?

A waybill is a document that proves the delivery of goods or services.

Key Features

  • Optional: Not all companies are required to issue it.
  • Proof of delivery: The customer can sign it to confirm receipt.
  • Does not include tax information: It only details the goods or services delivered.

EXAMPLE: If you deliver an order, the customer signs the waybill as proof that they received the products.

Differences between invoice, delivery note and quote

Proforma invoice vs quote

  • Legal validity: The pro forma invoice has legal validity; the quote only after being accepted.
  • Time of issue: The quote is delivered before acceptance, the proforma invoice at a later stage.

Quote vs delivery note

  • Objective: The budget details costs; the waybill accredits deliveries.
  • Contents: The waybill does not include prices or taxes, the budget does.

Waybill vs invoice

  • Mandatory: The invoice is mandatory; the waybill is not.
  • Purpose: The waybill proves the delivery; the invoice formalizes the sale.
