In most cases, yes. You will need to include either the original invoices or certified copies, depending on the rules of the country where the refund is being requested. These invoices must meet specific criteria:

• Clearly identify the buyer (your business name),

• Show the nature of the goods or services purchased,

• Include the VAT rate and amount paid,

• Be dated and sequentially numbered.

It is highly recommended to keep scanned copies for your records and, where possible, to translate invoices into French or English if they are in another language. Some jurisdictions may reject incomplete or unclear documentation.
