What is a sales invoice?
A sales invoice is a document that reflects all the information about a sale. The invoice must include the date, the product or service sold to your client, its unit price, quantity, discount if applicable, the type of VAT and the total amount. Also add the fiscal data of both the buyer and the seller.
You are always obliged to issue your sales invoices and include them in your accounting, whether you are a company or a freelancer. Each invoice must have a unique and correlative reference. Remember that the customer can always ask you to send him the invoice. Typically, once the payment is made, you will send it by default.
