What is an estimate?

An estimate is a commercial proposal offered to a customer. This proposal includes detailed information about the product or service offered, unit price, quantity, discount if applicable, the type of VAT and the total amount. Also record the identifying and fiscal data of both the buyer and the seller.

Difference between estimate and invoice

An estimate is a proposal that, if accepted by the customer, we can convert to invoice. The estimate, unlike the invoice, has no fiscal validity nor affects your accounting. For this reason, its serial number has a different format than the invoices. In addition, an estimate can be modified without problem if we negotiate with the client. Instead, an invoice is a final document that directly affects our accounting. To cancel an invoice, we will have to issue a credit note to cancel it.
