PrestaShop invoice is an official, legally binding document created automatically by your store whenever a customer completes a purchase. Think of it as a formal digital receipt. It acts as official proof that a transaction took place, detailing exactly who bought what, when they bought it, and how much money was paid.

This document contains highly specific information required by tax authorities and accountants. It lists your company name and address, customer billing details, unique document number, date of sale, breakdown of purchased items, shipping fees, and exact taxes applied. PrestaShop generates these documents as clean files that can be easily downloaded, emailed, or printed.

For a business owner, these papers are backbone of bookkeeping. They ensure your accounting is perfectly accurate and that you comply with local tax laws. For customers, especially businesses buying from you, this document is essential for their own financial records. Because system builds them automatically based on order data, you never have to waste time manually typing out receipts after a sale.
