description: "Quittus is built for stores invoicing under French or United States rules. Every paid order becomes a compliant invoice, every refund becomes the matching credit note, numbered sequentially as the law requires. You enter your legal details once and stop thinking about it. Invoices carry your logo, handle multiple tax rates, and French invoices embed Factur-X data. At month end you hand your accountant one file instead of a folder, and an audit finds no gaps in your numbering."
