Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBizyness turns every Shopify order into a compliant invoice and every refund into a credit note, automatically. Your invoices are ready for mandatory e-invoicing through a certified partner platform. VAT is calculated on every B2B and B2C order: France, EU, OSS, IOSS and reverse charge. Track expenses and suppliers, and send your accounting to your accountant with a one-click export.
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.
