About FlatInvoice ‑ Auto Invoices

Invoices email themselves the moment an order is placed — every order, every document, nothing to configure. A guided setup adds a Download-invoice button right inside Shopify's own order emails — copy, paste, done. Unlimited invoices, packing slips, receipts, and credit notes, each carrying your logo, with your brand color picked from it in one click. Tax-ready with a VAT/GST tax ID line and sequential numbering. Every invoice shows exactly what the customer paid at the time of the order.
