Standard
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDesign invoices without code, with your logo, colours and fonts, previewed exactly as they print. Then each one is treated as the legal record it is. Every document takes the next number in an unbroken sequence and is frozen when it issues. Refunds get their own credit note; the original is never rewritten. Send them yourself or automatically, PDF attached and delivery tracked.
Simple Invoice creates a proper PDF invoice for every order in your store, so you never have to build one by hand or dig one out later for an accountant. Invoices are generated the moment an order comes in, numbered in sequence with no gaps, and filled in with your company name, address, VAT number and logo. Download the PDF whenever you need it, or open a prefilled email to the customer with one click.
