Where Order Printer Pro does more

Peppol and structured XML formats (UBL, CII) as an add-on.
Very flexible templates, quotes from draft orders, POS printing.
Many published reviews on the App Store.

Where Invoice Autopilot takes a different approach

E-invoice without an add-on: every final invoice is a PDF/A-3 with embedded ZUGFeRD XML – people read the PDF, software reads the XML.
Own number ranges for invoices and credit notes. With Order Printer Pro’s standard PDF templates, the number is derived from the order number according to the vendor.
Automatic credit note per attributable refund against a finished app invoice, with a validation report; already-credited amounts not twice, unclear cases for review.

Which suits whom?

Order Printer Pro suits you if you need Peppol, want heavily customized templates or create quotes and POS documents.
Invoice Autopilot suits you if you want automatic invoices and credit notes as ZUGFeRD e-invoices with their own number range – without an add-on.
