Love that this works fully offline, exactly what accountants here need. One thing that would make it even more useful for our team: bulk-validate a whole folder of PDF/A-3 invoices at once and export a summary CSV, so month-end reconciliation doesn't mean scanning files one by one.

Offline QR validation that actually feels safe to use on real invoice data. Loved that I could drop in a PDF/A-3 and see the VAT breakdown without anything leaving my laptop.

The offline angle is a nice touch for handling sensitive invoice data, and the UBL 2.1 validation feels solid from what I tested. Wish I'd had this during my last audit headache.
