Wir brauchten eine Sperre für Schweizer Rechnungsadressen, die nur bei rein digitalen Bestellungen greift. Die Bedingung dafür gab es noch nicht, also haben wir den Support gefragt: Antwort nach 30 Minuten, das fertige Feature noch am selben Tag released. Die Regel läuft exakt wie gewünscht, getestet mit Karte und PayPal. Besserer Support ist kaum möglich. Klare Empfehlung.

The app itself is feature-rich and has been very helpful for managing shipping restrictions and preventing problematic orders. It's easy to use, flexible, and backed by a team that truly cares about its users.

Support was responsive and quickly implemented support for validating a new early access Shopify field to collect a required ID number in certain countries. Really appreciate the fast turnaround.

Exactly what we we're looking for, since we can't use the checkout blocks as we're not on Shopify Plus.

App funktioniert wunderbar, der Support ist schnell und zielführend, haben 2 Funktionen angefragt, die innerhalb kürzester Zeit einprogrammiert wurden (Rules für billing address, war vorher nur für shipping verfügbar).
