Die App funktioniert super! Durch den Support mit Mira konnten wir innerhalb kurzer Zeit die App (5 Min) einrichten und mein Problem lösen. Ich habe viele langjährige Kunden, die früher gerne mit der Zahlungsart "Kauf auf Rechnung" zahlten, dies konnte ich leider mit Shopify so nicht umsetzen. Dank der App wird diese Zahlungsart nur Kunden angezeigt, die einen bestimmten Kunden-Tag enthalten. Problem gelöst und meine Kundinnen und Kunden freuen sich.

TL;DR: The Bundlex developer had me up and running in minutes after a minor setup confusion on my end. The app is intuitive, easy to use, and a great way to boost AVO with a smooth customer experience. Highly recommend!Full Review-First, the support is amazing. I had some initial issues setting up because I didn’t fully understand how to link the Bundlex bundle to the product (totally on me!), but the developer responded and got me sorted within minutes.Once you get the hang of how bundle apps work, the interface and features are extremely intuitive and easy to use. I would definitely recommend BundleX to anyone looking to increase their average order value and create a friction-free shopping experience for their customers!

Ich habe viele langjährige Kunden, die früher gerne mit der Zahlungsart "Kauf auf Rechnung" zahlten, dies konnte ich leider mit Shopify so nicht umsetzen. Dank der App wird diese Zahlungsart nur Kunden angezeigt, die einen bestimmten Kunden-Tag enthalten. Problem gelöst und meine Kundinnen und Kunden freuen sich.
