Fast and effective, Dan was able to resolve my issue!

I really like this app. It works well for our shop and doesn't overwhelm buyers with huge popups during checkout. It's noticeable enough for them to see other suggested items but isn't bothersome.
— The Bead Obsession
We love SellUp, easy to use and definitely increased our AOV.
— WoB
very easy UI to get a hold of, does everything my company needs to do regarding cross-sells, cart upsells and more. Highly recommend to anyone that needs something to start them off

Good, they handed my supportcase fast :)

Im Zeitraum, in der die App installiert war, waren ca. 300 Sitzungen laut Shopify auf der Produktseite. Abgebucht wurde dann direkt die Gebühr für 500+. Das ist mir zu Intransparent, wie die App die Zahlen erfasst. Leider keine Empfehlung
— Dayfuel
Die Art der Abbuchung ist nicht transparent. Obwohl die App deaktiviert ist wurden innerhalb von 1h 300 Views erzeugt. Laut Entwickler wird nach Anzahl der Views abgerechnet. Für mich ist das fast Betrug und die App sollte als unseriös gemeldet werden.
— Collory
We are not getting any upsell orders!!
— Official KBeauty
Received a bill for nearly $500 that was for 2 orders placed on my site. Unbelievable. I did not know they were going to charge or bill me for these transaction fee's.
— AED On Sale
Can't even begin to test the interface out if I don't provide payment information? What?
— Vintage Source
There's no way to save a new upsell anymore.
— SYNTH Carbon
I installed the application, and it's quite easy to use. However, the add-ons take too long to load on the product page (On average, it takes 30 seconds).
— Esme & Odrilia
Received 666 views in 30 days - and was charged $29.99 (that's the rate for 5,001 to 10,000 views in a month) - should have been charged $14.99 (not that we got any revenue from the upsell app) - I really cannot be dealing with these apps that overcharge v stated pricing then make it impossible to contact them. Suggest you look elsewhere for an app that charges the stated monthly fees
