Great app to help our customers find the add-on products they're looking for. I really like that I can customise the add-ons for products individually, as this is something that really suits the products I sell. Support has been great- minor issue with my theme stopped SelUp working, but Dan had it fixed quickly giving me peace of mind.

Super app! It's allowed me to create add on products and increase my average order value. Tech support from Dan is second to none. I will definitely be checking out the other apps they have to offer

When contacting support regarding a collection page feature change on the update, Dan from the support team addressed the issue to the developers and kept me in the loop. Within five hours he was able to let me know that the developers had resolved the issue and updated me with a photo of future update plans.

Sell-Up has been great for us. We primarily use it for Add Ons. It was easy to implement and has increased our revenue with Upsells.

Really great addition to the website. I'm not tech savvy but was able to easily get it set up. Due to my store themes the colors weren't very clear but Dan from support fixed that and also improved some other limiting things on my website!

The support team is very helpful and response in a timely fashion. I've been using SellUp App for around one year and the functionalities work well. It's very easy to setup and convenient.
