4Phones España S.L.

Very good support always fast and happy to help. The chat support works really good. we had a problem with the first sync where not all info was imported, but they resolved it quickly. 5 stars

The app works good. We use it in 3 different shopify shops, soon a 4th. The support is amazing too, they fixed a problem for us in 1 day and are super friendly. Really good support

These guys have some of the best support i've seen from all apps on Shopify. Also I tested multiple return apps, this is definitely the best i've seen.

The app helps us setting discount levels for specific customers. Its not very easy because we have over 9000 products and we dont want to manage them one by one, but we were able to group products and put a % on group level. The only thing we didnt figure out yet is how to do product promotions when a whole sale customer has a discount % attatched to his profile. It seems the system doesnt know how to use 2 discounts on 1 product.
