I like how they have an online portal to keep track all their inventory, so it's easy for me as well my customers when we place orders or want anything from them! The only downside i can see would be if you're not familiar with this type of business system then there might be some difficulty learning everything at once but other than that nothing comes up in mind right now!! Overall great service provided by cer group. Great customer support team who are willing help any time no matter what day/time its available 24hrs 365 days! They provide us excellent prices compared to others which makes our job easier doing wholesale ordering instead of going through many different suppliers just because price difference between each supplier isn't much low enought!!
