Easy to learn and use, helped us scale fast We started using Quartile in July (5 months ago) and it has worked so well for us. We had previously been managing individual campaigns on Amazon manually in the advertising console. Quartile's software is pretty easy to use and has helped us scale fast and lower our ad costs.

Communication is key. Ever since I started working with Everton Konrad at Quartile, I've felt like I can reach out anytime with any question. Everton is quick to respond. I can't say this is always my experience with all companies I work with. He is also consistently analyzing our account and helping us achieve the best results with the least amount of ad spend. I would highly recommend working with Everton Konrad at Quartile.

Total Disappointment I used Quartile before Covid and they were very effective. I have run my own Amazon PPC for a while and had ACOS running at around 40%. I went back to quartile in order to try and bring down my ACOS and increase sales. They were confident that they could bring my ACOS down into the 20% range but said that they expected it to take a month or two before their algorithm really kicked in. I used them for a total of 5 months and, during that time, my ACOS hovered around the 70-80% mark. We had weekly meetings at which I begged them to bring down the ACOS as I was simply losing money on every sale. They constantly promised to do so but month 5 had ACOS running at 75%. I gave notice and stopped using them. They ignored the notice I'd given them and continued to charge me after termination of contract. I am so disappointed with the results I got from them and cannot believe the way that they treated me after termination. This was a company who's AI algorithm might have worked in the past but obviously cannot cope with the way Amazon currently runs its advertising. Losing me thousands of $ was bad enough but then the way I was treated afterwards was appalling. I certainly would never recommend them again and would strongly suggest that potential customers look elsewhere.

Intelligent staff Working with Gus has been wonderful so far. He has a true knowledge of the business and provides thoughtful and strategic suggestions to optimize and grow our brands.

The algorithm is a black box The algorithm is a black box. You don’t know why bids are changing or which campaigns/products were going to be pushed aggressively. Everyday was a surprise to see what products had a disproportionate amount of ad spend for the previous day. I couldn’t effectively manage the algorithm based on my products margins and inventory position. Sometimes the algorithm would stop spending on certain campaigns altogether by reducing bids to 2 cents. I had to relaunch those campaigns. By the end I was spending similar amount of time trying to manage the algorithm as I did on managing my PPC before.
