What stands out most is the combination of technology with strong, hands-on account management. We initially started with Quartile for Amazon DSP, but the quality of service and professionalism gave us the confidence to expand across Amazon Seller & Vendor, Meta and Google.

Our Account Manager, Cesar Barbosa, has been particularly valuable. He takes the time to understand our strategy and commercial objectives, provides constructive recommendations, coordinates effectively with the relevant channel specialists, and ensures agreed actions are followed through. The structured weekly reporting and progress reviews give us clear visibility of performance, priorities and next steps.

Overall, the responsiveness, professionalism and coordination across the wider Quartile team have made managing multiple advertising channels considerably more streamlined. Review collected by and hosted on G2.com.

One area that could be improved is having even greater visibility into the reasoning behind some of the automated optimisation decisions, particularly when managing larger advertising budgets. More detailed insights into what the technology is changing and why would help us align the platform’s optimisation more closely with our wider commercial strategy. That said, our regular communication with Cesar and the wider team helps bridge this gap effectively. Review collected by and hosted on G2.com.

If you are looking for a team that actually listens to your vision and delivers explosive results, look no further than Quartile. I’ve only been with them for a few months, and my company, B&KM Farms, is already doing almost 3X the volume we did last year. The growth is just insane.

It all started with Juliano Oestreich, my onboarding specialist. He was absolutely amazing and made the transition seamless. He really took the time to understand what I needed, showing the kind of flexibility you just don’t find with other agencies.

Now, I have a "long-term team" that I truly consider part of the B&KM family:

Leonardo Azevedo: He is remarkably good at his job, but more than that, he’s just so personable and friendly. It makes the work day so much better when you’re working with people who genuinely care.

Ligia Nemeth: A total go-getter and the best cheerleader you could ask for. Her energy is exactly what a growing business needs.

Adrienne Labes: A true professional through and through. She is so kind and keeps everything running at the highest level.

They are so communicative and knowledgeable, but most importantly—they actually deliver. If you want to see the proof, look up B&KM Farms on Amazon or our website. The results speak for themselves. I can only imagine what we’re going to accomplish by the end of the year with this crew in my corner.

Thank you, Quartile, for taking my vision and running with it! Review collected by and hosted on G2.com.

That I wasn't able to find them earlier. They really are so fantastic. They just need to advertise more so people like me don't have to wait so long;) Review collected by and hosted on G2.com.

What I find most valuable is the granularity Quartile allows for targeting and budget allocation, and—most importantly—the support from the Quartile management team. Review collected by and hosted on G2.com.

The reporting dashboard feels a bit clunky, and if the AI decides a keyword or target isn’t performing efficiently, it will significantly reduce the bids. There are workarounds for this, but they usually require extra support from the management team to set up and structure properly. Review collected by and hosted on G2.com.

It's very new to us, but so far nothing negative. Review collected by and hosted on G2.com.

I really appreciate how responsive the team is, and that I’m not constantly being switched between different people. I love that I’ve been able to work with the same people consistently. Review collected by and hosted on G2.com.

I really can not think of anything I dislike about the Quartile team Review collected by and hosted on G2.com.

We have been working with Quartile to manage our Amazon account, and the experience has been excellent. Their team provides outstanding service, taking the time to truly understand our goals and tailoring strategies to help us achieve them. They are proactive, responsive, and highly knowledgeable about the Amazon marketplace, offering insights and solutions that have had a real impact on our business. Communication is always clear, and they make sure we are updated every step of the way. We highly recommend Quartile to anyone looking for a reliable and results-driven Amazon partner. Review collected by and hosted on G2.com.

The only minor downside is that raw data isn’t always shared directly, which can make it a bit harder to analyze certain metrics on our own. Despite this, their insights and strategies have had a meaningful impact on our business, and we would still recommend them to anyone looking for a results-driven Amazon partner.

In 2.5 years of selling on Amazon, the first time I truly felt relief and actually started sleeping well was the moment I saw what Quartile software is capable of doing.

Like many other sellers, I started by managing PPC myself, and things were going okay. But as my account grew, everything changed. At some point, I was looking at nearly 100 SKUs, and it became absolutely impossible to optimize everything manually or rely on the basic tools available on the market.

I came across Quartile after trying 2 different Amazon PPC agencies, and the last experience was a complete disappointment. After six months, there was barely any improvement in TACOS. At that point, I decided to give Quartile a try and three months later, it delivered exactly what I had been hoping for. My account is now organized and structured, metrics are optimized based on conversion, and my TACOS dropped from 22% to 13%!

What I love most is how the process feels. PPC is finally easy! It truly feels like you’re delegating a huge, stressful part of your business to a team of professionals. They take care of all the heavy lifting such as managing the software and handling time-consuming routine tasks. You finally get the space to focus on strategy and growth. For the first time in a long while, I have the time and energy to step back, see the bigger picture, and make better decisions.

The professionalism and seriousness of the team are impressive, and my account manager, Cesar Barbosa, is absolutely the best. I genuinely feel like I’ve found someone who is part of my team, not a third-party service. A partner who listens carefully, makes thoughtful decisions, and truly cares about our shared success.

The first 1.5 months are stressful because the system needs time to learn what’s actually working. In the beginning, your numbers may look a little worse, and you have to trust the process and be patient. Not always easy! But as soon as the system has enough data, it only gets better.

I appreciate the friendliness of the team and how easy they are to work with. They have been transparent and honest throughout the process, and they followed up with a clear, well-thought-out marketing plan that inspired confidence. Review collected by and hosted on G2.com.

The initial startup phase was a bit bumpy while goals were being clarified and the learning curve was worked through. However, the team quickly identified our needs and adapted. Once those early hurdles were resolved, I have genuinely enjoyed working with Quartile. The challenges were not Quartile-related but rather tied to how Google ingested the data.

I like that Quartile meets me where I’m at. They’re experts in the field, but they’re also willing to work with me on the basics of setting up my Amazon store. They consistently offer helpful insights on ways to improve the store, assist me with inventory issues, and suggest product page improvements. Review collected by and hosted on G2.com.

We’ve been very happy with Quartile and with the partnership overall. The main area I’d suggest improving is offering more benchmarking against similar brands, which would help us better guide longer-term growth on Amazon. Review collected by and hosted on G2.com.

I love that Quartile has been wonderful for my business growth and actually given me results, unlike other businesses I’ve tried before. It helps make every dollar count, offering a better return on ad spend, especially with our very low margins and limited advertising budget. They are interested in our business, having regular meetings, and are there for us, not themselves. They help us promote new products, stay away from ones we don’t want to promote, and are just very friendly, easy to reach, and easy to talk to whenever a need comes up. They have proven to be knowledgeable in everything they do, and I look forward to continuing working with them. Review collected by and hosted on G2.com.

it would be nice if I would have heard about Quartile years ago, I could have saved a lot of money over the years Review collected by and hosted on G2.com.
