We loved our onboarding experience with Atomix and are currently working with them to fulfill our 3pl needs. Their dedicated Slack channel team (shout out to Zainab and Preston) was crucial in helping us transition warehouses while simultaneously fulfilling orders! Highly recommend this company!

Atomix makes my life so much easier
Atomix makes my life so much easier. Our quickly scaling startup needed a partner who could provide excellent communication and fulfillment, and we have had only positive experiences with Atomix since we started working with their team. Our account managers are incredibly helpful and attentive, and our orders go out quickly and correctly every day. I can't imagine rating our experience anything less than five stars!

Not a 5 star service
I really wanted to love them and leave them a 5 star review as they have asked. Just never got to doing that at the start of working with them, and then things started piling up.
I had a very low volume store, so they were probably not making much money with me and not super motivated, but still I don't think these things are acceptable in any business.
They have a portal and a dedicated slack chanel. What happened initially no one set me up with a portal and slack chanel took days to get someone to reply to messages. They have a Shopify integration and are supposed to pick up orders automatically. In reality I had to ping them for unfulfilled orders in slack (days to get reply=shipping delays).
I could never figure out the billing, sometimes I was billed for shipping more than I had orders (like I said very low volume).
There was another instance when my account got locked for no payment, but there wasn't any invoice or any way to pay sent to me and it took days to get them to look into the matter.
When we finally parted ways, it took them about a month to get my inventory sent out. And they only sent half of it, didn't include my branded packaging materials either.
So, that's the story. Sorry I can't make this 5-star, Atomix.
Update:
Thank you so much for getting back to this review 3 years later.
I have actually heard from the founder back in Aug of 2023 and here's what he wrote:
"Ah. I'm so sorry. My inbox is currently 24,326 unread (which is my own problem to manage) but I am genuinely apologetic you didn't even get that level of a response from me.
Let me speak with the team today. I will see where the status is and update next week."
3 years later, he's still checking. I have never received any credit for a missing inventory or packaging materials.

Thank you for this, and we are genuinely sorry. You wanted to love working with us, and instead you got a missing portal setup, slack replies that took days, a Shopify integration that did not pull orders the way it should have, billing you could never make sense of, an account locked without an invoice or any way to pay, and an offboarding that took a month and still went out incomplete. None of that is acceptable at any volume, and we will not pretend otherwise.
The idea that a smaller store deserves less attention is exactly what we have worked to eliminate, and several of our new written guarantees speak directly to what you experienced, with automatic credits when we miss, for every client regardless of size:
100 percent On Time Shipping, so orders do not sit unfulfilled waiting on a slack reply.
100 percent Billing Accuracy, down to the line item, so you are never charged for shipping you did not have and never left guessing about an invoice.
100 percent Inventory Accuracy, so your stock, including branded packaging, is accounted for to the unit and credited at full cost if anything goes missing in our care. Sending back half your inventory is precisely the failure this covers.
We hate that we lost someone who was rooting for us. We took this kind of feedback seriously enough to put real accountability in writing, and that is the standard every client can now hold us to.

Has a lot of issues to work through...
I am the owner of a small skincare brand, 2 SKUs. I interviewed several 3PLs because I needed batch management, and my old 3PL - a large outfit - does not yet offer FEFO. I went with Atomix because of the reviews, and because it seemed to offer both flexibility as well as the ability to scale, even though its pricing is premium compared to some of the other companies I spoke to.
Unfortunately, Atomix did not deliver. There were three major issues and a host of smaller ones.
1) Somehow, all major carriers with the exception of UPS do not have reliable service in the Milwaukee area. We cycled through USPS, DHL, and Fedex. There were lost packages, packages where the tracking did not appear for days on end, delayed packages, so customers were emailing our customer service pretty much every 2 or 3 days, at a rate I did not see with my old 3PL. We eventually had to shift to UPS because it was the only reliable service, and I needed to provide my customers with a good experience. Note that the pricing quoted during the pitch is USPS prices, so once you switch to UPS Ground, your shipping costs go up >2-3x the quoted shipping cost to approximately $12-$18 for a 4 ounce package with dimensions ~5x5x6 (and up to $80 for Hawaii). Of course, you can not switch and stick with USPS, but that means dealing with lost items and lost tracking ALL the time.
2) It did not have the technology / platform to automate most things, so a lot of things were still pretty manual and human-dependent. Atomix did not have enough staff to sufficiently and competently deliver on the more customized service it promised (and appear to charge for). Towards the end, I got a customer service rep who was great, but she isn't a system. She's just a human being, and she could not make up for the general lack of bodies. For example, whenever any of the key staff gets sick, things fall apart for a few days. They also don't have a customer service ticketing system, so requests (especially pre-this particular rep) often were lost, requiring following-up on your part.
And due to the manual aspect of their system, they could not keep track of inventory - leading to inventory levels dropping from >100 units to 0, which obviously created problems for me as I was under the impression I still had stock.
3) International shipping gets lost A LOT, and neither Atomix or the carrier they use tried to figure out what was going on. Atomix insisted they shipped out the packages, and the carrier insisted they didn't receive them at their facility...
With Atomix, I've experienced difficulties on an almost weekly basis - shipping being mapped to the wrong options, duplicate orders being sent out on a regular basis (which sucks because repeat customers no longer have to refill as quickly), pricing being 2x what was quoted because they forgot to sign me up for an international shipping service on their end, systematic lost packages, double charging on the bill, tracking issues, surprise charges that aren't in the contract. Though they've corrected some of these issues, it means that I take time out of my business to focus on logistics and comb through the invoice.
If I hadn't worked with my old 3PL in the past, I might have thought this was par-for-course for a 3PL, but I had. Yes, you get an anonymous customer service rep at my 3PL instead of a person you know, but you don't really need to chat with that anonymous rep, because their systems catch most errors or provide relatively simple remedies. Whereas you constantly have to reach out to your Atomix rep because something had gone wrong. I've since gone back to my old 3PL, but I wanted to leave this review because I think it's important to let other small business owners know.
Good idea, bad execution.

We really appreciate you taking the time to write something this detailed, and we want to be upfront that this review is from 2023 and a great deal has changed since then. That does not undo your experience, and the problems you describe, lost and untracked packages, inventory that dropped from over 100 units to zero, duplicate orders going out, double charging, surprise fees, and pricing that landed at multiples of what was quoted, are exactly the failures that pushed us to rebuild how we operate.
Rather than ask you to take our word for it, we have put the fixes in writing as guarantees for every client, with automatic credits when we fall short:
100 percent Inventory Accuracy, so your stock is tracked to the unit and never silently drops to zero, with full cost credit for anything lost or damaged in our care.
100 percent Order Accuracy, so duplicate shipments and wrong shipping options are on us to make right, not on you to catch.
100 percent Billing Accuracy, down to the line item, so double charges and surprise fees that are not in your contract do not happen, and a $25 credit applies to any incorrect line item.
100 percent On Time Shipping, backed by credits when we miss.
You had a clear point of comparison from your previous 3PL, and you were right to expect systems that catch errors rather than a single great rep carrying the load. Building that reliability into writing, for brands of every size, is exactly what we set out to do. Thank you for the honest feedback that helped get us there.

So far so good with Atomix Logistics
So far so good with Atomix Logistics. We just started up service with them just in time for the Black Friday rush and while we have a few wrinkles to work out they have good systems in place and very good support.
Communication is constant with our Micro Pod team. Having a dedicated team works really well so you are always working with the same core group and not having to re-educate new people about your specific needs for your products or issues that need to be fixed.
At this point we would definitely recommend Atomix if you are looking to scale your ecommerce fulfillment.

We love Atomix
We have been using Atomix as a third party logistics company for almost a year now, and I have been consistently impressed with their level of service. They have always been prompt to respond to our requests and have been very effective at managing our inventory. Their team is professional and friendly, and they have helped us to streamline our parcels. I would highly recommend Atomix to anyone looking for a reliable and effective third party logistics company. They have been an integral part of our business, and we look forward to continuing to work with them in the future.
