We have the warehouse space and readily available labor to receive shipments as small as a few boxes or as large as 40 foot containers. We will help you scale your business without the need to lease your own warehouse and hire employees.


We have accurate and efficient inspection services. From basic exterior carton checks, to detailed unit by unit inspections. 


We offer carton forwarding services (freight forwarding), priced per carton and per pallet. We can palletize and help you save money by transitioning to LTL freight shipments as well as leveraging our UPS’ low shipping rates.

Product Prep

We can make any adjustments needed to your shipments before sending into Amazon FBA. This prep includes labeling, kitting, bundling, photography and more.


We provide additional warehouse storage as needed at better rates than Amazon. Split your shipments by sending part to Amazon, and storing the remainder with us. As the stock on Amazon runs low, we replenish as needed.

Why choose our prep center?

Dedicated Account Manager 

At McKenzie Services, you are appointed a single point of contact and your account manager will learn everything there is to know about you, your business and products so that you aren’t having to re-explain processes and such to multiple contacts at our facility.

Shipment Notifications

Many prep centers require that you input your orders into their system in advance. They then receive against those orders. With McKenzie Services:

  • Carton Forwarding client just needs to enter what cartons are on the way.  
  • Wholesale & OA client’s only need to tell us when pallets are on the way. No need to tell us what the individual items are. Just order your product and we will do the rest!

Insured Inventory
Our insurance covers your products in our warehouse, while many other companies require you to get your own insurance.

Inventory Tracking

Many prep centers rely on google sheets to track orders and create shipping plans. Our proprietary software, EPIC, is easy to use and requires less work on your part. Simply order, and wait for your units to arrive, add your ASINs to our portal, and select which items are ready to ship. You can also download receiving reports if you’d like to reconcile. 

Security Cameras
We have security cameras at each of the doors for added security. Hillsboro Police Department also uses our parking lot for their breaks!

Job Trials

Not sure if you are ready to commit to a prep center? No problem. We offer job trials so that you can test us out.

Automated Billing

All billing is processed automatically. You wont need to deal with invoices or submitting payments. We will send you an email with a billing breakdown for each charge.

McKenzie Services and in particular my Account Manager Hannah, have been invaluable to my business. I used their prep, storage, and fulfilment services and they were always so professional, reliable, and well organised. Their service went above and beyond other fulfilment services I researched and they always provided guidance or advice if needed which was greatly appreciated as an Amazon seller based in Australia. I highly recommend them.

It's been 6 months since I started using McKenzie Services for Amazon Prep services and they continue to do an excellent job even as Q4 starts. The personalized support that Hannah and her team provide is worth any premium they may charge. I don't know how how I lived without them supporting my business. I highly recommend them and wouldn't consider using anyone else.

We've be using McKenzie for nearly one year to help with our online fulfillment and storage. We've been super impressed with the quality of their work, and their commitment to service. I strongly recommend them as a 3PL partner. In particular I'd like to highlight the great value that comes with working with their account managers. We've worked with Hannah, and have been grateful for her 1-on-1 consultation, attention to detail, and overall commitment to helping us with all of our fulfillment needs. Having a single point of contact to help with large and small requests has really made a difference, and has really helped us grow. Again, we strongly recommend McKenzie!
