Amazon Prep


Clients will have their inventory sent out a set day each week*


We are experienced Amazon sellers with a strong track record in private label and branded bundles. We currently operate from a now 13,000 sq ft warehouse, offering the resources needed to help grow your business with a quick turnaround time for prepping and shipping to Amazon/Walmart.


We started our tax-free prep center to provide the best possible experience for our clients. We’ve spent months researching, touring other warehouses, and interviewing owners and clients to ensure we deliver top-notch service. Our goal is to address the common pain points of other prep centers: straightforward pricing, quick turnaround time, and excellent customer service.

At Proven Prep Center, we use Google Sheets to manage your orders and update your inventory. Inventory Lab or Scan Power is required to ensure efficiency. We also verify ASINs and profitability before shipping to Amazon/Walmart. Our staff is available during working hours to answer calls, texts, and emails promptly.

We aim to ship major sellers’ inventory twice a week and others once a week on set days for consistency. We’re confident you won’t regret working with Proven Prep Center and would love to discuss further. Please schedule a call by filling out the form, and we’ll be in touch within 24-48 hours.

Most frequent questions and answers

Please use the contact form to get started and someone will reach out to you through text, email, and call typically within 24 hours.

In order to create your shipments we will need limited access to seller central.

Yes!  We will prep SKU’s with 100 units per shipment at $1.35 and decrease from there based on volume.

Yes we do ship hazmat through UPS Ground

We try to schedule a weekly day that your items will be shipped out so it will be the same every week for you.  If you need another shipment out that week, depending on unit count, we might be able to do that for you.

If it looks like it will cost you too much in shipping because you have too few items, we may pass you (we will reach out to you first through our communication system to be sure).

Larger sellers may be required to ship twice a week for storage space.

Ideally we would like to do a minimum of 100 units per week for you but we are flexible as long as you can maintain the 500 unit minimum per month (there are some exceptions)

Our spreadsheet will will be updated with the items that arrived when we open your boxes or when a shipment is created and left our warehouse.  You can always ask us for an update on your inventory.  Large Sellers may not get an update until we open their packages but those will go out twice a week typically.

Glad you asked!  Yes we are, we use Slack for communication but you can call us at 503-987-8977 or even text us at the same number or you can email us.  I have someone on staff to answer your questions, including myself during business hour so you can get immediate help.
