The three founders are long time Amazon sellers with years of experience and hundreds of thousands of items prepped and shipped between us. Currently we are working on our private label and branded bundles to grow our Amazon business and we do not do Online Arbitrage. We are doing millions of dollars in sales on Amazon and Walmart and would like to help you get there as well.

We are now operating our business from a 10,000 square foot warehouse and growing. We have all the machines and infrastructure in place to help you grow your business and take you to the next level and give you a quick turnaround time from when we receive the items to prepping and shipping to Amazon/Walmart.

With starting this tax free prep center, we set out to make the best experience for our clients as possible. We have used a prep center in the past and there are always pros and cons but how do we eliminate those cons as best we can??

We have spent months researching, touring other warehouses, interviewing warehouse owners and future clients, and preparing for our tax free Prep Center and we are confident that we can deliver the best service out there.

The main pain points we found that other prep centers consistently had in common is that people want straight forward pricing, quick turnaround time, and excellent response time/customer service when they have a question. We aim to fix all those issues.

Proven Prep Center will use google sheets to upload your items that you are ordering throughout the week. We will update your spreadsheet as we check items in and as we open boxes to ship. Inventory Lab will be required for this or Scan Power so we can do this efficiently for you. Proven Prep Center will also be checking your Asins and items to make sure they match or are still profitable before shipping them into Amazon/Walmart.

Proven Prep Center will also have someone on staff during working hours designated to take your calls, texts, and emails so we can get you answers ASAP and not slow your business down.

Proven Prep Center also plan on shipping major sellers inventory out twice a week if possible and once a week for others on set days so you can count on your stuff going out regularly.

You will not regret working with Proven Prep Center and would love to talk to you more about what we are doing. Please, schedule a call by filling out the form and we will be in touch with you 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.
