Frequently Asked Questions
What are your prices?
We have several account types to choose from to fit your needs. All our pricing is listed on our services page.
FBA Prep (Wholesale and Online Arbitrage)
With FBA Prep, you should expect to see three types of charges for each shipment — Receiving Charges, Prep Charges, & Shipment Processing charges.
We charge a receiving charge for each package or pallet we receive. This fee covers the cost of receiving, scanning, sorting, and handling the packages before being processed for FBA.
Our base price (Standard Unit Processing Charge) for prep is based on the number of units in the shipping plan. We give a volume discount for shipping plans with more units. The base price covers adding the unit to the shipment and includes an FNSKU label if applicable. No discount is given for units that are already labeled or use manufacturer barcodes. Additional charges, like bubble wrapping, bundling, oversized units, etc., are added on to the base price.
For small shipping plans (fewer than 40 units), we charge an FBA Shipment Processing charge. If the shipping plan has 40+ units, we waive the processing charge.
We do not charge for reused materials like outbound boxes and packing materials for FBA shipments. We will always try to reuse outbound shipping boxes as our first option. If we don’t have the appropriate sized box for your shipment, we will use new boxes and assess a charge for them.
We almost always have used packing materials, like air pillows and paper, that we can use for FBA shipments.
For customers who order products that come case packed and are already prepped and labeled for FBA, we can store your inventory and forward the cartons to Amazon as required. This means we don’t open your cartons when received. Instead, we put them directly into storage. When you are ready to have us send some cartons to Amazon, we will attach the shipping and box labels to the outside of the cartons and release them to the carrier for shipping.
You should expect to see at least three types of charges for carton forwarding services —receiving charges, storage charges, and forwarding charges. There is a minimum charge of 5 cartons for each shipping plan.
If you would like us to open and inspect the units, we can. We charge an inspection fee for each unit. If any prep or other services are required, FBA prep charges will apply.
Are there any items you will NOT accept?
Prep Ninjas reserves the right to refuse to accept or process any product or shipment we deem dangerous, excessively laborious, legally questionable, or that we are not properly equipped to process. These products include but are not limited to:
- Customer Returns
- FBA Removals (without express permission)
- Grocery Items purchased through Online Arbitrage or Retail Stores
- Meltable or temperature-sensitive, regardless of the time of year
- KONG Company brand pet products
- Sees Candies brand products
- Used Products
- Dangerous products like corrosives, solvents, fuel, fertilizer, pepper spray, bear repellent, or firearms.
- Overly fragrant products that do not come in pre-sealed containers like essential oils, perfumes, sachets, or candles.

- Products larger than 24 inches on their longest side (without express permission)
Received products classified as Unacceptable are subject to a Non-Compliance fee of $2 per unit and must be removed from Prep Ninjas warehouse within seven (7) calendar days at your expense. If the products are not removed by the deadline, we will consider your inventory abandoned and reserve the right to dispose of the items.
Are there any other charges or fees I should worry about?
Our goal is to process your shipments as quickly and accurately as possible. In order to do this, we require your help. We’ve outlined our expectations in our Terms of Service. Not following the Terms causes additional labor, delays, possible safety consequences, and many other situations that prevent us from providing fast and accurate service. Because of its importance to providing good service, we’ve established penalties for non-compliance. These penalties are assessed in addition to any standard fees for Inbound shipments, Outbound Shipments, Storage Fees, or other charges. You can download the list by clicking here.
How will I be billed for your services?
We require our clients to list a card on file. You will be billed for the services at the time they are completed. You can access your invoices/billing history on your Prep Ninjas dashboard.
Do you prep and list used books?
We do not offer prep services for used books.
What does tax-free mean?
When you purchase online and ship to our center in Oregon, you don’t have to pay sales tax like you would in most other states. The money you save on sales tax helps to offset the cost of outsourcing your inventory prep. That means you can grow your business even faster. For example, the average sales tax rate is around 8%, which means you’d be paying $1.60 in tax for a $20 item. Some of our plans could cost less to process an item than the sales tax would have been!
What is the turn around time for prepping?
Turnaround time varies, but most orders are completed within 24-72 business hours. Turnaround times can be longer during peak periods such as before Prime Day and Q4.
Do you work with International Sellers?
Yes, especially if you are purchasing goods in the US and shipping them to our center. We accept international shipments sent to us. We do not broker or process the paperwork involved for importing/exporting goods at this time. We only accept payment in US Dollars.
Do you work with new Amazon sellers?
We currently only work with sellers who have been actively selling for over 12 months and have a customer feedback score of 90% or higher. We are looking for ways to make working with new sellers more smooth and efficient. Once we do, we will notify our mailing list and announce any openings.
What kinds of "hazmat" items do you accept? Cosmetics and batteries too?
Products that are or contain batteries such as toys or power tools are accepted, though we do not accept products with lithium-ion batteries for long term storage. Cosmetics that are classified as hazmat are accepted as well. Products that require specialized storage and equipment such as fuels, solvents or corrosives are NOT accepted at this time. Products need to follow Amazon’s temperature sensitive requirements here as well. Because they require special handling, Hazmat Shipments are subject to additional service charge of $5 per shipment. We also require user permissions to your Seller Central account to complete HAZMAT shipments.
Do you accept and ship pallets?
Yes. We accept deliveries between 9am and 4pm, Monday through Friday. We charge a $30 palletizing fee for outbound pallets.
Will you share information about my buys?
Do you have minimums?
We do not have minimums or monthly membership fees. We charge a processing fee for each shipment plus the per-unit prep charges. Please see the Services page for a complete list of our prices.
Do you require User Permissions for Seller Central and Inventory Lab?
Our system (Prep Ninjas IMS) syncs directly with your Amazon account so we do not need user permissions for normal shipments. We can do everything including purchase Amazon Partner Carrier shipping through our system. The only reason we need Seller Central permissions is to complete HAZMAT shipments.
How are the fees for shipping to Amazon calculated and paid?
The shipping labels and charges for your Amazon bound shipments will go through your Seller Central account. We recommend using Amazon’s Partnered Carriers to save on shipping costs. You pay those shipping costs through your Amazon account. For hazmat shipments, or any other shipments that go outside of the partnered carrier, we will invoice you for the incurred shipping costs.
Do you take oversized items?
Yes, we take products up to 24-inches on their longest side for an additional fee. Space is limited, so please inquire prior to shipping oversized items.
Do you offer storage if I need to hold a shipment?
Yes. The first week is free. Starting day 8, we charge $26.48 per cubic meter per month. That is equivalent to approximately $0.75 per cubic foot per month. Our long-term storage charge is $36.48 per cubic meter per month. This applies to storage older than 180 days. Space is limited, so please contact us for availability.
How do you minimize outbound shipping costs?
We try to minimize shipping costs when possible without breaking Amazon’s rules or risking damage to anything in transit. We encourage large shipments and offer volume discounts for larger shipments. We also recommend LTL shipments when appropriate.
What kind of fire protection do you have?
We have alarms, extinguishers, sprinklers, and insurance. We do not store combustible fuels, solvents, or lithium-ion batteries.
Are my products secure?
Yes. Our warehouse is a secure facility and your items are stored with care. We are also insured and have an alarm system.
Did you discontinue your Online arbitrage prep services?
We did put our OA prep service on hold for a time, but we recently brought it back!
Can Inventory Placement save shipping costs?
Amazon’s Inventory Placement fee can save on shipping costs and our turnaround times. Especially when your whole shipment is less than 50 lbs and can safely fit within a large box. A batch split into 3 shipments costs more than 50 small products in placement fees. It’s not as effective with large products that will use more boxes anyway. Also splits are meant to get the product sold and to the customer faster. See more about splits on our blog.
Do you process customer returns or FBA removals?
We do not offer services for processing customer returns or FBA removals at this time.
