Amazon FBA Prep Service Fees Explained

Most Amazon FBA prep centers charge a per-unit preparation fee for standard items.

For standard-size products, the typical range is approximately:

• $1.00 per unit minimum
• $1.50 – $2.00 per unit is common for many providers

This base fee generally includes the most common preparation tasks required by Amazon.

The standard rate usually covers:

• Receiving shipments from retailers or suppliers
• Basic inspection of products
• Applying Amazon FNSKU labels
• Poly-bagging when required
• Preparing cartons for shipment to Amazon fulfillment centers

A flat per-unit rate makes it easy to work prep into your numbers when you source inventory.

The Prep Cost Estimator runs this math for your own volume. Enter the units you send in each month, then pick your sourcing model (wholesale and private label, or online and retail arbitrage) and your item size. You get an estimated monthly prep cost with a typical range and a per-unit price range. It also estimates the hours and materials it would take to prep the same units yourself, so you can decide whether outsourcing makes sense. No email is required, and the result is a budgeting estimate, not a quote.

For many years, Amazon offered a labeling service that allowed sellers to ship certain wholesale products directly to Amazon without applying FNSKU labels themselves.

In January 2026, Amazon discontinued this labeling service in the United States. Sellers now have to finish all required labeling and packaging before inventory arrives at an Amazon fulfillment center.

Because of this change, more sellers now rely on prep centers, especially those shipping wholesale inventory or products straight from suppliers.

Prep centers typically base their pricing guidelines on Amazon’s own FBA size and weight classifications.

Amazon publishes specific dimensions and weight limits that determine whether a product is considered standard size or oversized. These classifications affect Amazon’s own fulfillment fees and often influence how prep centers structure their pricing.

Oversized products need more handling and larger packaging, so prep centers may charge higher per-unit fees for items outside standard-size limits. The estimator’s oversized option adds this extra handling to the per-unit rate.

Fragile items that require additional protection may also increase the prep cost. For example, bubble wrapping and extra boxing may add $1–$2 or more per item, depending on how much protection the item needs.

Some products must be bundled or packaged together before being sent to Amazon.

Prep centers often charge an additional per-unit bundling fee when multiple items must be packaged together as a single listing.

The extra charge is often small, sometimes as little as $0.25 per added item, but the exact fee depends on how complex the bundle is.

Prep centers generally follow one of two pricing models.

Many prep centers charge a single per-unit price that includes most standard preparation steps. This model is simple and predictable because the cost per unit stays the same. The Prep Cost Estimator is built around this model.

Some providers break out each service as a separate fee. Under this model, tasks such as labeling, poly-bagging, bundling, inspection, or special handling may be billed individually.

This gives you more flexibility, but it makes the total cost per unit harder to estimate.

Some prep centers adjust pricing based on volume.

Larger sellers may qualify for lower per-unit rates once they reach certain volume thresholds.

For example:

• First 500 units at one price
• Lower pricing for higher volumes

Some larger prep centers require clients to meet a minimum monthly volume or spending threshold. These minimums help providers maintain predictable workloads and prioritize high-volume clients.

A small number of prep centers operate using a membership or subscription model.

In this model, sellers may pay a monthly fee that includes a certain number of units prepared. Once the included units are used, additional units may be billed at a lower rate.

Prep centers often provide short-term storage for inventory that is being processed.

Many providers allow products to remain in their facility for up to 30 days without storage charges while the items are being prepared for shipment to Amazon. After that, storage fees may apply.

In the FBA prep industry, storage pricing is commonly structured per pallet per month, although larger warehouses and third-party logistics providers may use other pricing models based on cubic footage or warehouse space.

In most cases, the cost of receiving shipments from retailers or suppliers is included in the standard prep fee.

Some situations add receiving charges, such as:

• Breaking down large pallet deliveries
• Receiving shipments that require special handling
• Container unloading

When shipments arrive in large freight containers, prep centers often charge either a per-container fee or a per-unit unloading fee because containers must typically be unloaded manually.

Once products are prepared, they must be shipped to Amazon fulfillment centers according to the shipment plan created in the seller’s Amazon account.

Today, most prep centers operate as authorized users within their clients’ Amazon accounts, so they can create shipments and print labels directly in Amazon’s system.

Many also use inventory management platforms, which give sellers a dashboard for tracking inbound shipments and billing instead of spreadsheets.

These systems allow the prep center to manage the entire preparation and shipping process once inventory arrives.

Many prep centers offer services beyond basic preparation.

Common additional services may include:

• FBM order fulfillment
• product photography
• returns processing
• container unloading
• wholesale shipment preparation
• private label inventory handling

Some providers may also offer extended warehousing or third-party logistics (3PL) services.

Prep pricing varies by provider, product type and the services you need. When you compare prep centers, look past the per-unit rate to storage policies and monthly minimums, and ask about turnaround time before selecting a prep partner.
