FBA prep cost per unit typically runs $0.50 to $2.00, depending on how complex the prep is. Simple FNSKU labeling sits at the low end. Full kitting, bundling, or fragile-item packaging pushes costs toward the higher end. The real question isn’t just the rate. It’s whether prepping in-house or paying a prep center actually costs less at your volume.
What Drives FBA Prep Cost Per Unit Up or Down
Labeling complexity: A single FNSKU label on a simple product costs less than complex labeling. Covering an existing barcode or applying multiple stickers per unit raises the cost.
Poly-bagging requirements: Items needing a poly bag, a suffocation warning, and precise sealing cost more to prep. Products shipped without extra protective packaging stay cheaper.
Bundling and kitting: Combining multiple items into one sellable unit adds labor time per kit. That raises the per-unit cost compared to prepping single items.
Fragile or oversized handling: Products needing extra cushioning, careful handling, or special palletizing typically cost more to prep than standard-sized, durable items.
Shipment volume: Prep centers often price larger shipments lower per unit. Setup time and equipment cost get spread across more units.
DIY Prep vs. a Prep Center: Where the Break-Even Sits
At low volume, doing your own FBA prep can look cheaper on paper. You’re only paying for materials and your own time. Most sellers see that math flip somewhere around 200 to 500 units per shipment.
Below that range, DIY prep often makes sense. You control the process directly, and the time investment stays manageable.
Above that range, the hidden costs of DIY start adding up. Every hour spent labeling and poly-bagging is an hour not spent on sourcing or marketing. Mistakes also get more expensive at scale. A labeling error caught after Amazon rejects a shipment costs far more than the per-unit prep fee ever would.
The Real Cost of DIY Prep That Rarely Gets Counted
Time doesn’t scale for free: Prepping 300 units by hand takes real hours. That time carries an opportunity cost even if no invoice shows up for it.
Equipment adds up: Label printers, heat sealers for poly bags, and palletizing tools all cost money upfront. That’s before you’ve prepped a single unit.
Amazon’s requirements change: FNSKU specs, poly bag rules, and labeling standards get updated throughout the year. A dedicated prep center already handles staying current as part of the job.
Rejected shipments cost more than prep fees: A shipment rejected for non-compliance faces delayed check-in and stranded inventory. Many cases also add a defect fee on top of the lost time. That single mistake can outweigh months of prep center fees.
What to Ask a Prep Center About Pricing
Is pricing per unit, or does it include hidden fees?
Ask whether receiving, storage, and outbound shipping get billed separately from the prep fee. That lets you compare the true total cost.
Is there a minimum order or setup fee?
Some prep centers require a deposit or a minimum monthly volume before onboarding you. That changes the real cost at low volume.
Does the rate change with complexity?
A flat per-unit rate that ignores kitting, fragile handling, or bundling can mislead you. This matters most once your product mix gets more complex.

FBA Prep Cost Per Unit: Frequently Asked Questions
How much does Amazon FBA prep typically cost per unit?
Most FBA prep services charge $0.50 to $2.00 per unit. The exact rate depends on labeling complexity, poly-bagging needs, and whether the item requires bundling or kitting.
At what volume does a prep center become cheaper than DIY prep?
Most sellers hit that break-even point somewhere around 200 to 500 units per shipment. Below that, DIY prep is often manageable. Above it, a prep center’s time savings and lower error rate usually win out.
Does FBA prep cost more for bundled or kitted products?
Yes. Combining multiple items into one sellable unit takes more labor per kit than labeling a single product. That pushes the per-unit cost toward the higher end of the range.
What happens if I skip prep and Amazon finds compliance issues?
Non-compliant shipments can face rejection, delayed check-in, stranded inventory, or a defect fee. That usually costs more than the original prep would have.
Does Shiprep charge extra fees on top of its per-unit prep rate?
No. Shiprep runs with no advance payment, no setup fee, and no minimum order quantity. The pricing you see reflects what you actually pay to get started.
