A prep centre takes care of FBA prep for your stock: receiving, quality control, FNSKU labelling, packaging and shipping to Amazon's fulfilment centres. Since Amazon ended commingled inventory at the end of March 2026, resellers must label every single unit. For many sellers in online arbitrage and wholesale, an FBA prep centre is therefore more important than ever. In this guide you will learn what a prep centre does, what it costs, how arbitrage sellers scale with it, how to find the right provider and which prep centres in the UK and Europe we support in ProfitDesk.
What is an FBA prep centre?
An FBA prep centre is a logistics provider that prepares your products for Amazon FBA. It is also called pre-FBA or Amazon prep. Instead of suppliers shipping stock to your home, it goes straight to the prep centre. There it is checked, prepared to Amazon's requirements and standards, and sent on to Amazon's warehouses.
For sellers this has two big advantages: time saved, because packing and labelling are outsourced, and scalability, because you can grow without your own warehouse space or staff. You put the time you gain into sourcing and growth.
Why FBA prep matters more in 2026
Since 31 March 2026 Amazon no longer accepts commingled inventory. Every unit resellers send to Amazon must carry its own FNSKU label. Only brand owners with Brand Registry may keep using the manufacturer barcode. If you sell many different products, you now apply far more labels than before. That is exactly the work a prep centre takes over. More in our guide to the FNSKU.
On top of that, badly prepared shipments can lead to extra fees, check-in delays or rejections at Amazon. A professional prep centre lowers that risk because it applies Amazon's labelling and packaging rules every day.
How FBA prep works: the route to Amazon's fulfilment centres
- Purchase: you order from your supplier and use the prep centre as the delivery address.
- Check-in: the prep centre receives the shipment, records every delivery and checks it for damage and discrepancies.
- Prep: apply FNSKU barcodes, poly bags or bubble wrap, build bundles and multipacks.
- Packing: stock goes into shipping boxes or onto pallets to Amazon's shipping requirements.
- Shipping: shipments go to Amazon's warehouses, usually via Amazon's partnered carriers.
- Selling: once Amazon has checked the shipment in, the stock is ready to sell.
Many prep centres usually process stock within 24 to 48 hours of check-in. Most steps can be managed digitally, so you see the status of your deliveries online and keep all the data in view.
What services does a prep centre offer?
Services vary by provider. Most offer these building blocks:
- Receiving and quality control: check-in, counting, checking for damage and whether the item matches the Amazon listing
- FNSKU labelling: printing and applying labels, covering old barcodes
- Packaging: poly bags, bubble wrap, sealing, warning labels to Amazon's rules
- Bundles and multipacks: combining several units into one sellable item
- Palletising: packing and labelling shipments, pallets for larger volumes
- Storage: holding stock until the shipment goes to Amazon
- Returns: many prep centres now also receive returns, inspect them and prepare them for resale
- FBM fulfilment: some providers also ship directly to customers
Hazmat products and special requirements
Not every service suits every product. Hazmat products such as batteries, sprays or certain liquids must be prepared especially safely, and not every prep centre may accept them. The same applies to oversize items or food with best-before dates. Clarify such needs before your first enquiry so the provider meets the right standards.
How arbitrage sellers scale with prep centres
For many arbitrage sellers, a prep centre is the biggest lever for growth. As soon as not every parcel passes through your own hands, your sales no longer depend on your own time.
- Scaling without your own hands: many sellers order stock from online shops straight to the prep centre. They only handle sourcing and analysis, the prep centre handles the logistics.
- A shared prep warehouse: some arbitrage sellers set up their own small prep warehouse together and share the cost of space and staff.
- Working from anywhere: because stock never has to arrive at your home, many sellers run their business on the move. They travel the world and have their stock prepped at the prep centre.
- Outsourcing returns: returns can now be handled through many prep centres instead of landing at your door.
That is how you take your Amazon business to the next level without packing boxes yourself.
How much does FBA prep cost?
Most prep centres charge per unit, plus fees for boxes, poly bags, bundles and storage. As a rough guide, prices in Europe often range from about €0.30 per unit for simple wholesale stock to €1.50 for online arbitrage stock that needs more work. UK prep centres price in pounds, so always ask for a quote. Costs depend on volume and complexity, and usually fall as volumes rise. Some providers offer free storage for a limited time when you start. Terms change regularly, so always ask for current prices.
Include prep costs in every calculation. Our guide to Amazon FBA costs shows how they affect your profit.
Prep yourself or outsource?
- A prep centre pays off if you sell many different products or larger volumes, have no time or space for packing, order stock from many online shops as in online arbitrage, or want to scale your Amazon FBA business without your own warehouse and staff or work from anywhere.
- Prepping yourself pays off if you are just starting and sell only a few units, have time and want to keep costs low, or want to check every unit yourself.

How to find the right provider
- Location: close to your suppliers and Amazon's warehouses saves time and shipping costs.
- Services: does the prep centre offer everything you need, such as bundles, returns or hazmat?
- Transparent pricing: clear fees per unit, box and storage, nothing hidden. Many providers publish their price list on their website.
- Turnaround time: how fast is your stock at Amazon after check-in?
- Software and integration: can you see the status of every delivery live? Does it connect to your tools?
- Liability and insurance: what happens with damage or loss in the warehouse?
- Test shipment: start with a small shipment before sending larger volumes.
