Wholesale sellers have three ways to get inventory prepped for FBA: do it yourself, use a prep center, or buy from a supplier that preps and ships straight to Amazon. Since Amazon stopped offering prep and labeling services for US FBA shipments in 2026, this choice matters more than ever.
Quick answer: Supplier prep is usually fastest and simplest when your supplier offers it, because stock goes straight to FBA. A prep center is better when you buy from many suppliers, need inspections or want to combine products. Doing it yourself costs the least cash but the most time.
The Three Options
| Do it yourself | Prep center | Supplier prep | |
|---|---|---|---|
| How it works | Stock ships to you, you prep and send to FBA | Stock ships to a prep center, it preps and sends | Supplier preps and ships straight to FBA |
| Extra shipping leg | Yes | Yes | No |
| Speed | Depends on your time | Adds a few days | Fastest |
| Cost | Your time and supplies | Per-unit prep fees | Depends on the supplier |
| Inspection | You see every unit | The center can inspect | You rely on the supplier |
| Works with many suppliers | Yes | Yes | Only that supplier’s stock |
When a Prep Center Makes Sense
- You buy from many suppliers and want one place to prep everything
- You want units inspected before they go to Amazon
- You bundle products from different suppliers
- Your supplier does not offer labeling or FBA shipping
When Supplier Prep Makes Sense
- Your supplier labels, bags and ships to FBA
- You want stock in Amazon as quickly as possible
- You want to avoid paying to ship stock twice
- You reorder the same products regularly
Do I Need a Prep Center for Amazon Wholesale?
Not always. If your supplier preps and ships to FBA, you may not need one. Many sellers use both: supplier prep for regular reorders, a prep center for mixed or new products.
Whichever you choose, make sure prep is done right; see how to avoid unplanned prep fees and how to choose between LTL vs SPD shipments.
