How shipping works: what a prep center does for you

What is a prep center?

A prep center is a warehouse that gets products ready for a marketplace. Sellers use the name because the work is called "prep": checking each item, sticking on the right label, bagging or boxing it to the marketplace's rules, and shipping it to the marketplace's own warehouse. On Amazon, this is the step between the store you bought from and Amazon's fulfillment warehouse.

People who resell by hand either do this at their kitchen table or pay a prep center to do it. Take Profit uses a partner prep center for every item, and talks to it for you. You buy, the warehouse does the rest, and the app shows you where your item is.

Why does the item go to a warehouse and not to me?

Because marketplaces have rules. Each item needs a specific barcode label. Some need to be bagged, some boxed, some sealed. The shipment to the marketplace needs its own labels and a box that meets size and weight limits. Get any of it wrong and the marketplace rejects the shipment or charges you to fix it.

Learning those rules, buying the supplies, printing labels, and driving to the post office is most of the work in reselling. Sending the item straight to a warehouse that already does this all day removes it.

What happens to your item, step by step

1. Step 1

   You buy, and ship to the warehouse

   At the store's checkout you enter the warehouse address the app gives you instead of your own. Nothing else about buying changes.

2. Step 2

   The warehouse receives it

   When the store's delivery arrives, the warehouse logs it against your order. The app updates the item's status so you know it landed.

3. Step 3

   It gets checked

   Staff open the delivery and check the item is the right product, the right quantity, and undamaged. Problems are flagged in the app.

4. Step 4

   It gets labeled and packed

   The item gets the marketplace's barcode label and any bagging or boxing the rules require. Then it goes into a shipment with the right shipping labels.

5. Step 5

   It ships to the marketplace

   The shipment goes to the marketplace's own warehouse. The app tracks it on the way.

6. Step 6

   Your listing goes live

   Once the marketplace checks the shipment in, your item is for sale under your seller account. From here the marketplace ships to the buyer and handles returns.

How long does shipping take?

From the day you buy to the day your item is live for sale, plan on about three weeks. That includes the store's delivery to the warehouse, a few days of checking and packing, shipping to the marketplace, and the marketplace checking the shipment in. It can be faster or slower depending on the time of year. The weeks before big holidays are the slowest, because every warehouse in the chain is busy.

What does the warehouse cost?

A per-item fee for checking, labeling, and packing, charged when your item is prepped. You do not pay it before the item arrives. The profit number on every item in the app already subtracts this fee, along with the marketplace's fees and shipping, so the profit you see is the profit you keep.

What if an item arrives damaged or wrong?

The warehouse flags it in the app instead of sending it on. Because you bought the item from the store, the refund or replacement comes from the store, the same as with any online order. In most cases that means opening a return or claim on the store's website. If the problem happens later, after the item reached the marketplace, you deal with the marketplace's support.

Three habits keep this rare:

• Buy from the exact link the app gives you, so the product matches the listing.
• Buy the quantity you meant to. The warehouse checks the count against your order.
• Check the app's status for each item every few days so a flag does not sit unread.
