All Things Prep
Supplier to prep centre to FBA

Do not change supplier addresses until the route is mapped

Supplier-direct prep works when each carton has a reference, the prep requirements are known and the first batch proves receiving, exception handling and dispatch before the seller scales the route.

First-batch handover

Best fit for

  • Wholesale sellers sending supplier cartons directly into a prep centre
  • OA sellers routing retailer parcels into ATP instead of home
  • Private-label sellers moving freight-forwarder or launch stock through a controlled prep route

What ATP handles

  • Reference plan for supplier, retailer, courier and freight-forwarder inbound
  • Receiving checks for expected cartons, units, shortages, damage and mismatches
  • Prep and dispatch flow before FBA receives the stock
  • Staged switch plan so sellers avoid redirecting every address at once

Next step

Ask ATP for pricing, fit and next steps before you reroute live stock.

The address is not the strategy

Changing the ship-to address is easy. Making the stock traceable when it arrives is the part that matters.

Supplier shortages need early evidence

Wholesale cartons should be checked against expectation before shortages disappear into normal prep.

OA parcels need traceability

Retailer deliveries should keep tracking numbers, order numbers and expected units visible through receiving.

Workflow

  1. Choose which supplier, retailer or freight-forwarder route will be tested first.
  2. Share references, expected units and prep rules before the stock is dispatched.
  3. ATP receives, checks and flags mismatches before approved stock moves to prep.
  4. Scale the route only when receiving, communication, prep and dispatch are predictable.

Route options

Which inbound route should you test first?

Supplier direct

Best for wholesale cartons where supplier references, carton counts and expected units can be shared before dispatch.

Retailer direct

Best for OA parcels when tracking numbers and retailer order references are kept visible.

Freight forwarder direct

Best for private-label or import stock where cartons need receiving, prep, staging and FBA dispatch planning.

Handover details

The information ATP should have before stock arrives

  • Seller name and ATP contact route
  • Supplier or retailer order number
  • Tracking number or freight reference
  • Expected cartons, parcels and units
  • SKU list and FBA prep requirements
  • Damage, shortage and hold-before-action rules

Should I send all supplier orders to ATP immediately?

Usually no. Test one representative route first, then scale when receiving and prep are predictable.

What if the supplier will not include references?

Use the best available identifiers before dispatch and keep tracking/order details visible so ATP can match the inbound faster.

Can this work for OA parcels?

Yes, but OA needs parcel-level tracking and split-delivery logic rather than supplier-carton receiving only.
