1. What a Shipping Plan Actually Is

A shipping plan is the document Amazon makes you fill out before they let you send inventory into their warehouses. It tells Amazon what you're sending (which ASINs, how many units of each), how it's packed (single SKU per box, mixed SKU per box, individual labels or sticker-less commingled), and which warehouse Amazon wants you to send it to.

You create it in Seller Central under Inventory > Manage FBA Shipments. The interface looks like it was built in 2014 because it was. The flow is finicky and a single wrong click can mess up your whole batch. This tutorial walks you through the exact sequence.

2. Before You Touch Seller Central

Gather these inputs first. Doing this saves you 40 minutes of going back and forth.

  • The list of ASINs and quantities you're shipping. Match each ASIN to the exact one you bought (look at the parent vs variation listing carefully).
  • The weight and dimensions of each fully packed box. Length, width, height in inches, weight in pounds.
  • The pickup or origin address. If you use a prep center, this is the prep center's address. If you DIY, it's your home or storage unit address.
  • Your printer. You'll print FBA labels (small thermal labels) and shipping labels (full-page UPS or USPS labels).
  • The product condition. Almost always "New" for OA/RA, but specify if it's used.

Some prep centers handle the shipping plan creation entirely for you. Mine does. If yours does, you just supply the inventory list and dimensions, and they create the plan and print labels. Worth confirming with your prep center upfront.

3. Step 1: Send/Replenish Inventory

In Seller Central, go to Inventory > Manage Inventory. Find the ASINs you're shipping. Check the box next to each. From the action dropdown, select "Send/Replenish Inventory." If this is your first time, Amazon will walk you through ship-from address setup. Use the prep center's address or your home address.

"We're going to submit single batches single shipment. Not important here. From here you're going to create your shipping plan. You're just going to click and you'll see that it goes through Amazon." Chris, Free 20 Hours Amazon FBA Course | Complete NO BS A-Z Blueprint

If you're shipping multiple ASINs in one batch, select them all at once. Amazon will combine them into a single shipping plan.

4. Step 2: Pick a Packing Type

Amazon asks: "Are all units in your shipment the same product?" Pick:

  • Case-packed: all units in each box are the same SKU. Used when you bought from a wholesale supplier with retail-ready cases. Most beginners skip this option.
  • Individual products: mixed SKUs per box. This is what almost every OA/RA seller uses.

Pick Individual products unless you have wholesale cases.

5. Step 3: Enter Quantities

For each ASIN, enter the total quantity you're sending. Amazon then tells you whether the products require prep (most don't), whether they require labels (most do for OA/RA sellers), and confirms expiration date for grocery/consumable items.

Two label options:

  • Stickerless / Commingled: Amazon ships any matching unit when a customer orders this ASIN. Doesn't have to be your unit. Used to be popular for branded products. I no longer recommend this because if another seller's units in the commingled pool fail quality, your account gets the IP claim.
  • Manufacturer barcode or Amazon barcode (FNSKU): Each of your units gets a unique label tying it to your seller account. If a quality complaint hits, Amazon can verify it's actually a unit you shipped. This is the safe choice.

Always pick the FNSKU label option. The $0.20 per unit Amazon used to charge for the label is now free for sellers who DIY-label at home or have their prep center label.

6. Step 4: Inbound Placement Service Decision

Amazon then offers you the Inbound Placement Service choice. Two flavors:

  • Free (split shipment): Amazon tells you to send inventory to 2-4 different warehouses. You pay nothing extra to Amazon. You pay more in carrier costs because you're shipping smaller boxes to multiple destinations.
  • Paid (single warehouse): Amazon takes a fee per unit ($0.27 to $0.49 typically) and lets you send the entire shipment to one warehouse. Amazon then redistributes internally.

For small batches under 50 units, paid placement to a single warehouse usually nets out cheaper because of the carrier savings on consolidated boxes. For larger batches (100+ units), the free split option usually wins.

Run the math both ways the first few shipments. Amazon shows you the projected per-unit cost for each option before you commit. Pick whichever is lower. After 3-5 shipments you'll know your usual answer.

7. Step 5: Print FBA Labels

Amazon generates the FBA labels (FNSKUs) for each ASIN. These are the small labels that go on each unit. Print them on thermal labels (Dymo, Rollo, Zebra) using sticker paper. Some prep centers print on 4-up letter paper if they don't have a thermal printer; either works.

Each unit gets ONE FNSKU label, placed over the original UPC. The label should be flat, not creased. It should not be cut off at any edge. If you have a sticker peeling, fix it before the box ships. Amazon scans these labels at intake and a damaged label = lost unit.

8. Step 6: Confirm Shipment and Choose Carrier

Once labels are printed and applied, return to Seller Central and confirm the shipment. Amazon now asks: "Who will be your shipping carrier?"

Three real options:

  1. Amazon Partnered Carrier (UPS or USPS). Amazon negotiates volume rates with UPS/USPS and passes them to you. For small parcel (under 50 lb per box) this is usually the cheapest option.
  2. Amazon Partnered Carrier (LTL/freight). For pallets and larger volumes. LTL pallet shipping tutorial.
  3. Non-Amazon carrier (your own UPS/FedEx account). Use your own carrier account if you have negotiated better rates than Amazon Partnered.

For 95 percent of small-batch OA shipments, use Amazon Partnered UPS. Cheaper than anything you could negotiate as a small seller.

9. Step 7: Enter Box Content

This is the step that trips up the most beginners. Box content tells Amazon what ASINs and quantities are in each box. There are two ways to enter it.

Manual entry: for each box, type the SKU and quantity. Tedious. Error-prone. Don't do this past your first 2-3 shipments.

Box content upload via 2D barcode: generate a 2D scannable barcode for each box. Amazon's warehouse scans the barcode to know what's inside without your typing. Faster, less error-prone, and required for shipments over 50 units.

"So we are going to enter box content. So what is box content? It's basically the dimensions and the SKUs that are in each box. You can enter it manually or you can use the 2D barcode upload, which is much faster." Chris, Free 20 Hours Amazon FBA Course | Complete NO BS A-Z Blueprint

If you skip box content entirely, Amazon charges a $0.15 per unit "manual processing" penalty fee. Don't skip it. This is one of the easiest avoidable fees.

10. Step 8: Enter Box Weights and Dimensions

For each box you're shipping, enter:

  • Weight in pounds (round up to the nearest pound; carriers calculate at the higher number anyway).
  • Length, width, height in inches.

Amazon caps each box at 50 lb. If a box is over 50 lb, you can ship it but must apply a "Heavy Package" label. For LTL freight, the limit changes (up to 100 lb per box on freight pallets).

Use a kitchen or shipping scale that reads in 0.1 lb increments. Estimating by feel is how shipments get rejected at Amazon intake for weight mismatch.

11. Step 9: Print Shipping Labels

Once box content and dimensions are confirmed, Amazon generates UPS or USPS shipping labels. Each label has the destination warehouse address, the tracking number, and the FBA shipment ID.

Print one label per box. Apply to the top of the box. Tape it down on all sides to prevent peeling. The label needs to be scannable at warehouse intake; a torn or wrinkled label causes rejections.

You also need to apply the FBA shipment ID barcode to each box. Most modern Amazon labels combine this into one label. If your batch is generating two labels per box, apply both.

12. Step 10: Hand Off to UPS or USPS

Drop the boxes at a UPS Store, FedEx Office (yes, FedEx Office accepts UPS pickup), or schedule a UPS pickup. USPS goes to your local post office for parcels under 70 lb. Get a receipt with the tracking numbers stapled to it.

Once UPS/USPS scans the boxes, your shipment status in Seller Central changes to "In Transit." Amazon receives the boxes 2-7 days later depending on origin, and processes them within 24-72 hours. Once processed, your inventory shows up as "Available" in Manage Inventory and listings go live.

13. Common Errors and How to Fix Them

Most shipping plan errors fall into these categories.

"Box content not received" warning: Amazon couldn't scan your 2D barcode. They'll charge the manual processing fee. Re-print and re-attach the barcode for next time.

Inventory marked "unfulfillable": Amazon found damaged units, label issues, or expired products. Open a case to investigate. Most fixable but takes 7-14 days.

"Wrong product detected": the unit you shipped doesn't match the ASIN you declared. Amazon will quarantine the unit. Open a case with photos. Common cause: you bought a parent product but the listing was a variation, or vice versa.

Stranded inventory: shipped successfully but listing got suppressed. Common reasons: brand restrictions changed, IP complaint filed against the listing, or you don't have the latest authorization. Check the Stranded Inventory report in Seller Central and act on each one. How to fix stranded inventory fast.

14. What to Do Differently After Your First 5 Shipments

The first 5 shipments are slow and error-prone. By shipment 10 you'll have a rhythm. After that, optimize for:

  1. 2D barcode by default. Saves time and skips the manual processing fee.
  2. Mixed-SKU boxes. Pack ASINs together by size tier instead of by SKU. More units per box = lower per-unit shipping.
  3. Send larger batches less frequently. Each shipment has fixed overhead (labels, carrier dropoff). Larger batches amortize that overhead.
  4. Pre-print labels at the prep center. Have FBA labels and shipping labels ready the same day inventory arrives.
  5. Use partnered freight (LTL) once you're at 200+ units per shipment. Big cost savings vs small parcel at that volume.
