Getting your inventory into Amazon’s fulfillment network correctly is one of the most overlooked parts of running a wholesale business — and one of the easiest places to lose money through labeling errors, prep mistakes, or shipping delays. A well-built FBA shipment plan keeps your inventory moving smoothly from supplier to shelf-ready at Amazon.
This guide walks through exactly how to create a shipment plan in Seller Central, step by step.
What Is an FBA Shipment Plan?
An FBA shipment plan is the process in Seller Central where you tell Amazon what inventory you’re sending, how it’s packed, and where it’s coming from. Amazon uses this information to generate shipping labels, assign fulfillment centers, and track your inventory once it arrives.
Getting this right matters because errors here — wrong labels, wrong box weights, missing prep — can lead to receiving delays, extra fees, or even inventory being returned to sender.
Step 1: Confirm Your Inventory Is Ready
Before creating a shipment plan, make sure your products are:
- Verified against the correct ASIN (matching condition, variation, and packaging)
- Counted accurately for quantity
- Free from any damage or packaging issues
Any mismatch between what you list in Seller Central and what physically ships can cause receiving discrepancies at the fulfillment center.
Step 2: Start a New Shipment in Seller Central
In Seller Central, go to Inventory → Manage FBA Inventory, select the products you’re shipping, and choose Send/Replenish Inventory. From here you’ll:
- Select the products and quantities for this shipment
- Choose whether you’re shipping as an individual product or a case-packed shipment
- Confirm the “ship from” address (your prep center or supplier’s location if shipping directly)
Step 3: Choose Packing Type
Amazon will ask whether your shipment is:
- Individual products — mixed SKUs in each box
- Case-packed products — identical items packed in manufacturer cases with consistent quantities per box
Case-packed shipments are often faster to process since Amazon doesn’t need to verify contents box by box, but they require your supplier or prep center to pack consistently and accurately.
Step 4: Label Your Inventory
Every unit typically needs an Amazon barcode label (FNSKU) unless the product qualifies for Amazon’s barcode (using the manufacturer barcode). This is one of the most common places for errors:
- Labels must be scannable and not placed over existing barcodes
- Each unit needs its own label, not just the outer box
- Labels should be printed at the correct size — smudged or low-resolution labels get rejected
If you’re shipping from Bangladesh, this labeling step is typically handled by a US-based prep center, since Amazon requires labels to be applied before the shipment reaches its fulfillment center.
Step 5: Confirm Box Contents and Weights
For each box in your shipment, you’ll need to declare:
- Which products and quantities are inside
- The box’s weight and dimensions
Accuracy here matters — Amazon may charge additional fees or flag discrepancies if the actual box weight doesn’t match what was declared.
Step 6: Choose Your Shipping Method and Carrier
Amazon will let you choose between:
- Amazon Partnered Carrier (often discounted rates through UPS or others)
- Your own carrier arrangement
For most sellers working through a prep center, the prep center typically handles carrier selection and printing of Amazon’s shipping labels for the outer boxes.
Step 7: Print and Apply Shipping Labels
Once your shipment plan is confirmed, Amazon generates box-level shipping labels showing which fulfillment center(s) your inventory is headed to — sometimes a shipment is automatically split across multiple centers. Apply these labels clearly to each box before pickup.
Step 8: Ship and Track
After your carrier picks up the shipment, track its status in Seller Central under Manage FBA Shipments. Statuses move through:
- Shipped
- In Transit
- Delivered
- Receiving (Amazon is checking in your inventory)
- Closed (inventory is now sellable)
If a shipment shows “receiving” for an unusually long time, or a discrepancy appears between what you sent and what Amazon received, you can open a case with Seller Support to investigate.
Common Mistakes to Avoid
- Skipping FNSKU labeling — leads to rejected or delayed shipments
- Inaccurate box weights — triggers unexpected fees
- Mixing SKUs without declaring them properly — causes receiving errors
- Not tracking shipment status — missed discrepancies can mean lost inventory reimbursement windows
Frequently Asked Questions
Do I need a prep center if I’m shipping from Bangladesh? Yes, in almost all cases. A US-based prep center receives your supplier’s shipment, applies FBA labeling, and forwards it correctly to Amazon’s fulfillment centers.
What is an FNSKU and why does it matter? FNSKU is Amazon’s unique barcode for tracking inventory within its fulfillment network. Without it (or without qualifying for Amazon barcode), your shipment can be rejected at check-in.
Can Amazon split my shipment across multiple fulfillment centers? Yes, this is common and expected — Amazon distributes inventory based on demand forecasting and warehouse capacity, and your shipment plan will show exactly which boxes go where.
What happens if my box weight doesn’t match what I declared? Amazon may apply additional weight handling fees, and repeated inaccuracies can affect your account’s shipment performance standing.
