Sending Inventory Into FBA Without Shipment Errors

Every FBA shipment is a promise. You declare SKUs, quantities, cartons and labels, and the fulfilment centre checks your physical goods against that declaration. When the two match, stock goes sellable within days. When they do not, you wait, and your listing waits with you. This is the inbound workflow we run so they always match.

Check-in problems cost weeks, not units

A discrepancy rarely loses your stock. It loses your time. A shipment flagged for investigation sits while the platform counts, recounts and decides, and through all of it your listing can show out of stock during the exact period you shipped inventory to prevent. Sales rank slips. Ads either pause or burn on an unbuyable page. The unit you shipped is worth less by the time it goes live. So we treat inbound accuracy as a revenue task, not a warehouse chore, and we run it as a fixed checklist every single time.

Prep the product before the shipment exists

Prep failures are decided before you ever open the shipment workflow. The fulfilment centre will not quietly fix your packaging. It will flag it, charge for correction where the programme allows, or refuse the goods. So prep happens at your warehouse, against a written standard maintained per SKU.

• Polybag anything that can leak, spill or scuff. Bags above the size threshold carry a suffocation warning, and every bag is sealed.
• Bubble wrap fragile units so a single unit survives a drop onto a hard floor.
• Sets and combos travel as one unit. Tape or bag them together with a note that they must not be separated.
• Expiry-dated products carry the date in the required format and meet the minimum remaining shelf life the category demands.
• Remove or cover every old barcode. A scanner that finds two codes will pick one, and it may not be yours.

One unit, one scannable barcode

Labelling errors cause most of the check-in mismatches we see. The rule is simple. Each sellable unit carries exactly one scannable barcode that resolves to your listing. That is either the manufacturer barcode, where the platform permits it, or the FNSKU label generated for your SKU. We default to FNSKU labels on everything. It removes ambiguity at the dock and means the scan always maps to your offer and your stock, nobody else’s.

Print labels from the current shipment workflow itself, never from an old file. FNSKUs can differ across conditions and marketplaces, and a stale label file is how five hundred units ship under the wrong code. Before sealing cartons, scan-test one labelled unit per SKU with any barcode app and confirm the code matches the shipment plan. It takes two minutes and it catches the most expensive mistake in this entire process.

Carton rules the dock actually enforces

The receiving dock cares about three things: can the carton be lifted safely, can it be scanned instantly, and does its content match the manifest. Everything in your carton standard should serve those three.

• Stay within the carton weight limit. Check the current limit inside the shipment workflow for your category and pack below it. Overweight cartons get flagged at the dock.
• One carton label per carton, on a flat side. Not on a seam, not over the tape, never wrapped around a corner.
• Do not mix SKUs in a carton unless the contents are declared that way. Undeclared mixed cartons are the fastest route to a miscount.
• Match the box-level declaration exactly. If the plan says 24 units in carton three, pack 24. Not 23, not 25.
• Use rigid, fresh cartons. A crushed carton invites a manual recount, and manual recounts create delays.

The discrepancies you will actually see

Almost every check-in problem falls into four buckets, and each bucket has a prevention step you control.

• Units received short. Usually a packing miscount or an undeclared mixed carton. Prevention: a two-person count at sealing, logged carton-wise.
• Units received in excess. Sounds harmless. It still triggers investigation and holds the shipment. Same prevention.
• Unscannable or mismatched labels. Prevention: fresh label prints per shipment plus the one-unit scan test.
• Wrong carton count. The manifest says ten boxes and the dock scans nine. Prevention: photograph all sealed, labelled cartons together before handover and keep the courier’s pickup acknowledgment.

When a discrepancy lands anyway, work it inside the reconciliation window with evidence, not opinion. Packing photos, carton weights from the courier docket, invoice copies, the pickup acknowledgment. Claims filed with documents get resolved. Claims filed with frustration get closed.

The pre-dispatch checklist

We run this list on every shipment regardless of size, because the small shipments are where discipline quietly dies.

• Prep standard confirmed per SKU, all old barcodes covered.
• Labels printed fresh from this shipment, one unit scan-tested per SKU.
• Carton counts verified by two people and logged carton-wise.
• Carton labels on flat sides, weights within the current limit.
• Photos of sealed cartons and the courier docket filed against the shipment ID.

It is boring and repeatable, and that is exactly why the shipments check in clean. This discipline is a standard part of Amazon India Account Management as we run it, because inbound is not a logistics detail. It is the start of every sale you will make this quarter.
