Amazon for suppliers — Vendor Central & Direct Import

How to sell to Amazon as a vendor — and get the second PO

Updated

Vendor Central is invite-only, runs on purchase orders and EDI, and deducts money for every mistake. Direct Import lets Amazon buy straight from your factory. Here's how both work, why vendors lose margin, and everything our team manages on Amazon every day.

The short answer

To sell to Amazon as a vendor: get the Vendor Central invitation (or make the case for one); negotiate terms you can live with; set up every item with complete content and A+ pages; acknowledge every PO on time, ship to Amazon's routing and labeling rules, and send the ASN before the truck arrives; keep your fill rate and lead times inside Amazon's targets; reconcile every remittance for chargebacks, shortage claims and allowance deductions and dispute the wrong ones; and, if you manufacture overseas, use Direct Import so Amazon buys at the factory. Or hand all of it to a team that does it every day.

A factory that had never sold to Amazon

One factory we worked with had never done business with Amazon. We got Amazon to fly out and visit the factory. Amazon's first purchase order was $1.2 million. The next year, Amazon ordered $8 million through its Direct Import program. That's what a vendor relationship looks like when the setup, the content and the compliance are handled right from the first PO.

If you already sell to Amazon as a vendor, you know the list

The invitation. The vendor terms — payment terms, freight allowance, damage allowance, co-op, the AVS conversation. Vendor Central. EDI over AS2 — 850, 855, 856, 810, 846 — with the ASN due hours before the shipment arrives and SSCC labels that must match it exactly. The routing guide, carrier appointments, carton and pallet prep. Chargebacks in six flavors: PO, ASN, prep, packaging, transportation, receive. Shortage claims and price claims on the remittance. Fill-rate and on-time targets that move every year. A+ content, Brand Store, Vine. And on Direct Import: booking windows, ship-window-open dates, import documents due days after departure, and chargebacks for missing any of them.

Every one of those is a place to lose margin or lose the next PO. Our team runs all of them for home furnishing suppliers, inside your Vendor Central account. You keep the account and the relationship; we do the work.

How selling to Amazon as a vendor actually works

Vendor Central is Amazon's first-party (1P) wholesale channel. You're invited. Amazon buys your products at a negotiated cost, owns the inventory, sets the retail price, sells and ships it. You receive purchase orders, ship to Amazon's fulfillment centers to Amazon's rules, invoice, and get paid on terms — minus whatever Amazon deducts. Almost everything runs on EDI. Direct Import is Vendor Central for overseas manufacturers: Amazon buys at your factory (FOB), books the freight and imports the goods itself, so the factory sells direct without a US importer in the middle. It has its own booking windows, document deadlines and chargebacks.

Three things decide whether the POs keep coming: whether you ship complete and on time every time, whether your listings convert once Amazon has your product, and whether you catch and dispute the deductions before they eat the margin.

Everything we manage for you on Amazon

Getting in and staying in

  • Positioning your line for a Vendor Central invitation — category fit, catalog readiness, the pitch to Amazon's vendor managers; Direct Import qualification for overseas factories
  • Vendor terms reviewed line by line — payment terms, freight and damage allowances, co-op, returns, AVS — so you know what you're agreeing to before the first PO
  • Vendor Central account and user administration; Vendor Central cases opened, chased and closed
  • EDI onboarding and testing (AS2 or SFTP): 850 purchase orders, 855 acknowledgments, 856 ship notices, 810 invoices, 846 inventory; web forms where volume doesn't justify integration

Catalog and content

  • Item setup to Amazon's spec: GTINs/UPCs, required attributes, dimensions and weights, variations (parent/child), hazmat and compliance documentation
  • Titles with the words shoppers search, bullets, descriptions, backend keywords; images to Amazon's spec (main on pure white, angles, lifestyle, infographics); product video
  • A+ content built for every item that earns it; Brand Store kept current; Vine enrollment coordinated for new items
  • New item introductions and discontinuations handled cleanly — a removed item's ASIN never disappears, so it has to be managed, not abandoned

Purchase orders, shipping and inventory

  • Every PO acknowledged inside Amazon's window with accurate quantities and dates — the 855 is where fill-rate problems start
  • Shipments prepared to Amazon's routing guide: carrier appointments, carton and pallet labeling (SSCC-18), prep rules; ASN (856) transmitted before arrival and matching the shipment exactly
  • Fill rate, on-time delivery and lead-time performance monitored daily against Amazon's current targets; backorders and cancellations handled before they become metrics
  • Inventory and availability kept accurate so Amazon's forecasting keeps ordering
  • Direct Import: shipment bookings inside the window (before Ship Window Open), import documents submitted on time after departure, cargo delivery inside the PO window, no-show avoidance — every one of these has its own chargeback

Getting paid

  • Every remittance reconciled — invoices matched, chargebacks by category (PO, ASN, prep, packaging, transportation, receive), shortage claims, price claims, allowance deductions
  • Shortage and price claims disputed with proof of delivery and the PO record; wrong chargebacks disputed inside Amazon's window; short and late payments chased

Returns and claims

  • Vendor returns, damage and defect claims handled to Amazon's rules; return rate and defect rate watched by item

Growing sales on Amazon

  • Vendor Central analytics read weekly — what's selling, what's forecast, what's out of stock
  • Amazon Advertising (Sponsored Products / Brands) coordinated with your ad partner; deals and promotions coordinated with your vendor manager
  • Buyer relationships, line reviews and new-item pitches — 20+ years selling home furnishings into the majors
  • One login on our platform to see what sold, what's live, and what we fixed

Why vendors lose money on Amazon

  1. 1

    Chargebacks go unchallenged. Six categories, all automated, each with a dispute window. Nobody reconciles the remittance, so they stand.

  2. 2

    Shortage claims eat the invoice. Amazon says fewer units arrived than you shipped; without the ASN and proof of delivery in order, you can't win it.

  3. 3

    Late 855s and missing 856s. The acknowledgment and the ship notice are where most compliance failures start.

  4. 4

    Thin listings don't convert. Amazon owns the price, but the content is yours — and incomplete listings sit.

  5. 5

    Fill-rate misses stop the POs. Amazon forecasts from your performance; miss the targets and the orders shrink.

  6. 6

    Direct Import deadlines. Booking windows and document deadlines are strict, and every miss is a chargeback.

Proof

  • $1.2M → $8M — one factory's first two years selling direct to Amazon through Vendor Central and Direct Import
  • $10M → $32.5M in one year — one client's online sales
  • $100M+ in online sales managed and helped produce across Amazon, Home Depot, Wayfair and the other majors — 20+ years

Frequently asked questions

How do I become an Amazon vendor?

Vendor Central is invitation-only; Amazon's vendor managers invite brands based on category fit, catalog and sales history. The invitation arrives at your business email. We position lines for invitation and handle the setup once it comes.

What is the difference between Amazon Vendor Central and selling on Amazon yourself?

As a vendor, Amazon buys your product wholesale, owns the inventory, sets the price and handles the customer. You manage purchase orders, shipments, content and deductions. It's a wholesale relationship, and it's the one we manage.

What is Amazon Direct Import?

A Vendor Central program for overseas manufacturers where Amazon buys at your factory (FOB), books the freight and imports the goods itself — so a factory sells direct to Amazon without a US importer or distributor. It carries its own booking and document deadlines.

What are Amazon vendor chargebacks?

Automated deductions for not following Amazon's rules on purchase orders, ship notices, prep, packaging, transportation and receiving. Each has a dispute process and a window; the ones you don't dispute, you pay.

What is A+ content?

Enhanced product-page content — image modules, comparison charts, brand story — that Amazon lets vendors add below the standard listing. It lifts conversion and we build it for every item that earns it.

Can Grow ECommerce run Vendor Central for us if we already sell there?

Yes. We audit the catalog and the last year of remittances, fix and complete the listings, take over PO and shipment compliance, and dispute what's been wrongly deducted.
