Quick Start

1. Choose Your Marketplace

• US (Amazon.com): Largest market, highest competition
• UK (Amazon.co.uk): English-speaking, VAT required
• EU (Amazon.de, .fr, .it, .es): Multi-country expansion
• JP (Amazon.co.jp): Unique requirements, local language needed

2. Determine Product Category

See references/category-requirements.md for: - Category-specific requirements - Approval needed categories (gated) - Restricted products list - Compliance documents needed

3. Check GTIN Requirements

• Need UPC? Most categories require valid UPC/EAN
• GTIN Exemption? See references/gtin-exemption-guide.md
• Brand Registry? Required for some exemptions

4. Prepare Product Information

Use templates: - templates/product-template.txt - Fill in your product details - templates/image-checklist.txt - Ensure images meet requirements

5. Create Listing

See references/listing-workflow.md for step-by-step instructions.

Core Workflows

New Product Listing

1. Category Selection - Check if gated/approval needed
2. Product Information - Title, bullets, description, keywords
3. Images - 7 images minimum, pure white background for main
4. Pricing & Inventory - Cost analysis, competitive pricing
5. Fulfillment - FBA vs FBM decision
6. Submit & Monitor - Wait for Amazon review

GTIN Exemption Application

1. Verify eligibility - Private label, generic, or custom products
2. Prepare proof - Trademark, website, or product packaging
3. Apply in Seller Central - Inventory > Add Products > GTIN Exemption
4. Wait for approval - Usually 24-48 hours
5. Create listing - Use exemption to list without UPC

See detailed guide: references/gtin-exemption-guide.md

FBA Shipment Creation

1. Create shipping plan - Inventory > Manage FBA Inventory
2. Set quantity - Accurate count needed
3. Prep products - Labeling, packaging requirements
4. Print labels - FNSKU product labels, box labels
5. Ship to Amazon - Use partnered carrier or your own
6. Track receipt - Monitor inbound status
