Amazon Selling Basics

๐Ÿ“ฆ

FBA โ€” Fulfillment by Amazon

You ship products to Amazon's warehouse. When a customer buys, Amazon picks, packs, ships, and handles returns. You pay storage + fulfillment fees but get Prime eligibility. This is the model behind the Wholesale scanner.

๐Ÿšš

FBM โ€” Fulfillment by Merchant

You store and ship products yourself. Lower fees, more work, no Prime badge. Less competitive for the Buy Box.

๐Ÿ†

The Buy Box

The "Add to Cart" button on a listing. ~82% of all Amazon sales go through it. When multiple sellers offer the same product, Amazon picks one winner. FBA + competitive price = best odds.

All profit calculations use Buy Box price.

๐Ÿ“Š

BSR โ€” Best Sellers Rank

Lower = better. BSR #1 is the top seller in its category. BSR #5,000 sells daily. BSR #100,000+ sells occasionally. Updates hourly based on recent sales velocity.

๐Ÿท๏ธ

MAP โ€” Minimum Advertised Price

A brand-set price floor. List below MAP and they can revoke your wholesale account. Products with MAP tend to have stable, protected margins โ€” a good sign for wholesale.

๐Ÿ”’

Gated Brands & Categories

Apple, Nike, Disney and similar require Amazon's approval to sell. You need invoices from authorized distributors to get ungated. Dashboard flags these with a red โš  badge.

๐Ÿ“‹

ASIN

Amazon Standard Identification Number โ€” a 10-character product fingerprint (starts with "B0"). All scanner results are keyed by ASIN. Example: B08KTWXCZT

๐Ÿ”„

Subscribe & Save

Auto-delivery program giving customers 5โ€“15% off recurring orders. High SNS adoption = predictable, stable demand โ€” ideal for wholesale replenishment.

๐Ÿ—‚๏ธ

How Each Page Works

โš ๏ธ Current data is a sample. Each scan pulls 50 ASINs per category and enriches up to 200 products. As the database accumulates over days, results grow deeper. Skip logic kicks in after day 1 โ€” only new or stale ASINs cost tokens. See Future Roadmap for how this scales.

๐Ÿญ

Wholesale Scanner Wholesale tab

Finding: Branded products with strong demand, low Amazon competition, healthy margins โ€” for buying wholesale from distributors and reselling via FBA.

Phase 1 /query/ โ€” Top-selling ASINs per category (~10 tokens/cat) Phase 2 Filter โ€” 2โ€“8 FBA sellers, Buy Box $20+, Amazon out of stock 90%+ Phase 3 /product/ โ€” Enrich: prices, BSR, fees, ratings, monthly sold Phase 4 Score โ€” BSR 40% + Sellers 25% + Margin 20% + Volume 15% Phase 5 DB UPSERT โ€” product_deals table, repeat_count increments Phase 6 JSON โ€” Rebuild from 7-day DB pool, sort by opportunity score

Skip logic: ASINs enriched within 48h are skipped. Token cost drops ~80% after day 1.

๐Ÿ” Seen Nx badge: Product keeps appearing across multiple scans = consistently passes all filters = most reliable wholesale targets.

๐Ÿท๏ธ

Warehouse Scanner Warehouse tab

Finding: Amazon Resale listings at 20%+ discount โ€” for personal buying or Facebook Marketplace flipping. Not for FBA resale.

Phase 1 /query/ โ€” Pull Warehouse ASINs per category Phase 2 /seller/ โ€” Fetch Amazon Resale storefront (1 token, all listings) Phase 3 Intersect โ€” ASINs in both category results AND storefront Phase 4 Skip logic โ€” Compare timestamps โ†’ skip if listing unchanged Phase 5 /product/ โ€” Enrich only new/updated listings Phase 6 Accumulate โ€” 14-day DB window, hourly refresh

Business model: Buy discounted items, resell on Facebook Marketplace at ~70% of retail. Est. flip profit shown per deal.

Below Avg badge: Currently below its 30-day warehouse price average โ€” buy now before it sells.

๐Ÿช

Generics Scanner Generics tab

Finding: Products with no brand protection โ€” unbranded items or listings with so many sellers anyone can jump in. Source from Alibaba.

Query: 5+ FBA sellers, price $8โ€“$50, strong BSR Classification: Generic โ†’ brand = "unbranded","OEM","n/a" or โ‰ค2 chars Open Market โ†’ fbaCount โ‰ฅ 10 (no brand controls it) Accessible โ†’ fbaCount โ‰ฅ 3 (open but not saturated) SKIP โ†’ fbaCount < 3 (brand-controlled)

Business model: Find same product on Alibaba, order with MOQ, list on existing Amazon listing. High competition, lower barrier than wholesale.

Sourcing estimate: 20% of Buy Box price โ€” rough Alibaba equivalent. Actual cost varies heavily by MOQ and supplier.

๐Ÿ—๏ธ

Private Label Scanner Private Label tab

Finding: Categories with strong demand but weak current listings โ€” low reviews, mediocre ratings. Launch a better product under your own brand.

Query: Strong BSR, price $15โ€“$80 Weakness signals: Low reviews โ†’ reviewCount < 200 (easier to beat) Low rating โ†’ rating < 4.0 (unhappy customers = room to win) Both signals โ†’ highest opportunity score boost Viability: not gated, not Amazon-sold, not brand-dominant

Business model: Source from Alibaba with custom branding, create your own Amazon listing, build reviews. Highest upside, highest effort.

vs Generics: Private Label = you own the listing and brand (long-term equity). Generics = piggyback on existing listing (short-term cash flow).

Metrics & Scoring

๐Ÿ†

Opportunity Score (0โ€“100)

BSR Score (40%) โ€” Lower BSR = more sales. BSR #1=100pts, BSR #50K=0pts Seller Score (25%) โ€” 2โ€“5 FBA sellers=100pts. 6โ€“8=60pts. 9+=30pts Margin Score (20%) โ€” Higher est. margin = higher. 33%+ margin=100pts Volume Score (15%) โ€” Monthly units sold. 500+/mo=100pts. Linear. Score 70+ = Strong opportunity (green) Score 45โ€“69 = Worth investigating (amber) Score <45 = Proceed with caution (red)

45% wholesale cost is conservative. Real wholesale: 40โ€“55% of retail. Green = 15%+, Amber = 8โ€“14%, Red = <8%.

๐Ÿ‘ฅ

FBA Seller Count

How many FBA sellers compete on the listing. Sweet spot: 2โ€“5. Too few = restricted or no demand. Too many (10+) = price war. 2โ€“5 = healthy competition, you can win Buy Box.

๐Ÿ“ฆ

Monthly Sold

Amazon's estimate of units sold per month. 100+/mo = solid. 500+/mo = excellent. Weighted 15% in the opportunity score.

๐Ÿ”

Repeat Count (๐Ÿ” Seen Nx)

How many scans a product has survived all filters. The most underrated signal. Seen 5x+ = stable BSR, consistent seller count, reliable margins across multiple data points. These are your safest wholesale bets.

๐Ÿ“‰

Price Stability %

How consistent the Buy Box price has been over 90 days. 80%+ = stable and predictable. Under 50% = volatile โ€” understand why before ordering inventory.

โšก

Warehouse Deal Score

Discount (35%) โ€” Deeper = higher Flip (30%) โ€” Better flip margin = higher BSR (20%) โ€” Popular items sell faster locally Rating (15%) โ€” 4+ stars = easier FB Marketplace sale

Reading Price History Charts

๐Ÿ“ˆ

What Each Line Means

Click ๐Ÿ“Š on any product card to see 90-day price history.

Orange = Amazon's own price (only when they're selling)
Blue = Lowest new third-party price
Pink = Buy Box price (what customers pay)
Green = BSR โ€” lower on chart = selling better
Purple area = Number of new offers

โœ…

Good Chart Pattern

Stable lines for months. BSR consistently low. Orange Amazon line frequently absent (Amazon out of stock = opportunity). 3โ€“5 sellers always present. This is a reliable, replenishable wholesale product.

โš ๏ธ

Warning Patterns

Price dropping steadily. BSR spiking up (fewer sales). Amazon just came back in stock. Seller count jumped from 3 to 15 suddenly. Investigate before ordering.

๐Ÿ’ก

The Amazon Gap

Most valuable thing to look for: long stretches where the orange line is absent. Amazon out of stock = third-party sellers own the Buy Box. If this keeps repeating, Amazon can't maintain inventory โ€” that's your sustainable window.

๐Ÿค

Finding & Working with Suppliers

๐Ÿ“ž

Direct from Brand

Best margins, best relationship. Find "Wholesale" or "Become a Retailer" on the brand's website. Need a resale certificate (free in most states) and business license. Takes time but delivers the best economics.

๐Ÿญ

Authorized Distributors

Buy from brands in massive bulk, resell to smaller retailers. Slightly lower margins but easier approval. Examples: S&S Worldwide, Essendant, McLean Wholesale, PrimeEdge Distribution.

๐Ÿ›’

Faire.com

B2B marketplace with net-60 payment terms (buy now, pay in 60 days). Great for beginners โ€” low MOQs, brands actively want retailers. Dashboard links to Faire for easy-access brands.

๐Ÿ“‹

MOQ โ€” Minimum Order Quantity

Smallest order a supplier accepts. Could be 1 case (12 units) or 1 pallet (hundreds). Always ask before committing capital. Negotiate a trial order on first contact.

๐Ÿ“ง

Outreach Pipeline

โ— New โ€” Identified
โ— Contacted โ€” Waiting
โ— Approved โ€” Account open
โ— Rejected โ€” Try again later

๐Ÿšข

Alibaba (Generics & PL only)

For generic and private label sourcing. Request samples before ordering. Verify supplier reviews and Trade Assurance. Typical MOQ: 100โ€“500 units. Use sea freight for large orders.

How Amazon Resale Works

When customers return items, Amazon inspects and relists them as discounted "Amazon Warehouse" deals.

Amazon Resale (Used offers): Opened but perfect. Best for resale.
Used โ€” Very Good: Minor cosmetic issue only.
Used โ€” Good: Shows wear but fully functional.
Used โ€” Acceptable: Cosmetic damage, works.

We focus on Amazon Resale at 20%+ discount, 4+ stars, $30+ retail value.

๐Ÿ“Œ

Below Avg Price

Current warehouse price is below the 30-day average for that item on Amazon Resale. Priced unusually cheap right now โ€” buy before it sells or gets repriced up.

๐Ÿ•

Updated X Ago

How recently this deal was confirmed live on Amazon Resale. "1h ago" = confirmed this hour. "2d ago" = confirmed 2 days ago, may have sold โ€” check before buying.

API Tokens & How They're Used

โ„น๏ธ The dashboard uses a product data API at 20 tokens/minute, max stockpile 1,200. Daily capacity ~28,800 tokens. Current usage after skip logic stabilises: ~6,000โ€“8,000/day. Significant headroom remains for growth.

๐Ÿš€

Future Roadmap

Current build is a solid v1 โ€” live data, real-time scanning, accumulating DB, meaningful scoring. Here's what comes next, ordered by impact.

๐Ÿ—„๏ธ DB Accumulation for Generics & Private Label
Warehouse and Products already accumulate. Generics and Private Label follow the same pattern โ€” once their DBs fill, token costs drop 80% and results get richer daily. Expected: 4โ€“5ร— more products visible within one week.
๐Ÿ“ฆ Price List Analyzer โ€” Supplier CSV Matcher
Upload a supplier's price list (CSV/Excel) โ†’ system matches each UPC/EAN to an Amazon ASIN โ†’ pulls live Buy Box price โ†’ calculates margin per unit automatically. Turns a 2-hour manual spreadsheet job into a 30-second scan. Highest-value feature for active wholesale sourcing.
๐Ÿ“Š Increase API Token Plan
Current plan: 20 tokens/min. Upgrading to 100 tokens/min lets us scan more categories, pull more ASINs per category (currently capped at 50), and run faster. Single biggest lever for expanding coverage. Even at 50 categories ร— 100 ASINs each, one full scan stays within the upgraded plan's budget.
๐Ÿ›’ Amazon SP-API Integration
Amazon's Selling Partner API gives access to your own account: actual FBA fees (not estimated), sales velocity on products you sell, inventory levels, reorder suggestions. Requires approved seller account โ€” pending PrimeEdge Distribution approval. Once live, margin calculations become precise not estimated.
๐Ÿ”Œ Supplier API Integrations
Connect to distributors (PrimeEdge, Faire, Essendant) via their APIs. Dashboard automatically pulls live wholesale pricing for identified products โ€” and calculates real margin in real time. Would also enable automatic reorder alerts when inventory runs low.
๐Ÿ“ˆ Price Trend Alerts & Monitoring
Since we accumulate data daily, we can track: BSR trend over 14 days, Buy Box price drift, new competitor entries, seller drops. Eventually: SMS or email alert when a monitored product hits your target price or a major competitor drops out of the listing.
๐Ÿ” Free Price Data Alternative
Currently using Buy Box price (index 18) at 1 token per enrichment. Index 33 may provide similar data free as part of the base product response โ€” no stats call required. If viable, this cuts enrichment costs ~50% across all scanners, effectively doubling scan coverage for the same token spend.
