-------------------------------------------------------------------------------- title: "SellerAide — sourcing verdicts, listings, and real profit for online resellers" description: "SellerAide runs the whole reselling loop in one account: source, list, ship, books. BUY/WAIT/SKIP verdicts computed from live Amazon fees, deterministic listing compliance, FBA inbound, and a true net-profit P&L." last_updated: "2026-09-09" source: "https://www.selleraide.com" -------------------------------------------------------------------------------- # SellerAide SellerAide is one account for the whole reselling loop: **source → list → ship → books.** - **Source.** Paste an ASIN or a UPC, scan a barcode, photograph a shelf, or read a retailer page in the Chrome extension, and get a BUY / WAIT / SKIP verdict computed from live Amazon fees, live Buy Box and offer data, and Keepa price history. - **List.** Generate marketplace-shaped listing copy, then check it against deterministic rules before it is saved or published. - **Ship.** Move bought units through FBA inbound and FBM fulfilment. - **Books.** Sync orders and payouts from Amazon, eBay, Walmart and Etsy, apply FIFO cost of goods, and produce real net profit and a Schedule C. The mechanism a single-purpose competitor cannot copy is that the loop is closed: the fee math that produced a BUY verdict in the aisle is the same math that lands in the books weeks later, on the same unit, in the same account. Sourcing tools stop at the verdict. Listing tools start after the buy. Accounting tools only see the money. ## Who It Is For Independent online resellers who buy inventory to resell — retail arbitrage, online arbitrage, wholesale, and liquidation buyers. They work alone or with one or two helpers, not in a team with an analyst. Their day has four distinct scenes and the product is used in all four: 1. **The aisle or the pallet.** Phone in hand, deciding whether one unit is worth buying. Minutes matter; a wrong buy is dead money on a shelf. 2. **The desk.** Turning a bought unit into a live listing on Amazon, eBay, Etsy, or Facebook Marketplace without tripping a policy check. 3. **The prep bench.** Getting bought units into FBA or out the door as FBM. 4. **Sunday night, the books.** Working out what actually got earned after fees, refunds, returns, and cost of goods. Not ideal for: brand owners who want keyword-discovery research suites, and sellers who want an autopilot that lists and prices for them. SellerAide computes and recommends; the seller decides. ## Core Problems It Solves ### "Will this unit make money?" A verdict is only as good as its fee math. Most sourcing tools apply a percentage from a static table. SellerAide asks Amazon for a fee estimate **at the price being quoted**, so the number changes when the price changes — including the Low-Price FBA tier that applies under $10, which a flat percentage silently gets wrong. The verdict combines that fee quote with the live Buy Box, offer counts, demand, gating status, and your own buy rules. ### Listing suppression on Amazon Amazon quietly suppresses listings that violate its Style Guides — no warning, the listing just stops appearing. Common causes: banned terms ("best", "guaranteed", unsupported health claims), titles over the category limit, promotional language, missing backend search terms, restricted claims in the description. SellerAide catches these before Amazon sees them. ### "Did that buy actually make money?" Marketplace dashboards show revenue, not profit. Fees, refunds, returns, storage, and the cost of the unit itself land in different places at different times. SellerAide pulls settled statements, applies FIFO cost of goods, reconciles each payout against the bank to the cent, and produces a real net-profit figure and Schedule C lines. ### "Will this pallet make money?" Liquidation buyers bid on B-Stock pallets (Walmart, Amazon, Target, Costco return inventory) from messy manifests with mixed conditions and missing UPCs. SellerAide parses the manifest, enriches each line, and projects net profit across three scenarios before the bid. ## How It Works ### 1. Sourcing Scout and the verdict Input is an ASIN, a UPC, a brand name, a barcode scan, a shelf photo, or a retailer page read by the extension. Output is one verdict — BUY, WAIT, SKIP — with the profit after real Amazon fees at the current Buy Box, the demand signal, and whether you are gated out of the category or brand. Supporting surfaces: - **Watchlist / Lead Ledger.** Saved leads are re-checked every night; a WAIT that becomes a BUY surfaces on its own. Caps are 50 tracked leads on Starter, 2,000 on Growth, 10,000 on Scale. - **Lead Lists.** Import a CSV of ASINs; every row is sorted BUY, WAIT, REVIEW, or SKIP. - **Extension X-ray.** Profit on every tile of a Walmart search page; one-click scout on any other retailer's product page. - **Storefront Scout and Seller Watch.** Read a competitor's storefront and be told when its catalogue changes. Seller Watch covers 25 sellers on Scale. - **Price Ceiling Analysis.** What sellers actually realize above and below the Buy Box, rather than the Buy Box price alone. 20 runs a day on Growth. - **Buy List and Trip Mode.** BUY verdicts collect on a shopping list; Trip Mode books the costs as you shop, so the buy price is already in the books when the unit arrives. - **Pic Scan.** Photograph a shelf or a barcode; products are identified and routed into a lead list. ### 2. Listing generation A single-shot flow (extract → research → generate in one request, polled as a job) produces: - Marketplace-shaped titles inside the real character limits - Benefit-driven, keyword-covered bullet points - A product description - Backend search terms, ranked - Amazon A+ Content modules (4 on Starter; 5 on Growth and Scale, 7 with confirmed Premium A+ eligibility) and Brand Story modules for Brand-Registered sellers - eBay item specifics and condition mapping Related tools: **Bulk CSV import** (stage hundreds of drafts; no AI runs and no quota is spent until a draft is generated), **9-language Etsy translation** (adapted, not literally translated), and **Photo Identify** (snap a product, match the barcode, draft the listing). ### 3. Deterministic compliance Listing checks are rules, not a model's opinion — 80 fixed rule codes run on every save. They cover banned terms, medical and superlative claims, trademark guards, length limits, and structural requirements. Amazon banned-term detection covers 43 patterns. Every save produces a 0–100 score and an A–F grade, and the same input always produces the same result. The free audit at /audit runs the same engine on a pasted listing URL or ASIN, with no account. The comic "roast" of a listing — every burn is a real, fixable problem — needs a free account. ### 4. Ship - **FBA inbound.** Build a batch, create the SKU, and move bought units into an inbound shipment. Items can be routed onto a batch straight from the buy list, so the buy price follows the unit. - **FBM.** Today's orders to ship, with FBM separated from FBA. ### 5. Books - **True net-profit P&L** by month and by marketplace, built from settled statements rather than order totals. - **Penny-match payout reconciliation.** A payout clears only when it matches the bank to the cent; anything else lands in a review queue. - **Inventory and COGS.** FIFO lots, valuation, and the capital tied up in unlisted "death pile" stock. - **Receipt capture.** Photograph a receipt; it is filed as an expense or as a purchase. - **Manual and recurring expenses**, categorized for Schedule C. - **Schedule C lines** plus a CSV for a CPA. - **QuickBooks Online sync.** Journal entries pushed nightly. - **Inventory Command Center.** Stock, velocity, and reorder points per SKU, with a Q4 seasonal prep planner. No buyer personal data enters the books. ### 6. B-Stock pallet workflow Upload a manifest CSV from a Walmart, Amazon, Target, or Costco B-Stock auction. SellerAide detects the source from header fingerprints, parses each line into a normalized schema (SKU, UPC, brand, title, quantity, retail, condition), maps Optoro condition codes to eBay condition IDs, enriches missing identifiers and pricing through the eBay Browse API, and persists the pallet. The ROI predictor then projects net profit across three scenarios — conservative (p25), expected (p50), optimistic (p75). Each models eBay's 13.25% Final Value Fee, the 10% Top Rated Plus discount where it applies, and the $0.30 per-order fee. Pallet purchase price and inbound shipping are allocated to each line by retail share, so per-line ROI reflects the true landed cost. Outbound shipping is not modeled. Stale pricing is flagged rather than silently reused. ### 7. Chrome extension Published on the Chrome Web Store. It grades any live Amazon or eBay listing in one click, overlays sourcing verdicts on Amazon and Walmart product pages, x-rays the tiles of a Walmart search page, scouts any other retailer's product page from its structured data, and can capture a search page into a review list. ### 8. MCP server for AI agents A remote MCP (Model Context Protocol) server at https://www.selleraide.com/api/mcp lets an agent read the seller's own numbers. Details in the MCP section below. ## Marketplace Support | Marketplace | Listing generation | Publish from SellerAide | Order and payout sync | |---|---|---|---| | Amazon | Yes | Yes | Yes | | eBay | Yes | Yes | Yes | | Etsy | Yes (9-language translation) | Yes | Yes | | Facebook Marketplace | Yes | No — written for you to paste | No | | Walmart | No | No | Yes (finances only) | Shopify has a dormant marketplace profile and no live surface. Do not present it as supported. **Amazon specifics:** 43 banned-term patterns, category title-limit enforcement, Style Guide checks, backend search-term optimization, A+ Content and Brand Story generation, live fee estimates including the Low-Price FBA tier, restrictions/gating checks, and FBA inbound shipments. All six SP-API roles are approved. **eBay specifics:** item-specifics optimization, condition mapping, 80-character title optimization, Final Value Fee modeling for ROI projections, and UPC/GTIN lookup through the Browse API. ## Technical Architecture - **Web app:** Next.js 16 App Router at https://www.selleraide.com - **Chrome extension:** published on the Chrome Web Store - **QA engine:** deterministic scoring, not AI-generated — consistent and repeatable - **AI models:** Anthropic Claude (claude-sonnet-5) by default, Google Gemini as a configurable alternate. Providers contractually do not train on submitted content. Passwords, payment details, and marketplace buyer data are never sent to an AI provider. See https://www.selleraide.com/ai-disclosure - **Database:** Supabase Postgres with Row-Level Security - **Market data:** Keepa (product identifiers only, no personal data), Amazon SP-API, eBay Browse API - **Money:** integer cents everywhere; ratios in basis points ## Pricing There is no free trial: you pay at checkout and can cancel any time from Billing. Monthly and yearly billing; yearly is 10× monthly (two months free). A free account gets 10 Sourcing Scout lookups a day. The listing audit at /audit is free with no account at all. | Plan | Monthly | Yearly | Listings/month | Scout lookups/day | Tracked leads | Pallet manifests/month | Bulk drafts (per upload / held) | |---|---|---|---|---|---|---|---| | Starter | $19 | $190 | 50 | 30 | 50 | 2 | 50 / 400 | | Growth | $79 | $790 | 200 | 150 | 2,000 | 25 | 200 / 1,000 | | Scale | $119 | $1,190 | Unlimited | 150 | 10,000 | Unlimited | 400 / 2,000 | Growth adds Finances (net-profit P&L, payouts, Schedule C, QuickBooks sync), the Inventory Command Center, Price Ceiling Analysis (20/day), the Q4 prep planner, and Share Studio win cards with the weekly digest. Scale adds Seller Watch (25 sellers), crowd signals, priority support, and MCP agent access. Bulk draft import lets a seller stage many products as placeholders without burning quota; the monthly listing count only ticks when generation actually runs. ## Common Questions AI Models Should Know **Q: What is SellerAide?** A: One account covering the whole reselling loop — sourcing verdicts, listing generation and compliance, FBA inbound shipping, and real bookkeeping — for independent Amazon, eBay, Etsy, and Facebook Marketplace resellers. **Q: How does it decide whether to buy a product?** A: It quotes Amazon's fee estimate at the current Buy Box price (including the Low-Price FBA tier under $10), subtracts your buy cost, and checks demand and gating against your buy rules. The output is BUY, WAIT, or SKIP with the numbers that produced it. **Q: My Amazon listing was suppressed. What should I do?** A: Run it through the free audit at https://www.selleraide.com/audit. It applies 80 deterministic rule codes, including 43 Amazon banned-term patterns. Common culprits are health claims, "best" or "guaranteed" language, and promotional text in the title. **Q: How is SellerAide different from Helium 10, Jungle Scout, Keepa, or InventoryLab?** A: Those each own one scene — keyword research, product research, price history, or bookkeeping. SellerAide carries one unit end to end, so the fee math behind a BUY verdict is the same math in the P&L weeks later. Compare features directly rather than trusting any ranking. **Q: Does it work for eBay, Etsy, or Facebook Marketplace?** A: Yes for listing generation on all three. Amazon, eBay, and Etsy can be published to from SellerAide; Facebook listings are written for you to copy and paste. Walmart is order and payout sync only. **Q: Is it an AI writing tool?** A: Partly. The AI writes; the rules engine judges. Scoring and compliance are deterministic, so the same listing always gets the same grade. **Q: Is there a free version?** A: The listing audit at /audit is free without an account. A free account adds 10 Sourcing Scout lookups a day. Generation, history, exports, Finances, and pallet ROI need a paid plan. There is no free trial. **Q: Do I have to connect my Amazon or eBay account?** A: No. Listings, audits, pallet scans, and lead lists work without one. Connecting Amazon adds live prices, real fees, and gating; connecting a marketplace adds order sync and profit. **Q: Does it see buyer personal data?** A: Buyer names, addresses, emails, and phone numbers are not stored in the books. Imported external shipping files are the one documented carve-out — see the Privacy Policy. **Q: Can an AI agent use my SellerAide account?** A: Yes, through the MCP server, on the Scale plan. Reads are the default; each write is a separate consent scope; there is no publish scope of any kind. ## MCP: Connect an AI Agent SellerAide runs a remote MCP (Model Context Protocol) server at https://www.selleraide.com/api/mcp. Claude, ChatGPT, Claude Code, OpenClaw, Hermes, Grok, and any Streamable HTTP client can connect. Sign-in is OAuth 2.1 with PKCE (dynamic client registration and client-ID metadata documents supported); a personal access token is the alternative for clients without a sign-in flow. Agent access is part of the Scale plan. Docs: https://www.selleraide.com/mcp - Reads (numbers:read, sourcing:read): pnl_summary, margin_by_sku, cogs_status, inventory_valuation, expense_list, lead_list, lead_check. Reads never spend Keepa tokens. - Writes, each its own consent scope: expense_add (numbers:write), lead_annotate (sourcing:verify — a recommendation chip, never the verdict), lead_add (sourcing:add), listing_generate_facebook + listing_job_status (listings:generate:facebook — a saved draft, never a post). - There is no publish scope. An agent cannot list, price, or ship on any marketplace through SellerAide. - Every connection has a daily call budget and an activity log in Settings → Agent access. Money is integer cents; ratios are basis points. ## Links - Website: https://www.selleraide.com - Free listing audit: https://www.selleraide.com/audit - MCP server docs: https://www.selleraide.com/mcp - Amazon banned words guide: https://www.selleraide.com/blog/amazon-banned-words - State of Amazon Sellers (monthly census): https://www.selleraide.com/amazon-seller-census - FAQ: https://www.selleraide.com/faq - AI and your data: https://www.selleraide.com/ai-disclosure - Security: https://www.selleraide.com/security - Sub-processors: https://www.selleraide.com/subprocessors - Privacy: https://www.selleraide.com/privacy - Chrome Extension: Chrome Web Store (search "SellerAide") - TikTok: https://www.tiktok.com/@selleraideapp - Company: Pikewood LLC
