SellPulse - Amazon FBA & Walmart Profit Analyzer

About

SellPulse is the fastest way to know if an Amazon FBA or Walmart WFS product is worth selling.

Open any Amazon or Walmart product page and SellPulse opens beside it. The page shifts left so nothing gets covered, the panel docks on the right, and the analysis appears in about a second.

WHAT YOU GET, ON EVERY PRODUCT

• Real-time profit & ROI — using the actual Keepa-reported FBA fee for the listing's exact dimensions, not a weight-based estimate
• BUY / HOLD / AVOID verdict at a glance, with the reasons spelled out
• All offers, sorted by price — FBA vs FBM badges, buy-box winner, lowest price, seller name + star rating
• Cumulative stock at every price tier, so you can answer "how many units undercut me?" in one look
• Listing eligibility — is your Seller Central account approved to list this ASIN? Restricted? Approval required? Answered from the panel without leaving the product page
• Buy-box and price history charts (90 days, Keepa data)
• Sales rank, monthly sold estimate, review count and star rating
• ROI calculator — change your cost or selling price and the numbers recompute live

DESIGNED FOR ARBITRAGE & WHOLESALE BUYERS

• Auto-detects when you land on a product, opens the side panel automatically
• Auto-closes when you navigate away from a product page
• Same flow on Walmart.com (WFS calculations included)
• Works in EN, PT-BR, and ES

ACCURATE BY DESIGN

• FBA fees come straight from Keepa's listing-level pickAndPack value (not weight tables that miss oversized rules)
• Walmart WFS fees use Walmart's real fee schedule
• Stock counts use Keepa precise tracking up to 30 units, then "30+" for higher (matches SellerAmp behavior)
• No mock data — if a source fails, you see a clear error instead of fake numbers
