Real profit, real fees, real VAT — not Amazon's guesswork. MarginLens tracks every referral fee, FBA charge, and VAT reclaim so you always know what you actually made.
Every referral fee, FBA charge, and storage cost tracked to the penny — settled figures shown separately from estimates, always.
See true cash flow and after-reclaim profit side by side, so you know exactly what's yours today and what's coming back from HMRC.
Unusual fees, thin margins, and high return rates surfaced automatically — not buried three tabs deep in Seller Central.
Days-of-stock, reorder points, and incoming shipments in one place — know what's about to run out before it does.
A fast web dashboard that fits a phone screen, with a new-sale chime while it's open — no app to install, nothing to update.
No manual "sync" button to remember. Your numbers stay current in the background, automatically.
MarginLens started as a private tool to answer one question honestly: "did I actually make money on that sale?" Turns out that's harder to answer than it should be.
MarginLens is an analytics service for Amazon sellers, built and operated by ME ASPECT LTD, a UK company. We connect directly to a seller's Amazon Seller Central account via Amazon's Selling Partner API and turn their raw order, financial, and inventory data into a single dashboard showing true profit, VAT position, and stock health.
Sellers authorise MarginLens to read their own Seller Central data (orders, settled financial events, fees, inventory and advertising spend) through Amazon's standard OAuth flow. We never see customers' personal details — no buyer names, addresses, phone numbers or emails — only the order, financial and stock data needed to work out profit. Every figure shown is traced back to a real Amazon transaction, and anything estimated is labelled as an estimate.
Amazon Advertising spend (Sponsored Products, Brands and Display) is pulled in alongside the profit figures, so sellers see true, ad-inclusive net profit per SKU in one place.
