“Our hero product was still ‘profitable’ — from three price changes ago.”
Alto Home Goods built their FBA business on a storage range shipped in containers from Ningbo. The margin was healthy at launch. Then the supplier changed, freight rates moved, and the dollar swung — each shift small, none of them in the spreadsheet.
Three small changes, compounding quietly
A new supplier quoted 9% higher “because of materials”. Ocean freight crept up $1,900 a container across two renewals. And the payment currency moved 4% against the dollar. Any one alone was survivable — together they took 27 points of margin while the spreadsheet’s landed-cost cell, typed in 2024, never changed.
What caught it — feature by feature
The same three screens are on every account, including free.
Unit cost charted across shipments — the supplier’s +9% shows up as a visible step, not a buried cell.
Product catalog →Set a floor once; every new cost is checked against it — the drift gets flagged at shipment two, not shipment five.
Analytics & alerts →The number Amazon’s reports can’t show: profit after landed cost and fees, updating as costs move.
Marketplace profitability →“We repriced two SKUs, re-quoted the freight, and dropped the line that couldn’t be saved. The product is back at 29% — and this time we’ll know the day it slips.”
