Know when your profit margin drops, before your monthly P&L shows it.
Short answer
Notifcentral calculates margin after Amazon fees, cost of goods and advertising spend, and pushes an alert when it drops by more than your threshold, which is ten percentage points by default. A revenue dashboard can show sales rising while margin falls, so this alert tracks margin.
How Notifcentral detects it
Data source
Profit reconciliation across fees, COGS and ad spend
How often
Every 6 hours
Margin is computed from settled financial events, your imported COGS, and advertising cost, then compared against the prior period. A drop beyond the configured threshold raises the alert. The default is a ten percentage point move.
What the alert looks like
These are the notification strings the app sends. The wording is exact; the values are examples.
Margin dropped
Margin fell 11.0 pp - now 21.0%, down from 32.0% yesterday.
What it costs to find out late
Revenue can rise while you lose money.
A fee increase, rising ad spend and a competitor's price cut can all happen in the same week. Each one alone is small, but together they can make a product unprofitable while sales keep rising.
Small cost increases add up.
A $0.20 pick-and-pack increase, a supplier price rise and a discount you forgot to end do not trigger any notification from Amazon, and none of them show up until you close the monthly P&L.
What to do when it fires
Import your COGS
Margin is only accurate if your costs are. The app imports a COGS sheet by CSV and shows what percentage of your catalogue has costs.
Check fee alerts from the same window
A margin drop with a fee change in the preceding days usually has a single cause, and the fee alert already has the before/after numbers.
Look at ad spend, not just fees
The profit view shows net after advertising and reports TACoS. If margin dropped and no fee changed, ad spend is the usual cause.
Questions about profit margin alerts
A ten percentage point drop by default.
Yes. Profit is computed after fees, COGS and advertising, and the app reports net-after-ads alongside TACoS.
Margin needs a cost basis to be meaningful. Without COGS the app tells you coverage is incomplete rather than reporting a confident but wrong number.
