An Amazon seller’s margin dies a death by a thousand cuts. Here is the complete map of fees, from the most visible to the most insidious.
Visible fees
- Referral fee: a percentage of the price, by category.
- FBA fees: per unit, based on size/weight.
- Storage: monthly + long-term.
Semi-visible fees
- PPC advertising: often the second-largest cost after COGS.
- Returns: processing fees + products that sometimes cannot be resold.
- Customer refunds: they affect your real net figure.
Hidden fees
- Disposal / removal order fees
- Labeling and prep fees
- Amazon adjustments and payout discrepancies
- Lost/damaged inventory left unclaimed
Why a spreadsheet is no longer enough
These fees appear on different report lines, on different dates. Aggregating them by hand is error-prone. Profit+ automatically matches each fee to the right product and the right period, for a reliable net margin.
