GetValue Consulting
Most sellers price against a fee table that was wrong the year it was written. We compute yours against a rate card we date, cite, and re-read.
Method
One is a forecast. The other is arithmetic. We lead with the arithmetic, because you can check it before you trust us.
A referral tier applied the wrong way. A carton sitting a fraction over a size-tier boundary, on every unit, permanently. A reimbursement basis you never declared. No estimation involved — it either matches the published rate card or it doesn't.
Share of shelf, keyword coverage, listing gaps against named competitors in your category. Genuinely useful, and genuinely a model — so we quote it as a range and say what it assumes.
Worked example
Amazon runs two different tiered referral structures and distinguishes them only by wording. Clothing reads "products with a total sales price" — the bracket re-rates the whole price. Jewelry reads "portion of the total sales price" — genuinely marginal. Same table, opposite arithmetic.
jewelry @ $400.00 mode marginal $ 250.00 @ 20% = $50.00 $ 150.00 @ 5% = $7.50 fee $57.50 flat model $80.00 → overstates by $22.50/unit
A flat-20% model is wrong by $22.50 on a single unit. Run that across a catalogue and a year and it stops being a rounding error — it's the difference between a product you keep and a product you kill.
Worked example, in the wild
We pulled Amazon's apparel dead zone across socks and leggings. adidas, Hanes, Reebok, Balega and Amazon's own private label are all priced inside it right now — one of them by three cents, at a cost of $1.38 per unit.
Credential
Every fee figure we use carries its source, its tier, and the date it was read. Where we've only got a third-party source, it says so, and it doesn't go in a client report until it's been confirmed against the primary rate card.

Published e-commerce fee tables are almost universally undated and uncited. They are wrong within a year and nothing in the file reveals it. Making provenance a visible field is the entire difference between a reference and a guess — and it's the part that has to be maintained, which is why so few are.
