Upload your Amazon unified transaction report and the engine works out what you really made — per product, per batch, to the cent.

Start with your Amazon transaction file

In Seller Central: Reports → Payments → All statements / transaction view, or the unified transaction report you download for a date range. Drop the CSV here — everything is calculated in your browser; the file never leaves your computer.

Your costs and batches are already loaded (Barnetts batch + Sellerboard estimates, all editable under Data). The moment the file lands, every screen fills in.

Profit Truth

Every product, what Amazon actually settled, what the goods cost, and what is left. Click any profit figure to see the per-unit bridge.

Profit unknown — no cost on file

These products sold, but with no landed cost anywhere (not even in Sellerboard) any “profit” would be fiction. Add a cost under Data and they join the table above as Estimated.

Monthly

Your business month by month — what sold, what Amazon charged, and what was actually made. Profit is computed by the batch engine running month by month in order, so a unit sold in May carries the cost of the batch it really came from.

Load a transaction file to see your months

Monthly figures come from your Amazon unified transaction report. Upload it under Data (the same file Home uses) and this page fills in — the Jan–Oct 2026 file gives you all ten months.

Fees

Every fee and charge in the file, three ways: what Amazon took overall, what it took per product, and the account-level charges month by month. All of it is Amazon's own numbers — Confirmed evidence. Costs that live inside your batches (like a courier duty bill) stay in Batches; they are not Amazon fees.

Account-level charges by month

Charges Amazon levied outside any product — storage, placement, subscription, AWD, the sea shipment's import charges. Always the whole file, month by month; the same charges itemised on Home.

Investment Position

Where the money in this file actually sits — recovered, still in stock, or gone — shipment by shipment. Profit and capital recovery are kept separate: a shipment can be profitable and still have most of its cash sitting in stock.

Still to recover is what remains of the cash you put in, after the settlement that batch has earned so far. Stock at cost is what the unsold units cost you. They differ by the profit (or loss) already made. Dead is the cost of units lost or damaged — reimbursements Amazon paid for them are already inside “Recovered”.

Estimated-cost products — profit so far only

These products carry a flat cost per unit (from Sellerboard), so profit on units sold is computable — but how many units were bought was never recorded, so their invested and stock position is unknown, not zero. Add purchase records and they move up into the tracked table.

Batches

Your batch catalogue — every shipment, what it cost and what is left. Cost lives on the shipment, not the product. Sales consume batches oldest-first (FIFO); refunds return units to the batch they came from; lost and damaged units post against their batch. Each card shows exactly how its unit cost was built.

Floor Prices

The lowest price each product can sell at without losing money — built from the fees Amazon actually charged you, not a fee table.

How the floor is built

Floor = (landed cost + FBA fee per unit) ÷ (1 − referral %). The regime floor uses the fee level Amazon is charging now: the engine reads that product’s orders backwards until the per-unit FBA fee changes — that unbroken run of orders is the current fee regime, and its typical (median) fee is what a sale today will actually pay. When Amazon raises fees — as it did on 15 October 2026 — the regime floor moves fully to the new level at once, instead of blending old and new fees for a month. A regime resting on fewer than 3 orders is marked thin: treat it as provisional. The average-fees floor is kept for reference. For a product held in several batches, this table uses the batch your next sale will come out of (oldest first) — every batch’s own floor is listed on its card under Batches.

Batches (shipments)

Each batch is one shipment from one supplier. A unit cost is a build-up of named cost parts (product, courier, duty…) — edit any part, add a cost you discover later (per unit, or as a total the app divides by the units), or add a shipment-wide cost and the app allocates it across the shipment’s products by value. The landed cost is always the sum of the parts, and every screen recalculates the moment you change one. A new shipment of the same product is a new batch — the engine consumes the oldest batch first.

Simple costs (no batch tracking)

One cost per product, used where batch history isn’t available yet. These start as Sellerboard COGS — Estimated, unverified. Replace them with invoice costs as you get them.
