An Amazon FBA profit tracker is a tool that brings together your sales revenue, Amazon fees, product costs and other relevant costs in one place — so you can understand actual profit rather than looking at revenue alone.
When a sale is made on Amazon FBA, the amount that reaches your bank account is already reduced by Amazon's referral fee, the FBA fulfilment fee, and any applicable charges. The revenue figure shown in Seller Central reflects what Amazon collected from the buyer — not what you keep. A profit tracker accounts for those deductions, and for your cost of goods, to show what you actually made on each sale.
Amazon FBA profit is calculated by starting with sales revenue and subtracting the fees Amazon charges and the costs you incurred. Here is how SaleslyPro calculates it per order:
SaleslyPro uses actual fee data from Amazon's Finance API for the referral fee and FBA fulfilment fee figures — not category-based estimates. Cost of goods is entered once per product by the user.
Understanding whether an FBA business is profitable requires more information than Seller Central provides by default. Here are the practical reasons sellers use a profit tracker:
Revenue is the amount Amazon collected from your buyers. After referral fees, FBA fees and product costs are deducted, what remains can be significantly lower. Sellers who only track revenue can have healthy-looking sales figures while their margins are thin.
Amazon charges a referral fee on every sale and a per-unit FBA fulfilment fee on every order it ships. These are deducted before you receive a payout. Without tracking them, it is difficult to know what you are actually keeping per sale.
Your cost of goods — what you paid to source or manufacture each unit — needs to be matched against sales to calculate profit. This is not information Amazon holds. It has to be added separately.
Returns result in refunds to buyers and may result in units that cannot be resold. Reimbursements from Amazon for lost or damaged stock partially offset those losses. Both affect actual profit.
When units you send to an FBA warehouse are not all checked in, your available stock is lower than expected. Tracking discrepancies per shipment helps identify what has not been received and its value.
At low order volumes, spreadsheets can work. As order count grows, keeping fees, refunds, COGS and inventory all accurate manually becomes time-consuming and error-prone.
What SaleslyPro tracks
The following are existing features in SaleslyPro, each pulling data from Amazon or using cost information you provide.
Every Amazon order syncs automatically. Sales, quantity, order status and revenue are all pulled directly from your Seller Central account.
Actual referral fees and FBA fulfilment fees from Amazon settlements are used in the profit calculation — not estimates.
Profit is calculated per order after fees and COGS. ROI and margin figures are available across selectable time periods.
FBA inventory levels are tracked alongside your cost prices. Stock value, remaining units and status are visible per product.
Shipments are tracked against what Amazon checked in. Discrepancies — where units you sent were not received — are highlighted with value at risk.
Customer returns are tracked with disposition (sellable or damaged) and the net cost of each return is calculated.
Reimbursements for lost or damaged FBA stock are pulled from Amazon and shown separately so you can see what has been recovered.
Payout and settlement data from Amazon is pulled in to provide accurate fee figures for orders in each settlement period.
A morning summary of the previous day's sales, profit and units is available in the app each day without needing to open Seller Central.
Current Buy Box prices are available per ASIN in the product tracker, giving context on market pricing alongside your cost data.
These two terms are often used interchangeably, but they measure different things:
Revenue
The money generated from sales — the amount Amazon collected from buyers.
Profit
What remains after relevant costs and Amazon fees are deducted from revenue.
Sellers who focus on revenue alone may not notice that individual products or product categories are not generating a return after costs. Tracking profit per order gives a more accurate picture of business performance.
Spreadsheets can work at low order volumes. As a business grows, keeping the following accurate manually becomes increasingly time-consuming:
SaleslyPro automates the Amazon data sync once your account is connected. Orders, fees, settlements, inventory, returns and reimbursements are pulled in automatically. You still need to enter your cost price per product once — that information is not held by Amazon — but after that, profit calculations update automatically as new orders arrive.
Who it's for
UK Amazon FBA sellers
SaleslyPro is built for UK-based sellers. Figures are shown in GBP and it connects to the Amazon UK marketplace via the SP-API.
Sellers managing multiple products
Profit, ROI and stock are tracked per ASIN, making it possible to see which products are performing well and which are not.
Sellers who want to understand true profit
If you want to see what you are keeping after Amazon fees and product costs, rather than just what Amazon reports as revenue, SaleslyPro calculates that for you.
Sellers moving away from spreadsheets
Once Amazon is connected, orders, fees, inventory levels, returns and reimbursements all sync automatically. Product cost prices still need to be entered once per item.
Sellers tracking inbound shipments
If you want to know whether all units you sent to an FBA warehouse were received and checked in correctly, SaleslyPro shows discrepancies and value at risk per shipment.
