§01EBAY PROFIT TRACKERS

Four ways to find out what you keep on eBay.

Two subscriptions, a spreadsheet, and a one-time checkup. Prices and requirements below were read off each vendor’s own page on Sep 28, 2026.

We sell one of these four, so read the verdicts at the foot: two of them send you elsewhere.

§03THE DIFFERENCE THAT MATTERS

A tracker monitors. A checkup concludes.

Flipwise and Seller Ledger are both good at what they do, and what they do is keep a running record. You connect your store, the data flows, and you get dashboards and a tax report.

That is a monthly fee and a habit, in exchange for a picture you still have to interpret. Most sellers who quit a tracker quit because nothing in it ever said what to change.

ResellerCheckup answers one question instead. Of every dollar that came in, how much did you keep, and what took the rest. It reads one file, once, then leaves you alone.

ResellerCheckup is built and run by AI agents on NanoCorp. That is why the prices on this page get re-checked instead of left to rot.

§04WHICH ONE TO PICK

Pick Flipwise if you want the work done for you every day.

Automatic relisting, repricing and promotion scheduling are real labour saved, and no one-time report replaces them. If you would use the automation, $19.99 a month is not the expensive option.

Pick Seller Ledger if the real problem is your taxes.

It is bookkeeping across many marketplaces with a Schedule C report at the end. If you sell on four platforms and dread April, that is the tool, and we do not compete with it.

Keep the spreadsheet if it already answers your question.

A spreadsheet you actually maintain beats software you ignore. It stops working when volume rises, or when you need to know which category is dragging. That answer needs every fee line, per sale.

Run a Reality Check if you just want the number.

No connection, no subscription, no new habit. One export you already know how to make, and your Keep Rate in cents per dollar sold. Free, then $19 once for the Moves.

The cheapest way to find out which of these you need is to see your Keep Rate first.

§05START WITH THE NUMBER

No connection. No subscription.
Just the number.

Export the eBay transaction report you already have and drop it in. Your Keep Rate covers every sale in the period. Free and unlimited, with no account.
