The full ledger
Every book. Both editions. Page reads counted.
The free check reads one ads file and tells you the floor. The full version joins your KDP royalty and KENP reports with your ads reports and gives you the whole picture: what each title actually earned against what it actually cost, with Kindle Unlimited income where it belongs.
Being built now. The free break-even check is live and finished. This full version is in progress — nothing to buy yet, and I'm not taking presales for something that doesn't exist.
One email when it launches. No list, no newsletter, no drip sequence.

What the full version adds
- 01
Your whole catalog, not one report.
Every advertised title in one ledger, sorted by what it actually earned. The books quietly bleeding money stop hiding behind the ones that work.
- 02
Paperback and ebook counted as one book.
Amazon gives each edition its own ASIN and reports them separately. Your readers don't see two books, and neither should your ledger.
- 03
Kindle Unlimited income included.
Page reads are real money living in a different report. They're joined in and valued at the rate from your own statement — labeled estimated until Amazon settles the month, because Amazon itself doesn't publish it sooner.
- 04
Month over month, saved on your machine.
Each run is kept in your own browser storage, so the second month shows a trend instead of a blank page. Download the ledger file to keep it forever or move it to another computer.
- 05
Series view.
Book-one ad spend against whole-series income over a window you choose — labeled as a comparison, never dressed up as attribution Amazon can't provide.
- 06
Labels that tell the truth.
Observed, attributed, estimated. New campaigns get a grace flag instead of a verdict. Numbers still settling are marked as such, so you don't kill an ad on data that hasn't finished arriving.
Pay once. It's yours.
- Perpetual use — pay once, use it forever
- 12 months of updates and report-format fixes included
- If AuthorTally ever shuts down: a downloadable offline copy, promised in writing
- One license, one author — all your pen names count as you
- 30-day money-back guarantee, no questions
The subscription tools run $17 to $30 every month, forever, and most want access to your Amazon account to do it. This is $59, once, and all it wants is two files you already download.
Your numbers are nobody's business. Including mine.
Your report contents never leave your browser.
- No Amazon login, no account connection, no cookie access
- Files parsed on your machine — nothing uploaded, nothing stored, nothing to breach
- No analytics that can see your data; support uses an anonymized report you trigger yourself
- The only things I ever hold: your email, your license key, your payment receipt
Fair questions
What's the difference between this and the free check?
The free check reads one ads report and answers one question: which lines made money against your real royalty. It can't see Kindle Unlimited income, so its numbers are a floor. The full version joins your KDP reports too, so it can show actual per-book profit including page reads, group your editions, and remember last month.
Can it tell me which campaign caused which page read?
No, and nothing can — Amazon doesn't link a royalty row to a campaign. Campaign views use Amazon's attributed figures plus clearly labeled estimates. The per-book tally is the number you can trust, and it's the one that decides where your budget goes.
Does it work outside the US store?
Version one is amazon.com and USD only, and it says so plainly. Other marketplaces are first in line, driven by what paying customers actually ask for.
What happens after the 12 months of updates?
The tool keeps working — perpetual means perpetual. Updates and format fixes are included for a year. After that, major new versions are an optional paid upgrade at a discount for existing owners.
What if you stop working on it?
Because everything runs in your browser, I can promise what a subscription can't: license holders get a downloadable copy that works without my servers. Your tool can't die of someone else's business decision.
Who's behind this?
An engineer who publishes on the side. I ran ads on a book, watched the console report a fourteen-times return on a keyword that actually lost money, and worked out why: it was counting what the customer paid Amazon, not what Amazon paid me. This is the tool I wanted to buy.
