When the Numbers Don’t Add Up
Can independent authors trust their book sales reports?
Writing fiction requires imagination. Checking the sales figures ought to require rather less.
An indie author opens a dashboard to see how many books have sold that day. Perhaps enough to justify a celebratory coffee. Perhaps enough to suggest that a stronger drink would be appropriate. Perhaps none at all.
We've all done it, many of us do it every day. Some of us do it every hour and a few of us do it several times an hour.
Been there. Done that. Not a millionaire... yet.
But what happens when the figures themselves are wrong?
It is a reasonable question. Independent authors depend on digital retailers and distributors to record purchases, calculate royalties and tell us what we have earned. We can check our bank accounts against our royalty statements. Checking those statements against every actual purchase is considerably harder.
Most of us have no independent record of what happened at the checkout.
When the dashboard gets it wrong
There have been reported problems with sales reporting, including a recent example involving Amazon.
In May 2026, it was revealed that publishing website Author Media reported that Draft2Digital had confirmed discrepancies in Amazon’s daily sales reporting. According to that account, some authors were seeing daily figures around 50 per cent below their actual totals. This was attributed to an Amazon backend tracking error which occured because of a reporting back-end infrastructure shift. In other words, the data was screwed up. As an ex-programmer, I've seen this happen before and usually the fault is spotted after data testing procedure.
That is a substantial difference if you are trying to decide whether an advertising campaign is working.
However, the account also made an essential distinction: final month-end figures were reported to reconcile correctly. An inaccurate dashboard did not, in that instance, establish that authors were receiving incorrect royalty payments. The published report attributed confirmation to Draft2Digital correspondence shared by authors.
Even so, a temporary reporting error matters. Authors make decisions with those figures. A campaign that appears to be failing may be stopped. A promising book may be discounted. Money may be spent trying to solve a problem that exists in the reporting system.
A dashboard can influence a business long before the final statement arrives.
A more troubling allegation
An older case concerned Amazon’s former print-on-demand service, CreateSpace.
TCK Publishing founder Tom Corson-Knowles reported that an internal sales report supplied by a CreateSpace employee in September 2018 showed 1,654 sales of Unlimited Memory over five months that had not been reported or paid.
TCK said the royalties remained unpaid when it published its account. This was a publisher’s allegation concerning printed books, rather than a Kindle ebook case or an independently established finding of wrongdoing. Nevertheless, it describes a specific discrepancy and the publisher’s attempts to obtain an explanation.
It deserves attention without being stretched into proof that every disappointing sales report conceals missing money.
A missing sale needs an explanation
There are also routine reasons why a purchase may not immediately appear where an author expects it.
Amazon states that ebook orders are reported after the customer’s payment is confirmed, normally within 24 hours of purchase. Dates follow the timezone of the marketplace concerned. Its final monthly royalty reports are separate from the daily dashboard.
Those details matter. Before describing a sale as missing, an author needs to establish which book and edition were purchased, through which retailer, on what date and whether the transaction completed.
A reader’s receipt provides a useful starting point. A quiet afternoon on the dashboard provides considerably less.
The question of trust
What interests me is the position independent authors occupy.
We supply the book. The retailer handles the transaction. We then rely on the retailer’s records to discover how often that transaction occurred.
That arrangement can work perfectly well. But when figures appear inconsistent, an author needs a clear explanation and a practical way to investigate. “Please trust the system” becomes less reassuring when the system has already displayed the wrong numbers.
Clear incident notices, explanations of affected reporting periods and confirmation that corrections are complete would help. So would a straightforward process for tracing a disputed purchase.
Authors should approach discrepancies with evidence. Retailers should make that evidence possible to investigate.
I write stories in which appearances deceive and apparently ordinary events conceal something unpleasant.
When I open a sales report, I would prefer considerably less mystery.
