If you publish on more than one platform, your numbers are scattered across several dashboards. A simple monthly routine puts them in one place and shows what is working.
Collect the reports
Once a month, download the sales report from each platform you use. Save the original files with the platform and month in the name, such as kdp-2026-09.csv. These are your records, so do not edit them.
Use one set of columns
Platforms use different headings for the same idea. Decide on five columns: date, title, platform, units and royalty. Map each report to those columns. Note the currency of each, because royalty in pounds and royalty in dollars cannot be added together.
Combine them
Load the files into the sales dashboard. It maps the columns, totals units and royalty by book and by platform and exports a summary. Your files are read in your browser and are not uploaded.
Read the numbers sensibly
- Compare whole months. Single days are noisy.
- Look at royalty per copy as well as units, since format and platform change it.
- Expect delays: payments arrive after the sales month, and returns can reduce a month later.
- Check that every platform is in the table before you draw conclusions.
Act on what you see
If one platform sells much better, look at why: price, category or promotion. If a format earns very little per copy, check the price against the printing cost with the pricing guide. Our sales reports article shows the column differences in detail.
