Tracking Your Author Income Across Platforms (Without Losing Your Mind)

authors publishing across multiple platforms need to know where their money comes from. This is how you do it.

The Multi-Platform Problem

Most successful dark romance authors are not publishing exclusively on Amazon KDP. They’re on Kindle Unlimited for some books, wide distribution for others, selling directly through their own store, potentially selling foreign rights, and generating income from Audible, Patreon, and other channels. Tracking revenue across all these platforms manually is — in practice — something most authors either do badly or don’t do at all.

This matters more than it feels like it does. Authors who don’t track where their income comes from can’t make intelligent decisions about where to focus promotional effort, which platforms to prioritise for their next release, or when a particular channel is declining and needs attention. Business decisions made on gut feeling rather than data are frequently wrong in ways that cost real money.

The Author Income Tracker Tool

SpicyPlot’s Author Income Tracker tool is a free, browser-based tracker that consolidates royalty and sales data across publishing platforms. It works without an account and without any data transmission — everything stays in your browser. You input your monthly figures from each platform, and the tool gives you consolidated income data, platform-by-platform trends, and a clear view of where your revenue is actually coming from.

What You Should Be Tracking

Revenue by Platform

Amazon KDP, Ingram Spark, Draft2Digital, Kobo Writing Life, Apple Books, your own direct store — each platform should be tracked separately so you can see month-over-month trends for each one. A platform that was your second-largest income source last year that has been declining for three consecutive months is a data point you need to act on, not something to notice when the annual totals are in.

Revenue by Book

Which titles are your strongest earners? Which books in your backlist are still generating meaningful royalties and which have effectively gone dormant? This data tells you where to focus promotional attention. A backlist title that’s still earning is a title worth running a promotion on. A new release that’s underperforming relative to your previous titles tells you something useful about either the book, the launch strategy, or both.

Revenue Trends

Month-over-month is useful. Quarter-over-quarter is more useful. Year-over-year is most useful. Seasonal patterns matter in romance publishing — romance generally spikes in January (new year reading), summer, and November/December. Knowing your own seasonal patterns, rather than relying on industry generalisations, lets you time your releases and promotional pushes more intelligently.

Making the Data Actionable

Once you have three to four months of consolidated data, you can start making decisions. Platform A is your highest earner but growing slowly — consider whether wide expansion would grow the total or just fragment it. Platform B had a spike last quarter that correlates with your launch activity — note what you did and replicate it. Your direct sales are growing month over month, which means your newsletter is doing its job.

The goal isn’t to optimise everything simultaneously — that’s how authors burn out. The goal is to identify the one or two highest-leverage actions you can take in the next quarter and take them with the confidence that comes from actual data.

A Note on Taxes and Record-Keeping

The Author Income Tracker is a planning and visibility tool, not an accounting tool. Keep your official records in a format your accountant or tax software can use. But using the tracker as a live dashboard — running it monthly, noting trends, making decisions — gives you a level of financial clarity about your author business that most indie authors simply don’t have. In a business where information asymmetry is the norm, that clarity is a genuine competitive advantage.
