The smart solution for co-author royalty management

Calculate co-author royalties, track costs, and share data among contributors using a streamlined dashboard.

Royalty Calculating

Easily calculate everyone’s share of the royalties using imported Amazon KDP data. You can also manually add other income data and related costs to see your full financial picture.

Unlimited Contributors

Royalties can be calculated for an unlimited number of contributors per title. For added security, only the book owner has access to sales data and royalty percentages.

Generate Royalty Reports

Securely distribute customized royalty reports to your team. Contributors can see their share of royalties on the reports, but cannot view royalty percentages for anyone else.

“PD Abacus will save meaningful amounts of time for LMBPN® Publishing. The royalty calculation, confirmation and distribution process for our hundreds of books and audiobooks to dozens of authors has taken days of staff work each month. That process shrinks to a few hours with PD Abacus.”
