Perpendis › Custom work
Custom work and consultation.
The tools are free and run themselves — the royalty converter, the array diff and the demo produce their results as you use them. This page is for the hands-on work that sits beyond them.
Royalty & statement work
Send us one royalty statement and we'll return a reconciled, tied-out Excel tape — the combined earnings tape the free tool makes — your first report on us. If it saves you time, we'll talk about the rest.
- It saves the hours a statement pile costs in junior or billable time — and the $79–349 a workbook tool charges for the export alone.
- The tie-out proves the numbers are self-consistent with what was printed; it cannot prove the source reported you correctly.
- Don't send any statements yet. Reply first and we'll send a secure link — files in the free tool are parsed in your browser and never uploaded.
Verification & evidence work
- Only computational integrity is a real measurement today — a bit-exact re-verification,
sealed with a signature anyone can check. The other seven domains are
sampledata, labelled that way wherever a score appears. - A valid signature is not a pass, no certificate is issued, and no regulation requires the pack. It is evidence — someone still has to decide what it is worth.
Getting in touch
Tell us what you're working with and what you need — a few lines is plenty. A person reads it and replies, usually within a business day. Please don't send credentials, customer data or statements in a first message.
