Tallyhook puts a price on AI coding work
A billing tool for dev agencies that reads Claude Code and Codex session logs, assigns usage to clients by repository, and exports marked-up invoice lines.
Field notes
Tallyhook maps coding sessions to clients through their Git remotes, so an agency can classify a repository once and have earlier and future sessions follow that assignment. Its example CSV separates session counts, list price, and marked-up billable totals, including a report of 59 sessions costing $600.42 before markup. The privacy section says transcripts and later prompts remain on the laptop, while selected metadata—including token counts, timestamps, branches, and tool-call counts—is uploaded.
