Turn your dev work into clean invoices in minutes
Prismo keeps your clients, tasks, time logs, and invoices in one dark, fast surface so you stop reverse-engineering last month's hours from Git history.
Built by a freelance engineer, for freelance engineers.

Used daily by its founder, engineer formerly at
Made for modern technical freelancers
Shaped by the needs of independent engineers: relentless focus on billable hours, fast execution, and zero administrative drag.
Purpose-built for development
Designed to move fast
Crafted for precision
Why this matters
Freelance work is structured. Your admin isn't.
Everything about Prismo keeps the “work → hours → invoice” loop intact so you can explain every line item.
You track time in three places
Calendar invites, personal notes, and spreadsheets never match up.
Invoices take hours
You rebuild the story of your work from emails, PRs, and Slack.
You underbill
Small but real work—debugging, quick reviews, emergency calls—goes missing.
No full picture
There's no single view of hours → invoices → what's paid vs pending.
Loop
From tasks to paid invoice, in one loop
