PSA (professional services automation) is the operational backbone of a services business. It tracks time, manages projects and contracts, calculates customer profitability, and feeds billing — so the work a tech does on a Tuesday turns into a line item on an invoice on Friday without anyone re-keying it.
IT Glossary
What is PSA?
Professional services automation — the system that connects time, tickets, contracts, and billing into one customer view.
What the practice is actually for.
- PSA is where margin lives or dies — every minute of unbilled work is margin lost
- Without integrated time + contracts + billing, profitability reporting is a quarterly spreadsheet project
- PSA tied to RMM lets a ticket open from an alert, accrue time, and bill at the right rate automatically
The practical version.
Tickets, time, contracts, rates, and Stripe billing live in one data model. Time captured on a ticket flows to an invoice at the right rate. Customer profitability dashboards update live as work happens — not in a nightly batch.
