Professional Service Automation
PSA Software for Project-Based Service Providers
Projects, resource planning, time tracking and billing - QUANTICAL.ERP, the central PSA solution.

QUANTICAL.ERP is the gold standard among Professional Service Automation solutions
PSA solutions like QUANTICAL.ERP unite the core elements of professional services in one platform: clients, employees, projects, invoicing, receivables management, timesheets, controlling & P&L, budgets, leave management, sick leave and much more. QUANTICAL.ERP automates every business process so you can focus on your core business.
What is Professional Service Automation?
Professional Service Automation, or PSA, brings the business processes of project-based service firms together in one piece of software. Project planning, time tracking and billing no longer run in separate programs but on the same data.
The difference is continuity. A logged hour belongs to the project calculation, the utilisation figure and the next invoice right away. Nobody copies numbers by hand. For consultancies, IT service providers and agencies this means the margin of a project becomes visible while it runs, not at the year-end close.
What a PSA solution has to do
Four areas carry the daily work of a project-based service firm. QUANTICAL.ERP covers them without an interface.
Resource and capacity planning
Who is free next week, who is overbooked? Every employee's utilisation sits next to the open projects. Bottlenecks show up before they become a problem.
Project time tracking
Hours are logged where they happen. Entry works in the browser and on the phone. Every entry carries the project, the activity and whether it is billable.
Invoicing and receivables
The invoice comes straight from the billable hours, with no intermediate step. Open items and incoming payments live in the same system. You see what is still outstanding without asking accounting.
Controlling and the P&L
Revenue, cost and margin are ready per project and for the whole firm. A day-accurate forecast shows where you will end the year. That replaces a gut feeling with a sound number.
Common questions about PSA software
What does PSA software cost?
The market range is 15 to 100 euros per user per month, depending on the feature set. QUANTICAL.ERP costs 12.90 euros per user per month, with every feature included. There is no tier where important modules are billed on top.
Who is Professional Service Automation for?
For companies that sell their work in projects and hours. That includes consultancies, IT service providers, agencies and law firms. A company that manufactures goods or works in retail needs a different system.
How does a PSA solution differ from a time-tracking tool?
A time-tracking tool collects hours. A PSA solution connects those hours to projects, clients, invoices and the P&L. Time tracking is one part of it, not the whole.
What is the difference between PSA software and an ERP system?
A classic ERP is built for inventory, manufacturing and warehousing. PSA software is built for project-based services, meaning hours, utilisation and project margin. QUANTICAL.ERP brings both together for firms that sell their work in projects.
Which functions should PSA software cover?
Project management, resource and capacity planning, time tracking, invoicing and a controlling view with a P&L. If one of these is missing, separate tools and double data entry come back.
How do you create a timesheet for a project?
In a PSA solution you pick a project and a period, and the timesheet is ready as a print-ready PDF. The client signs it, and the hours stay tied to the project and the invoice.
