ZEP is the software for management consulting, IT consulting and engineering. With ZEP, every hour is booked to a client and a project. Utilization, costing, invoicing and a real-time view of your margin all come out of that same entry.

Four product lines cover the path from the first booked project hour to organization-wide control. Each line has a defined scope. If you need more, you move to the next line and take your data with you — no tool break. All prices are per user and month, up to 25 % lower on an annual contract.

ZEP Track — Project Time Tracking · From time to insight.
from € 9.00 on an annual contract, € 12.00 monthly
Your team books hours to clients and projects, and budgets stay visible during the engagement instead of only in the final costing. Compliant working time, absences, overtime and the payroll export run alongside. The ZEP AI chat is included at no extra cost.

ZEP Control — Project Management · From plan to progress.
from € 19.00 on an annual contract, € 25.00 monthly
Project management with a commercial view: you plan work items and capacity, and see at the same time what an engagement earns. Revenue & Costs, utilization and the billable ratio come from the hours your team booked, not from a spreadsheet export. Everything in ZEP Track is included.

ZEP Operations — Professional Services Automation · From projects to profitability.
from € 29.00 on an annual contract, € 35.00 monthly
The entire project cycle in one central system: proposal, booked hours, travel expenses, supplier services, invoice and the export to project-specific financial accounting. The invoice comes from what was actually booked. Everything in ZEP Control is included.

ZEP Business — ERP for Professional Services · From billable to scalable.
from € 39.00 on an annual contract, € 45.00 monthly
Several legal entities. One system of record. Internal cost allocation, Document Management, the HR module and Resource Planning are included, as is every function from ZEP Operations. Support requests are handled with priority here.

  • Interface in German, English and French, configurable per employee
  • Help Center in German and English, Help Center AI, email and phone support
  • Employee administration including rights and role management

From ZEP Track onwards: project time tracking, project and client administration, assignment of employees to projects and tasks, marking hours as billable or non-billable, a time limit for retroactive booking, and the ZEP AI chat.

You don't need project hours? ZEP Clock starts at € 4.50 per user and month on an annual contract, € 6.00 monthly: working time, overtime, absences and the payroll export in one system. Travel Expense Management and the HR module can be added for € 2.50 per user each. ZEP Clock is a line of its own; a move into the project-based lines is not provided for. If projects play a role for you — today or in the foreseeable future — start directly with ZEP Track.

Target groups:

ZEP is built for project-based service providers with 5 to 250 employees, with a focus on management consulting, IT consulting and engineering. In other words, for companies that sell time and need to know what lies behind every hour: at ZEP, every hour goes to a client and a project, and from that same booking come utilization, costing, invoicing and a view of the margin.

This is aimed at executive management, operations and finance, who are accountable for the profitability of the project business, as well as project and delivery leads, who need to report progress, capacity and budgets reliably.

Four product lines cover different levels of maturity: ZEP Track (project time tracking), ZEP Control (project management with a commercial perspective), ZEP Operations (the entire project lifecycle from quote to invoicing) and ZEP Business (organizations with multiple legal entities). Developed and hosted in Germany, ISO 27001 certified.
