ZEP review

What ZEP actually does

ZEP is a German cloud application for recording time twice over: the working hours an employer is legally obliged to document, and the project hours a professional services firm needs in order to bill and to know whether a job made money. Entries are made in a browser, in the mobile app or at a physical terminal, and each one carries a customer, a project, a sub-project and an activity type, plus a flag for whether it is billable.

That structure is what the rest of the product runs on. Project controlling sets recorded hours and costs against the budget so a project manager can see margin erode while there is still time to act. Rate tables turn approved hours into invoices without re-keying. Travel expenses and receipts, on the top tier, land in the same project cost view. Exports go to DATEV and Lexware in the shape German accountants expect, staff data comes in from Personio, and a REST and SOAP interface exists for anything else. The vendor reports more than three thousand customers and fifty thousand users, mostly in the German-speaking market, and the software is available in German, English and French.

Key features

The modules split cleanly between compliance and project economics:

• Working-time tracking to the minute with statutory break and maximum-hours monitoring
• Project time recording against customer, project, sub-project and activity, with billable and non-billable separation
• Project controlling comparing recorded cost and revenue against budget
• Invoice generation from approved hours using hourly and daily rate tables
• Travel expense and receipt capture feeding the same project cost view
• Optional modules for absences and overtime, resource planning, document management, proposals and ticketing

Who it's for

The fit is a European professional services business with somewhere between twenty and a few hundred staff whose revenue is recorded hours: an agency, an engineering office, a law or tax practice, an IT consultancy. Two pressures make it worth the setup effort at once, a duty to document working time under German and EU rules, and projects whose profitability is invisible until someone reconciles timesheets against the budget. Firms already living inside DATEV, Lexware and Personio get the smoothest run, because the exports match what their accountant and their HR system expect.

It is the wrong purchase for a small distributed team that simply wants a timer and an invoice, or for a company outside the DACH region with no compliance driver. The interface asks more of an administrator than newer tools do, the module structure rewards a company that will grow into it, and the ecosystem assumptions are unmistakably German. A five-person startup on a US finance stack will get further, faster, with something lighter.

How it compares

Toggl Track is far quicker to adopt and much better looking, but it stops at time and light reporting; it has nothing to say about statutory working-time documentation or DATEV. Clockify undercuts everyone on price and covers projects adequately, yet its invoicing and controlling remain shallow. Harvest sits closer to ZEP on billing but is built for the Anglo-American stack, so a German firm loses the accounting export that mattered most. Papershift and Clockodo compete directly inside Germany, generally with friendlier interfaces and narrower project depth, which is the trade ZEP consistently makes: more controlling, less polish.

Verdict

ZEP is a serious tool for a specific problem, hours that must satisfy both a labour inspector and a project margin report, and it has been doing that job long enough to have the edge cases covered. What holds the rating down is not capability but ergonomics and pricing clarity: menus that hide settings several levels deep, a mobile experience behind the browser, and a published price list of starting figures that grows once the necessary modules are added. For a DACH consultancy that bills by the hour it is a rational, unfashionable choice; for anyone outside that context the case largely disappears.
