In detail, with examples: Working hours in temporary agency work: what agencies and hirers have to record
As at: November 2026. This is not legal advice; for a specific case in your business it is better to ask someone with a licence to practise.
Two sides have to hold the same hours
Under § 17c (1) AÜG the hirer records the start, the end and the duration of your temporary workers' daily working time. If your hours account differs, it only shows up at invoicing.
- Problem
The record sits with the hirer
Under § 17c (1) AÜG the hirer records the start, the end and the duration, but you are the one who has to invoice and prove it.
- Problem
The seven-day deadline applies here too
The record has to exist by the end of the seventh calendar day after the work. Adding entries at the month end is too late.
- Problem
The records have to be to hand
The agency keeps the inspection records in German within Germany, and at the place of work on request (§ 17c (2) AÜG).
An hours account that matches the hirer's
Every assignment runs as its own client with its own hours. Your people book on a phone, you see target and actual per person, and you export the hours per hirer and month.
Hours per hirer, on the recordThe start, the end and the duration are on file per person and assignment, ready when the hirer or an inspection asks.
From the assignment to the invoice
Three steps that put the hours per hirer on the record.
Assign people to the assignment
Every hirer is created as a client and every assignment as a project under it. Your people see only their own assignments.
The hours are kept apart per hirer from the start.
Assignment by placement Valid from a set date
A new model starts on a date. Everything before keeps counting with the old one.
For several at once
Apply the change and watch it switch row by row.

What staffing providers need
Many hirers, changing assignments, one invoice, with no folder to collect it in.

The same three figures the hirer records under § 17c AÜG.
Breaks are recorded too and deducted from working time.
- Projects
Kept apart per hirer
Every hirer is a client, and every assignment a project under it.
The hours can be reported per hirer, assignment and person.

Frequent questions from temporary work
The recording duty, the deadlines and reconciling with the hirer, answered briefly.
Question not answered here? Every step is explained in the help centre.
Send us a messageWho has to record temporary workers' working time?
Under § 17c (1) AÜG the hirer records the start, the end and the duration of the daily working time, by the end of the seventh calendar day afterwards at the latest, kept for at least two years. But you as the agency have to invoice and evidence it, which is why you need the same figures.
How do I keep the records the way the AÜG requires?
Under § 17c (2) AÜG the inspection records have to be available in German within Germany, and at the place of work on request. MetronHR runs on German servers, the reports are in German and they can be retrieved from any device.
Can I report hours separately per hirer?
Yes. Every hirer is created as a client and every assignment as a project under it. In the report you filter by hirer, assignment, person and period and download the result as Excel or CSV.
What if somebody does not book their own hours?
Anyone leading a department or with people under them can create time entries for them. So the scheduler enters for people out on assignment. Management may record for everybody.
Do my people see their colleagues' assignments?
No. People see their own hours and assignments. Who has access to anything further you control through roles and departments, which stays clean even with changing hirers.
What does it cost when headcount fluctuates?
Billing is per user per month: Team 5 €, Professional 10 €. Time tracking with customer assignment, absences, overtime, working-time models and Excel/CSV export are included in the Team plan; analytics, the personnel file and the change history of time entries are part of Professional.
