Time Tracking

Time tracking on construction sites was never easier

Put an end to time sheets on paper. Our market-leading mobile time tracking app allows your on-site team to easily record working times. Both individually and for an entire crew. The system automatically assigns the times to the corresponding construction sites, components and work areas. Recorded times, locations and activities are then digitally transferred to your office for real-time billing and daily construction reports. At the same time, the processed data can be shared with all project participants.

What's in it for you?

Your advantages on the job

It was a contractor who developed 123onsite. That's exactly why we fully understand the needs and requirements of the construction industry. Our goal has always been and still is to make your work easier, so you can focus on the really important tasks.

Record working time & save money on the go

Inefficient time tracking can end up costing your employees a lot of time and you a lot of money. But it doesn’t have to be that way. With 123onsite you can keep track of everything: whether in your office or on the road with a tablet or smartphone – you always know who is logged in on which construction site and what activities the employees are currently performing. You get daily, weekly and monthly reports documenting various processes. At the same time, our mobile time-tracking functionality expedites your post-calculation, invoicing and payroll operations.

Minimize errors thanks to reliable results

Incorrect time sheets on the construction site are a thing of the past thanks to mobile time tracking. You receive up-to-date and reliable information from your employees digitally, which can be used immediately for your payroll and construction reporting.

Record more hours for daily wages

Keep track of daily wages and additional work. As with project time sheets, you can record hours for per diem on virtual, online digital time sheets.

Document subcontractor performance

You can also record the work of your subcontractors. Similar to mobile time recording, you can subdivide your operations into additional levels, such as component and construction area. This gives you valuable reference points concerning your actual expenses in fixed-price contracts – which may prove to be useful insights for subsequent tendering negotiations.

Nothing but expenses?

Easily record expenses, travel costs, overnight and hotel stays via the app and transfer the data directly to payroll.
