Frequently asked questions regarding 123quality

For whom is the defect management app designed?

Defect management occurs on every construction site. Therefore, 123quality is suitable for all trades on the construction site and anyone who wants to keep an eye on them from the office. Our customers include construction companies, architects’ offices, planning offices and workshops of all sizes.

Can 123quality be combined with 123onsite?

Are you already using 123onsite for time recording or your daily reports? Then you can easily get 123quality enabled – because the solution is already integrated into 123onsite, and you therefore you do not require two separate apps. The advantage is that you can access all captured data and use it
to work efficiently. For example, if you create a ticket in 123quality, you can directly record the time spent on it in 123onsite, e.g., to quantify the costs of rectifying the defect. However, you can also use 123quality without 123onsite – completely flexible and exactly in accordance with your needs.

How many licenses do I need if several of my employees want to use 123quality?

In our defect management app, we distinguish between “ticket creators” and “ticket processors”. For each entry-level license that you activate with us, one employee can create tickets on the construction site and use them to record defects. Within the license, however, tickets can be assigned to an unlimited number of ticket processors, e.g. additional employees or subcontractors for defect processing. Want more than one person in your organization to be able to create tickets? Then opt for a Professional or Enterprise license, which allow more ticket creators to be enabled.
