Important features for security technology and burglary protection

Write offers based on articles and simply convert

Based on the items in work4all, which you can easily import from your suppliers, you write offers in work4all. These can then be converted into order confirmations, activity records or invoices via drag & drop. Of course, the offer can also be calculated.

Have service reports digitally signed by the customer

With the work4all app, you can have service reports or delivery notes signed on-site at the customer’s location using your tablet. The service reports can then be billed in work4all by customer or project – a fully digital process.

Ticket management for high service quality

“Key broken”, “Door no longer opens”... You know these inquiries from customers. These supposedly small cases, which take up a lot of time, show the quality of your organization. work4all's ticket management helps you to record these cases cleanly, keep track of them, plan appointments and bill them cleanly.

Mobile time tracking for field staff

Project hours are recorded directly on-site, e.g., at the construction site, using the work4all app. The tedious task of entering hours later in the office is now a thing of the past. In the desktop version of work4all, the hours can then be converted into service reports or invoices. Together with external services (incoming invoices), all project costs are visible in real time.
