    Important features for craft businesses

    From measurement to invoice in one seamless digital process

    Take measurements on site, calculate with it, write an offer to the customer and use this to write order confirmations, activity records and convert them into an invoice. This is the process in work4all, into which industry-specific measurement programs can also be integrated via an interface.

    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

    In the craft sector, you probably have several small cases of “broken window handle” or “tile damaged” every day. These supposedly small cases 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 can also be recorded on the go with 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.

    Commercial overview of multiple projects

    The multi-project analysis in work4all clearly displays all projects with internal services, external services, revenues, and contribution margins. All information appears automatically: revenues from outgoing invoices, external services from incoming invoices, and internal services from recorded project hours. This way, you always have a live overview of the profitability of your projects.
