Important functions for IT service providers and system houses

Ticket management

The integrated ticket management is the big plus of work4all for IT service providers. By drag & drop or fully automatically, the customer's email is turned into a ticket, which also shows the status of the service contract. Programming assignments and sales tasks can also be controlled via the tickets.

Paid support is tracked over time and can then be automatically billed monthly.

Time tracking including automatic billing

work4all project time tracking is as flexible as you need. Data can be tracked in the work4all app, in the work4all desktop version, in the browser or at terminals — wherever you are currently working.

For some IT service providers, the times only serve as an internal barometer of expenses, for others as billable service hours. The recorded hours can be automatically billed with project billing.

Collective billing of service contracts

To maintain and support software or maintenance, you conclude service contracts with your customers, which are billed regularly. Our subscription module automates this process as much as possible. All due service invoices are created at the push of a button. Service invoices can also be sent by email or printed out in one fell swoop.

If support services are billed according to actual expenditure, our project billing is the right solution for you.
