WOLF4® offers comprehensive solutions for managing law firm revenue. This final part of the P.A.T.I. strategy (Plan, Action, Track, Income) enables easy processing of tracked work time into invoices and profitability analysis of assignments. With advanced reports and AI assistant support, the system quickly evaluates revenue sources and costs of serving individual clients. The module works flexibly – you can start by issuing an invoice without tracking work time, although the complete path from planning through implementation to settlement provides the best results.
