Time record entries are automatically constructed using software modules and methods for presentation in response to telephone calls, whether made or received. Telephone call information is included in a memory and heuristics are applied to telephone call information to identify a billing reference for inclusion in the time record. The timekeeper has discretion whether to approve any proposed entries. Software tools are also disclosed to present and manage the automatically constructed time-record entries. The invention eliminates reliance upon the timekeeper to capture such activities as billable events in the first instance, and thereby can increase revenue opportunities.
