BS/1 Professional is an integrated time billing and accounting system that includes accounts payable, accounts receivable, general ledger, inventory, time billing and sales analysis. Client projects/jobs are tracked by priority and due date, and time is billed against the tasks that make up a job. A stopwatch and time calculator are included. The system comes with sample data for a quick overview of its capabilities, and an optional Getting Started wizard will assist you with entering initial live data. The wizard sets up common GL accounts that can later be changed, deleted or added to.
