Would love a Job Tracking feature to help keep track of open jobs. At minimum, create additional Statuses for a job. For example, once a job is accepted move the job to scheduling, once the job has been marked as scheduled, move it to in progress.
A full job tracking system would be great, i love the direction Portal takes, being easy to use and navigate, and would love an end to end solutions from CRM to quoting, scheduling, payments, job tracking, customer tracking, etc.
