We're a small company. Our installers and sales reps act as a team to complete projects they do together. Sometimes they are able to spend time going over a job before the final proposal (usually larger jobs); other times, the installer only sees the project after the sale. The sales person designs the job and puts together a rough parts list and it's reviewed by the installer before ordering (by an in-house technician). For a variety of reasons, the original parts too often require a change. Too often, this requires phone calls and research to find the right part and review the specs, codes, etc. Our installers also serve as limited project managers, co-ordinating schedules, sub-contractors, etc. Who do you have finalize the parts list - the person who designs/sells or the technician who installs it? Since site time is valuable, there's concern with the office/phone/computer time required to research/engineer the final parts list/design. Any insights on how things are handled at different companies would be appreciated.
Thanks!
