TRACK YOUR ADVERTISING
If you advertise in several mediums, know which ones pay and which ones don't. When the phone rings, ask the caller how they heard of you: telephone book (which one); referral; a prior customer; direct mail; etc. Knowing the sources of service calls tells you where to put advertising dollars in the future for the greatest return. Your advertising must deliver a profitable "hit-rate".

IN-HOUSE TRAINING
When the phone slows down do you leave your techs in the field (just in case)?
Try leaving one truck in each zone and utilize this opportunity to train. Getting a class together when you have several techs working different schedules can be difficult. Classes are most efficient when you can talk to a group. You certainly don't want to train techs on their days off or after work. Forced training builds resentment and you'll have to pay your people for coming to work on their offtime. Instead, utilize the slow days to give sales classes and equipment training. Make your crew masters of the new technologies, product offerings and give basic plumbing classes. Discuss scenarios the techs are experiencing in the field. By monitoring daily sales invoices you can see "who sells what". Give a jetter class to those who always cable drains. Develop sales classes for those who deliver less than company minimums. Training enhances a technician's prospects for success in the field. Constantly re-enforce skill-levels and build upon them. Well trained techs who make a decent living are happier employees and that reduces employee turnover. Recruiting, interviewing and training new employees is a financial burden that can be lessened by reducing turnover. Hiring people to expand your business is a sign of success—hiring to fill a void because someone quit drags your profits down.
