You mention that you do a lot of networking..." I network constantly, belong to 3 or 4 business groups and send out monthly newsletters." I find it interesting that you mention these rather than the number of cold calls, phone calls, etc. Business groups and newsletters are supplemental but you can't rely on business to come to you from these sources.Business Groups are great for getting high-level contact names but you still have to make the calls.
You also said, "I also do all the web maintenance and marketing for the company." Are there other reps or are you the only one besides the owner? If you are the only one, then the work you do that's marketing largely benefits you. If you are not the only one, my attitude about this arrangement totally changes. Time you spend on website management is taking you away from making money. If they believe that your salary is your compensation for the website mgmt,, then why do you also have to cover it in sales before earning a commission?
I would also be curious to know if the owner's acct list is a finite list or does she handle anyone who calls in or walks in the door.
Ultimately, if you aren't making enough sales, you aren't covering enough ground. Good records are also imperative. If all you are trying to accomplish is the location of someone in the market, you'll end every day discouraged. Find out what they have, when they got it, whether they own it, and how satisfied they are with it. Then, based on the answers, determine a call back or follow-up schedule and stick to it. After three years in the business, you should have dozens of accounts every month that you determined months ago, might be prime for a return visit this month.
