As a wagon jobber, you offer the technicians several benefits that other merchants can’t or won’t. Things like on-the-spot sales/service, repair or replacement of broken products, specialty products that are very hard to find elsewhere, a wide variety of products, excellent credit terms, and the knowledge to present the right tool for the job to be done. What you cannot do is compete on price. Therefore, you darn well must be a better salesperson than any online picture or description, and significantly better than the next mobile jobber coming through the door.
Let’s get to the point. If you want to sell more stuff, make your calls, give great demonstrations, and ask for the order. Do that enough times and you will sell something. Do it better and better each time and you will make more sales.
