20-40% has to be pretty nice. After costs, that still has to be a pretty tidy profit considering it's pretty easy repeat business. All it takes for a grocery store to get my business is maintaining clean carts and hand baskets. I'm at approximately 10-12% as an IT channel sales rep.. for serious accounts it's about 3% though. What I find severely offensive in my industry is that I have to pay to maintain certifications and continually obtain certifications to open new opportunities for both myself and my customer. I had one specific customer that was on vacation and needed some printheads ASAP for some weird label printers and he had called in and asked me to find them for him. - I called the company and got the models on the printers - I called the manufacturer and found out there were two versions of the printhead.. one 600 ohms one 700 ohms - I set my company up as a direct vendor for the printer company (we had to get authorization through Ingram Micro) - I called the company again and walked them through finding the part #'s of the ink they were currently using - I sent over a quote to the company and waited on a PO (I had them on Net Terms) All of this took about two hours of my time, time where I didn't get a single sale from another customer. I followed up on the PO two hours later knowing that they needed these printheads ASAP. My customer told his office to google the manufacturing part numbers I had given them and to order them. The google price ended up being around $5400. My price was $5500. I could have matched, or even beat the price.. not that I would have. But I was never even given the opportunity after all of my work. I ended up thanking that customer for all of his previous business and stated that I simply couldn't continue doing business with his company if he didn't value my time. I ended up passing that account on to a newbie. I don't mind being priced out when I'm not doing any work, but when I'm doing all the work it's extremely offensive. Anyways, I tend to be a pretty decent tipper. I don't care for the math thing. I tip $5 for my girlfriend and myself as long as they routinely refill my drink. If we're somewhere nice I'll tip $7-15. If it's breakfast, it's $3.00. Pizza guy always gets $3 (I've been told it's above average anyways), carry out always gets $2. If all I have is a $5.00 bill though, that's what they'll get. I think the haircut place actually fights over me, I'm in there about 15 times a year, am done within 15 minutes, Ialways get the same haircut and always tip them $5. I'm not rich by any means, but I remember back when I had to slave away to make a living. I figure if I can make someones day a little better there's no harm. I know I'm not any worse for the wear.
