Even though this thread is 11 years old, it all still holds true. I sell custom parts on another forum, and I only accept money orders ( you will be charged a $60 fee for a money order, they are hard to cash around here for some reason) or paypal. No cash, ever. I also update my customers frequently. A lot of them like to have a timeline of photos, they feel like they are there while their parts are being machined. When I build an engine, I take detailed photos of everything inside and out, not only to please my customers, but for my own protection. It's proof of what they are getting, no shenanigans. I'm only one man, with a normal job, and make stuff on the side, because I love doing it. Yeah, ok, some of it is for the money, but most of it is because I love it. I'm glad most my customers are really cool, some of my work can take up to 2 months to be made, I try to keep a supply on hand, but the last 2 years have been hard to stay stocked 100% of the time. If I cannot build your item, I will not take your money until I can. I also only work on 1 or 2 orders at a time, and everyone else goes on waiting list, and when their number comes up, they can decided to pay or pass, and I move to the next job, or wait for their money to show and start their items. In the hobby I sell stuff in, a lot of vendors are very shady and will take your money and sit on it for a year or more, then just tell you " oh well". I will never do that, I hate it when it's done to me, and I only want my customer to be happy with what they ordered. If they are not happy, I do what I have to to make it right. So far, I have 100% happy customers. I plan to keep it that way.
