One thing I learned on this thread is it must not be a lot of fun to be in the repair business with all the supply chain nonsense!
That is basically it. When I first start the business things were simple but in the last few years it is taking more and more time to jump through all hoops vendors are putting my way taking away from actual repair time and normal bookkeeping.
Like one vendor all a sudden started demanding me to buy X dollars of part from every year if I needed or not. They the low volume themselves by selling defective products and had salespersons that would not reply to emails and telcon messages. I had to find other vendors to take up their slack.
Now I got one that refuses to explain an excessive shipping charge and trying to force me to accept ads by making accepting cookies mandatory; no opt out offered.
And there are distributor of certain OEM parts that are only certain lines of parts and then I have to look for another vendor or distributor for the rest of the parts. And then if want to save on parts costs it gets even worst like the JD LA115 that I got 7 different vendors involved for the parts; all for a $500 repair. If had use just JD then repairs would a lot closer to $1000.
