Surprise?
Tech Data may be in the hot seat at the moment, but they certainly don't own the exclusive rights to dodgy bookkeeping in the tech distribution world. Everything about that industry fosters an environment of bad practices.
There's no good money in it for most participants, and the difference between eating and starving is the .025% extra you managed to cram into an order. Everybody is fighting for scraps and there is little differentiation between suppliers. They're all selling the same commodities and the only way to stand out is to cut your own throat and lower your margins. Anytime price is the primary target the only people who really benefit are those at the very top. There's nothing left for those in the middle.
The funny part to me is that the manufacturers could replace their channel partners easily enough and sell direct B2B, really beefing up their bottom lines. They could, but don't want to screw with it, it simply isn't worth the hassle. The people in the channel have been given the absolute worst role in the industry and new channel participants have to pay for the privilege. It isn't even sales, it is a brokerage.
Find something of high value to sell and get away from the sleazy channel. The money sucks and everything about it is dodgy.
