The difference is profound, it is the difference between success and failure.
"But everyone needs lower prices, and I will work for less, and therefore succeed." No, you will not. Read on.
Here is an article out of the New York Times regarding Panjiva.com. The fellow explains the problem:
Let's give the devil his due. From the article we can extrapolate some numbers. I can imagine someone importing $36 million first cost (if true) in plastic bags and moving from supplier to supplier, as much as Rosenthal says he does, can find $1200 value in Panjiva. It sounds like he would need a full time person just to track down suppliers, so $1200 would be cheap. But I focus on the start up, and the $1200 would be a waste. (The story sounds doubtful, the shift to overseas for plastics bags started in the early 1980s, not 8 years ago.)
So the article goes on to speak glowingly of precisely the fundamental error in using such services:
I wish they would do follow-ups on these articles. A deal "in the bag" does not tell us much. Let's see how all this works out for Mr. Rosenthal in 4 years. In one instance of a follow up, it did not look so good.
And coincidentally I get a notice from Zepol.com:
The buzz at Zepol is all about U.S. export data. Yes, that's right, Zepol is currently developing phase two of our TradeIQ™ Export database. After launching phase one in August, we are thrilled to announce that the next phase will quadruple the number of U.S. export bills of lading available.
From generating new sales leads to competitive intelligence, Zepol's export data is delivering powerful insights every day. We are eager to deliver even more. Zepol will continue to send updates on our progress and an official launch date as it becomes available.
This is not the way to start. You must start earlier in the game, and follow the trade flows, follow the money. The article talks about difficult trade data. Well, it's not difficult, and I gladly send out a .pdf of instructions on how to get raw trade data, analyze it, and from there track down the best suppliers (in importing, or customers in exporting). Just email me I and I'll send it.
Now this all suggests to me yet another business opportunity. To wit: Customs pulls the suppliers name from the "shipper/supplier" box on the bill of lading. (this is partially why, as the article above notes, about half the data is useless). There is no legal requirement that that field name anyone in particular. Some companies knowing they'll end up in piers or panjiva list their freight forwarder or customs broker.
Now USCustoms does need a real entity named in that box, but in most places on earth a real entity can be a sheet of paper in a file folder. "Bob's Discount Heart Regulators." Should be some good money in that.
