I wanted to give the guild some basic understanding of how trade functions work in ESO. First, imho they are total garbage, but they are what they are.
1. As you know we have a store this is step one, the store is only guild members unless you have a trader. The store is tied to having at least 50 members.
2. Guilds can hire a guild trader, this gives your guild store an outward facing NPC. What that means is anyone in the game can by items from this NPC in game.
3. To get this NPC, guilds have to bid each week, biding ends each Sunday. The bids are all blind so there is no way to know how much you have to bid. They are in gold, and it is very competitive, with around 197 traders in game period.
4. In general to get one will be upwards of 1 million gold. If you win a bid you get the trader for 1 week only. You have to rebid each week.
5. You can get a trader for your faction only via taking a keep in PvP, that is a whole other story and not part of this post.
6. The guild does get an automatic cut of all sales in the store, this cut is not very big its around 3.5% of the sell price.
7. The guild trade bid if you win is gone, ie that gold is paid to the game.
8. The only way guilds make gold is to have it donated, or via sales.
9. We have a plan in place to try and create a stable guild trade network, this is found here, but will take time. It may work, it may not. Still the goal is a sustainable trade environment that at a minimum breaks even.
10. As you know we are not a "trade guild". We also will never charge fees to be in the our guild ect. There is little reason to have a trader when it can not at least pay for itself.
So that is the basics of guild trade, the math is pretty easy to do.
