Quick answer: Some NPC vendors sell items for a fixed gil price that resell much higher on the market board. Vendor flipping is buying those, listing them, and pocketing the spread after the 5% tax. Gated shops (tribe, event) keep the best margins because fewer players can reach the supply; the reverse — selling cheap board items back to NPCs — also works.
Somewhere in Final Fantasy XIV there is a merchant selling an item for a fixed handful of gil that players are paying many times that for on the market board. Buying it from the NPC and listing it yourself is the simplest gil method in the game — no crafting, no gathering, no combat. The entire skill is knowing which items, on your world, right now.
It feels like it shouldn't work. The item has a fixed price and unlimited supply — why would anyone pay more? Because the price tag isn't the real cost. The real cost is knowing the item exists, knowing which NPC in which zone stocks it, having that zone unlocked, and making the trip. Players buying on the board are paying you for all four.
The gaps that create margin, roughly in order of how durable they are:
Every board sale is taxed 5%, and that comes off the sale price, not off your profit. So the real per-unit number is:
A 1,000 gil item bought for 200 nets 750, not 800. That 5% barely matters on a wide flip and quietly kills a narrow one — a 6% spread is a 1% business.
This is the thing that makes vendor flipping different from every other kind of trading. Gil vendors never run out and never need to restock. That has two consequences:
Which is why the gated items matter so much. A flip protected by a reputation rank or an unusual currency stays profitable far longer, because the pool of people who can undercut you is small.
Categories that come up again and again, on every world:
Our vendor dataset holds 26,282 shop listings across 255 NPCs in 90 zones, and 4,943 marketable items that an NPC will sell you for gil. That's the candidate pool. On any given day a small fraction of it is worth flipping on your world — which is exactly the kind of filtering worth handing to a tool.
NPC to Market Flips checks every one of those vendor prices against live board prices on your world, takes the 5% tax off the top, and ranks what's left by profit. The vendor database is the browsing version — pick a merchant, see their whole catalog with current market values.
Almost every item has a second price attached to it — what an NPC will pay you for it. It's usually far below market, so it's usually irrelevant.
Every so often a market price falls under that buy-back price: someone dumps a stack to clear retainer space, an undercut war spirals, a hoard gets liquidated. Buy those listings, walk to any merchant, sell them, and pocket a guaranteed spread. Selling to an NPC is never taxed, and there's no waiting for a buyer — the gil is instant and the trade carries no market risk at all.
17,117 marketable items have a buy-back price, so the search space is large and the windows are short. Market to NPC Flips scans for them.
