Awazon puts the two numbers that matter at the top of every vendor page. Reading them takes about a minute and it is the difference between an informed order and a hopeful one.
Deal count
How many orders the vendor has completed. A high count over time is a vendor the market has watched work. A brand-new account with a handful of orders is not disqualifying, but it is unproven, and a first order there should be especially small.
Dispute ratio
The share of orders that ended in a dispute. Low is good. A rising ratio on recent orders is a warning even on a vendor with a long clean history, so weight the recent pattern.
Finalise-early status
New vendors cannot use finalise-early until they have run clean orders, and the profile shows their standing. A vendor still in escrow-only is one the market has not yet extended that trust to, which is useful context.
