For Top Rated Seller:
Sell at least 100 items within a 12 month period
Have at least $1,000 in sales within a 12 month period
90% of your ‘promised’ shipping and handling times you set for items you sell has been met in the last 3 months. Meaning if you sold 100 items, you need to have shipped out at least 90 of those orders in the promised time you set for delivery on your listing.
Sellers can only have a maximum 2% of transactions with one or more “defects” over the most recent evaluation period. (Sounds complicated, but as long as your description is accurate, buyers shouldn’t leave anything to impact this qualification)
You meet the eBay Money Back Guarantee and PayPal Purchase Protection case requirements (Again, sound complicated, eBay does a better job at detailing what these requirements mean entirely here, something that would be a separate guide on its own)
