Bookseller ratings are calculated on a seller’s order completion rate over the past six months. Completion Rate = (Total Number of Order Items – Unfulfilled Order Items – Returned Order Items) / Total Number of Order Items
For example, if you had 75 orders, rejected 3 of them and had 2 returns, your completion rate would be 93%.
(75 – 3 – 2) = 70 / 75 = 93% completion rate
The completion rate percentages are translated into a five-star bookseller rating system that is displayed to buyers on AbeBooks.
96 – 100% = *****
90 – 95% = ****
85 – 89% = ***
70 – 84% = **
0 – 69% = *
The minimum standard for Completion is 90%. Booksellers who maintain a completion rate below the required minimum risk having their account suspended or closed.
Up to three orders can be excluded from your completion rating in a rolling 12-month period.
If you receive 3 or fewer orders in a 6 month rating period, and any of those orders are rejected or returned, your displayed rating will default to 4 stars. Once you receive 4 or more orders, your star rating will reflect your actual completion rate for the orders received during the 6 month rating period. If you complete all of the orders, for a Completion Rate of 100%, your rating will display as 5 stars, regardless of the number of orders received.
Any attempt to manipulate returns and/or completion rates by issuing refunds outside the AbeBooks system, and/or by a method other than the buyer’s original payment method, is a violation of AbeBooks Policy.
