Easy Royalties stores the ISBN 10 as an ISBN 13 number. If you import an ISBN 10 and an ISBN 13 is already in the database it will consider this to be a match and will update the existing record if “Verify ISBN” is turned on in the system options screen. This royalty software functionality faciliates the import of historical sales that use the ISBN 10 product identifier.
When importing historical sales into Easy Royalties you need to assign a sales type of “historical” to each sales record. Historical sales are used to determine a starting escalator quantity and to report life to date sales dollars and quantities for each title. Royalty earnings are not calculated for historical sales records.
