Search your catalog
Open it from the Square Catalog card on the Dashboard (Search). Type an ISBN, title or author to find books you already carry, with price, quantity on hand, categories and SKU. Click a result to open the item in Square.
Index your catalog first
The first time you open it, click Index catalog. book by book reads your Square catalog so it can search it quickly; this takes a minute or two for a large catalog. After that the index keeps itself up to date as your catalog changes in Square.
Square Catalog search needs a paid plan after the trial.
