Homebase

Abebooks HomeBase is a free, yes totally free, management app that provides an offline or online bookstore inventory solution. The software takes care of everything from maintaining your inventory database, keeping track of buyers and issuing receipts, to uploading your active listings to sell on AbeBooks and other marketplaces such as Amazon. Price Partner is an application built into HomeBase 3.0 that allows you to modify the prices of multiple listings at once. You can increase or decrease prices by a percentage or by an absolute amount. If you have more than one copy of a book, you can use the quantity field and it automatically decrements the quantity online when a book is sold; no more manually re-listing! The software runs locally on your computer and requires the Windows operating system.

Up to 100 listings may be selected and edited/deleted at once. For example, if you realized you mis-typed an author's name on 5 listings, you could select them all and make the update once, and the edit would be applied to all 5 listings.

Some of the features for invoices include choosing whether taxes are included in your book prices or not, and the system will automatically calculate sub-totals and totals for you. The payment methods displayed are the acceptable ones you've set as preferences in HomeBase; and you can re-size and re-position the invoice columns.

Homebase is free to use.
