Used for accounting and reporting, you can link sales categories to your departments and then when setting up an accounting integration you can link your sales categories to your general ledger codes in your accounting package therefore pushing department sales through to accounting. You can also pull detailed reports by using sales categories as an extra category/filter to break down sales.
The Sales Category screen looks like the below and can be found under “File > Sales > Sales Categories”
You can create as many sales categories as you want however a maximum of 9 can be sent through to accounting
