If you choose, MYOB AccountEdge allows you to add useful information about your purchase, such as a journal entry memo or a shipping method. If you'd like, you can use the vendor's card to set default entries for several fields in the Purchases window. See Buying Details view (Vendor cards only) for more information.
The tax code that is selected for the vendor using the Buying Details view of the Card Information window is entered automatically when the vendor card is entered in the Purchases window. You can change it, if you wish. Using the Buying Details view of the Item Information window, you can choose to mark automatically an item that's included in the Items List to be taxed when you enter the item on a purchase. Simply mark I Pay Sales Tax When I Buy This Item.
All parts of the purchase (line items and freight charges) that you've marked as taxable will be taxed based on the sales tax code's tax rate. If, after you've entered all your line items and freight charges, the sales tax amount that appears in the Tax field isn't the amount that the vendor is billing, you may want to manually adjust the amount. Click the arrow next to the Tax field to open the Tax Information window; you can adjust the amount in the Tax column.
