A Sales Account must be assigned to all items and stock items require an Expense, Inventory and Cost of Goods Sold account as well. Monthly, annual and one-time pricing is supported. Standard costing is used for stock items. Items can be designated as taxable by checking on the Taxable box. Items can be made unavailable for use in the system by unchecking the Active field. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
