Can I allocate invoiced income to different funds and categories?
When creating invoices you can choose to allocate the income to as many different funds and categories as you like. It does not matter how many itemised 'line items' you include on the invoice.
Scroll to the bottom of the 'Create Invoice' screen, within the Income Allocation section, use the drop-down menus to select the funds and then the income categories you need.
