HandiFox features the ability to create Sales Orders, which are used to keep record of product orders placed by your customers and track quantities on order and quantities available for your inventory items. Invoices can be auto-filled based on sales orders, and Picking/Packing  can be done to verify that the correct items are shipped.
 

 QuickBooks Online now has sales orders, but at this point in time, QuickBooks sales orders are not synchronized to HandiFox. Likewise, sales orders created in HandiFox do not synchronize to QuickBooks. This is due to limitations and issues with the QuickBooks API, which make synchronization of sales orders impossible at the moment.
