Conversion to invoices is automatic with no chance for review

If you choose to convert orders to invoices using the To Do List window, keep in mind that the conversion will occur automatically; you won't get a chance to review or change any of the transactions before they're converted.

If you're not sure you want to convert a particular order, you should use the Sales window to make the conversion manually so you have better control over the sale than you would if you used the To Do List. [To convert an order to an invoice (Sales window)]
